On MSM8916 devices, the serial number exposed in sysfs is constant and does
not change across individual devices. It's always:
db410c:/sys/devices/soc0$ cat serial_number
2644893864
The firmware used on MSM8916 exposes SOCINFO_VERSION(0, 8), which does not
have support for the serial_num field in the socinfo struct. There is an
existing check to avoid exposing the serial number in that case, but it's
not correct: When checking the item_size returned by SMEM, we need to make
sure the *end* of the serial_num is within bounds, instead of comparing
with the *start* offset. The serial_number currently exposed on MSM8916
devices is just an out of bounds read of whatever comes after the socinfo
struct in SMEM.
Fix this by changing offsetof() to offsetofend(), so that the size of the
field is also taken into account.

The most significant set of changes is the per netns RTNL. The new
behavior is disabled by default, regression risk should be contained.
Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
default value from PTP_1588_CLOCK_KVM, as the first is intended to be
a more reliable replacement for the latter.
Core
----
- Started a very large, in-progress, effort to make the RTNL lock
scope per network-namespace, thus reducing the lock contention
significantly in the containerized use-case, comprising:
- RCU-ified some relevant slices of the FIB control path
- introduce basic per netns locking helpers
- namespacified the IPv4 address hash table
- remove rtnl_register{,_module}() in favour of rtnl_register_many()
- refactor rtnl_{new,del,set}link() moving as much validation as
possible out of RTNL lock
- convert all phonet doit() and dumpit() handlers to RCU
- convert IPv4 addresses manipulation to per-netns RTNL
- convert virtual interface creation to per-netns RTNL
the per-netns lock infra is guarded by the CONFIG_DEBUG_NET_SMALL_RTNL
knob, disabled by default ad interim.
- Introduce NAPI suspension, to efficiently switching between busy
polling (NAPI processing suspended) and normal processing.
- Migrate the IPv4 routing input, output and control path from direct
ToS usage to DSCP macros. This is a work in progress to make ECN
handling consistent and reliable.
- Add drop reasons support to the IPv4 rotue input path, allowing
better introspection in case of packets drop.
- Make FIB seqnum lockless, dropping RTNL protection for read
access.
- Make inet{,v6} addresses hashing less predicable.
- Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
and timestamps
Things we sprinkled into general kernel code
--------------------------------------------
- Add small file operations for debugfs, to reduce the struct ops size.
- Refactoring and optimization for the implementation of page_frag API,
This is a preparatory work to consolidate the page_frag
implementation.
Netfilter
---------
- Optimize set element transactions to reduce memory consumption
- Extended netlink error reporting for attribute parser failure.
- Make legacy xtables configs user selectable, giving users
the option to configure iptables without enabling any other config.
- Address a lot of false-positive RCU issues, pointed by recent
CI improvements.
BPF
---
- Put xsk sockets on a struct diet and add various cleanups. Overall,
this helps to bump performance by 12% for some workloads.
- Extend BPF selftests to increase coverage of XDP features in
combination with BPF cpumap.
- Optimize and homogenize bpf_csum_diff helper for all archs and also
add a batch of new BPF selftests for it.
- Extend netkit with an option to delegate skb->{mark,priority}
scrubbing to its BPF program.
- Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
programs.
Protocols
---------
- Introduces 4-tuple hash for connected udp sockets, speeding-up
significantly connected sockets lookup.
- Add a fastpath for some TCP timers that usually expires after close,
the socket lock contention.
- Add inbound and outbound xfrm state caches to speed up state lookups.
- Avoid sending MPTCP advertisements on stale subflows, reducing
risks on loosing them.
- Make neighbours table flushing more scalable, maintaining per device
neigh lists.
Driver API
----------
- Introduce a unified interface to configure transmission H/W shaping,
and expose it to user-space via generic-netlink.
- Add support for per-NAPI config via netlink. This makes napi
configuration persistent across queues removal and re-creation.
Requires driver updates, currently supported drivers are:
nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.
- Add ethtool support for writing SFP / PHY firmware blocks.
- Track RSS context allocation from ethtool core.
- Implement support for mirroring to DSA CPU port, via TC mirror
offload.
- Consolidate FDB updates notification, to avoid duplicates on
device-specific entries.
- Expose DPLL clock quality level to the user-space.
- Support master-slave PHY config via device tree.
Tests and tooling
-----------------
- forwarding: introduce deferred commands, to simplify
the cleanup phase
Drivers
-------
- Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic,
Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the
IRQs and queues to NAPI IDs, allowing busy polling and better
introspection.
- Ethernet high-speed NICs:
- nVidia/Mellanox:
- mlx5:
- a large refactor to implement support for cross E-Switch
scheduling
- refactor H/W conter management to let it scale better
- H/W GRO cleanups
- Intel (100G, ice)::
- adds support for ethtool reset
- implement support for per TX queue H/W shaping
- AMD/Solarflare:
- implement per device queue stats support
- Broadcom (bnxt):
- improve wildcard l4proto on IPv4/IPv6 ntuple rules
- Marvell Octeon:
- Adds representor support for each Resource Virtualization Unit
(RVU) device.
- Hisilicon:
- adds support for the BMC Gigabit Ethernet
- IBM (EMAC):
- driver cleanup and modernization
- Cisco (VIC):
- raise the queues number limit to 256
- Ethernet virtual:
- Google vNIC:

Pull networking updates from Paolo Abeni:
"The most significant set of changes is the per netns RTNL. The new
behavior is disabled by default, regression risk should be contained.
Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
default value from PTP_1588_CLOCK_KVM, as the first is intended to be
a more reliable replacement for the latter.
Core:
- Started a very large, in-progress, effort to make the RTNL lock
scope per network-namespace, thus reducing the lock contention
significantly in the containerized use-case, comprising:
- RCU-ified some relevant slices of the FIB control path
- introduce basic per netns locking helpers
- namespacified the IPv4 address hash table
- remove rtnl_register{,_module}() in favour of
rtnl_register_many()
- refactor rtnl_{new,del,set}link() moving as much validation as
possible out of RTNL lock
- convert all phonet doit() and dumpit() handlers to RCU
- convert IPv4 addresses manipulation to per-netns RTNL
- convert virtual interface creation to per-netns RTNL
the per-netns lock infrastructure is guarded by the
CONFIG_DEBUG_NET_SMALL_RTNL knob, disabled by default ad interim.
- Introduce NAPI suspension, to efficiently switching between busy
polling (NAPI processing suspended) and normal processing.
- Migrate the IPv4 routing input, output and control path from direct
ToS usage to DSCP macros. This is a work in progress to make ECN
handling consistent and reliable.
- Add drop reasons support to the IPv4 rotue input path, allowing
better introspection in case of packets drop.
- Make FIB seqnum lockless, dropping RTNL protection for read access.
- Make inet{,v6} addresses hashing less predicable.
- Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
and timestamps
Things we sprinkled into general kernel code:
- Add small file operations for debugfs, to reduce the struct ops
size.
- Refactoring and optimization for the implementation of page_frag
API, This is a preparatory work to consolidate the page_frag
implementation.
Netfilter:
- Optimize set element transactions to reduce memory consumption
- Extended netlink error reporting for attribute parser failure.
- Make legacy xtables configs user selectable, giving users the
option to configure iptables without enabling any other config.
- Address a lot of false-positive RCU issues, pointed by recent CI
improvements.
BPF:
- Put xsk sockets on a struct diet and add various cleanups. Overall,
this helps to bump performance by 12% for some workloads.
- Extend BPF selftests to increase coverage of XDP features in
combination with BPF cpumap.
- Optimize and homogenize bpf_csum_diff helper for all archs and also
add a batch of new BPF selftests for it.
- Extend netkit with an option to delegate skb->{mark,priority}
scrubbing to its BPF program.
- Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
programs.
Protocols:
- Introduces 4-tuple hash for connected udp sockets, speeding-up
significantly connected sockets lookup.
- Add a fastpath for some TCP timers that usually expires after
close, the socket lock contention.
- Add inbound and outbound xfrm state caches to speed up state
lookups.
- Avoid sending MPTCP advertisements on stale subflows, reducing
risks on loosing them.
- Make neighbours table flushing more scalable, maintaining per
device neigh lists.
Driver API:
- Introduce a unified interface to configure transmission H/W
shaping, and expose it to user-space via generic-netlink.
- Add support for per-NAPI config via netlink. This makes napi
configuration persistent across queues removal and re-creation.
Requires driver updates, currently supported drivers are:
nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.
- Add ethtool support for writing SFP / PHY firmware blocks.
- Track RSS context allocation from ethtool core.
- Implement support for mirroring to DSA CPU port, via TC mirror
offload.
- Consolidate FDB updates notification, to avoid duplicates on
device-specific entries.
- Expose DPLL clock quality level to the user-space.
- Support master-slave PHY config via device tree.
Tests and tooling:
- forwarding: introduce deferred commands, to simplify the cleanup
phase
Drivers:
- Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic,
Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the
IRQs and queues to NAPI IDs, allowing busy polling and better
introspection.
- Ethernet high-speed NICs:

This release adds the devicetree files for an impressive number of new
SoC variants, though as expected these are all related to others we
already support:
- The microchip sam9x7 devicetree is now added, after the device driver
and platform code has already made it in. This is likely the last ARMv5
(!) platform to ever get added, updating the 20+ year old at91/sam9
platform wtih DDR3 memory and gigabit ethernet.
- On the Apple platform, there are now devicetree files for a number of
A-series SoCs in addition to the M-series ones, these are used
primarily in phones and tablets, but are closely related to the
already supported chips.
- Samsung Exynos 8895 and Exynos 990 are more phone SoCs used in older
Samsung Galaxy phones.
- Qualcomm Snapdragon 778G (SM7325) is another phone SoC, closely related
to the Snapdragon 7c+ Gen 3 (SC7280) used in low-end laptops.
- Rockchip RK3528 and RK3576 are new variants of their TV box and Tablet
chips, still using the older ARMv8.0 cores from RK3328/RK3399 but
with a newer process and other improvements from the RK35xx (otherwise
ARMv8.2) chips. RK3566T and RK3399-S are also added, these are just
lower-cost versions of their normal counterparts.
- TI J742S2 is a feature-reduced version of the J784s4
industrial/automotive SoC, with fewer CPU cores.
- Sophgo SG2002 is an embedded SoC with one RISC-V (C906) and one ARM
(Cortex-A53) core, at this point support is only added for running
on the RISC-V side on the LicheeRV Nano board.
A total of 92 new .dts files describing individual machines is added,
which must be a new record. The majority of these is for the newly added
chips above, notably all the Apple phones and tablets. The other new
machines include nine industrial/embedded boards with NXP i.MX6 or i.MX8
SoCs, eight for Rockchips RK35XX and one or two each for Rockchips RV1109,
RK3308, Allwinner A33, Tegra 234, Qualcomm qcs9100/sc8280xp/x1e80100,
TI AM625 and Starfive JH7110.
As usual there are also many newlyad added features in existing boards
as well as cleanups and minor bugfixes.

- Tree wide:
* Make nr_irqs static to the core code and provide accessor functions
to remove existing and prevent future aliasing problems with local
variables or function arguments of the same name.
- Core code:
* Prevent freeing an interrupt in the devres code which is not managed
by devres in the first place.
* Use seq_put_decimal_ull_width() for decimal values output in
/proc/interrupts which increases performance significantly as it
avoids parsing the format strings over and over.
* Optimize raising the timer and hrtimer soft interrupts by using the
'set bit only' variants instead of the combined version which checks
whether ksoftirqd should be woken up. The latter is a pointless
exercise as both soft interrupts are raised in the context of the
timer interrupt and therefore never wake up ksoftirqd.
* Delegate timer/hrtimer soft interrupt processing to a dedicated thread
on RT.
Timer and hrtimer soft interrupts are always processed in ksoftirqd
on RT enabled kernels. This can lead to high latencies when other
soft interrupts are delegated to ksoftirqd as well.
The separate thread allows to run them seperately under a RT
scheduling policy to reduce the latency overhead.
- Drivers:
* New drivers or extensions of existing drivers to support Renesas
RZ/V2H(P), Aspeed AST27XX, T-HEAD C900 and ATMEL sam9x7 interrupt
chips
* Support for multi-cluster GICs on MIPS.
MIPS CPUs can come with multiple CPU clusters, where each CPU cluster
has its own GIC (Generic Interrupt Controller). This requires to
access the GIC of a remote cluster through a redirect register block.
This is encapsulated into a set of helper functions to keep the
complexity out of the actual code paths which handle the GIC details.
* Support for encrypted guests in the ARM GICV3 ITS driver
The ITS page needs to be shared with the hypervisor and therefore
must be decrypted.
* Small cleanups and fixes all over the place

The non-scoped variant of this macro turns error-prone as soon as error
paths are included, because explicit calls to of_node_put() are required
to avoid leaking memory.
Using its scoped counterpart simplifies the code by removing the need of
explicit calls to of_node_put(), as they are automatically triggered as
soon as the child node goes out of scope. Moreover, it is more robust as
it accounts for new error paths without having to worry about
decrementing the object's refcount.
Note that the device_node is declared within the macro, and its explicit
declaration can be dropped as well if it is not used anywhere else.

store the result of a device_link_add call with the

Commit c14e64b469 ("soc: qcom: llcc: Support chipsets that can write
to llcc") made the code not configure certain registers on SDM845 due
to firmware security policies. That turned out only to concern SDM845,
but the condition was chosen such that all other entries (for SoCs that
didnot need it) were required to set .need_llcc_cfg = true.
Flip the condition, so the default is "doesn't need the workaround".

This adds support for the MT8188 SoC in the MediaTek Regulator
Coupler driver, allowing stable GPU DVFS on this chip;
Moreover, this adds a new MediaTek DVFS Resource Collector (DVFSRC)
driver, allowing to enable other drivers (interconnect, regulator)

MediaTek soc driver updates for v6.13
This adds support for the MT8188 SoC in the MediaTek Regulator
Coupler driver, allowing stable GPU DVFS on this chip;
Moreover, this adds a new MediaTek DVFS Resource Collector (DVFSRC)
driver, allowing to enable other drivers (interconnect, regulator)
which can now communicate with the DVFSRC hardware.
Last but not least, this includes some cleanups for the CMDQ Helper
and MediaTek SVS drivers.

net_dim() is currently passed a struct dim_sample argument by value.
struct dim_sample is 24 bytes. Since this is greater 16 bytes, x86-64
passes it on the stack. All callers have already initialized dim_sample
on the stack, so passing it by value requires pushing a duplicated copy
to the stack. Either witing to the stack and immediately reading it, or
perhaps dereferencing addresses relative to the stack pointer in a chain
of push instructions, seems to perform quite poorly.
In a heavy TCP workload, mlx5e_handle_rx_dim() consumes 3% of CPU time,
94% of which is attributed to the first push instruction to copy
dim_sample on the stack for the call to net_dim():
// Call ktime_get()
0.26 |4ead2: call 4ead7 <mlx5e_handle_rx_dim+0x47>
// Pass the address of struct dim in %rdi
|4ead7: lea 0x3d0(%rbx),%rdi
// Set dim_sample.pkt_ctr
|4eade: mov %r13d,0x8(%rsp)
// Set dim_sample.byte_ctr
|4eae3: mov %r12d,0xc(%rsp)
// Set dim_sample.event_ctr
0.15 |4eae8: mov %bp,0x10(%rsp)
// Duplicate dim_sample on the stack
94.16 |4eaed: push 0x10(%rsp)
2.79 |4eaf1: push 0x10(%rsp)
0.07 |4eaf5: push %rax
// Call net_dim()
0.21 |4eaf6: call 4eafb <mlx5e_handle_rx_dim+0x6b>
To allow the caller to reuse the struct dim_sample already on the stack,
pass the struct dim_sample by reference to net_dim().

After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/soc to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.
On the way do a few whitespace changes to make indention consistent.

As commit cbe16f35be ("genirq: Add IRQF_NO_AUTOEN for request_irq/nmi()")
said, reqeust_irq() and then disable_irq() is unsafe. In the small time gap
between request_irq() and disable_irq(), interrupts can still come.
IRQF_NO_AUTOEN flag can be used by drivers to request_irq(). It prevents
the automatic enabling of the requested interrupt in the same
safe way. With that the usage can be simplified and corrected.
Compile-tested only.

Some versions of the pmic_glink firmware does not allow dynamic GLINK
intent allocations, attempting to send a message before the firmware has
allocated its receive buffers and announced these intent allocations
will fail. When this happens something like this showns up in the log:
pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to send altmode request: 0x10 (-125)
pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to request altmode notifications: -125
ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: failed to send UCSI read request: -125
qcom_battmgr.pmic_glink_power_supply pmic_glink.power-supply.0: failed to request power notifications
GLINK has been updated to distinguish between the cases where the remote
is going down (-ECANCELED) and the intent allocation being rejected
(-EAGAIN).
Retry the send until intent buffers becomes available, or an actual
error occur.
To avoid infinitely waiting for the firmware in the event that this
misbehaves and no intents arrive, an arbitrary 5 second timeout is
used.
This patch was developed with input from Chris Lew.

With driver_async_probe=* on kernel command line, the following trace is
produced because on i.MX8M Plus hardware because the soc-imx8m.c driver
calls of_clk_get_by_name() which returns -EPROBE_DEFER because the clock
driver is not yet probed. This was not detected during regular testing
without driver_async_probe.
Convert the SoC code to platform driver and instantiate a platform device
in its current device_initcall() to probe the platform driver. Rework
.soc_revision callback to always return valid error code and return SoC
revision via parameter. This way, if anything in the .soc_revision callback
return -EPROBE_DEFER, it gets propagated to .probe and the .probe will get
retried later.

IS_ERR_VALUE() is only meant for pointers. Fix this by checking for a
negative error value instead, which matches the documented behavior of
devm_qe_muram_alloc() aka devm_cpm_muram_alloc().
While at it, remove the unneeded print in case of a memory allocation
failure, and propagate the returned error code.

The driver updates seem larger this time around, with changes
is many of the SoC specific drivers, both the custom drivers/soc
ones and the closely related subsystems (memory, bus, firmware,
reset, ...).
The at91 platform gains support for sam9x7 chips in the soc and
power management code. This is the latest variant of one of the
oldest still supported SoC families, using the ARM9 (ARMv5) core.
As usual, the qualcomm snapdragon platform gets a ton of updates in many
of their drivers to add more features and additional SoC support. Most
of these are somewhat firmware related as the platform has a number of
firmware based interfaces to the kernel. A notable addition here is the
inclusion of trace events to two of these drivers.
Herve Codina and Christophe Leroy are now sending updates for
drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC
and Arm specific platforms and has previously been problematic to
maintain. The first update here contains support for newer PowerPC
variants and some cleanups.
The turris mox firmware driver has a number of updates, mostly cleanups.
The Arm SCMI firmware driver gets a major rework to modularize
the existing code into separately loadable drivers for the various
transports, the addition of custom NXP i.MX9 interfaces and a
number of smaller updates.
The Arm FF-A firmware driver gets a feature update to support
the v1.2 version of the specification.
The reset controller drivers have some smaller cleanups and a newly
added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs.
The memory controller drivers get some cleanups and refactoring
for Tegra, TI, Freescale/NXP and a couple more platforms.
Finally there are lots of minor updates to firmware (raspberry pi,
tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra, amlogic,
mediatek) drivers and their DT bindings.

QMC driver requires fsl_soc.h to use function get_immrbase().
This header is provided by powerpc architecture and the functions
it declares are defined only when FSL_SOC is selected.
Today the dependency is the following:
depends on CPM1 || QUICC_ENGINE || \
(FSL_SOC && (CPM || QUICC_ENGINE) && COMPILE_TEST)
This dependency tentatively ensure that FSL_SOC is there when doing a
COMPILE_TEST.
CPM1 is only selected by PPC_8xx and cannot be selected manually.
CPM1 selects FSL_SOC
QUICC_ENGINE on the other hand can be selected by ARM or ARM64 which
doesn't select FSL_SOC. QUICC_ENGINE can also be selected with just
COMPILE_TEST.
It is therefore possible to end up with CPM_QMC selected
without FSL_SOC.
So fix it by making it depend on FSL_SOC at all time.
The rest of the above dependency is the same as the one for CPM_TSA on
which CPM_QMC also depends, so it can go away, leaving only a simple
dependency on FSL_SOC.

================
This series add support for the QUICC Engine (QE) version of TSA and QMC
components.
CPM1 version is already supported and, as the QE version of those
component are pretty similar to the CPM1 version, the series extend
the already existing drivers to support for the QE version.
The TSA and QMC components are tightly coupled and so the series
provides modifications on both components.
Of course, this series can be split if it is needed. Let me know.
The series is composed of:
- Patches 1 and 2: Fixes related to TRNSYNC in the QMC driver
- Patches 3..6: Fixes of checkpatch detected issues in the TSA driver
- Patch 7: The QE TSA device-tree binding
- Patches 8..13: TSA driver preparations for adding support for QE
- Patches 14 and 15: The support for QE in TSA + MAINTAINERS update
- Patch 16: A TSA API improvement needed for the QE QMC driver
- Patch 17: A clarification in the QE QMC driver
- Patches 18..22: Fixes of checkpatch detected issues in the QMC driver
- Patch 23: The QE QMC device-tree binding
- Patches 24..31: QMC driver preparations for adding support for QE
- Patches 32 and 33: Missing features additions in QE code
- Patches 34..36: The QMC support for QE in QMC + MAINTAINERS update
Compared to the previous iteration, this v2 series updates device-tree
bindings and fixes issues detected by kernel test robots.
Related to the QE QMC device-tree binding, I kept the unit address in
decimal and the 3 compatible strings.

This warning was added by commit 07f86917a4 ("soc/fsl/qbman: Use
shared-dma-pool for QMan private memory allocations") but
RESERVEDMEM_OF_DECLARE usage was removed by
commit 3e62273ac6 ("soc: fsl: qbman: Remove RESERVEDMEM_OF_DECLARE
usage") . For non-popwerpc platforms, such as ls1043, this warning
is redundant. ls1043 itself uses shared-dma-mem.

Add support for the QMC (QUICC Multichannel Controller) available in
some PowerQUICC SoC that uses a QUICC Engine (QE) block such as MPC8321.
This QE QMC is similar to the CPM QMC except that it uses UCCs (Unified
Communication Controllers) instead of SCCs (Serial Communication
Controllers). Also, compared against the CPM QMC, this QE QMC does not
use a fixed area for the UCC/SCC parameters area but it uses a dynamic
area allocated and provided to the hardware at runtime.

Current code handles CPM1 version of QMC. In the QUICC Engine (QE)
version, some operations done at probe() need to be done in a different
order.
In order to prepare the support for the QE version, changed the sequence
of operation done at probe():
- Retrieve the tsa_serial earlier, before initializing resources.
- Group SCC initialisation and do this initialization when it is really
needed in the probe() sequence.
Having the QE compatible sequence in the CPM1 version does not lead to
any issue and works correctly without any regressions.

This corrects the tzmem virt-to-phys conversion, which caused issues for
the uefisecapp implementation of EFI variable access. SDM670 is excluded
from tzmem usage due to reported issues.
The SCM get wait queue context call is corrected to be marked ATOMIC and
some dead code in qseecom, following the tzmem conversion, is removed.
The memory backing command DB is remapped writecombined, to avoid XPU
violations when Linux runs without the Qualcomm hypervisor.
Two compile fixes are added for pd-mapper, and the broken reference
count is corrected, to make pd-mapper deal with remoteprocs going away.
In pmic_glink a race condition where the client callbacks might be
called before we returned the client handle is corrected. The broken conditions
for when to signal that the firmware is going down is also corrected.
In the pmic_glink UCSI driver, the ucsi_unregister() is moved out of the
pdr callback, as this is being invoked in atomic context.
Konrad's email address is updated in MAINTAINERS, and related mailmap
entries are added.

Qualcomm driver fixes for v6.11
This corrects the tzmem virt-to-phys conversion, which caused issues for
the uefisecapp implementation of EFI variable access. SDM670 is excluded
from tzmem usage due to reported issues.
The SCM get wait queue context call is corrected to be marked ATOMIC and
some dead code in qseecom, following the tzmem conversion, is removed.
The memory backing command DB is remapped writecombined, to avoid XPU
violations when Linux runs without the Qualcomm hypervisor.
Two compile fixes are added for pd-mapper, and the broken reference
count is corrected, to make pd-mapper deal with remoteprocs going away.
In pmic_glink a race condition where the client callbacks might be
called before we returned the client handle is corrected. The broken conditions
for when to signal that the firmware is going down is also corrected.
In the pmic_glink UCSI driver, the ucsi_unregister() is moved out of the
pdr callback, as this is being invoked in atomic context.
Konrad's email address is updated in MAINTAINERS, and related mailmap
entries are added.

Use scope based cleanup, instead of manual of_node_put() calls, which
automatically free()s "struct device_node".
While at it, refactor the code from knav_queue_probe() into the separate
functions to make auto cleanup look more neat.
Doing the cleanup this way has the advantage of reducing the chance of
memory leaks in case we need to read from new OF nodes in the future
when we probe.

Factor out memories setup code from probe() into a new function
pruss_of_setup_memories(). This sets the stage for introducing auto
cleanup of the device node (done in the subsequent patch), since the
clean up depends on the scope of the pointer and factoring out
code into a separate function obviously limits the scope of the various
variables used in that function.
Apart from the above, this change also has the advantage of making the
code look more neat.
While at it, use dev_err_probe() instead of plain dev_err() as this new
function is called by the probe().

RK3128 has a setting in GRF which selects whether the vpu attached iommu
uses the AXI clock of the decoder (vdpu) or the encoder (vepu). The
default is vepu but some part of the vendor firmware sets it to vdpu.
In order to be independent on whether any of those vendor firmware blobs is
used to boot the SoC reset "vpu main clock" setting to it's default value.

The Qualcomm pd-mapper is a refcounted singleton, but the refcount is
never incremented, which means the as soon as any remoteproc instance
stops the count will hit 0.
At this point the pd-mapper QMI service is stopped, leaving firmware
without access to the PD information. Stopping any other remoteproc
instances will result in a use-after-free, which best case manifest
itself as a refcount underflow:
refcount_t: underflow; use-after-free.
WARNING: CPU: 1 PID: 354 at lib/refcount.c:87 refcount_dec_and_mutex_lock+0xc4/0x148

Fix this by incrementing the refcount, so that the pd-mapper is only
torn down when the last remoteproc stops, as intended.

When the pmic_glink state is UP and we either receive a protection-
domain (PD) notification indicating that the PD is going down, or that
the whole remoteproc is going down, it's expected that the pmic_glink
client instances are notified that their function has gone DOWN.
This is not what the code does, which results in the client state either
not updating, or being wrong in many cases. So let's fix the conditions.

Commit '9329933699b3 ("soc: qcom: pmic_glink: Make client-lock
non-sleeping")' moved the pmic_glink client list under a spinlock, as it
is accessed by the rpmsg/glink callback, which in turn is invoked from
IRQ context.
This means that ucsi_unregister() is now called from atomic context,
which isn't feasible as it's expecting a sleepable context. An effort is
under way to get GLINK to invoke its callbacks in a sleepable context,
but until then lets schedule the unregistration.
A side effect of this is that ucsi_unregister() can now happen
after the remote processor, and thereby the communication link with it, is
gone. pmic_glink_send() is amended with a check to avoid the resulting NULL
pointer dereference.
This does however result in the user being informed about this error by
the following entry in the kernel log:
ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: failed to send UCSI write request: -5

As pointed out by Stephen Boyd it is possible that during initialization
of the pmic_glink child drivers, the protection-domain notifiers fires,
and the associated work is scheduled, before the client registration
returns and as a result the local "client" pointer has been initialized.
The outcome of this is a NULL pointer dereference as the "client"
pointer is blindly dereferenced.
Timeline provided by Stephen:
CPU0 CPU1
---- ----
ucsi->client = NULL;
devm_pmic_glink_register_client()
client->pdr_notify(client->priv, pg->client_state)
pmic_glink_ucsi_pdr_notify()
schedule_work(&ucsi->register_work)
<schedule away>
pmic_glink_ucsi_register()
ucsi_register()
pmic_glink_ucsi_read_version()
pmic_glink_ucsi_read()
pmic_glink_ucsi_read()
pmic_glink_send(ucsi->client)
<client is NULL BAD>
ucsi->client = client // Too late!
This code is identical across the altmode, battery manager and usci
child drivers.
Resolve this by splitting the allocation of the "client" object and the
registration thereof into two operations.
This only happens if the protection domain registry is populated at the
time of registration, which by the introduction of commit '1ebcde047c54
("soc: qcom: add pd-mapper implementation")' became much more likely.

All of mutex_mod and mutex_table_mod contain an array of bit
numbers, which can go from 0 to 63, it is hence not needed to
use an unsigned 32-bits integer to store that: change them to
unsigned 8-bits instead.
As for the mutex_sof table since this directly contains the values
to write to the DISP_MUTEXn_CTL register, which has only bits [13:0]
(so this register is effectively 14 bits long), change that to use
unsigned 16-bits.
The type of mutex_{mod,sof}_reg was also changed to 16 bits, as
the maximum value that those will ever have is 0x800, because it
calculates as 0x30 + (0x20 * n) where n's maximum value is 63.
This reduces module size and brings no functional changes.

protected by XPU. XPU may sometime falsely detect clean cache eviction
as "write" into the write protected region leading to secure interrupt
which causes an endless loop somewhere in Trust Zone.
The only reason it is working right now is because Qualcomm Hypervisor
maps the same region as Non-Cacheable memory in Stage 2 translation
tables. The issue manifests if we want to use another hypervisor (like
Xen or KVM), which does not know anything about those specific mappings.
Changing the mapping of cmd-db memory from MEMREMAP_WB to MEMREMAP_WT/WC
removes dependency on correct mappings in Stage 2 tables. This patch
fixes the issue by updating the mapping to MEMREMAP_WC.
I tested this on SA8155P with Xen.

Introduce tracepoint support for smp2p to enable
communication logging between local and remote processors.
Include tracepoints with information about the remote subsystem
name, negotiation details, supported features, bit change
notifications, and ssr activity. These logs are useful for
debugging issues between subsystems.

The pd-mapper driver doesn't make sense on non Qualcomm systems. Let's

Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.

patchsets (devmem among them) did not make it in time.
Core & protocols
----------------
- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT.
- Use flex array for netdevice priv area, ensure its cache alignment.
- Add a sysctl knob to allow user to specify a default rto_min at socket
init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful.
- Support scheduling transmission of packets based on CLOCK_TAI.
- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned off
using cpusets.
- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address.
- Allow configuration of multipath hash seed, to both allow synchronizing
hashing of two routers, and preventing partial accidental sync.
- Improve TCP compliance with RFC 9293 for simultaneous connect().
- Support sending NAT keepalives in IPsec ESP in UDP states. Userspace
IKE daemon had to do this before, but the kernel can better keep
track of it.
- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled.
- Introduce IPPROTO_SMC for selecting SMC when socket is created.
- Allow UDP GSO transmit from devices with no checksum offload.
- openvswitch: add packet sampling via psample, separating the sampled
traffic from "upcall" packets sent to user space for forwarding.
- nf_tables: shrink memory consumption for transaction objects.
Things we sprinkled into general kernel code
--------------------------------------------
- Power Sequencing subsystem (used by Qualcomm Bluetooth driver
for QCA6390).
- Add IRQ information in sysfs for auxiliary bus.
- Introduce guard definition for local_lock.
- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures.
BPF
---
- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered.
- Add new kfuncs for a generic, open-coded bits iterator.
- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head.
- Support resilient split BTF which cuts down on duplication and makes
BTF as compact as possible WRT BTF from modules.
- Add support for dumping kfunc prototypes from BTF which enables both
detecting as well as dumping compilable prototypes for kfuncs.
- riscv64 BPF JIT improvements in particular to add 12-argument support
for BPF trampolines and to utilize bpf_prog_pack for the latter.
- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs.
Driver API
----------
- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose.
- Expand Power Sourcing (PoE) status with power, class and failure
reason. Support setting power limits.
- Track additional RSS contexts in the core, make sure configuration
changes don't break them.
- Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated ESP
data paths.
- Support updating firmware on SFP modules.
Tests and tooling
-----------------
- mptcp: use net/lib.sh to manage netns.
- TCP-AO and TCP-MD5: replace debug prints used by tests with
tracepoints.
- openvswitch: make test self-contained (don't depend on OvS CLI tools).
Drivers
-------
- Ethernet high-speed NICs:
- Broadcom (bnxt):
- increase the max total outstanding PTP TX packets to 4
- add timestamping statistics support
- implement netdev_queue_mgmt_ops
- support new RSS context API
- Intel (100G, ice, idpf):
- implement FEC statistics and dumping signal quality indicators
- support E825C products (with 56Gbps PHYs)

Merge tag 'net-next-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:
"Not much excitement - a handful of large patchsets (devmem among them)
did not make it in time.
Core & protocols:
- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT
- Use flex array for netdevice priv area, ensure its cache alignment
- Add a sysctl knob to allow user to specify a default rto_min at
socket init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful
- Support scheduling transmission of packets based on CLOCK_TAI
- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned
off using cpusets
- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address
- Allow configuration of multipath hash seed, to both allow
synchronizing hashing of two routers, and preventing partial
accidental sync
- Improve TCP compliance with RFC 9293 for simultaneous connect()
- Support sending NAT keepalives in IPsec ESP in UDP states.
Userspace IKE daemon had to do this before, but the kernel can
better keep track of it
- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled
- Introduce IPPROTO_SMC for selecting SMC when socket is created
- Allow UDP GSO transmit from devices with no checksum offload
- openvswitch: add packet sampling via psample, separating the
sampled traffic from "upcall" packets sent to user space for
forwarding
- nf_tables: shrink memory consumption for transaction objects
Things we sprinkled into general kernel code:
- Power Sequencing subsystem (used by Qualcomm Bluetooth driver for
QCA6390) [ Already merged separately - Linus ]
- Add IRQ information in sysfs for auxiliary bus
- Introduce guard definition for local_lock
- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures
BPF:
- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered
- Add new kfuncs for a generic, open-coded bits iterator
- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head
- Support resilient split BTF which cuts down on duplication and
makes BTF as compact as possible WRT BTF from modules
- Add support for dumping kfunc prototypes from BTF which enables
both detecting as well as dumping compilable prototypes for kfuncs
- riscv64 BPF JIT improvements in particular to add 12-argument
support for BPF trampolines and to utilize bpf_prog_pack for the
latter
- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs
Driver API:
- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose
- Expand Power Sourcing (PoE) status with power, class and failure
reason. Support setting power limits
- Track additional RSS contexts in the core, make sure configuration
changes don't break them
- Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated
ESP data paths
- Support updating firmware on SFP modules
Tests and tooling:
- mptcp: use net/lib.sh to manage netns
- TCP-AO and TCP-MD5: replace debug prints used by tests with
tracepoints
- openvswitch: make test self-contained (don't depend on OvS CLI
tools)
Drivers:
- Ethernet high-speed NICs:
- Broadcom (bnxt):
- increase the max total outstanding PTP TX packets to 4
- add timestamping statistics support
- implement netdev_queue_mgmt_ops
- support new RSS context API

The updates to the mediatek, allwinner, ti, tegra, microchip, stm32,
samsung, imx, zynq and amlogic platoforms are farily small maintenance
changes, either addressing minor mistakes or enabling additional hardware.
The qualcomm platform changes add a number of features and are larger
than the other ones combined, introducing the use of linux/cleanup.h
across several drivers, adding support for Snapdragon X1E and other
SoCs in platform drivers, a new "protection domain mapper" driver, and a
"shared memory bridge" driver.
The cznic "turris omnia" router based on Marvell Armada gets a platform
driver that talks to the board specific microcontroller.
The reset and cache subsystems get a few minor updates to SoC specific
drivers, while the ff-a, scmi and optee firmware drivers get some
code refactoring and new features.

Not all registers in PMU_ALIVE block support atomic set/clear operations.
GS101_SYSIP_DAT0 and GS101_SYSTEM_CONFIGURATION registers are two regs
where attempting atomic access fails.
As documentation on exactly which registers support atomic operations is
not forthcoming. We default to atomic access, unless the register is
explicitly added to the tensor_is_atomic() function. Update the comment
to reflect this as well.

Support for Shared Memory (shm) Bridge is added, which provides a
stricter interface for handling of buffers passed to TrustZone.
The X1Elite platform is added to uefisecapp allow list, to instantiate
the efivars implementation.
A new in-kernel implementation of the pd-mapper (or servreg) service is
introduced, to replace the userspace dependency for USB Type-C and
battery management.
Support for sharing interrupts across multiple bwmon instances is added,
and a refcount imbalance issue is corrected.
The LLCC support for recent platforms is corrected, and SA8775P support
is added.
A new interface is added to SMEM, to expose "feature codes". One example
of the usecase for this is to indicate to the GPU driver which

qmc_chan_get_byphandle() and the resource managed version retrieve a
channel from a simple phandle.
Extend the API and introduce qmc_chan_get_byphandles_index() and the
resource managed version in order to retrieve a channel from a phandle
list using the provided index to identify the phandle in the list.
Also update qmc_chan_get_byphandle() and the resource managed version to
use qmc_chan_get_byphandles_index() and so avoid code duplication.

In the match() callback, the struct device_driver * should not be
changed, so change the function callback to be a const *. This is one
step of many towards making the driver core safe to have struct
device_driver in read-only memory.
Because the match() callback is in all busses, all busses are modified
to handle this properly. This does entail switching some container_of()
calls to container_of_const() to properly handle the constant *.
For some busses, like PCI and USB and HV, the const * is cast away in
the match callback as those busses do want to modify those structures at
this point in time (they have a local lock in the driver structure.)
That will have to be changed in the future if they wish to have their
struct device * in read-only-memory.

When using /proc/interrupts to collect statistics on smp2p interrupt
counts, it is hard to distinguish the different instances of smp2p from
each other. For example to debug a processor boot issue, the ready and
handover interrupts are checked for sanity to ensure the firmware
reached a specific initialization stage.
Remove "smp2p" string from the irq request so that the irq will default
to the device name. Add an .irq_print_chip() callback to print the irq
chip name as the device name. These two changes allow for a unique name
to be used in /proc/interrupts as shown below.
/ # cat /proc/interrupts | grep smp2p
18: ... ipcc 196610 Edge smp2p-adsp
20: ... ipcc 131074 Edge smp2p-modem

Since commit 0166dc11be ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.
It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.
As a minor optimization, this also lets us drop of_match_ptr() and
ifdef-guarding, as we now know what they will resolve to, we might as
well save cpp some work.

Add cmdq_pkt_logic_command to support math operation.
cmdq_pkt_logic_command can append logic command to the CMDQ packet,
ask GCE to execute a arithmetic calculate instruction,
such as add, subtract, multiply, AND, OR and NOT, etc.
Note that all arithmetic instructions are unsigned calculations.
If there are any overflows, GCE will sent the invalid IRQ to notify
CMDQ driver.

When 9-bit alpha is enabled, its value will be converted from 0-255 to
0-256 (255 = not defined). This is designed for special HDR related
calculation, which should be disabled by default, otherwise, alpha
blending will not work correctly.

Commit 6f4429e21a ("soc/tegra: pmc: Update address mapping sequence
for PMC apertures") updated the resource lookup code in the PMC driver.
Instead of calling platform_get_resource_byname() and
devm_ioremap_resource() simplify the code by simply calling
devm_platform_ioremap_resource_byname().

For SoCs like gs101 that need a special regmap, register this with
of_syscon_register_regmap api, so it can be returned by
syscon_regmap_lookup_by_phandle() and friends.
For SoCs that don't require a custom regmap, revert back to syscon
creating the mmio regmap rather than duplicating the logic here.
exynos_get_pmu_regmap_by_phandle() api is also updated to retrieve
the regmap via syscon. The exynos_get_pmu_regmap_by_phandle() api
is kept around until fw_devlink support for syscon property is added
for the pinctrl-samsung driver that also runs at postcore_initcall
level.
All other exynos client drivers can revert back to
syscon_regmap_lookup_by_phandle().

The multiple BWMONv4 instances available on the X1E80100 SoC use the
same interrupt number. Mark them are shared to allow for re-use across
instances.
Using IRQF_SHARED coupled with devm_request_threaded_irq implies that
the irq can still trigger during/after bwmon_remove due to other active
bwmon instances. Handle this race by relying on bwmon_disable to disable
the interrupt and coupled with explicit request/free irqs.

DIMLIB's capabilities are supplied by the dim, net_dim, and
rdma_dim objects, and dim's interfaces solely act as a base for
net_dim and rdma_dim and are not explicitly used anywhere else.
rdma_dim is utilized by the infiniband driver, while net_dim
is for network devices, excluding the soc/fsl driver.
In this patch, net_dim relies on some NET's interfaces, thus
DIMLIB needs to explicitly depend on the NET Kconfig.
The soc/fsl driver uses the functions provided by net_dim, so
it also needs to depend on NET.

Existing userspace protection domain mapper implementation has several
issue. It doesn't play well with CONFIG_EXTRA_FIRMWARE, it doesn't
reread JSON files if firmware location is changed (or if firmware was
not available at the time pd-mapper was started but the corresponding
directory is mounted later), etc.
Provide in-kernel service implementing protection domain mapping
required to work with several services, which are provided by the DSP
firmware.
This module is loaded automatically by the remoteproc drivers when
necessary via the symbol dependency. It uses a root node to match a
protection domains map for a particular board. It is not possible to
implement it as a 'driver' as there is no corresponding device.

Recent (SM8550+ ish) Qualcomm SoCs have a new mechanism for precisely
identifying the specific SKU and the precise speed bin (in the general
meaning of this word, anyway): a pair of values called Product Code
and Feature Code.
Based on this information, we can deduce the available frequencies for
things such as Adreno. In the case of Adreno specifically, Pcode is
useless for non-prototype SoCs.
Introduce a getter for the feature code and export it.
