memory: tegra: Add memory controller channels support
From Tegra186 onwards, the memory controller supports multiple channels. Add support for mapping the address spaces of these channels and specify the number of channels supported by Tegra186, Tegra194 and Tegra234. In case of old bindings, channels won't be present. If channels are not present then print a warning and continue so that backward compatibility will be preserved in driver. During error interrupts from memory controller, appropriate registers from these channels need to be accessed for logging error info.

soc: rockchip: power-domain: Manage resource conflicts with firmware
On RK3399 platforms, power domains are managed mostly by the kernel
(drivers/soc/rockchip/pm_domains.c), but there are a few exceptions
where ARM Trusted Firmware has to be involved:
(1) system suspend/resume
(2) DRAM DVFS (a.k.a., "ddrfreq")
Exception (1) does not cause much conflict, since the kernel has
quiesced itself by the time we make the relevant PSCI call.
Exception (2) can cause conflict, because of two actions:
(a) ARM Trusted Firmware needs to read/modify/write the PMU_BUS_IDLE_REQ
register to idle the memory controller domain; the kernel driver
also has to touch this register for other domains.
(b) ARM Trusted Firmware needs to manage the clocks associated with
these domains.
To elaborate on (b): idling a power domain has always required ungating
an array of clocks; see this old explanation from Rockchip:
https://lore.kernel.org/linux-arm-kernel/54503C19.9060607@rock-chips.com/
Historically, ARM Trusted Firmware has avoided this issue by using a
special PMU_CRU_GATEDIS_CON0 register -- this register ungates all the
necessary clocks -- when idling the memory controller. Unfortunately,
we've found that this register is not 100% sufficient; it does not turn
the relevant PLLs on [0].
So it's possible to trigger issues with something like the following:
1. enable a power domain (e.g., RK3399_PD_VDU) -- kernel will
temporarily enable relevant clocks/PLLs, then turn them back off
2. a PLL (e.g., PLL_NPLL) is part of the clock tree for
RK3399_PD_VDU's clocks but otherwise unused; NPLL is disabled
3. perform a ddrfreq transition (rk3399_dmcfreq_target() -> ...
drivers/clk/rockchip/clk-ddr.c / ROCKCHIP_SIP_DRAM_FREQ)
4. ARM Trusted Firmware unagates VDU clocks (via PMU_CRU_GATEDIS_CON0)
5. ARM Trusted firmware idles the memory controller domain
6. Step 5 waits on the VDU domain/clocks, but NPLL is still off
i.e., we hang the system.
So for (b), we need to at a minimum manage the relevant PLLs on behalf
of firmware. It's easier to simply manage the whole clock tree, in a
similar way we do in rockchip_pd_power().
For (a), we need to provide mutual exclusion betwen rockchip_pd_power()
and firmware. To resolve that, we simply grab the PMU mutex and release
it when ddrfreq is done.
The Chromium OS kernel has been carrying versions of part of this hack
for a while, based on some new custom notifiers [1]. I've rewritten as a
simple function call between the drivers, which is OK because:
* the PMU driver isn't enabled, and we don't have this problem at all
(the firmware should have left us in an OK state, and there are no
runtime conflicts); or
* the PMU driver is present, and is a single instance.
And the power-domain driver cannot be removed, so there's no lifetime
management to worry about.
For completeness, there's a 'dmc_pmu_mutex' to guard (likely
theoretical?) probe()-time races. It's OK for the memory controller
driver to start running before the PMU, because the PMU will avoid any
critical actions during the block() sequence.
[0] The RK3399 TRM for PMU_CRU_GATEDIS_CON0 only talks about ungating
clocks. Based on experimentation, we've found that it does not power
up the necessary PLLs.
[1] CHROMIUM: soc: rockchip: power-domain: Add notifier to dmc driver
https://chromium-review.googlesource.com/q/I242dbd706d352f74ff706f5cbf42ebb92f9bcc60
Notably, the Chromium solution only handled conflict (a), not (b).
In practice, item (b) wasn't a problem in many cases because we
never managed to fully power off PLLs. Now that the (upstream) video
decoder driver performs runtime clock management, we often power off
NPLL.

net: dsa: felix: perform MDB migration based on ocelot->multicast list
The felix driver is the only user of dsa_port_walk_mdbs(), and there isn't even a good reason for it, considering that the host MDB entries are already saved by the ocelot switch lib in the ocelot->multicast list. Rewrite the multicast entry migration procedure around the ocelot->multicast list so we can delete dsa_port_walk_mdbs().

net: mscc: ocelot: mark traps with a bool instead of keeping them in a list
Since the blamed commit, VCAP filters can appear on more than one list.
If their action is "trap", they are chained on ocelot->traps via
filter->trap_list. This is in addition to their normal placement on the
VCAP block->rules list head.
Therefore, when we free a VCAP filter, we must remove it from all lists
it is a member of, including ocelot->traps.
There are at least 2 bugs which are direct consequences of this design
decision.
First is the incorrect usage of list_empty(), meant to denote whether
"filter" is chained into ocelot->traps via filter->trap_list.
This does not do the correct thing, because list_empty() checks whether
"head->next == head", but in our case, head->next == head->prev == NULL.
So we dereference NULL pointers and die when we call list_del().
Second is the fact that not all places that should remove the filter
from ocelot->traps do so. One example is ocelot_vcap_block_remove_filter(),
which is where we have the main kfree(filter). By keeping freed filters
in ocelot->traps we end up in a use-after-free in
felix_update_trapping_destinations().
Attempting to fix all the buggy patterns is a whack-a-mole game which
makes the driver unmaintainable. Actually this is what the previous
patch version attempted to do:
https://patchwork.kernel.org/project/netdevbpf/patch/20220503115728.834457-3-vladimir.oltean@nxp.com/
but it introduced another set of bugs, because there are other places in
which create VCAP filters, not just ocelot_vcap_filter_create():
- ocelot_trap_add()
- felix_tag_8021q_vlan_add_rx()
- felix_tag_8021q_vlan_add_tx()
Relying on the convention that all those code paths must call
INIT_LIST_HEAD(&filter->trap_list) is not going to scale.
So let's do what should have been done in the first place and keep a
bool in struct ocelot_vcap_filter which denotes whether we are looking
at a trapping rule or not. Iterating now happens over the main VCAP IS2
block->rules. The advantage is that we no longer risk having stale
references to a freed filter, since it is only present in that list.
Fixes:

net: ethernet: ocelot: remove the need for num_stats initializer
There is a desire to share the oclot_stats_layout struct outside of the current vsc7514 driver. In order to do so, the length of the array needs to be known at compile time, and defined in the struct ocelot and struct felix_info. Since the array is defined in a .c file and would be declared in the header file via: extern struct ocelot_stat_layout[]; the size of the array will not be known at compile time to outside modules. To fix this, remove the need for defining the number of stats at compile time and allow this number to be determined at initialization.

Networking changes for 5.18.
Core
----
- Introduce XDP multi-buffer support, allowing the use of XDP with
jumbo frame MTUs and combination with Rx coalescing offloads (LRO).
- Speed up netns dismantling (5x) and lower the memory cost a little.
Remove unnecessary per-netns sockets. Scope some lists to a netns.
Cut down RCU syncing. Use batch methods. Allow netdev registration
to complete out of order.
- Support distinguishing timestamp types (ingress vs egress) and
maintaining them across packet scrubbing points (e.g. redirect).
- Continue the work of annotating packet drop reasons throughout
the stack.
- Switch netdev error counters from an atomic to dynamically
allocated per-CPU counters.
- Rework a few preempt_disable(), local_irq_save() and busy waiting
sections problematic on PREEMPT_RT.
- Extend the ref_tracker to allow catching use-after-free bugs.
BPF
---
- Introduce "packing allocator" for BPF JIT images. JITed code is
marked read only, and used to be allocated at page granularity.
Custom allocator allows for more efficient memory use, lower
iTLB pressure and prevents identity mapping huge pages from
getting split.
- Make use of BTF type annotations (e.g. __user, __percpu) to enforce
the correct probe read access method, add appropriate helpers.
- Convert the BPF preload to use light skeleton and drop
the user-mode-driver dependency.
- Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
its use as a packet generator.
- Allow local storage memory to be allocated with GFP_KERNEL if called
from a hook allowed to sleep.
- Introduce fprobe (multi kprobe) to speed up mass attachment (arch
bits to come later).
- Add unstable conntrack lookup helpers for BPF by using the BPF
kfunc infra.
- Allow cgroup BPF progs to return custom errors to user space.
- Add support for AF_UNIX iterator batching.
- Allow iterator programs to use sleepable helpers.
- Support JIT of add, and, or, xor and xchg atomic ops on arm64.
- Add BTFGen support to bpftool which allows to use CO-RE in kernels
without BTF info.
- Large number of libbpf API improvements, cleanups and deprecations.
Protocols
---------
- Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.
- Adjust TSO packet sizes based on min_rtt, allowing very low latency
links (data centers) to always send full-sized TSO super-frames.
- Make IPv6 flow label changes (AKA hash rethink) more configurable,
via sysctl and setsockopt. Distinguish between server and client
behavior.
- VxLAN support to "collect metadata" devices to terminate only
configured VNIs. This is similar to VLAN filtering in the bridge.
- Support inserting IPv6 IOAM information to a fraction of frames.
- Add protocol attribute to IP addresses to allow identifying where
given address comes from (kernel-generated, DHCP etc.)
- Support setting socket and IPv6 options via cmsg on ping6 sockets.
- Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
Define dscp_t and stop taking ECN bits into account in fib-rules.
- Add support for locked bridge ports (for 802.1X).
- tun: support NAPI for packets received from batched XDP buffs,
doubling the performance in some scenarios.
- IPv6 extension header handling in Open vSwitch.
- Support IPv6 control message load balancing in bonding, prevent
neighbor solicitation and advertisement from using the wrong port.
Support NS/NA monitor selection similar to existing ARP monitor.
- SMC
- improve performance with TCP_CORK and sendfile()
- support auto-corking
- support TCP_NODELAY
- MCTP (Management Component Transport Protocol)
- add user space tag control interface
- I2C binding driver (as specified by DMTF DSP0237)
- Multi-BSSID beacon handling in AP mode for WiFi.
- Bluetooth:
- handle MSFT Monitor Device Event
- add MGMT Adv Monitor Device Found/Lost events
- Multi-Path TCP:
- add support for the SO_SNDTIMEO socket option
- lots of selftest cleanups and improvements
- Increase the max PDU size in CAN ISOTP to 64 kB.
Driver API
----------
- Add HW counters for SW netdevs, a mechanism for devices which
offload packet forwarding to report packet statistics back to
software interfaces such as tunnels.
- Select the default NIC queue count as a fraction of number of
physical CPU cores, instead of hard-coding to 8.
- Expose devlink instance locks to drivers. Allow device layer of
drivers to use that lock directly instead of creating their own
which always runs into ordering issues in devlink callbacks.
- Add header/data split indication to guide user space enabling
of TCP zero-copy Rx.
- Allow configuring completion queue event size.
- Refactor page_pool to enable fragmenting after allocation.
- Add allocation and page reuse statistics to page_pool.
- Improve Multiple Spanning Trees support in the bridge to allow
reuse of topologies across VLANs, saving HW resources in switches.
- DSA (Distributed Switch Architecture):
- replay and offload of host VLAN entries
- offload of static and local FDB entries on LAG interfaces
- FDB isolation and unicast filtering

Merge tag 'net-next-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"The sprinkling of SPI drivers is because we added a new one and Mark
sent us a SPI driver interface conversion pull request.
Core
----
- Introduce XDP multi-buffer support, allowing the use of XDP with
jumbo frame MTUs and combination with Rx coalescing offloads (LRO).
- Speed up netns dismantling (5x) and lower the memory cost a little.
Remove unnecessary per-netns sockets. Scope some lists to a netns.
Cut down RCU syncing. Use batch methods. Allow netdev registration
to complete out of order.
- Support distinguishing timestamp types (ingress vs egress) and
maintaining them across packet scrubbing points (e.g. redirect).
- Continue the work of annotating packet drop reasons throughout the
stack.
- Switch netdev error counters from an atomic to dynamically
allocated per-CPU counters.
- Rework a few preempt_disable(), local_irq_save() and busy waiting
sections problematic on PREEMPT_RT.
- Extend the ref_tracker to allow catching use-after-free bugs.
BPF
---
- Introduce "packing allocator" for BPF JIT images. JITed code is
marked read only, and used to be allocated at page granularity.
Custom allocator allows for more efficient memory use, lower iTLB
pressure and prevents identity mapping huge pages from getting
split.
- Make use of BTF type annotations (e.g. __user, __percpu) to enforce
the correct probe read access method, add appropriate helpers.
- Convert the BPF preload to use light skeleton and drop the
user-mode-driver dependency.
- Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
its use as a packet generator.
- Allow local storage memory to be allocated with GFP_KERNEL if
called from a hook allowed to sleep.
- Introduce fprobe (multi kprobe) to speed up mass attachment (arch
bits to come later).
- Add unstable conntrack lookup helpers for BPF by using the BPF
kfunc infra.
- Allow cgroup BPF progs to return custom errors to user space.
- Add support for AF_UNIX iterator batching.
- Allow iterator programs to use sleepable helpers.
- Support JIT of add, and, or, xor and xchg atomic ops on arm64.
- Add BTFGen support to bpftool which allows to use CO-RE in kernels
without BTF info.
- Large number of libbpf API improvements, cleanups and deprecations.
Protocols
---------
- Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.
- Adjust TSO packet sizes based on min_rtt, allowing very low latency
links (data centers) to always send full-sized TSO super-frames.
- Make IPv6 flow label changes (AKA hash rethink) more configurable,
via sysctl and setsockopt. Distinguish between server and client
behavior.
- VxLAN support to "collect metadata" devices to terminate only
configured VNIs. This is similar to VLAN filtering in the bridge.
- Support inserting IPv6 IOAM information to a fraction of frames.
- Add protocol attribute to IP addresses to allow identifying where
given address comes from (kernel-generated, DHCP etc.)
- Support setting socket and IPv6 options via cmsg on ping6 sockets.
- Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
Define dscp_t and stop taking ECN bits into account in fib-rules.
- Add support for locked bridge ports (for 802.1X).
- tun: support NAPI for packets received from batched XDP buffs,
doubling the performance in some scenarios.
- IPv6 extension header handling in Open vSwitch.
- Support IPv6 control message load balancing in bonding, prevent
neighbor solicitation and advertisement from using the wrong port.
Support NS/NA monitor selection similar to existing ARP monitor.
- SMC
- improve performance with TCP_CORK and sendfile()
- support auto-corking
- support TCP_NODELAY
- MCTP (Management Component Transport Protocol)
- add user space tag control interface
- I2C binding driver (as specified by DMTF DSP0237)
- Multi-BSSID beacon handling in AP mode for WiFi.
- Bluetooth:
- handle MSFT Monitor Device Event
- add MGMT Adv Monitor Device Found/Lost events
- Multi-Path TCP:
- add support for the SO_SNDTIMEO socket option
- lots of selftest cleanups and improvements
- Increase the max PDU size in CAN ISOTP to 64 kB.
Driver API
----------
- Add HW counters for SW netdevs, a mechanism for devices which
offload packet forwarding to report packet statistics back to
software interfaces such as tunnels.
- Select the default NIC queue count as a fraction of number of
physical CPU cores, instead of hard-coding to 8.
- Expose devlink instance locks to drivers. Allow device layer of
drivers to use that lock directly instead of creating their own
which always runs into ordering issues in devlink callbacks.
- Add header/data split indication to guide user space enabling of
TCP zero-copy Rx.
- Allow configuring completion queue event size.
- Refactor page_pool to enable fragmenting after allocation.
- Add allocation and page reuse statistics to page_pool.
- Improve Multiple Spanning Trees support in the bridge to allow
reuse of topologies across VLANs, saving HW resources in switches.
- DSA (Distributed Switch Architecture):
- replay and offload of host VLAN entries
- offload of static and local FDB entries on LAG interfaces
- FDB isolation and unicast filtering

are merged through different trees.
- Long abandoned support for running NOMMU ARMv4 or ARMv5 platforms
gets removed, now the Arm NOMMU platforms are limited to the
Cortex-M family of microcontrollers
- Two old PXA boards get removed, along with corresponding driver
bits.

net: mscc: ocelot: offload per-flow mirroring using tc-mirred and VCAP IS2
Per-flow mirroring with the VCAP IS2 TCAM (in itself handled as an offload for tc-flower) is done by setting the MIRROR_ENA bit from the action vector of the filter. The packet is mirrored to the port mask configured in the ANA:ANA:MIRRORPORTS register (the same port mask as the destinations for port-based mirroring). Functionality was tested with: tc qdisc add dev swp3 clsact tc filter add dev swp3 ingress protocol ip \ flower skip_sw ip_proto icmp \ action mirred egress mirror dev swp1 and pinging through swp3, while seeing that the ICMP replies are mirrored towards swp1.

net: mscc: ocelot: add port mirroring support using tc-matchall
Ocelot switches perform port-based ingress mirroring if ANA:PORT:PORT_CFG field SRC_MIRROR_ENA is set, and egress mirroring if the port is in ANA:ANA:EMIRRORPORTS. Both ingress-mirrored and egress-mirrored frames are copied to the port mask from ANA:ANA:MIRRORPORTS. So the choice of limiting to a single mirror port via ocelot_mirror_get() and ocelot_mirror_put() may seem bizarre, but the hardware model doesn't map very well to the user space model. If the user wants to mirror the ingress of swp1 towards swp2 and the ingress of swp3 towards swp4, we'd have to program ANA:ANA:MIRRORPORTS with BIT(2) | BIT(4), and that would make swp1 be mirrored towards swp4 too, and swp3 towards swp2. But there are no tc-matchall rules to describe those actions. Now, we could offload a matchall rule with multiple mirred actions, one per desired mirror port, and force the user to stick to the multi-action rule format for subsequent matchall filters. But both DSA and ocelot have the flow_offload_has_one_action() check for the matchall offload, plus the fact that it will get cumbersome to cross-check matchall mirrors with flower mirrors (which will be added in the next patch). As a result, we limit the configuration to a single mirror port, with the possibility of lifting the restriction in the future. Frames injected from the CPU don't get egress-mirrored, since they are sent with the BYPASS bit in the injection frame header, and this bypasses the analyzer module (effectively also the mirroring logic). I don't know what to do/say about this. Functionality was tested with: tc qdisc add dev swp3 clsact tc filter add dev swp3 ingress \ matchall skip_sw \ action mirred egress mirror dev swp1 and pinging through swp3, while seeing that the ICMP replies are mirrored towards swp1.

net: dsa: felix: configure default-prio and dscp priorities
Follow the established programming model for this driver and provide shims in the felix DSA driver which call the implementations from the ocelot switch lib. The ocelot switchdev driver wasn't integrated with dcbnl due to lack of hardware availability. The switch doesn't have any fancy QoS classification enabled by default. The provided getters will create a default-prio app table entry of 0, and no dscp entry. However, the getters have been made to actually retrieve the hardware configuration rather than static values, to be future proof in case DSA will need this information from more call paths. For default-prio, there is a single field per port, in ANA_PORT_QOS_CFG, called QOS_DEFAULT_VAL. DSCP classification is enabled per-port, again via ANA_PORT_QOS_CFG (field QOS_DSCP_ENA), and individual DSCP values are configured as trusted or not through register ANA_DSCP_CFG (replicated 64 times). An untrusted DSCP value falls back to other QoS classification methods. If trusted, the selected ANA_DSCP_CFG register also holds the QoS class in the QOS_DSCP_VAL field. The hardware also supports DSCP remapping (DSCP value X is translated to DSCP value Y before the QoS class is determined based on the app table entry for Y) and DSCP packet rewriting. The dcbnl framework, for being so flexible in other useless areas, doesn't appear to support this. So this functionality has been left out.

net: mscc: ocelot: enforce FDB isolation when VLAN-unaware
Currently ocelot uses a pvid of 0 for standalone ports and ports under a VLAN-unaware bridge, and the pvid of the bridge for ports under a VLAN-aware bridge. Standalone ports do not perform learning, but packets received on them are still subject to FDB lookups. So if the MAC DA that a standalone port receives has been also learned on a VLAN-unaware bridge port, ocelot will attempt to forward to that port, even though it can't, so it will drop packets. So there is a desire to avoid that, and isolate the FDBs of different bridges from one another, and from standalone ports. The ocelot switch library has two distinct entry points: the felix DSA driver and the ocelot switchdev driver. We need to code up a minimal bridge_num allocation in the ocelot switchdev driver too, this is copied from DSA with the exception that ocelot does not care about DSA trees, cross-chip bridging etc. So it only looks at its own ports that are already in the same bridge. The ocelot switchdev driver uses the bridge_num it has allocated itself, while the felix driver uses the bridge_num allocated by DSA. They are both stored inside ocelot_port->bridge_num by the common function ocelot_port_bridge_join() which receives the bridge_num passed by value. Once we have a bridge_num, we can only use it to enforce isolation between VLAN-unaware bridges. As far as I can see, ocelot does not have anything like a FID that further makes VLAN 100 from a port be different to VLAN 100 from another port with regard to FDB lookup. So we simply deny multiple VLAN-aware bridges. For VLAN-unaware bridges, we crop the 4000-4095 VLAN region and we allocate a VLAN for each bridge_num. This will be used as the pvid of each port that is under that VLAN-unaware bridge, for as long as that bridge is VLAN-unaware. VID 0 remains only for standalone ports. It is okay if all standalone ports use the same VID 0, since they perform no address learning, the FDB will contain no entry in VLAN 0, so the packets will always be flooded to the only possible destination, the CPU port. The CPU port module doesn't need to be member of the VLANs to receive packets, but if we use the DSA tag_8021q protocol, those packets are part of the data plane as far as ocelot is concerned, so there it needs to. Just ensure that the DSA tag_8021q CPU port is a member of all reserved VLANs when it is created, and is removed when it is deleted.

net: dsa: felix: support FDB entries on offloaded LAG interfaces
This adds the logic in the Felix DSA driver and Ocelot switch library. For Ocelot switches, the DEST_IDX that is the output of the MAC table lookup is a logical port (equal to physical port, if no LAG is used, or a dynamically allocated number otherwise). The allocation we have in place for LAG IDs is different from DSA's, so we can't use that: - DSA allocates a continuous range of LAG IDs starting from 1 - Ocelot appears to require that physical ports and LAG IDs are in the same space of [0, num_phys_ports), and additionally, ports that aren't in a LAG must have physical port id == logical port id The implication is that an FDB entry towards a LAG might need to be deleted and reinstalled when the LAG ID changes.

net: mscc: ocelot: annotate which traps need PTP timestamping
The ocelot switch library does not need this information, but the felix DSA driver does. As a reminder, the VSC9959 switch in LS1028A doesn't have an IRQ line for packet extraction, so to be notified that a PTP packet needs to be dequeued, it receives that packet also over Ethernet, by setting up a packet trap. The Felix driver needs to install special kinds of traps for packets in need of RX timestamps, such that the packets are replicated both over Ethernet and over the CPU port module. But the Ocelot switch library sets up more than one trap for PTP event messages; it also traps PTP general messages, MRP control messages etc. Those packets don't need PTP timestamps, so there's no reason for the Felix driver to send them to the CPU port module. By knowing which traps need PTP timestamps, the Felix driver can adjust the traps installed using ocelot_trap_add() such that only those will actually get delivered to the CPU port module.

net: mscc: ocelot: keep traps in a list
When using the ocelot-8021q tagging protocol, the CPU port isn't configured as an NPI port, but is a regular port. So a "trap to CPU" operation is actually a "redirect" operation. So DSA needs to set up the trapping action one way or another, depending on the tagging protocol in use. To ease DSA's work of modifying the action, keep all currently installed traps in a list, so that DSA can live-patch them when the tagging protocol changes.

net: mscc: ocelot: avoid overlap in VCAP IS2 between PTP and MRP traps
OCELOT_VCAP_IS2_TAG_8021Q_TXVLAN overlaps with OCELOT_VCAP_IS2_MRP_REDIRECT. To avoid this, make OCELOT_VCAP_IS2_MRP_REDIRECT take the cookie region from N to 2 * N - 1 (where N is ocelot->num_phys_ports). To avoid any risk that the singleton (not per port) VCAP IS2 filters overlap with per-port VCAP IS2 filters, we must ensure that the number of singleton filters is smaller than the number of physical ports. This is true right now, but may change in the future as switches with less ports get supported, or more singleton filters get added. So to be future-proof, let's move the singleton filters at the end of the range, where they won't overlap with anything to their right.

The MRP assist code installs a VCAP IS2 trapping rule for each port, but since the key and the action is the same, just the ingress port mask differs, there isn't any need to do this. We can save some space in the TCAM by using a single filter and adjusting the ingress port mask. Reuse the ocelot_trap_add() and ocelot_trap_del() functions for this purpose. Now that the cookies are no longer per port, we need to change the allocation scheme such that MRP traps use a fixed number.

Networking changes for 5.17.
Core
----
- Defer freeing TCP skbs to the BH handler, whenever possible,
or at least perform the freeing outside of the socket lock section
to decrease cross-CPU allocator work and improve latency.
- Add netdevice refcount tracking to locate sources of netdevice
and net namespace refcount leaks.
- Make Tx watchdog less intrusive - avoid pausing Tx and restarting
all queues from a single CPU removing latency spikes.
- Various small optimizations throughout the stack from Eric Dumazet.
- Make netdev->dev_addr[] constant, force modifications to go via
appropriate helpers to allow us to keep addresses in ordered data
structures.
- Replace unix_table_lock with per-hash locks, improving performance
of bind() calls.
- Extend skb drop tracepoint with a drop reason.
- Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
BPF
---
- New helpers:
- bpf_find_vma(), find and inspect VMAs for profiling use cases
- bpf_loop(), runtime-bounded loop helper trading some execution
time for much faster (if at all converging) verification
- bpf_strncmp(), improve performance, avoid compiler flakiness
- bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt()
for tracing programs, all inlined by the verifier
- Support BPF relocations (CO-RE) in the kernel loader.
- Further the support for BTF_TYPE_TAG annotations.
- Allow access to local storage in sleepable helpers.
- Convert verifier argument types to a composable form with different
attributes which can be shared across types (ro, maybe-null).
- Prepare libbpf for upcoming v1.0 release by cleaning up APIs,
creating new, extensible ones where missing and deprecating those
to be removed.
Protocols
---------
- WiFi (mac80211/cfg80211):
- notify user space about long "come back in N" AP responses,
allow it to react to such temporary rejections
- allow non-standard VHT MCS 10/11 rates
- use coarse time in airtime fairness code to save CPU cycles
- Bluetooth:
- rework of HCI command execution serialization to use a common
queue and work struct, and improve handling errors reported
in the middle of a batch of commands
- rework HCI event handling to use skb_pull_data, avoiding packet
parsing pitfalls
- support AOSP Bluetooth Quality Report
- SMC:
- support net namespaces, following the RDMA model
- improve connection establishment latency by pre-clearing buffers
- introduce TCP ULP for automatic redirection to SMC
- Multi-Path TCP:
- support ioctls: SIOCINQ, OUTQ, and OUTQNSD
- support socket options: IP_TOS, IP_FREEBIND, IP_TRANSPARENT,
IPV6_FREEBIND, and IPV6_TRANSPARENT, TCP_CORK and TCP_NODELAY
- support cmsgs: TCP_INQ
- improvements in the data scheduler (assigning data to subflows)
- support fastclose option (quick shutdown of the full MPTCP
connection, similar to TCP RST in regular TCP)
- MCTP (Management Component Transport) over serial, as defined by
DMTF spec DSP0253 - "MCTP Serial Transport Binding".
Driver API
----------
- Support timestamping on bond interfaces in active/passive mode.
- Introduce generic phylink link mode validation for drivers which
don't have any quirks and where MAC capability bits fully express
what's supported. Allow PCS layer to participate in the validation.
Convert a number of drivers.
- Add support to set/get size of buffers on the Rx rings and size of
the tx copybreak buffer via ethtool.
- Support offloading TC actions as first-class citizens rather than
only as attributes of filters, improve sharing and device resource
utilization.
- WiFi (mac80211/cfg80211):
- support forwarding offload (ndo_fill_forward_path)
- support for background radar detection hardware
- SA Query Procedures offload on the AP side

net: dsa: felix: add port fast age support
Add support for flushing the MAC table on a given port in the ocelot switch library, and use this functionality in the felix DSA driver. This operation is needed when a port leaves a bridge to become standalone, and when the learning is disabled, and when the STP state changes to a state where no FDB entry should be present.

net: ocelot: add FDMA support
Ethernet frames can be extracted or injected autonomously to or from the device’s DDR3/DDR3L memory and/or PCIe memory space. Linked list data structures in memory are used for injecting or extracting Ethernet frames. The FDMA generates interrupts when frame extraction or injection is done and when the linked lists need updating. The FDMA is shared between all the ethernet ports of the switch and uses a linked list of descriptors (DCB) to inject and extract packets. Before adding descriptors, the FDMA channels must be stopped. It would be inefficient to do that each time a descriptor would be added so the channels are restarted only once they stopped. Both channels uses ring-like structure to feed the DCBs to the FDMA. head and tail are never touched by hardware and are completely handled by the driver. On top of that, page recycling has been added and is mostly taken from gianfar driver.

net: mscc: ocelot: create a function that replaces an existing VCAP filter
VCAP (Versatile Content Aware Processor) is the TCAM-based engine behind tc flower offload on ocelot, among other things. The ingress port mask on which VCAP rules match is present as a bit field in the actual key of the rule. This means that it is possible for a rule to be shared among multiple source ports. When the rule is added one by one on each desired port, that the ingress port mask of the key must be edited and rewritten to hardware. But the API in ocelot_vcap.c does not allow for this. For one thing, ocelot_vcap_filter_add() and ocelot_vcap_filter_del() are not symmetric, because ocelot_vcap_filter_add() works with a preallocated and prepopulated filter and programs it to hardware, and ocelot_vcap_filter_del() does both the job of removing the specified filter from hardware, as well as kfreeing it. That is to say, the only option of editing a filter in place, which is to delete it, modify the structure and add it back, does not work because it results in use-after-free. This patch introduces ocelot_vcap_filter_replace, which trivially reprograms a VCAP entry to hardware, at the exact same index at which it existed before, without modifying any list or allocating any memory.

net: dsa: felix: enable cut-through forwarding between ports by default
The VSC9959 switch embedded within NXP LS1028A (and that version of
Ocelot switches only) supports cut-through forwarding - meaning it can
start the process of looking up the destination ports for a packet, and
forward towards those ports, before the entire packet has been received
(as opposed to the store-and-forward mode).
The up side is having lower forwarding latency for large packets. The
down side is that frames with FCS errors are forwarded instead of being
dropped. However, erroneous frames do not result in incorrect updates of
the FDB or incorrect policer updates, since these processes are deferred
inside the switch to the end of frame. Since the switch starts the
cut-through forwarding process after all packet headers (including IP,
if any) have been processed, packets with large headers and small
payload do not see the benefit of lower forwarding latency.
There are two cases that need special attention.
The first is when a packet is multicast (or flooded) to multiple
destinations, one of which doesn't have cut-through forwarding enabled.
The switch deals with this automatically by disabling cut-through
forwarding for the frame towards all destination ports.
The second is when a packet is forwarded from a port of lower link speed
towards a port of higher link speed. This is not handled by the hardware
and needs software intervention.
Since we practically need to update the cut-through forwarding domain
from paths that aren't serialized by the rtnl_mutex (phylink
mac_link_down/mac_link_up ops), this means we need to serialize physical
link events with user space updates of bonding/bridging domains.
Enabling cut-through forwarding is done per {egress port, traffic class}.
I don't see any reason why this would be a configurable option as long
as it works without issues, and there doesn't appear to be any user
space configuration tool to toggle this on/off, so this patch enables
cut-through forwarding on all eligible ports and traffic classes.

net: dsa: felix: restrict psfp rules on ingress port
PSFP rules take effect on the streams from any port of VSC9959 switch. This patch use ingress port to limit the rule only active on this port. Each stream can only match two ingress source ports in VSC9959. Streams from lowest port gets the configuration of SFID pointed by MAC Table lookup and streams from highest port gets the configuration of (SFID+1) pointed by MAC Table lookup. This patch defines the PSFP rule on highest port as dummy rule, which means that it does not modify the MAC table. Signed-off-by: Xiaoliang Yang <xiaoliang.yang_1@nxp.com> Signed-off-by: David S.

VSC9959 supports Per-Stream Filtering and Policing(PSFP) that complies with the IEEE 802.1Qci standard. The stream is identified by Null stream identification(DMAC and VLAN ID) defined in IEEE802.1CB. For PSFP, four tables need to be set up: stream table, stream filter table, stream gate table, and flow meter table. Identify the stream by parsing the tc flower keys and add it to the stream table. The stream filter table is automatically maintained, and its index is determined by SGID(flow gate index) and FMID(flow meter index).

ARM: SoC drivers for 5.16
These are all the driver updates for SoC specific drivers. There
are a couple of subsystems with individual maintainers picking up
their patches here:
- The reset controller subsystem add support for a few new SoC
variants to existing drivers, along with other minor improvements
- The OP-TEE subsystem gets a driver for the ARM FF-A transport
- The memory controller subsystem has improvements for Tegra,
Mediatek, Renesas, Freescale and Broadcom specific drivers.
- The tegra cpuidle driver changes get merged through this
tree this time. There are only minor changes, but they depend
on other tegra driver updates here.
- The ep93xx platform finally moves to using the drivers/clk/
subsystem, moving the code out of arch/arm in the process.
This depends on a small sound driver change that is included
here as well.
- There are some minor updates for Qualcomm and Tegra specific
firmware drivers.
The other driver updates are mainly for drivers/soc, which contains
a mixture of vendor specific drivers that don't really fit elsewhere:
- Mediatek drivers gain more support for MT8192, with new support for
hw-mutex and mmsys routing, plus support for reset lines in the
mmsys driver.
- Qualcomm gains a new "sleep stats" driver, and support for
the "Generic Packet Router" in the APR driver.
- There is a new user interface for routing the UARTS on ASpeed
BMCs, something that apparently nobody else has needed so far.
- More drivers can now be built as loadable modules, in particular
for Broadcom and Samsung platforms.
- Lots of improvements to the TI sysc driver for better suspend/resume
support
Finally, there are lots of minor cleanups and new device IDs for
amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx, layerscape,
allwinner, broadcom, and omap.

net: mscc: ocelot: serialize access to the MAC table
DSA would like to remove the rtnl_lock from its
SWITCHDEV_FDB_{ADD,DEL}_TO_DEVICE handlers, and the felix driver uses
the same MAC table functions as ocelot.
This means that the MAC table functions will no longer be implicitly
serialized with respect to each other by the rtnl_mutex, we need to add
a dedicated lock in ocelot for the non-atomic operations of selecting a

net: mscc: ocelot: allow a config where all bridge VLANs are egress-untagged
At present, the ocelot driver accepts a single egress-untagged bridge
VLAN, meaning that this sequence of operations:
ip link add br0 type bridge vlan_filtering 1
ip link set swp0 master br0
bridge vlan add dev swp0 vid 2 pvid untagged
fails because the bridge automatically installs VID 1 as a pvid & untagged
VLAN, and vid 2 would be the second untagged VLAN on this port. It is
necessary to delete VID 1 before proceeding to add VID 2.
This limitation comes from the fact that we operate the port tag, when
it has an egress-untagged VID, in the OCELOT_PORT_TAG_NATIVE mode.
The ocelot switches do not have full flexibility and can either have one
single VID as egress-untagged, or all of them.
There are use cases for having all VLANs as egress-untagged as well, and
this patch adds support for that.
The change rewrites ocelot_port_set_native_vlan() into a more generic
ocelot_port_manage_port_tag() function. Because the software bridge's
state, transmitted to us via switchdev, can become very complex, we
don't attempt to track all possible state transitions, but instead take
a more declarative approach and just make ocelot_port_manage_port_tag()
figure out which more to operate in:
- port is VLAN-unaware: the classified VLAN (internal, unrelated to the
802.1Q header) is not inserted into packets on egress
- port is VLAN-aware:
- port has tagged VLANs:
-> port has no untagged VLAN: set up as pure trunk
-> port has one untagged VLAN: set up as trunk port + native VLAN
-> port has more than one untagged VLAN: this is an invalid config
which is rejected by ocelot_vlan_prepare
- port has no tagged VLANs
-> set up as pure egress-untagged port
We don't keep the number of tagged and untagged VLANs, we just count the
structures we keep.

net: mscc: ocelot: convert the VLAN masks to a list
First and foremost, the driver currently allocates a constant sized 4K * u32 (16KB memory) array for the VLAN masks. However, a typical application might not need so many VLANs, so if we dynamically allocate the memory as needed, we might actually save some space. Secondly, we'll need to keep more advanced bookkeeping of the VLANs we have, notably we'll have to check how many untagged and how many tagged VLANs we have. This will have to stay in a structure, and allocating another 16 KB array for that is again a bit too much. So refactor the bridge VLANs in a linked list of structures. The hook points inside the driver are ocelot_vlan_member_add() and ocelot_vlan_member_del(), which previously used to operate on the ocelot->vlan_mask[vid] array element. ocelot_vlan_member_add() and ocelot_vlan_member_del() used to call ocelot_vlan_member_set() to commit to the ocelot->vlan_mask. Additionally, we had two calls to ocelot_vlan_member_set() from outside those callers, and those were directly from ocelot_vlan_init(). Those calls do not set up bridging service VLANs, instead they: - clear the VLAN table on reset - set the port pvid to the value used by this driver for VLAN-unaware standalone port operation (VID 0) So now, when we have a structure which represents actual bridge VLANs, VID 0 doesn't belong in that structure, since it is not part of the bridging layer. So delete the middle man, ocelot_vlan_member_set(), and let ocelot_vlan_init() call directly ocelot_vlant_set_mask() which forgoes any data structure and writes directly to hardware, which is all that we need.

In drivers/clocksource/, 3 drivers use "TIMER_CTRL_IE" with 3 different
values. Two of them (mps2-timer.c and timer-sp804.c/timer-sp.h) are
localized and left unmodifed.
One of them uses a shared header file (<soc/arc/timers.h>), which is
what is causing the "redefined" warnings, so change the macro name in
that driver only. Also change the TIMER_CTRL_NH macro name.
Both macro names are prefixed with "ARC_" to reduce the likelihood
of future name collisions.

net: dsa: tag_ocelot_8021q: break circular dependency with ocelot switch lib
Michael reported that when using the "ocelot-8021q" tagging protocol,
the switch driver module must be manually loaded before the tagging
protocol can be loaded/is available.
This appears to be the same problem described here:
https://lore.kernel.org/netdev/20210908220834.d7gmtnwrorhharna@skbuf/
where due to the fact that DSA tagging protocols make use of symbols
exported by the switch drivers, circular dependencies appear and this
breaks module autoloading.
The ocelot_8021q driver needs the ocelot_can_inject() and
ocelot_port_inject_frame() functions from the switch library. Previously
the wrong approach was taken to solve that dependency: shims were
provided for the case where the ocelot switch library was compiled out,
but that turns out to be insufficient, because the dependency when the
switch lib _is_ compiled is problematic too.
We cannot declare ocelot_can_inject() and ocelot_port_inject_frame() as
static inline functions, because these access I/O functions like
__ocelot_write_ix() which is called by ocelot_write_rix(). Making those
static inline basically means exposing the whole guts of the ocelot
switch library, not ideal...
We already have one tagging protocol driver which calls into the switch
driver during xmit but not using any exported symbol: sja1105_defer_xmit.
We can do the same thing here: create a kthread worker and one work item
per skb, and let the switch driver itself do the register accesses to
send the skb, and then consume it.

net: dsa: tag_ocelot: break circular dependency with ocelot switch lib driver
As explained here: https://lore.kernel.org/netdev/20210908220834.d7gmtnwrorhharna@skbuf/ DSA tagging protocol drivers cannot depend on symbols exported by switch drivers, because this creates a circular dependency that breaks module autoloading. The tag_ocelot.c file depends on the ocelot_ptp_rew_op() function exported by the common ocelot switch lib. This function looks at OCELOT_SKB_CB(skb) and computes how to populate the REW_OP field of the DSA tag, for PTP timestamping (the command: one-step/two-step, and the TX timestamp identifier). None of that requires deep insight into the driver, it is quite stateless, as it only depends upon the skb->cb. So let's make it a static inline function and put it in include/linux/dsa/ocelot.h, a file that despite its name is used by the ocelot switch driver for populating the injection header too - since commit |

net: mscc: ocelot: cross-check the sequence id from the timestamp FIFO with the skb PTP header
The sad reality is that when a PTP frame with a TX timestamping request
is transmitted, it isn't guaranteed that it will make it all the way to
the wire (due to congestion inside the switch), and that a timestamp
will be taken by the hardware and placed in the timestamp FIFO where an
IRQ will be raised for it.
The implication is that if enough PTP frames are silently dropped by the
hardware such that the timestamp ID has rolled over, it is possible to
match a timestamp to an old skb.
Furthermore, nobody will match on the real skb corresponding to this
timestamp, since we stupidly matched on a previous one that was stale in
the queue, and stopped there.
So PTP timestamping will be broken and there will be no way to recover.
It looks like the hardware parses the sequenceID from the PTP header,
and also provides that metadata for each timestamp. The driver currently
ignores this, but it shouldn't.
As an extra resiliency measure, do the following:
- check whether the PTP sequenceID also matches between the skb and the
timestamp, treat the skb as stale otherwise and free it
- if we see a stale skb, don't stop there and try to match an skb one
more time, chances are there's one more skb in the queue with the same
timestamp ID, otherwise we wouldn't have ever found the stale one (it
is by timestamp ID that we matched it).
While this does not prevent PTP packet drops, it at least prevents
the catastrophic consequences of incorrect timestamp matching.
Since we already call ptp_classify_raw in the TX path, save the result
in the skb->cb of the clone, and just use that result in the interrupt
code path.

net: mscc: ocelot: avoid overflowing the PTP timestamp FIFO
PTP packets with 2-step TX timestamp requests are matched to packets
based on the egress port number and a 6-bit timestamp identifier.
All PTP timestamps are held in a common FIFO that is 128 entry deep.
This patch ensures that back-to-back timestamping requests cannot exceed
the hardware FIFO capacity. If that happens, simply send the packets
without requesting a TX timestamp to be taken (in the case of felix,
since the DSA API has a void return code in ds->ops->port_txtstamp) or
drop them (in the case of ocelot).
I've moved the ts_id_lock from a per-port basis to a per-switch basis,
because we need separate accounting for both numbers of PTP frames in
flight. And since we need locking to inc/dec the per-switch counter,
that also offers protection for the per-port counter and hence there is
no reason to have a per-port counter anymore.

net: mscc: ocelot: make use of all 63 PTP timestamp identifiers
At present, there is a problem when user space bombards a port with PTP
event frames which have TX timestamping requests (or when a tc-taprio
offload is installed on a port, which delays the TX timestamps by a
significant amount of time). The driver will happily roll over the 2-bit
timestamp ID and this will cause incorrect matches between an skb and
the TX timestamp collected from the FIFO.
The Ocelot switches have a 6-bit PTP timestamp identifier, and the value
63 is reserved, so that leaves identifiers 0-62 to be used.
The timestamp identifiers are selected by the REW_OP packet field, and
are actually shared between CPU-injected frames and frames which match a
VCAP IS2 rule that modifies the REW_OP. The hardware supports
partitioning between the two uses of the REW_OP field through the
PTP_ID_LOW and PTP_ID_HIGH registers, and by default reserves the PTP
IDs 0-3 for CPU-injected traffic and the rest for VCAP IS2.
The driver does not use VCAP IS2 to set REW_OP for 2-step timestamping,
and it also writes 0xffffffff to both PTP_ID_HIGH and PTP_ID_LOW in
ocelot_init_timestamp() which makes all timestamp identifiers available
to CPU injection.
Therefore, we can make use of all 63 timestamp identifiers, which should
allow more timestampable packets to be in flight on each port. This is
only part of the solution, more issues will be addressed in future changes.

net: mscc: ocelot: support egress VLAN rewriting via VCAP ES0
Currently the ocelot driver does support the 'vlan modify' action, but
in the ingress chain, and it is offloaded to VCAP IS1. This action
changes the classified VLAN before the packet enters the bridging
service, and the bridging works with the classified VLAN modified by
VCAP IS1.
That is good for some use cases, but there are others where the VLAN
must be modified at the stage of the egress port, after the packet has
exited the bridging service. One example is simulating IEEE 802.1CB
active stream identification filters ("active" means that not only the
rule matches on a packet flow, but it is also able to change some
headers). For example, a stream is replicated on two egress ports, but
they must have different VLAN IDs on egress ports A and B.
This seems like a task for the VCAP ES0, but that currently only
supports pushing the ES0 tag A, which is specified in the rule. Pushing
another VLAN header is not what we want, but rather overwriting the
existing one.
It looks like when we push the ES0 tag A, it is actually possible to not
only take the ES0 tag A's value from the rule itself (VID_A_VAL), but
derive it from the following formula:
ES0_TAG_A = Classified VID + VID_A_VAL
Otherwise said, ES0_TAG_A can be used to increment with a given value
the VLAN ID that the packet was already classified to, and the packet
will have this value as an outer VLAN tag. This new VLAN ID value then
gets stripped on egress (or not) according to the value of the native
VLAN from the bridging service.
While the hardware will happily increment the classified VLAN ID for all
packets that match the ES0 rule, in practice this would be rather
insane, so we only allow this kind of ES0 action if the ES0 filter
contains a VLAN ID too, so as to restrict the matching on a known
classified VLAN. If we program VID_A_VAL with the delta between the
desired final VLAN (ES0_TAG_A) and the classified VLAN, we obtain the
desired behavior.
It doesn't look like it is possible with the tc-vlan action to modify
the VLAN ID but not the PCP. In hardware it is possible to leave the PCP
to the classified value, but we unconditionally program it to overwrite
it with the PCP value from the rule.

net: mscc: ocelot: fix VCAP filters remaining active after being deleted
When ocelot_flower.c calls ocelot_vcap_filter_add(), the filter has a
given filter->id.cookie. This filter is added to the block->rules list.
However, when ocelot_flower.c calls ocelot_vcap_block_find_filter_by_id()
which passes the cookie as argument, the filter is never found by
filter->id.cookie when searching through the block->rules list.
This is unsurprising, since the filter->id.cookie is an unsigned long,
but the cookie argument provided to ocelot_vcap_block_find_filter_by_id()
is a signed int, and the comparison fails.

ARM: SoC updates for 5.15
There are three noteworthy updates for 32-bit arm platforms this time:
- The Microchip SAMA7 family based on Cortex-A7 gets introduced, a new
cousin to the older SAM9 (ARM9xx based) and SAMA5 (Cortex-A5 based)
SoCs.
- The ixp4xx platform (based on Intel XScale) is finally converted to
device tree, and all the old board files are getting removed now.
- The Cirrus Logic EP93xx platform loses support for the old
MaverickCrunch FPU. Support for compiling user space applications
was already removed in gcc-4.9, and the kernel support for old
applications could not be built with clang ias. After confirming
that there are no remaining users, removing this from the kernel
seemed better than adding support for unused features to clang.
There are minor updates to the aspeed, omap and samsung platforms

net: mscc: ocelot: convert to phylink
The felix DSA driver, which is a wrapper over the same hardware class as
ocelot, is integrated with phylink, but ocelot is using the plain PHY
library. It makes sense to bring together the two implementations, which
is what this patch achieves.
This is a large patch and hard to break up, but it does the following:
The existing ocelot_adjust_link writes some registers, and
felix_phylink_mac_link_up writes some registers, some of them are
common, but both functions write to some registers to which the other
doesn't.
The main reasons for this are:
- Felix switches so far have used an NXP PCS so they had no need to
write the PCS1G registers that ocelot_adjust_link writes
- Felix switches have the MAC fixed at 1G, so some of the MAC speed
changes actually break the link and must be avoided.
The naming conventions for the functions introduced in this patch are:
- vsc7514_phylink_{mac_config,validate} are specific to the Ocelot
instantiations and placed in ocelot_net.c which is built only for the
ocelot switchdev driver.
- ocelot_phylink_mac_link_{up,down} are shared between the ocelot
switchdev driver and the felix DSA driver (they are put in the common
lib).
One by one, the registers written by ocelot_adjust_link are:
DEV_MAC_MODE_CFG - felix_phylink_mac_link_up had no need to write this
register since its out-of-reset value was fine and
did not need changing. The write is moved to the
common ocelot_phylink_mac_link_up and on felix it is
guarded by a quirk bit that makes the written value
identical with the out-of-reset one
DEV_PORT_MISC - runtime invariant, was moved to vsc7514_phylink_mac_config
PCS1G_MODE_CFG - same as above
PCS1G_SD_CFG - same as above
PCS1G_CFG - same as above
PCS1G_ANEG_CFG - same as above
PCS1G_LB_CFG - same as above
DEV_MAC_ENA_CFG - both ocelot_adjust_link and ocelot_port_disable
touched this. felix_phylink_mac_link_{up,down} also
do. We go with what felix does and put it in
ocelot_phylink_mac_link_up.
DEV_CLOCK_CFG - ocelot_adjust_link and felix_phylink_mac_link_up both
write this, but to different values. Move to the common
ocelot_phylink_mac_link_up and make sure via the quirk
that the old values are preserved for both.
ANA_PFC_PFC_CFG - ocelot_adjust_link wrote this, felix_phylink_mac_link_up
did not. Runtime invariant, speed does not matter since
PFC is disabled via the RX_PFC_ENA bits which are cleared.
Move to vsc7514_phylink_mac_config.
QSYS_SWITCH_PORT_MODE_PORT_ENA - both ocelot_adjust_link and
felix_phylink_mac_link_{up,down} wrote
this. Ocelot also wrote this register
from ocelot_port_disable. Keep what
felix did, move in ocelot_phylink_mac_link_{up,down}
and delete ocelot_port_disable.
ANA_POL_FLOWC - same as above
SYS_MAC_FC_CFG - same as above, except slight behavior change. Whereas
ocelot always enabled RX and TX flow control, felix
listened to phylink (for the most part, at least - see
the 2500base-X comment).
The registers which only felix_phylink_mac_link_up wrote are:
SYS_PAUSE_CFG_PAUSE_ENA - this is why I am not sure that flow control
worked on ocelot. Not it should, since the
code is shared with felix where it does.
ANA_PORT_PORT_CFG - this is a Frame Analyzer block register, phylink
should be the one touching them, deleted.
Other changes:
- The old phylib registration code was in mscc_ocelot_init_ports. It is
hard to work with 2 levels of indentation already in, and with hard to
follow teardown logic. The new phylink registration code was moved
inside ocelot_probe_port(), right between alloc_etherdev() and
register_netdev(). It could not be done before (=> outside of)
ocelot_probe_port() because ocelot_probe_port() allocates the struct
ocelot_port which we then use to assign ocelot_port->phy_mode to. It
is more preferable to me to have all PHY handling logic inside the
same function.
- On the same topic: struct ocelot_port_private :: serdes is only used
in ocelot_port_open to set the SERDES protocol to Ethernet. This is
logically a runtime invariant and can be done just once, when the port
registers with phylink. We therefore don't even need to keep the
serdes reference inside struct ocelot_port_private, or to use the devm
variant of of_phy_get().
- Phylink needs a valid phy-mode for phylink_create() to succeed, and
the existing device tree bindings in arch/mips/boot/dts/mscc/ocelot_pcb120.dts
don't define one for the internal PHY ports. So we patch
PHY_INTERFACE_MODE_NA into PHY_INTERFACE_MODE_INTERNAL.
- There was a strategically placed:
switch (priv->phy_mode) {
case PHY_INTERFACE_MODE_NA:
continue;
which made the code skip the serdes initialization for the internal
PHY ports. Frankly that is not all that obvious, so now we explicitly
initialize the serdes under an "if" condition and not rely on code
jumps, so everything is clearer.
- There was a write of OCELOT_SPEED_1000 to DEV_CLOCK_CFG for QSGMII
ports. Since that is in fact the default value for the register field
DEV_CLOCK_CFG_LINK_SPEED, I can only guess the intention was to clear
the adjacent fields, MAC_TX_RST and MAC_RX_RST, aka take the port out
of reset, which does match the comment. I don't even want to know why
this code is placed there, but if there is indeed an issue that all
ports that share a QSGMII lane must all be up, then this logic is
already buggy, since mscc_ocelot_init_ports iterates using
for_each_available_child_of_node, so nobody prevents the user from
putting a 'status = "disabled";' for some QSGMII ports which would
break the driver's assumption.
In any case, in the eventuality that I'm right, we would have yet
another issue if ocelot_phylink_mac_link_down would reset those ports
and that would be forbidden, so since the ocelot_adjust_link logic did
not do that (maybe for a reason), add another quirk to preserve the
old logic.
The ocelot driver teardown goes through all ports in one fell swoop.
When initialization of one port fails, the ocelot->ports[port] pointer
for that is reset to NULL, and teardown is done only for non-NULL ports,
so there is no reason to do partial teardowns, let the central
mscc_ocelot_release_ports() do its job.
Tested bind, unbind, rebind, link up, link down, speed change on mock-up
hardware (modified the driver to probe on Felix VSC9959). Also
regression tested the felix DSA driver. Could not test the Ocelot
specific bits (PCS1G, SERDES, device tree bindings).

net: dsa: felix: stop calling ocelot_port_{enable,disable}
ocelot_port_enable touches ANA_PORT_PORT_CFG, which has the following fields: - LOCKED_PORTMOVE_CPU, LEARNDROP, LEARNCPU, LEARNAUTO, RECV_ENA, all of which are written with their hardware default values, also runtime invariants. So it makes no sense to write these during every .ndo_open. - PORTID_VAL: this field has an out-of-reset value of zero for all ports and must be initialized by software. Additionally, the ocelot_setup_logical_port_ids() code path sets up different logical port IDs for the ports in a hardware LAG, and we absolutely don't want .ndo_open to interfere there and reset those values. So in fact the write from ocelot_port_enable can better be moved to ocelot_init_port, and the .ndo_open hook deleted. ocelot_port_disable touches DEV_MAC_ENA_CFG and QSYS_SWITCH_PORT_MODE_PORT_ENA, in an attempt to undo what ocelot_adjust_link did. But since .ndo_stop does not get called each time the link falls (i.e. this isn't a substitute for .phylink_mac_link_down), felix already does better at this by writing those registers already in felix_phylink_mac_link_down. So keep ocelot_port_disable (for now, until ocelot is converted to phylink too), and just delete the felix call to it, which is not necessary.

ARM: SoC changes for 5.14
A few SoC (code) changes have queued up this cycle, mostly for minor
changes and some refactoring and cleanup of legacy platforms. This
branch also contains a few of the fixes that weren't sent in by the end
of the release (all fairly minor).
- Adding an additional maintainer for the TEE subsystem (Sumit Garg)
- Quite a significant modernization of the IXP4xx platforms by Linus
Walleij, revisiting with a new PCI host driver/binding, removing legacy
mach/* include dependencies and moving platform detection/config to
drivers/soc. Also some updates/cleanup of platform data.
- Core power domain support for Tegra platforms, and some improvements
in build test coverage by adding stubs for compile test targets.
- A handful of updates to i.MX platforms, adding legacy (non-PSCI) SMP
support on i.MX7D, SoC ID setup for i.MX50, removal of platform data
and board fixups for iMX6/7.
... and a few smaller changes and fixes for Samsung, OMAP, Allwinner,
Rockchip.

memory: tegra: Implement SID override programming
Instead of programming all SID overrides during early boot, perform the operation on-demand after the SMMU translations have been set up for a device. This reuses data from device tree to match memory clients for a device and programs the SID specified in device tree, which corresponds to the SID used for the SMMU context banks for the device.

The current per-SoC setup code runs at a fairly arbitrary point during probe, thereby making it less flexible for other SoC generations.

memory: tegra: Introduce struct tegra_mc_ops
Subsequent patches will introduce further callbacks, so create a new struct tegra_mc_ops to collect all of them in a single place. Move the existing ->init() callback into the new structure.

memory: tegra: Unify struct tegra_mc across SoC generations
As another step towards unifying both the Tegra210 (and earlier) and Tegra186 (and later) memory controller drivers, unify the structures that are used to represent them. Note that this comes at a slight space penalty since some fields are not used on all generations, but the benefits of unifying the driver outweigh the downsides.

soc/tegra: pmc: Add driver state syncing
Add driver state syncing that is invoked once all PMC consumers are attached and ready. The consumers are the power domain clients. The synchronization callback is invoked once all client drivers are probed, the driver core handles this for us. This callback informs PMC driver that all voltage votes are initialized by each PD client and it's safe to begin voltage scaling of the core power domain.

Networking changes for 5.13.
Core:
- bpf:
- allow bpf programs calling kernel functions (initially to
reuse TCP congestion control implementations)
- enable task local storage for tracing programs - remove the
need to store per-task state in hash maps, and allow tracing
programs access to task local storage previously added for
BPF_LSM
- add bpf_for_each_map_elem() helper, allowing programs to
walk all map elements in a more robust and easier to verify
fashion
- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
redirection
- lpm: add support for batched ops in LPM trie
- add BTF_KIND_FLOAT support - mostly to allow use of BTF
on s390 which has floats in its headers files
- improve BPF syscall documentation and extend the use of kdoc
parsing scripts we already employ for bpf-helpers
- libbpf, bpftool: support static linking of BPF ELF files
- improve support for encapsulation of L2 packets
- xdp: restructure redirect actions to avoid a runtime lookup,
improving performance by 4-8% in microbenchmarks
- xsk: build skb by page (aka generic zerocopy xmit) - improve
performance of software AF_XDP path by 33% for devices
which don't need headers in the linear skb part (e.g. virtio)
- nexthop: resilient next-hop groups - improve path stability
on next-hops group changes (incl. offload for mlxsw)
- ipv6: segment routing: add support for IPv4 decapsulation
- icmp: add support for RFC 8335 extended PROBE messages
- inet: use bigger hash table for IP ID generation
- tcp: deal better with delayed TX completions - make sure we don't
give up on fast TCP retransmissions only because driver is
slow in reporting that it completed transmitting the original
- tcp: reorder tcp_congestion_ops for better cache locality
- mptcp:
- add sockopt support for common TCP options
- add support for common TCP msg flags
- include multiple address ids in RM_ADDR
- add reset option support for resetting one subflow
- udp: GRO L4 improvements - improve 'forward' / 'frag_list'
co-existence with UDP tunnel GRO, allowing the first to take
place correctly even for encapsulated UDP traffic
- micro-optimize dev_gro_receive() and flow dissection, avoid
retpoline overhead on VLAN and TEB GRO
- use less memory for sysctls, add a new sysctl type, to allow using
u8 instead of "int" and "long" and shrink networking sysctls
- veth: allow GRO without XDP - this allows aggregating UDP
packets before handing them off to routing, bridge, OvS, etc.
- allow specifing ifindex when device is moved to another namespace
- netfilter:
- nft_socket: add support for cgroupsv2
- nftables: add catch-all set element - special element used
to define a default action in case normal lookup missed
- use net_generic infra in many modules to avoid allocating
per-ns memory unnecessarily
- xps: improve the xps handling to avoid potential out-of-bound
accesses and use-after-free when XPS change race with other
re-configuration under traffic
- add a config knob to turn off per-cpu netdev refcnt to catch
underflows in testing
Device APIs:
- add WWAN subsystem to organize the WWAN interfaces better and
hopefully start driving towards more unified and vendor-
-independent APIs
- ethtool:
- add interface for reading IEEE MIB stats (incl. mlx5 and
bnxt support)
- allow network drivers to dump arbitrary SFP EEPROM data,
current offset+length API was a poor fit for modern SFP
which define EEPROM in terms of pages (incl. mlx5 support)
- act_police, flow_offload: add support for packet-per-second
policing (incl. offload for nfp)
- psample: add additional metadata attributes like transit delay
for packets sampled from switch HW (and corresponding egress
and policy-based sampling in the mlxsw driver)

net: mscc: ocelot: support PTP Sync one-step timestamping
Although HWTSTAMP_TX_ONESTEP_SYNC existed in ioctl for hardware timestamp configuration, the PTP Sync one-step timestamping had never been supported. This patch is to truely support it. - ocelot_port_txtstamp_request() This function handles tx timestamp request by storing ptp_cmd(tx timestamp type) in OCELOT_SKB_CB(skb)->ptp_cmd, and additionally for two-step timestamp storing ts_id in OCELOT_SKB_CB(clone)->ptp_cmd. - ocelot_ptp_rew_op() During xmit, this function is called to get rew_op (rewriter option) by checking skb->cb for tx timestamp request, and configure to transmitting. Non-onestep-Sync packet with one-step timestamp request falls back to use two-step timestamp.

net: dsa: free skb->cb usage in core driver
Free skb->cb usage in core driver and let device drivers decide to use or not. The reason having a DSA_SKB_CB(skb)->clone was because dsa_skb_tx_timestamp() which may set the clone pointer was called before p->xmit() which would use the clone if any, and the device driver has no way to initialize the clone pointer. This patch just put memset(skb->cb, 0, sizeof(skb->cb)) at beginning of dsa_slave_xmit(). Some new features in the future, like one-step timestamp may need more bytes of skb->cb to use in dsa_skb_tx_timestamp(), and p->xmit().

net: ocelot: replay switchdev events when joining bridge
The premise of this change is that the switchdev port attributes and objects offloaded by ocelot might have been missed when we are joining an already existing bridge port, such as a bonding interface. The patch pulls these switchdev attributes and objects from the bridge, on behalf of the 'bridge port' net device which might be either the ocelot switch interface, or the bonding upper interface. The ocelot_net.c belongs strictly to the switchdev ocelot driver, while ocelot.c is part of a library shared with the DSA felix driver. The ocelot_port_bridge_leave function (part of the common library) used to call ocelot_port_vlan_filtering(false), something which is not necessary for DSA, since the framework deals with that already there. So we move this function to ocelot_switchdev_unsync, which is specific to the switchdev driver. The code movement described above makes ocelot_port_bridge_leave no longer return an error code, so we change its type from int to void.

net: ocelot: support multiple bridges
The ocelot switches are a bit odd in that they do not have an STP state to put the ports into. Instead, the forwarding configuration is delayed from the typical port_bridge_join into stp_state_set, when the port enters the BR_STATE_FORWARDING state. I can only guess that the implementation of this quirk is the reason that led to the simplification of the driver such that only one bridge could be offloaded at a time. We can simplify the data structures somewhat, and introduce a per-port bridge device pointer and STP state, similar to how the LAG offload works now (there we have a per-port bonding device pointer and TX enabled state). This allows offloading multiple bridges with relative ease, while still keeping in place the quirk to delay the programming of the PGIDs. We actually need this change now because we need to remove the bogus restriction from ocelot_bridge_stp_state_set that ocelot->bridge_mask needs to contain BIT(port), otherwise that function is a no-op.

RISC-V Patches for the 5.12 Merge Window
I have a handful of new RISC-V related patches for this merge window:
* A check to ensure drivers are properly using uaccess. This isn't
manifesting with any of the drivers I'm currently using, but may catch
errors in new drivers.
* Some preliminary support for the FU740, along with the HiFive
Unleashed it will appear on.
* NUMA support for RISC-V, which involves making the arm64 code generic.
* Support for kasan on the vmalloc region.
* A handful of new drivers for the Kendryte K210, along with the DT
plumbing required to boot on a handful of K210-based boards.
* Support for allocating ASIDs.
* Preliminary support for kernels larger than 128MiB.
* Various other improvements to our KASAN support, including the
utilization of huge pages when allocating the KASAN regions.
We may have already found a bug with the KASAN_VMALLOC code, but it's
passing my tests. There's a fix in the works, but that will probably
miss the merge window.

clk: Add RISC-V Canaan Kendryte K210 clock driver
Add a clock provider driver for the Canaan Kendryte K210 RISC-V SoC. This new driver with the compatible string "canaan,k210-clk" implements support for the full clock structure of the K210 SoC. Since it is required for the correct operation of the SoC, this driver is selected by default for compilation when the SOC_CANAAN option is selected. With this change, the k210-sysctl driver is turned into a simple platform driver which enables its power bus clock and triggers populating its child nodes. The sysctl driver retains the SOC early initialization code, but the implementation now relies on the new function k210_clk_early_init() provided by the new clk-k210 driver. The clock structure implemented and many of the coding ideas for the driver come from the work by Sean Anderson on the K210 support for the U-Boot project.

Add basic support for MRP. The HW will just trap all MRP frames on the ring ports to CPU and allow the SW to process them. In this way it is possible to for this node to behave both as MRM and MRC. Current limitations are: - it doesn't support Interconnect roles. - it supports only a single ring. - the HW should be able to do forwarding of MRP Test frames so the SW will not need to do this.

net: dsa: tag_ocelot_8021q: add support for PTP timestamping
For TX timestamping, we use the felix_txtstamp method which is common with the regular (non-8021q) ocelot tagger. This method says that skb deferral is needed, prepares a timestamp request ID, and puts a clone of the skb in a queue waiting for the timestamp IRQ. felix_txtstamp is called by dsa_skb_tx_timestamp() just before the tagger's xmit method. In the tagger xmit, we divert the packets classified by dsa_skb_tx_timestamp() as PTP towards the MMIO-based injection registers, and we declare them as dead towards dsa_slave_xmit. If not PTP, we proceed with normal tag_8021q stuff. Then the timestamp IRQ fires, the clone queued up from felix_txtstamp is matched to the TX timestamp retrieved from the switch's FIFO based on the timestamp request ID, and the clone is delivered to the stack. On RX, thanks to the VCAP IS2 rule that redirects the frames with an EtherType for 1588 towards two destinations: - the CPU port module (for MMIO based extraction) and - if the "no XTR IRQ" workaround is in place, the dsa_8021q CPU port the relevant data path processing starts in the ptp_classify_raw BPF classifier installed by DSA in the RX data path (post tagger, which is completely unaware that it saw a PTP packet). This time we can't reuse the same implementation of .port_rxtstamp that also works with the default ocelot tagger. That is because felix_rxtstamp is given an skb with a freshly stripped DSA header, and it says "I don't need deferral for its RX timestamp, it's right in it, let me show you"; and it just points to the header right behind skb->data, from where it unpacks the timestamp and annotates the skb with it. The same thing cannot happen with tag_ocelot_8021q, because for one thing, the skb did not have an extraction frame header in the first place, but a VLAN tag with no timestamp information. So the code paths in felix_rxtstamp for the regular and 8021q tagger are completely independent. With tag_8021q, the timestamp must come from the packet's duplicate delivered to the CPU port module, but there is potentially complex logic to be handled [ and prone to reordering ] if we were to just start reading packets from the CPU port module, and try to match them to the one we received over Ethernet and which needs an RX timestamp. So we do something simple: we tell DSA "give me some time to think" (we request skb deferral by returning false from .port_rxtstamp) and we just drop the frame we got over Ethernet with no attempt to match it to anything - we just treat it as a notification that there's data to be processed from the CPU port module's queues. Then we proceed to read the packets from those, one by one, which we deliver up the stack, timestamped, using netif_rx - the same function that any driver would use anyway if it needed RX timestamp deferral. So the assumption is that we'll come across the PTP packet that triggered the CPU extraction notification eventually, but we don't know when exactly. Thanks to the VCAP IS2 trap/redirect rule and the exclusion of the CPU port module from the flooding replicators, only PTP frames should be present in the CPU port module's RX queues anyway. There is just one conflict between the VCAP IS2 trapping rule and the semantics of the BPF classifier. Namely, ptp_classify_raw() deems general messages as non-timestampable, but still, those are trapped to the CPU port module since they have an EtherType of ETH_P_1588. So, if the "no XTR IRQ" workaround is in place, we need to run another BPF classifier on the frames extracted over MMIO, to avoid duplicates being sent to the stack (once over Ethernet, once over MMIO). It doesn't look like it's possible to install VCAP IS2 rules based on keys extracted from the 1588 frame headers.

net: mscc: ocelot: refactor ocelot_xtr_irq_handler into ocelot_xtr_poll
Since the felix DSA driver will need to poll the CPU port module for extracted frames as well, let's create some common functions that read an Extraction Frame Header, and then an skb, from a CPU extraction group. We abuse the struct ocelot_ops :: port_to_netdev function a little bit, in order to retrieve the DSA port net_device or the ocelot switchdev net_device based on the source port information from the Extraction Frame Header, but it's all in the benefit of code simplification - netdev_alloc_skb needs it. Originally, the port_to_netdev method was intended for parsing act->dev from tc flower offload code.

net: mscc: ocelot: use common tag parsing code with DSA
The Injection Frame Header and Extraction Frame Header that the switch prepends to frames over the NPI port is also prepended to frames delivered over the CPU port module's queues. Let's unify the handling of the frame headers by making the ocelot driver call some helpers exported by the DSA tagger. Among other things, this allows us to get rid of the strange cpu_to_be32 when transmitting the Injection Frame Header on ocelot, since the packing API uses network byte order natively (when "quirks" is 0). The comments above ocelot_gen_ifh talk about setting pop_cnt to 3, and the cpu extraction queue mask to something, but the code doesn't do it, so we don't do it either.

net: mscc: ocelot: offload bridge port flags to device
We should not be unconditionally enabling address learning, since doing that is actively detrimential when a port is standalone and not offloading a bridge. Namely, if a port in the switch is standalone and others are offloading the bridge, then we could enter a situation where we learn an address towards the standalone port, but the bridged ports could not forward the packet there, because the CPU is the only path between the standalone and the bridged ports. The solution of course is to not enable address learning unless the bridge asks for it. We need to set up the initial port flags for no learning and flooding everything, and also when the port joins and leaves the bridge. The flood configuration was already configured ok for standalone mode in ocelot_init, we just need to disable learning in ocelot_init_port.

net: dsa: felix: implement port flushing on .phylink_mac_link_down
There are several issues which may be seen when the link goes down while
forwarding traffic, all of which can be attributed to the fact that the
port flushing procedure from the reference manual was not closely
followed.
With flow control enabled on both the ingress port and the egress port,
it may happen when a link goes down that Ethernet packets are in flight.
In flow control mode, frames are held back and not dropped. When there
is enough traffic in flight (example: iperf3 TCP), then the ingress port
might enter congestion and never exit that state. This is a problem,
because it is the egress port's link that went down, and that has caused
the inability of the ingress port to send packets to any other port.
This is solved by flushing the egress port's queues when it goes down.
There is also a problem when performing stream splitting for
IEEE 802.1CB traffic (not yet upstream, but a sort of multicast,
basically). There, if one port from the destination ports mask goes
down, splitting the stream towards the other destinations will no longer
be performed. This can be traced down to this line:
ocelot_port_writel(ocelot_port, 0, DEV_MAC_ENA_CFG);
which should have been instead, as per the reference manual:
ocelot_port_rmwl(ocelot_port, 0, DEV_MAC_ENA_CFG_RX_ENA,
DEV_MAC_ENA_CFG);
Basically only DEV_MAC_ENA_CFG_RX_ENA should be disabled, but not
DEV_MAC_ENA_CFG_TX_ENA - I don't have further insight into why that is
the case, but apparently multicasting to several ports will cause issues
if at least one of them doesn't have DEV_MAC_ENA_CFG_TX_ENA set.
I am not sure what the state of the Ocelot VSC7514 driver is, but
probably not as bad as Felix/Seville, since VSC7514 uses phylib and has
the following in ocelot_adjust_link:
if (!phydev->link)
return;
therefore the port is not really put down when the link is lost, unlike
the DSA drivers which use .phylink_mac_link_down for that.
Nonetheless, I put ocelot_port_flush() in the common ocelot.c because it
needs to access some registers from drivers/net/ethernet/mscc/ocelot_rew.h
which are not exported in include/soc/mscc/ and a bugfix patch should
probably not move headers around.
Fixes:

net: mscc: ocelot: rebalance LAGs on link up/down events
At present there is an issue when ocelot is offloading a bonding interface, but one of the links of the physical ports goes down. Traffic keeps being hashed towards that destination, and of course gets dropped on egress. Monitor the netdev notifier events emitted by the bonding driver for changes in the physical state of lower interfaces, to determine which ports are active and which ones are no longer. Then extend ocelot_get_bond_mask to return either the configured bonding interfaces, or the active ones, depending on a boolean argument. The code that does rebalancing only needs to do so among the active ports, whereas the bridge forwarding mask and the logical port IDs still need to look at the permanently bonded ports.

net: mscc: ocelot: drop the use of the "lags" array
We can now simplify the implementation by always using ocelot_get_bond_mask to look up the other ports that are offloading the same bonding interface as us. In ocelot_set_aggr_pgids, the code had a way to uniquely iterate through LAGs. We need to achieve the same behavior by marking each LAG as visited, which we do now by using a temporary 32-bit "visited" bitmask. This is ok and we do not need dynamic memory allocation, because we know that this switch architecture will not have more than 32 ports (the PGID port masks are 32-bit anyway).

net: mscc: ocelot: set up the bonding mask in a way that avoids a net_device
Since this code should be called from pure switchdev as well as from DSA, we must find a way to determine the bonding mask not by looking directly at the net_device lowers of the bonding interface, since those could have different private structures. We keep a pointer to the bonding upper interface, if present, in struct ocelot_port. Then the bonding mask becomes the bitwise OR of all ports that have the same bonding upper interface. This adds a duplication of functionality with the current "lags" array, but the duplication will be short-lived, since further patches will remove the latter completely.

iommu/mediatek: Support master use iova over 32bit
After extending v7s, our pagetable already support iova reach 16GB(34bit). the master got the iova via dma_alloc_attrs may reach 34bits, but its HW register still is 32bit. then how to set the bit32/bit33 iova? this depend on a SMI larb setting(bank_sel). we separate whole 16GB iova to four banks: bank: 0: 0~4G; 1: 4~8G; 2: 8-12G; 3: 12-16G; The bank number is (iova >> 32). We will preassign which bank the larbs belong to. currently we don't have a interface for master to adjust its bank number. Each a bank is a iova_region which is a independent iommu-domain. the iova range for each iommu-domain can't cross 4G.

net: dsa: felix: perform switch setup for tag_8021q
Unlike sja1105, the only other user of the software-defined tag_8021q.c
tagger format, the implementation we choose for the Felix DSA switch
driver preserves full functionality under a vlan_filtering bridge
(i.e. IP termination works through the DSA user ports under all
circumstances).
The tag_8021q protocol just wants:
- Identifying the ingress switch port based on the RX VLAN ID, as seen
by the CPU. We achieve this by using the TCAM engines (which are also
used for tc-flower offload) to push the RX VLAN as a second, outer
tag, on egress towards the CPU port.
- Steering traffic injected into the switch from the network stack
towards the correct front port based on the TX VLAN, and consuming
(popping) that header on the switch's egress.
A tc-flower pseudocode of the static configuration done by the driver
would look like this:
$ tc qdisc add dev <cpu-port> clsact
$ for eth in swp0 swp1 swp2 swp3; do \
tc filter add dev <cpu-port> egress flower indev ${eth} \
action vlan push id <rxvlan> protocol 802.1ad; \
tc filter add dev <cpu-port> ingress protocol 802.1Q flower
vlan_id <txvlan> action vlan pop \
action mirred egress redirect dev ${eth}; \
done
but of course since DSA does not register network interfaces for the CPU
port, this configuration would be impossible for the user to do. Also,
due to the same reason, it is impossible for the user to inadvertently
delete these rules using tc. These rules do not collide in any way with
tc-flower, they just consume some TCAM space, which is something we can
live with.

net: mscc: ocelot: don't use NPI tag prefix for the CPU port module
Context: Ocelot switches put the injection/extraction frame header in
front of the Ethernet header. When used in NPI mode, a DSA master would
see junk instead of the destination MAC address, and it would most
likely drop the packets. So the Ocelot frame header can have an optional
prefix, which is just "ff:ff:ff:ff:ff:fe > ff:ff:ff:ff:ff:ff" padding
put before the actual tag (still before the real Ethernet header) such
that the DSA master thinks it's looking at a broadcast frame with a
strange EtherType.
Unfortunately, a lesson learned in commit

net: mscc: ocelot: store a namespaced VCAP filter ID
We will be adding some private VCAP filters that should not interfere in any way with the filters added using tc-flower. So we need to allocate some IDs which will not be used by tc. Currently ocelot uses an u32 id derived from the flow cookie, which in itself is an unsigned long. This is a problem in itself, since on 64 bit systems, sizeof(unsigned long)=8, so the driver is already truncating these. Create a struct ocelot_vcap_id which contains the full unsigned long cookie from tc, as well as a boolean that is supposed to namespace the filters added by tc with the ones that aren't.

net: mscc: ocelot: configure watermarks using devlink-sb
Using devlink-sb, we can configure 12/16 (the important 75%) of the
switch's controlling watermarks for congestion drops, and we can monitor
50% of the watermark occupancies (we can monitor the reservation
watermarks, but not the sharing watermarks, which are exposed as pool
sizes).
The following definitions can be made:
SB_BUF=0 # The devlink-sb for frame buffers
SB_REF=1 # The devlink-sb for frame references
POOL_ING=0 # The pool for ingress traffic. Both devlink-sb instances
# have one of these.
POOL_EGR=1 # The pool for egress traffic. Both devlink-sb instances
# have one of these.
Editing the hardware watermarks is done in the following way:
BUF_xxxx_I is accessed when sb=$SB_BUF and pool=$POOL_ING
REF_xxxx_I is accessed when sb=$SB_REF and pool=$POOL_ING
BUF_xxxx_E is accessed when sb=$SB_BUF and pool=$POOL_EGR
REF_xxxx_E is accessed when sb=$SB_REF and pool=$POOL_EGR
Configuring the sharing watermarks for COL_SHR(dp=0) is done implicitly
by modifying the corresponding pool size. By default, the pool size has
maximum size, so this can be skipped.
devlink sb pool set pci/0000:00:00.5 sb $SB_BUF pool $POOL_ING \
size 129840 thtype static
Since by default there is no buffer reservation, the above command has
maxed out BUF_COL_SHR_I(dp=0).
Configuring the per-port reservation watermark (P_RSRV) is done in the
following way:
devlink sb port pool set pci/0000:00:00.5/0 sb $SB_BUF \
pool $POOL_ING th 1000
The above command sets BUF_P_RSRV_I(port 0) to 1000 bytes. After this
command, the sharing watermarks are internally reconfigured with 1000
bytes less, i.e. from 129840 bytes to 128840 bytes.
Configuring the per-port-tc reservation watermarks (Q_RSRV) is done in
the following way:
for tc in {0..7}; do
devlink sb tc bind set pci/0000:00:00.5/0 sb 0 tc $tc \
type ingress pool $POOL_ING \
th 3000
done
The above command sets BUF_Q_RSRV_I(port 0, tc 0..7) to 3000 bytes.
The sharing watermarks are again reconfigured with 24000 bytes less.

net: mscc: ocelot: register devlink ports
Add devlink integration into the mscc_ocelot switchdev driver. All physical ports (i.e. the unused ones as well) except the CPU port module at ocelot->num_phys_ports are registered with devlink, and that requires keeping the devlink_port structure outside struct ocelot_port_private, since the latter has a 1:1 mapping with a struct net_device (which does not exist for unused ports). Since we use devlink_port_type_eth_set to link the devlink port to the net_device, we can as well remove the .ndo_get_phys_port_name and .ndo_get_port_parent_id implementations, since devlink takes care of retrieving the port name and number automatically, once .ndo_get_devlink_port is implemented. Note that the felix DSA driver is already integrated with devlink by default, since that is a thing that the DSA core takes care of. This is the reason why these devlink stubs were put in ocelot_net.c and not in the common library. It is also the reason why ocelot::devlink is a pointer and not a full structure embedded inside struct ocelot: because the mscc_ocelot driver allocates that by itself (as the container of struct ocelot, in fact), but in the case of felix, it is DSA who allocates the devlink, and felix just propagates the pointer towards struct ocelot.

net: mscc: ocelot: add ops for decoding watermark threshold and occupancy
We'll need to read back the watermark thresholds and occupancy from hardware (for devlink-sb integration), not only to write them as we did so far in ocelot_port_set_maxlen. So introduce 2 new functions in struct ocelot_ops, similar to wm_enc, and implement them for the 3 supported mscc_ocelot switches. Remove the INUSE and MAXUSE unpacking helpers for the QSYS_RES_STAT register, because that doesn't scale with the number of switches that mscc_ocelot supports now. They have different bit widths for the watermarks, and we need function pointers to abstract that difference away.

net: mscc: ocelot: auto-detect packet buffer size and number of frame references
Instead of reading these values from the reference manual and writing them down into the driver, it appears that the hardware gives us the option of detecting them dynamically. The number of frame references corresponds to what the reference manual notes, however it seems that the frame buffers are reported as slightly less than the books would indicate. On VSC9959 (Felix), the books say it should have 128KB of packet buffer, but the registers indicate only 129840 bytes (126.79 KB). Also, the unit of measurement for FREECNT from the documentation of all these devices is incorrect (taken from an older generation). This was confirmed by Younes Leroul from Microchip support. Not having anything better to do with these values at the moment* (this will change soon), let's just print them. *The frame buffer size is, in fact, used to calculate the tail dropping watermarks.

Since the introduction of the switchdev API, port attributes were transmitted to drivers for offloading using a two-step transactional model, with a prepare phase that was supposed to catch all errors, and a commit phase that was supposed to never fail. Some classes of failures can never be avoided, like hardware access, or memory allocation. In the latter case, merely attempting to move the memory allocation to the preparation phase makes it impossible to avoid memory leaks, since commit |

soc: qcom: rpmh: Remove serialization of TCS commands
Requests sent to RPMH can be sent as fire-n-forget or response required, with the latter ensuring the command has been completed by the hardware accelerator. Commands in a request with tcs_cmd::wait set, would ensure that those select commands are sent as response required, even though the actual TCS request may be fire-n-forget. Also, commands with .wait flag were also guaranteed to be complete before the following command in the TCS is sent. This means that the next command of the same request blocked until the current request is completed. This could mean waiting for a voltage to settle or series of NOCs be configured before the next command is sent. But drivers using this feature have never cared about the serialization aspect. By not enforcing the serialization we can allow the hardware to run in parallel improving the performance. Let's clarify the usage of this member in the tcs_cmd structure to mean only completion and not serialization. This should also improve the performance of bus requests where changes could happen in parallel. Also, CPU resume from deep idle may see benefits from certain wake requests.

memory: tegra124-emc: Make driver modular
Add modularization support to the Tegra124 EMC driver, which now can be compiled as a loadable kernel module. Note that EMC clock must be registered at clk-init time, otherwise PLLM will be disabled as unused clock at boot time if EMC driver is compiled as a module. Hence add a prepare/complete callbacks. similarly to what is done for the Tegra20/30 EMC drivers.

ARM: SoC drivers for v5.11
There are a couple of subsystems maintained by other people that
merge their drivers through the SoC tree, those changes include:
- The SCMI firmware framework gains support for sensor notifications
and for controlling voltage domains.
- A large update for the Tegra memory controller driver, integrating
it better with the interconnect framework
- The memory controller subsystem gains support for Mediatek MT8192
- The reset controller framework gains support for sharing pulsed
resets
For Soc specific drivers in drivers/soc, the main changes are
- The Allwinner/sunxi MBUS gets a rework for the way it handles
dma_map_ops and offsets between physical and dma address spaces.
- An errata fix plus some cleanups for Freescale Layerscape SoCs
- A cleanup for renesas drivers regarding MMIO accesses.
- New SoC specific drivers for Mediatek MT8192 and MT8183 power domains
- New SoC specific drivers for Aspeed AST2600 LPC bus control
and SoC identification.
- Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660
and SDX55.
- A rework of the TI AM33xx 'genpd' power domain support to use
information from DT instead of platform data
- Support for TI AM64x SoCs
- Allow building some Amlogic drivers as modules instead of built-in
Finally, there are numerous cleanups and smaller bug fixes for
Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
Renesas, and Xilinx SoCs.
There is a trivial conflict in the cedrus driver, with two branches
adding the same CEDRUS_CAPABILITY_H265_DEC flag, and another trivial
remove/remove conflict in linux/dma-mapping.h.

net: mscc: ocelot: fix dropping of unknown IPv4 multicast on Seville
The current assumption is that the felix DSA driver has flooding knobs per traffic class, while ocelot switchdev has a single flooding knob. This was correct for felix VSC9959 and ocelot VSC7514, but with the introduction of seville VSC9953, we see a switch driven by felix.c which has a single flooding knob. So it is clear that we must do what should have been done from the beginning, which is not to overwrite the configuration done by ocelot.c in felix, but instead to teach the common ocelot library about the differences in our switches, and set up the flooding PGIDs centrally. The effect that the bogus iteration through FELIX_NUM_TC has upon seville is quite dramatic. ANA_FLOODING is located at 0x00b548, and ANA_FLOODING_IPMC is located at 0x00b54c. So the bogus iteration will actually overwrite ANA_FLOODING_IPMC when attempting to write ANA_FLOODING[1]. There is no ANA_FLOODING[1] in sevile, just ANA_FLOODING. And when ANA_FLOODING_IPMC is overwritten with a bogus value, the effect is that ANA_FLOODING_IPMC gets the value of 0x0003CF7D: MC6_DATA = 61, MC6_CTRL = 61, MC4_DATA = 60, MC4_CTRL = 0. Because MC4_CTRL is zero, this means that IPv4 multicast control packets are not flooded, but dropped. An invalid configuration, and this is how the issue was actually spotted.

soc/fsl/qbman: Add an argument to signal if NAPI processing is required.
dpaa_eth_napi_schedule() and caam_qi_napi_schedule() schedule NAPI if
invoked from:
- Hard interrupt context
- Any context which is not serving soft interrupts
Any context which is not serving soft interrupts includes hard interrupts
so the in_irq() check is redundant. caam_qi_napi_schedule() has a comment
about this:
/*
* In case of threaded ISR, for RT kernels in_irq() does not return
* appropriate value, so use in_serving_softirq to distinguish between
* softirq and irq contexts.
*/
if (in_irq() || !in_serving_softirq())
This has nothing to do with RT. Even on a non RT kernel force threaded
interrupts run obviously in thread context and therefore in_irq() returns
false when invoked from the handler.
The extension of the in_irq() check with !in_serving_softirq() was there
when the drivers were added, but in the out of tree FSL BSP the original
condition was in_irq() which got extended due to failures on RT.
The usage of in_xxx() in drivers is phased out and Linus clearly requested
that code which changes behaviour depending on context should either be
separated or the context be conveyed in an argument passed by the caller,
which usually knows the context. Right he is, the above construct is
clearly showing why.
The following callchains have been analyzed to end up in
dpaa_eth_napi_schedule():
qman_p_poll_dqrr()
__poll_portal_fast()
fq->cb.dqrr()
dpaa_eth_napi_schedule()
portal_isr()
__poll_portal_fast()
fq->cb.dqrr()
dpaa_eth_napi_schedule()
Both need to schedule NAPI.
The crypto part has another code path leading up to this:
kill_fq()
empty_retired_fq()
qman_p_poll_dqrr()
__poll_portal_fast()
fq->cb.dqrr()
dpaa_eth_napi_schedule()
kill_fq() is called from task context and ends up scheduling NAPI, but
that's pointless and an unintended side effect of the !in_serving_softirq()
check.
The code path:
caam_qi_poll() -> qman_p_poll_dqrr()
is invoked from NAPI and I *assume* from crypto's NAPI device and not
from qbman's NAPI device. I *guess* it is okay to skip scheduling NAPI
(because this is what happens now) but could be changed if it is wrong
due to `budget' handling.
Add an argument to __poll_portal_fast() which is true if NAPI needs to be
scheduled. This requires propagating the value to the caller including

net: mscc: ocelot: deny changing the native VLAN from the prepare phase
Put the preparation phase of switchdev VLAN objects to some good use, and move the check we already had, for preventing the existence of more than one egress-untagged VLAN per port, to the preparation phase of the addition.

net: mscc: ocelot: add a "valid" boolean to struct ocelot_vlan
Currently we are checking in some places whether the port has a native VLAN on egress or not, by comparing the ocelot_port->vid value with zero. That works, because VID 0 can never be a native VLAN configured by the bridge, but now we want to make similar checks for the pvid. That won't work, because there are cases when we do have the pvid set to 0 (not by the bridge, by ourselves, but still.. it's confusing). And we can't encode a negative value into an u16, so add a bool to the structure. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

net: mscc: ocelot: support L2 multicast entries
There is one main difference in mscc_ocelot between IP multicast and L2 multicast. With IP multicast, destination ports are encoded into the upper bytes of the multicast MAC address. Example: to deliver the address 01:00:5E:11:22:33 to ports 3, 8, and 9, one would need to program the address of 00:03:08:11:22:33 into hardware. Whereas for L2 multicast, the MAC table entry points to a Port Group ID (PGID), and that PGID contains the port mask that the packet will be forwarded to. As to why it is this way, no clue. My guess is that not all port combinations can be supported simultaneously with the limited number of PGIDs, and this was somehow an issue for IP multicast but not for L2 multicast. Anyway. Prior to this change, the raw L2 multicast code was bogus, due to the fact that there wasn't really any way to test it using the bridge code. There were 2 issues: - A multicast PGID was allocated for each MDB entry, but it wasn't in fact programmed to hardware. It was dummy. - In fact we don't want to reserve a multicast PGID for every single MDB entry. That would be odd because we can only have ~60 PGIDs, but thousands of MDB entries. So instead, we want to reserve a multicast PGID for every single port combination for multicast traffic. And since we can have 2 (or more) MDB entries delivered to the same port group (and therefore PGID), we need to reference-count the PGIDs.

networking changes for the 5.10 merge window
Add redirect_neigh() BPF packet redirect helper, allowing to limit stack traversal in common container configs and improving TCP back-pressure. Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain. Expand netlink policy support and improve policy export to user space. (Ge)netlink core performs request validation according to declared policies. Expand the expressiveness of those policies (min/max length and bitmasks). Allow dumping policies for particular commands. This is used for feature discovery by user space (instead of kernel version parsing or trial and error). Support IGMPv3/MLDv2 multicast listener discovery protocols in bridge. Allow more than 255 IPv4 multicast interfaces. Add support for Type of Service (ToS) reflection in SYN/SYN-ACK packets of TCPv6. In Multi-patch TCP (MPTCP) support concurrent transmission of data on multiple subflows in a load balancing scenario. Enhance advertising addresses via the RM_ADDR/ADD_ADDR options. Support SMC-Dv2 version of SMC, which enables multi-subnet deployments. Allow more calls to same peer in RxRPC. Support two new Controller Area Network (CAN) protocols - CAN-FD and ISO 15765-2:2016. Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit kernel problem. Add TC actions for implementing MPLS L2 VPNs. Improve nexthop code - e.g. handle various corner cases when nexthop objects are removed from groups better, skip unnecessary notifications and make it easier to offload nexthops into HW by converting to a blocking notifier. Support adding and consuming TCP header options by BPF programs, opening the doors for easy experimental and deployment-specific TCP option use. Reorganize TCP congestion control (CC) initialization to simplify life of TCP CC implemented in BPF. Add support for shipping BPF programs with the kernel and loading them early on boot via the User Mode Driver mechanism, hence reusing all the user space infra we have. Support sleepable BPF programs, initially targeting LSM and tracing. Add bpf_d_path() helper for returning full path for given 'struct path'. Make bpf_tail_call compatible with bpf-to-bpf calls. Allow BPF programs to call map_update_elem on sockmaps. Add BPF Type Format (BTF) support for type and enum discovery, as well as support for using BTF within the kernel itself (current use is for pretty printing structures). Support listing and getting information about bpf_links via the bpf syscall. Enhance kernel interfaces around NIC firmware update. Allow specifying overwrite mask to control if settings etc. are reset during update; report expected max time operation may take to users; support firmware activation without machine reboot incl. limits of how much impact reset may have (e.g. dropping link or not). Extend ethtool configuration interface to report IEEE-standard counters, to limit the need for per-vendor logic in user space. Adopt or extend devlink use for debug, monitoring, fw update in many drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw, mv88e6xxx, dpaa2-eth). In mlxsw expose critical and emergency SFP module temperature alarms. Refactor port buffer handling to make the defaults more suitable and support setting these values explicitly via the DCBNL interface. Add XDP support for Intel's igb driver. Support offloading TC flower classification and filtering rules to mscc_ocelot switches. Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as fixed interval period pulse generator and one-step timestamping in dpaa-eth. Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3) offload. Add Lynx PHY/PCS MDIO module, and convert various drivers which have this HW to use it. Convert mvpp2 to split PCS. Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as 7-port Mediatek MT7531 IP. Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver, and wcn3680 support in wcn36xx. Improve performance for packets which don't require much offloads on recent Mellanox NICs by 20% by making multiple packets share a descriptor entry. Move chelsio inline crypto drivers (for TLS and IPsec) from the crypto subtree to drivers/net. Move MDIO drivers out of the phy directory. Clean up a lot of W=1 warnings, reportedly the actively developed subsections of networking drivers should now build W=1 warning free. Make sure drivers don't use in_interrupt() to dynamically adapt their code. Convert tasklets to use new tasklet_setup API (sadly this conversion is not yet complete).

net: dsa: propagate switchdev vlan_filtering prepare phase to drivers
A driver may refuse to enable VLAN filtering for any reason beyond what the DSA framework cares about, such as: - having tc-flower rules that rely on the switch being VLAN-aware - the particular switch does not support VLAN, even if the driver does (the DSA framework just checks for the presence of the .port_vlan_add and .port_vlan_del pointers) - simply not supporting this configuration to be toggled at runtime Currently, when a driver rejects a configuration it cannot support, it does this from the commit phase, which triggers various warnings in switchdev. So propagate the prepare phase to drivers, to give them the ability to refuse invalid configurations cleanly and avoid the warnings. Since we need to modify all function prototypes and check for the prepare phase from within the drivers, take that opportunity and move the existing driver restrictions within the prepare phase where that is possible and easy.

The pipeline order for a packet on ingress is: Basic classification -> VCAP IS1 -> VCAP IS2 Furthermore, IS1 is looked up 3 times, and IS2 is looked up twice (each TCAM entry can be configured to match only on the first lookup, or only on the second, or on both etc). Because the TCAMs are completely independent in hardware, and because of the fixed pipeline, we actually have very limited options when it comes to offloading complex rules to them while still maintaining the same semantics with the software data path. This patch maps flow offload rules to ingress TCAMs according to a predefined chain index number. There is going to be a script in selftests that clarifies the usage model. There is also an egress TCAM (VCAP ES0, the Egress Rewriter), which is modeled on top of the default chain 0 of the egress qdisc, because it doesn't have multiple lookups. Suggested-by: Allan W.

net: mscc: ocelot: introduce conversion helpers between port and netdev
Since the mscc_ocelot_switch_lib is common between a pure switchdev and a DSA driver, the procedure of retrieving a net_device for a certain port index differs, as those are registered by their individual front-ends. Up to now that has been dealt with by always passing the port index to the switch library, but now, we're going to need to work with net_device pointers from the tc-flower offload, for things like indev, or mirred. It is not desirable to refactor that, so let's make sure that the flower offload core has the ability to translate between a net_device and a port index properly.

net: mscc: ocelot: automatically detect VCAP constants
The numbers in struct vcap_props are not intuitive to derive, because they are not a straightforward copy-and-paste from the reference manual but instead rely on a fairly detailed level of understanding of the layout of an entry in the TCAM and in the action RAM. For this reason, bugs are very easy to introduce here. Ease the work of hardware porters and read from hardware the constants that were exported for this particular purpose. Note that this implies that struct vcap_props can no longer be const. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net> |

net: mscc: ocelot: generalize existing code for VCAP
In the Ocelot switches there are 3 TCAMs: VCAP ES0, IS1 and IS2, which have the same configuration interface, but different sets of keys and actions. The driver currently only supports VCAP IS2. In preparation of VCAP IS1 and ES0 support, the existing code must be generalized to work with any VCAP. In that direction, we should move the structures that depend upon VCAP instantiation, like vcap_is2_keys and vcap_is2_actions, out of struct ocelot and into struct vcap_props .keys and .actions, a structure that is replicated 3 times, once per VCAP. We'll pass that structure as an argument to each function that does the key and action packing - only the control logic needs to distinguish between ocelot->vcap[VCAP_IS2] or IS1 or ES0. Another change is to make use of the newly introduced ocelot_target_read and ocelot_target_write API, since the 3 VCAPs have the same registers but put at different addresses.

net: mscc: ocelot: introduce a new ocelot_target_{read,write} API
There are some targets (register blocks) in the Ocelot switch that are
instantiated more than once. For example, the VCAP IS1, IS2 and ES0
blocks all share the same register layout for interacting with the cache
for the TCAM and the action RAM.
For the VCAPs, the procedure for servicing them is actually common. We
just need an API specifying which VCAP we are talking to, and we do that
via these raw ocelot_target_read and ocelot_target_write accessors.
In plain ocelot_read, the target is encoded into the register enum
itself:
u16 target = reg >> TARGET_OFFSET;
For the VCAPs, the registers are currently defined like this:
enum ocelot_reg {
[...]
S2_CORE_UPDATE_CTRL = S2 << TARGET_OFFSET,
S2_CORE_MV_CFG,
S2_CACHE_ENTRY_DAT,
S2_CACHE_MASK_DAT,
S2_CACHE_ACTION_DAT,
S2_CACHE_CNT_DAT,
S2_CACHE_TG_DAT,
[...]
};
which is precisely what we want to avoid, because we'd have to duplicate
the same register map for S1 and for S0, and then figure out how to pass
VCAP instance-specific registers to the ocelot_read calls (basically
another lookup table that undoes the effect of shifting with
TARGET_OFFSET).
So for some targets, propose a more raw API, similar to what is
currently done with ocelot_port_readl and ocelot_port_writel. Those
targets can only be accessed with ocelot_target_{read,write} and not
with ocelot_{read,write} after the conversion, which is fine.
The VCAP registers are not actually modified to use this new API as of
this patch. They will be modified in the next one.

net: dsa: tag_ocelot: use a short prefix on both ingress and egress
There are 2 goals that we follow:
- Reduce the header size
- Make the header size equal between RX and TX
The issue that required long prefix on RX was the fact that the ocelot
DSA tag, being put before Ethernet as it is, would overlap with the area
that a DSA master uses for RX filtering (destination MAC address
mainly).
Now that we can ask DSA to put the master in promiscuous mode, in theory
we could remove the prefix altogether and call it a day, but it looks
like we can't. Using no prefix on ingress, some packets (such as ICMP)
would be received, while others (such as PTP) would not be received.
This is because the DSA master we use (enetc) triggers parse errors
("MAC rx frame errors") presumably because it sees Ethernet frames with
a bad length. And indeed, when using no prefix, the EtherType (bytes
12-13 of the frame, bits 96-111) falls over the REW_VAL field from the
extraction header, aka the PTP timestamp.
When turning the short (32-bit) prefix on, the EtherType overlaps with
bits 64-79 of the extraction header, which are a reserved area
transmitted as zero by the switch. The packets are not dropped by the
DSA master with a short prefix. Actually, the frames look like this in
tcpdump (below is a PTP frame, with an extra dsa_8021q tag - dadb 0482 -
added by a downstream sja1105).
89:0c:a9:f2:01:00 > 88:80:00:0a:00:1d, 802.3, length 0: LLC, \
dsap Unknown (0x10) Individual, ssap ProWay NM (0x0e) Response, \
ctrl 0x0004: Information, send seq 2, rcv seq 0, \
Flags [Response], length 78
0x0000: 8880 000a 001d 890c a9f2 0100 0000 100f ................
0x0010: 0400 0000 0180 c200 000e 001f 7b63 0248 ............{c.H
0x0020: dadb 0482 88f7 1202 0036 0000 0000 0000 .........6......
0x0030: 0000 0000 0000 0000 0000 001f 7bff fe63 ............{..c
0x0040: 0248 0001 1f81 0500 0000 0000 0000 0000 .H..............
0x0050: 0000 0000 0000 0000 0000 0000 ............
So the short prefix is our new default: we've shortened our RX frames by
12 octets, increased TX by 4, and headers are now equal between RX and
TX. Note that we still need promiscuous mode for the DSA master to not
drop it.

net: mscc: ocelot: move NPI port configuration to DSA
Remove the ocelot_configure_cpu() function, which was in fact bringing up 2 ports: the CPU port module, which both switchdev and DSA have, and the NPI port, which only DSA has. The (non-Ethernet) CPU port module is at a fixed index in the analyzer, whereas the NPI port is selected through the "ethernet" property in the device tree. Therefore, the function to set up an NPI port is DSA-specific, so we move it there, simplifying the ocelot switch library a little bit.

net: mscc: ocelot: always pass skb clone to ocelot_port_add_txtstamp_skb
Currently, ocelot switchdev passes the skb directly to the function that enqueues it to the list of skb's awaiting a TX timestamp. Whereas the felix DSA driver first clones the skb, then passes the clone to this queue. This matters because in the case of felix, the common IRQ handler, which is ocelot_get_txtstamp(), currently clones the clone, and frees the original clone. This is useless and can be simplified by using skb_complete_tx_timestamp() instead of skb_tstamp_tx().

net: mscc: ocelot: add locking for the port TX timestamp ID
The ocelot_port->ts_id is used to:
(a) populate skb->cb[0] for matching the TX timestamp in the PTP IRQ
with an skb.
(b) populate the REW_OP from the injection header of the ongoing skb.
Only then is ocelot_port->ts_id incremented.
This is a problem because, at least theoretically, another timestampable
skb might use the same ocelot_port->ts_id before that is incremented.
Normally all transmit calls are serialized by the netdev transmit
spinlock, but in this case, ocelot_port_add_txtstamp_skb() is also
called by DSA, which has started declaring the NETIF_F_LLTX feature

net: dsa: felix: create a template for the DSA tags on xmit
With this patch we try to kill 2 birds with 1 stone. First of all, some switches that use tag_ocelot.c don't have the exact same bitfield layout for the DSA tags. The destination ports field is different for Seville VSC9953 for example. So the choices are to either duplicate tag_ocelot.c into a new tag_seville.c (sub-optimal) or somehow take into account a supposed ocelot->dest_ports_offset when packing this field into the DSA injection header (again not ideal). Secondly, tag_ocelot.c already needs to memset a 128-bit area to zero and call some packing() functions of dubious performance in the fastpath. And most of the values it needs to pack are pretty much constant (BYPASS=1, SRC_PORT=CPU, DEST=port index). So it would be good if we could improve that. The proposed solution is to allocate a memory area per port at probe time, initialize that with the statically defined bits as per chip hardware revision, and just perform a simpler memcpy in the fastpath. Other alternatives have been analyzed, such as: - Create a separate tag_seville.c: too much code duplication for just 1 bit field difference. - Create a separate DSA_TAG_PROTO_SEVILLE under tag_ocelot.c, just like tag_brcm.c, which would have a separate .xmit function. Again, too much code duplication for just 1 bit field difference. - Allocate the template from the init function of the tag_ocelot.c module, instead of from the driver: couldn't figure out a method of accessing the correct port template corresponding to the correct tagger in the .xmit function.

net: mscc: ocelot: convert QSYS_SWITCH_PORT_MODE and SYS_PORT_MODE to regfields
Currently Felix and Ocelot share the same bit layout in these per-port registers, but Seville does not. So we need reg_fields for that. Actually since these are per-port registers, we need to also specify the number of ports, and register size per port, and use the regmap API for multiple ports. There's a more subtle point to be made about the other 2 register fields: - QSYS_SWITCH_PORT_MODE_SCH_NEXT_CFG - QSYS_SWITCH_PORT_MODE_INGRESS_DROP_MODE which we are not writing any longer, for 2 reasons: - Using the previous API (ocelot_write_rix), we were only writing 1 for Felix and Ocelot, which was their hardware-default value, and which there wasn't any intention in changing. - In the case of SCH_NEXT_CFG, in fact Seville does not have this register field at all, and therefore, if we want to have common code we would be required to not write to it.

net: mscc: ocelot: convert port registers to regmap
At the moment, there are some minimal register differences between VSC7514 Ocelot and VSC9959 Felix. To be precise, the PCS1G registers are missing from Felix because it was integrated with an NXP PCS. But with VSC9953 Seville (not yet introduced), the register differences are more pronounced. The MAC registers are located at different offsets within the DEV_GMII target. So we need to refactor the driver to keep a regmap even for per-port registers. The callers of the ocelot_port_readl and ocelot_port_writel were kept unchanged, only the implementation is now more generic.

net: mscc: ocelot: generalize the "ACE/ACL" names
Access Control Lists (and their respective Access Control Entries) are specifically entries in the VCAP IS2, the security enforcement block, according to the documentation. Let's rename the structures and functions to something more generic, so that VCAP IS1 structures (which would otherwise have to be called Ingress Classification Entries) can reuse the same code without confusion. Some renaming that was done: struct ocelot_ace_rule -> struct ocelot_vcap_filter struct ocelot_acl_block -> struct ocelot_vcap_block enum ocelot_ace_type -> enum ocelot_vcap_key_type struct ocelot_ace_vlan -> struct ocelot_vcap_key_vlan enum ocelot_ace_action -> enum ocelot_vcap_action struct ocelot_ace_stats -> struct ocelot_vcap_stats enum ocelot_ace_type -> enum ocelot_vcap_key_type struct ocelot_ace_frame_* -> struct ocelot_vcap_key_* No functional change is intended.

ARM/SoC: drivers for v5.7
These are updates to SoC specific drivers that did not have
another subsystem maintainer tree to go through for some
reason:
- Some bus and memory drivers for the MIPS P5600 based
Baikal-T1 SoC that is getting added through the MIPS tree.
- There are new soc_device identification drivers for TI K3,
Qualcomm MSM8939
- New reset controller drivers for NXP i.MX8MP, Renesas
RZ/G1H, and Hisilicon hi6220
- The SCMI firmware interface can now work across ARM SMC/HVC
as a transport.
- Mediatek platforms now use a new driver for their "MMSYS"
hardware block that controls clocks and some other aspects
in behalf of the media and gpu drivers.
- Some Tegra processors have improved power management
support, including getting woken up by the PMIC and cluster
power down during idle.
- A new v4l staging driver for Tegra is added.
- Cleanups and minor bugfixes for TI, NXP, Hisilicon,
Mediatek, and Tegra.

ARM: SoC changes for v5.8
One new platform gets added, the Realtek RTD1195, which is an older Cortex-a7 based relative of the RTD12xx chips that are already supported in arch/arm64. The platform may also be extended to support running 32-bit kernels on those 64-bit chips for memory-constrained machines. In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally released in 2016 as one of the last high-end 32-bit designs. There is ongoing cleanup for the integrator, tegra, imx, and omap2 platforms, with integrator getting very close to the goal of having zero code in arch/arm/, and omap2 moving more of the chip specifics from old board code into device tree files. The Versatile Express platform is made more modular, with built-in drivers now becoming loadable modules. This is part of a greater effort for the Android OS to have a common kernel binary for all platforms and any platform specific code in loadable modules. The PXA platform drops support for Compulab's pxa2xx boards that had rather unusual flash and PCI drivers but no known users remaining. All device drivers specific to those boards can now get removed as well. Across platforms, there is ongoing cleanup, with Geert and Rob revisiting some a lot of Kconfig options.

This contains a large set of cleanups, bug fixes, general improvements and documentation fixes for the RPMH driver. It adds a debugfs mechanism for inspecting Command DB. Socinfo got the "soc_id" attribute defines and definitions for a various variants of MSM8939. RPMH, RPMPD and RPMHPD where made possible to build as modules, but RPMH had to be reverted due to a compilation issue when tracing is enabled. RPMHPD gained power-domains for the SM8250 voltage corners. The SCM driver gained fixes for two build warnings and the SMP2P had an unnecessary error print removed. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAl7DZcEbHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3FEwIQAK1TrENzsRjB23fY4pEW +hN/SkfMjNPsinmyNOHCo03MQzdFIKUl40aNvaHh3foQXaSG4TW12iot9Ul5nsxn /u6dCSzl15FK7pHYj/VQPWTz2WvpANVqsm6G5tf43hBg2TnStbK1AsxgJ6aq47fp QHehMbfeKpF/gltEowv1b+H7xwNFY7eqlQ9O9umYm3hUQh3Bl5mI6PdbkazDdO1j l/vHuQKkZXRdHtD1BxGBfvhPtM4NWDbOPeWWrw8HRFM5muDPgK9mXMRGDcv+fpHq 4I3670xiTWK1Mfz9+FRBMoxLkIWT6zXILg9aNzuZMTOLoNRt3s6VNdne6uf3naND 2Nrcu7t0b+4xWGbdwwpiAFZm8C6l+R1WTCiY4iOJXDychhVvyVwOLzPdZ4i8Pzx9 a4UJDElu8xj2g++oCcjK816IdNwkA46bM7qVz4mkHRUBMkmK9AU7okBA9HQfbP64 MrKPaUljyZuy7zonpJJBBDKLDEFa9a1pI8sehU8p+MUldxYB/4f/iGC3KzyDvv4Q Uzj6AqdP5pjgIxz98YgpOPPl8pwg1c5OgblNLWoHj4yTaqUzT0ZHIRyQO/O/+3Lg HwCrSy+f3+tgzts3DhyVRmOkOXFHfflSdf4rfKtbiq435yB2dz60dt77dJ0jQuBV M9MiF+SE9oASUupPhs47kNte =tkhb -----END PGP SIGNATURE----- Merge tag 'qcom-drivers-for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers Qualcomm driver updates for v5.8 This contains a large set of cleanups, bug fixes, general improvements and documentation fixes for the RPMH driver.
