Updates for v6.16
CI:
- uprev mesa
GPU:
- ACD (Adaptive Clock Distribution) support for X1-85. This is required
enable the higher frequencies.
- Drop fictional `address_space_size`. For some older devices, the address
space size is limited to 4GB to avoid potential 64b rollover math problems
in the fw. For these, an `ADRENO_QUIRK_4GB_VA` quirk is added. For
everyone else we get the address space size from the SMMU `ias` (input
address sizes), which is usually 48b.
- Improve robustness when GMU HFI responses time out
- Fix crash when throttling GPU immediately during boot
- Fix for rgb565_predicator on Adreno 7c3
- Remove `MODULE_FIRMWARE()`s for GPU, the GPU can load the firmware after
probe and having partial set of fw (ie. sqe+gmu but not zap) causes problems

Introduce Rust support for the `xarray` data structure:
- Add a rust abstraction for the `xarray` data structure. This abstraction
allows rust code to leverage the `xarray` to store types that implement
`ForeignOwnable`. This support is a dependency for memory backing feature of
the rust null block driver, which is waiting to be merged.
- Set up an entry in MAINTAINERS for the xarray rust support. Patches will go
to the new rust xarray tree and then via the rust subsystem tree for now.
`kernel` crate:
- Allow `ForeignOwnable` to carry information about the pointed-to type. This
helps asserting alignment requirements for the pointer passed to the foreign
language.

"Introduce Rust support for the 'xarray' data structure:
- Add a Rust abstraction for the 'xarray' data structure. This
abstraction allows Rust code to leverage the 'xarray' to store
types that implement 'ForeignOwnable'. This support is a dependency
for memory backing feature of the Rust null block driver, which is
waiting to be merged.
- Set up an entry in MAINTAINERS for the XArray Rust support. Patches
will go to the new Rust XArray tree and then via the Rust subsystem
tree for now.
'kernel' crate:
- Allow 'ForeignOwnable' to carry information about the pointed-to
type. This helps asserting alignment requirements for the pointer
passed to the foreign language."

Precision Time Management (PTM) mechanism defined in PCIe spec r6.0,
sec 6.21 allows precise coordination of timing information across multiple
components in a PCIe hierarchy with independent local time clocks.
PCI core already supports enabling PTM in the root port and endpoint
devices through PTM Extended Capability registers. But the PTM context
supported by the PTM capable components such as Root Complex (RC) and
Endpoint (EP) controllers were not exposed as of now. Part of the reason is
that the spec doesn't define how the context information is exposed to the
software and left it to the vendor implementation. So there is no
standardized way to get access to the context information and each vendor
have defined their own way.
This commit adds debugfs support to expose the PTM context to userspace
from both PCIe RC and EP controllers. Since the context information is
exposed in a vendor specific way, the debugfs interface allows the
controller drivers to implement callbacks for each attribute, to be called
by the generic PTM driver.
The Controller drivers are expected to call pcie_ptm_create_debugfs() to
create the debugfs attributes for the PTM context and call
pcie_ptm_destroy_debugfs() to destroy them. The drivers should also
populate the relevant callbacks in the 'struct pcie_ptm_ops' structure
based on the controller implementation.
Below PTM context are exposed through debugfs:
PCIe RC
=======
1. PTM Local clock
2. PTM T2 timestamp
3. PTM T3 timestamp
4. PTM Context valid
PCIe EP
=======
1. PTM Local clock
2. PTM T1 timestamp
3. PTM T4 timestamp
4. PTM Master clock
5. PTM Context update

Right now these are performed in kernel/fork.c which is odd and a
violation of separation of concerns, as well as preventing us from
integrating this and related logic into userland VMA testing going
forward.
There is a fly in the ointment - nommu - mmap.c is not compiled if
CONFIG_MMU not set, and neither is vma.c.
To square the circle, let's add a new file - vma_init.c. This will be
compiled for both CONFIG_MMU and nommu builds, and will also form part of
the VMA userland testing.
This allows us to de-duplicate code, while maintaining separation of
concerns and the ability for us to userland test this logic.
Update the VMA userland tests accordingly, additionally adding a
detach_free_vma() helper function to correctly detach VMAs before freeing
them in test code, as this change was triggering the assert for this.

Patch series "move all VMA allocation, freeing and duplication logic to
mm", v3.
Currently VMA allocation, freeing and duplication exist in kernel/fork.c,
which is a violation of separation of concerns, and leaves these functions
exposed to the rest of the kernel when they are in fact internal
implementation details.
Resolve this by moving this logic to mm, and making it internal to vma.c,
vma.h.
This also allows us, in future, to provide userland testing around this
functionality.
We additionally abstract dup_mmap() to mm, being careful to ensure
kernel/fork.c acceses this via the mm internal header so it is not exposed
elsewhere in the kernel.
As part of this change, also abstract initial stack allocation performed
in __bprm_mm_init() out of fs code into mm via the
create_init_stack_vma(), as this code uses vm_area_alloc() and
vm_area_free().
In order to do so sensibly, we introduce a new mm/vma_exec.c file, which
contains the code that is shared by mm and exec. This file is added to
both memory mapping and exec sections in MAINTAINERS so both sets of
maintainers can maintain oversight.
As part of this change, we also move relocate_vma_down() to mm/vma_exec.c
so all shared mm/exec functionality is kept in one place.
We add code shared between nommu and mmu-enabled configurations in order
to share VMA allocation, freeing and duplication code correctly while also
keeping these functions available in userland VMA testing.
This is achieved by adding a mm/vma_init.c file which is also compiled by
the userland tests.
This patch (of 4):
There is functionality that overlaps the exec and memory mapping
subsystems. While it properly belongs in mm, it is important that exec
maintainers maintain oversight of this functionality correctly.
We can establish both goals by adding a new mm/vma_exec.c file which
contains these 'glue' functions, and have fs/exec.c import them.
As a part of this change, to ensure that proper oversight is achieved, add
the file to both the MEMORY MAPPING and EXEC & BINFMT API, ELF sections.
scripts/get_maintainer.pl can correctly handle files in multiple entries
and this neatly handles the cross-over.

We introduced KHO into Linux: A framework that allows Linux to pass
metadata and memory across kexec from Linux to Linux. KHO reuses fdt as
file format and shares a lot of the same properties of firmware-to- Linux
boot formats: It needs a stable, documented ABI that allows for forward
and backward compatibility as well as versioning.
As first user of KHO, we introduced memblock which can now preserve memory
ranges reserved with reserve_mem command line options contents across
kexec, so you can use the post-kexec kernel to read traces from the
pre-kexec kernel.
This patch adds memblock schemas similar to "device" device tree ones to a
new kho bindings directory. This allows us to force contributors to
document the data that moves across KHO kexecs and catch breaking change
during review.

Add the infrastructure to generate Kexec HandOver metadata. Kexec
HandOver is a mechanism that allows Linux to preserve state - arbitrary
properties as well as memory locations - across kexec.
It does so using 2 concepts:
1) KHO FDT - Every KHO kexec carries a KHO specific flattened device tree
blob that describes preserved memory regions. Device drivers can
register to KHO to serialize and preserve their states before kexec.
2) Scratch Regions - CMA regions that we allocate in the first kernel.
CMA gives us the guarantee that no handover pages land in those
regions, because handover pages must be at a static physical memory
location. We use these regions as the place to load future kexec
images so that they won't collide with any handover data.

Prepare for Intel IPU E2000 (GEN3)
This is the first part in introducing RDMA support for idpf.
----------------------------------------------------------------
Tatyana Nikolova says:
To align with review comments, the patch series introducing RDMA
RoCEv2 support for the Intel Infrastructure Processing Unit (IPU)
E2000 line of products is going to be submitted in three parts:
1. Modify ice to use specific and common IIDC definitions and
pass a core device info to irdma.
2. Add RDMA support to idpf and modify idpf to use specific and
common IIDC definitions and pass a core device info to irdma.
3. Add RDMA RoCEv2 support for the E2000 products, referred to as
GEN3 to irdma.
This first part is a 5 patch series based on the original
"iidc/ice/irdma: Update IDC to support multiple consumers" patch
to allow for multiple CORE PCI drivers, using the auxbus.
Patches:
1) Move header file to new name for clarity and replace ice
specific DSCP define with a kernel equivalent one in irdma
2) Unify naming convention
3) Separate header file into common and driver specific info
4) Replace ice specific DSCP define with a kernel equivalent
one in ice
5) Implement core device info struct and update drivers to use it

Add the initial nova-drm driver skeleton.
nova-drm is connected to nova-core through the auxiliary bus and
implements the DRM parts of the nova driver stack.
For now, it implements the fundamental DRM abstractions, i.e. creates a
DRM device and registers it, exposing a three sample IOCTLs.
DRM_IOCTL_NOVA_GETPARAM
- provides the PCI bar size from the bar that maps the GPUs VRAM
from nova-core
DRM_IOCTL_NOVA_GEM_CREATE
- creates a new dummy DRM GEM object and returns a handle
DRM_IOCTL_NOVA_GEM_INFO
- provides metadata for the DRM GEM object behind a given handle
I implemented a small userspace test suite [1] that utilizes this
interface.

Prior to the recently applied commit that permits this merge,
mprotect()'ing a faulted VMA, adjacent to an unfaulted VMA, such that the
two share characteristics would fail to merge due to what appear to be
unintended consequences of commit 965f55dea0 ("mmap: avoid merging
cloned VMAs").
Now we have fixed this bug, assert that we can indeed merge anonymous VMAs
this way.
Also assert that forked source/target VMAs are equally rejected.
Previously, all empty target anon merges with one VMA faulted and the
other unfaulted would be rejected incorrectly, now we ensure that unforked
merge, but forked do not.
Additionally, add the new test file to the MEMORY MAPPING section in
MAINTAINERS, as these tests are explicitly memory mapping related.

1. Quirk framework to handle buggy firmware
With SCMI gaining broader adoption across arm64 platforms, it's
increasingly important to address how we consistently manage out-of-spec
SCMI firmware already deployed in the field. This change introduces a
lightweight quirk framework built around static_keys, enabling developers to:
- Define quirks and their match criteria, which can include:
o A list of compatibles ({ comp, comp2, NULL })
o Vendor ID / Sub-Vendor ID
o Firmware implementation version ranges ([Min_Vers, Max_Vers])
Matching proceeds from the most specific (longest match) to the least
specific. NULL entries are treated as wildcards (i.e., match any value).
This flexibility allows matching very specific combinations or just a
general compatible string.
The quirk code blocks/snippets implementing the workaround are placed near
their intended usage and guarded by a static_key that's tied to the quirk.
Once the SCMI core stack is initialized and retrieves platform info via the
base protocol, any matching quirks will have their associated static_keys
enabled.
2. Quirk for Qualcomm X1E platforms
On some Qualcomm X1E platforms, such as the Lenovo ThinkPad T14s, the
SCMI firmware fails to set the FastChannel support bit for PERF_LEVEL_GET,
yet it crashes when the driver attempts to fall back to standard messaging
which is clearly out-of-spec behavior.
To work around this, the new SCMI quirk framework is used to
unconditionally enable FC initialization for this firmware version.
In the future, once the fixed firmware version is identified, an upper
version bound can be added to the quirk match criteria. Alternatively,
matching can be further restricted using a SoC-specific compatible string
if always enabling FC proves problematic elsewhere.
3. Support for NXP i.MX LMM/CPU vendor protocol extensions
The i.MX95 System Manager (SM) implements Logical Machine Management (LMM)
and a CPU protocol to manage Logical Machines (LM) and CPUs (e.g., M7).
These changes integrate the vendor-specific protocol extensions
implementing the LMM and CPU protocols for the i.MX95, facilitating
standardized communication between the operating system and the platform's
firmware, which will be used by remoteproc drivers. The changes also
include the necessary device tree bindings.
4. Miscellaneous cleanups/changes
These mainly include polling support in SCMI raw mode. The cleanups
centralize error logging for SCMI device creation into a single helper
function, consolidate the device matching logic into a single function, and
ensure that devices must have a name for registration—removing support for
unnamed devices when matching drivers and devices for probing. Transport
devices are now excluded from bus matching, and the correct assignment of
the parent device for the arm-scmi platform device is ensured in the
transport drivers.

Arm SCMI updates for v6.16
1. Quirk framework to handle buggy firmware
With SCMI gaining broader adoption across arm64 platforms, it's
increasingly important to address how we consistently manage out-of-spec
SCMI firmware already deployed in the field. This change introduces a
lightweight quirk framework built around static_keys, enabling developers to:
- Define quirks and their match criteria, which can include:
o A list of compatibles ({ comp, comp2, NULL })
o Vendor ID / Sub-Vendor ID
o Firmware implementation version ranges ([Min_Vers, Max_Vers])
Matching proceeds from the most specific (longest match) to the least
specific. NULL entries are treated as wildcards (i.e., match any value).
This flexibility allows matching very specific combinations or just a
general compatible string.
The quirk code blocks/snippets implementing the workaround are placed near
their intended usage and guarded by a static_key that's tied to the quirk.
Once the SCMI core stack is initialized and retrieves platform info via the
base protocol, any matching quirks will have their associated static_keys
enabled.
2. Quirk for Qualcomm X1E platforms
On some Qualcomm X1E platforms, such as the Lenovo ThinkPad T14s, the
SCMI firmware fails to set the FastChannel support bit for PERF_LEVEL_GET,
yet it crashes when the driver attempts to fall back to standard messaging
which is clearly out-of-spec behavior.
To work around this, the new SCMI quirk framework is used to
unconditionally enable FC initialization for this firmware version.
In the future, once the fixed firmware version is identified, an upper
version bound can be added to the quirk match criteria. Alternatively,
matching can be further restricted using a SoC-specific compatible string
if always enabling FC proves problematic elsewhere.
3. Support for NXP i.MX LMM/CPU vendor protocol extensions
The i.MX95 System Manager (SM) implements Logical Machine Management (LMM)
and a CPU protocol to manage Logical Machines (LM) and CPUs (e.g., M7).
These changes integrate the vendor-specific protocol extensions
implementing the LMM and CPU protocols for the i.MX95, facilitating
standardized communication between the operating system and the platform's
firmware, which will be used by remoteproc drivers. The changes also
include the necessary device tree bindings.
4. Miscellaneous cleanups/changes
These mainly include polling support in SCMI raw mode. The cleanups
centralize error logging for SCMI device creation into a single helper
function, consolidate the device matching logic into a single function, and
ensure that devices must have a name for registration—removing support for
unnamed devices when matching drivers and devices for probing. Transport
devices are now excluded from bus matching, and the correct assignment of
the parent device for the arm-scmi platform device is ensured in the
transport drivers.

Some NETC functionality is controlled using control messages sent to the
hardware using BD ring interface with 32B descriptor similar to transmit
BD ring used on ENETC. This BD ring interface is referred to as command
BD ring. It is used to configure functionality where the underlying
resources may be shared between different entities or being too large to
configure using direct registers. Therefore, a messaging protocol called
NETC Table Management Protocol (NTMP) is provided for exchanging
configuration and management information between the software and the
hardware using the command BD ring interface.
For the management protocol of LS1028A has been retroactively named NTMP
1.0, and its implementation is in enetc_cbdr.c and enetc_qos.c. However,
NTMP of i.MX95 has been upgraded to version 2.0, which is incompatible
with LS1028A, because the message formats have been changed. Therefore,
add the netc-lib driver to support NTMP 2.0 to operate various tables.
Note that, only MAC address filter table and RSS table are supported at
the moment. More tables will be supported in subsequent patches.
It is worth mentioning that the purpose of the netc-lib driver is to
provide some NTMP-based generic interfaces for ENETC and NETC Switch
drivers. Currently, it only supports the configurations of some tables.
Interfaces such as tc flower and debugfs will be added in the future.

This sample kernel module demonstrates how to make MRs accessible to user
mode through the tsm-mr library.
Once loaded, this module registers a `miscdevice` that host a set of
emulated measurement registers as shown in the directory tree below.
/sys/class/misc/tsm_mr_sample
└── measurements
├── config_mr
├── report_digest:sha512
├── rtmr0:sha256
├── rtmr1:sha384
├── rtmr_crypto_agile:sha256
├── rtmr_crypto_agile:sha384
└── static_mr:sha384
Among the MRs in this example:
- `config_mr` demonstrates a hashless MR, like MRCONFIGID in Intel TDX or
HOSTDATA in AMD SEV.
- `static_mr` demonstrates a static MR. The suffix `:sha384` indicates its
value is a sha384 digest.
- `rtmr0` is an RTMR with `TSM_MR_F_WRITABLE` **cleared**, preventing
direct extensions; as a result, the attribute `rtmr0:sha256` is
read-only.
- `rtmr1` is an RTMR with `TSM_MR_F_WRITABLE` **set**, permitting direct
extensions; thus, the attribute `rtmr1:sha384` is writable.
- `rtmr_crypto_agile` demonstrates a "single" MR that supports multiple
hash algorithms. Each supported algorithm has a corresponding digest,
usually referred to as a "bank" in TCG terminology. In this specific
sample, the 2 banks are aliased to `rtmr0` and `rtmr1`, respectively.
- `report_digest` contains the digest of the internal report structure
living in this sample module's memory. It is to demonstrate the use of
the `TSM_MR_F_LIVE` flag. Its value changes each time an RTMR is
extended.

Introduce new TSM Measurement helper library (tsm-mr) for TVM guest drivers
to expose MRs (Measurement Registers) as sysfs attributes, with Crypto
Agility support.
Add the following new APIs (see include/linux/tsm-mr.h for details):
- tsm_mr_create_attribute_group(): Take on input a `struct
tsm_measurements` instance, which includes one `struct
tsm_measurement_register` per MR with properties like `TSM_MR_F_READABLE`
and `TSM_MR_F_WRITABLE`, to determine the supported operations and create
the sysfs attributes accordingly. On success, return a `struct
attribute_group` instance that will typically be included by the guest
driver into `miscdevice.groups` before calling misc_register().
- tsm_mr_free_attribute_group(): Free the memory allocated to the attrubute
group returned by tsm_mr_create_attribute_group().
tsm_mr_create_attribute_group() creates one attribute for each MR, with
names following this pattern:
MRNAME[:HASH]
- MRNAME - Placeholder for the MR name, as specified by
`tsm_measurement_register.mr_name`.
- :HASH - Optional suffix indicating the hash algorithm associated with
this MR, as specified by `tsm_measurement_register.mr_hash`.
Support Crypto Agility by allowing multiple definitions of the same MR
(i.e., with the same `mr_name`) with distinct HASH algorithms.
NOTE: Crypto Agility, introduced in TPM 2.0, allows new hash algorithms to
be introduced without breaking compatibility with applications using older
algorithms. CC architectures may face the same challenge in the future,
needing new hashes for security while retaining compatibility with older
hashes, hence the need for Crypto Agility.

The zoned loop block device driver allows a user to create emulated
zoned block devices using one regular file per zone as backing storage.
Compared to null_blk or scsi_debug, it has the advantage of allowing
emulating large zoned devices without requiring the same amount of
memory as the capacity of the emulated device. Furthermore, zoned
devices emulated with this driver can be re-started after a host reboot
without any loss of the state of the device zones, which is something
that null_blk and scsi_debug do not support.
This initial implementation is simple and does not support zone resource
limits. That is, a zoned loop block device limits for the maximum number
of open zones and maximum number of active zones is always 0.
This driver can be either compiled in-kernel or as a module, named
"zloop". Compilation of this driver depends on the block layer support
for zoned block device (CONFIG_BLK_DEV_ZONED must be set).
Using the zloop driver to create and delete zoned block devices is
done by writing commands to the zoned loop control character device file
(/dev/zloop-control). Creating a device is done with:
$ echo "add [options]" > /dev/zloop-control
The options available for the "add" operation cat be listed by reading
the zloop-control device file:
$ cat /dev/zloop-control
add id=%d,capacity_mb=%u,zone_size_mb=%u,zone_capacity_mb=%u,conv_zones=%u,base_dir=%s,nr_queues=%u,queue_depth=%u
remove id=%d
The options available allow controlling the zoned device total
capacity, zone size, zone capactity of sequential zones, total number
of conventional zones, base directory for the zones backing file, number
of I/O queues and the maximum queue depth of I/O queues.
Deleting a device is done using the "remove" command:
$ echo "remove id=0" > /dev/zloop-control
This implementation passes various tests using zonefs and fio (t/zbd
tests) and provides a state machine for zone conditions that is
compliant with the T10 ZBC and NVMe ZNS specifications.

In order to achieve a 4 MSPS rate on a 16-bit ADC with a 80 MHz SCLK
using the SPI offload feature of the AXI SPI Engine, we need to shave
off some time that is spent executing unnecessary instructions. There
are a few one-time setup instructions that can be moved so that they
execute only once when the SPI offload trigger is enabled rather than
repeating each time the offload is triggered. Additionally, a recent
change to the IP block allows dropping the SYNC instruction completely.
With these changes, we are left with only the 3 instructions that are
needed to to assert CS, transfer the data, and deassert CS. This makes
3 + 16 * 12.5 ns = 237.5 ns < 250 ns which is comfortably within the
available time period.
The EC of OneXPlayer devices used to only control the fan. This is no
longer the case, with the EC of OneXPlayer gaining additional

As it will be beneficial from a complexity perspective to retain this

Also, remove the hwmon documentation to prepare moving it to
Documentation/ABI/.

Toradex SMARC iMX8MP and SMARC iMX95 SoM modules use a small Embedded
Controller (EC) to manage power and reset functions and related SMARC
signals.
This driver implements power-off and reboot handlers, communicating with
the EC via I2C to issue the appropriate power management commands.
During probe, the driver logs the Embedded Controller ID (unique ID for
each SMARC board supported) in hex format along with the firmware version.

Delete the hda_cs_dsp module and move the one array and one function
that is used by the cs35l41_hda driver into that driver.
The cs35l41 and cs35l56 drivers stopped creating ALSA controls to
wrap firmware controls. The reasons are explained in:
commit 312c04cee4 ("ALSA: hda: cs35l41: Stop creating ALSA Controls
for firmware coefficients")
and
commit 34e1b1bb73 ("ALSA: hda: cs35l56: Stop creating ALSA controls
for firmware coefficients")
The cs35l56_hda driver now doesn't use hda_cs_dsp_ctl at all. The
cs35l41_hda driver only uses the small array of firmware names and the
function to read a control value. All other functions and data in
hda_cs_dsp_ctl are unused. There is no need to keep a separate module
for such a small amount of data and code that is only used by one driver,
so remove the whole module.

Pull vfs fixes from Christian Brauner:
- For some reason we went from zero to three maintainers for HFS/HFS+
in a matter of days. The lesson to learn from this might just be that
we need to threaten code removal more often!?
- Fix a regression introduced by enabling large folios for lage logical
block sizes. This has caused issues for noref migration with large
folios due to sleeping while in an atomic context.
New sleeping variants of pagecache lookup helpers are introduced.
These helpers take the folio lock instead of the mapping's private
spinlock. The problematic users are converted to the sleeping
variants and serialize against noref migration. Atomic users will
bail on seeing the new BH_Migrate flag.
This also shrinks the critical region of the mapping's private lock
and the new blocking callers reduce contention on the spinlock for
bdev mappings.
- Fix two bugs in do_move_mount() when with MOVE_MOUNT_BENEATH. The
first bug is using a mountpoint that is located on a mount we're not
holding a reference to. The second bug is putting the mountpoint
after we've called namespace_unlock() as it's no longer guaranteed
that it does stay a mountpoint.
- Remove a pointless call to vfs_getattr_nosec() in the devtmpfs code
just to query i_mode instead of simply querying the inode directly.
This also avoids lifetime issues for the dm code by an earlier bugfix
this cycle that moved bdev_statx() handling into vfs_getattr_nosec().
- Fix AT_FDCWD handling with getname_maybe_null() in the xattr code.
- Fix a performance regression for files when multiple callers issue a
close when it's not the last reference.
- Remove a duplicate noinline annotation from pipe_clear_nowait().

Merge series from "Peng Fan (OSS)" <peng.fan@oss.nxp.com>:
Per Mark's comments in [1], each driver in one patchset and not merge
the changes to one driver in one patch, so worked out three patches.
- Sort the included headers.
- Drop sound/tpa6130a2-plat.h because no user is creating the device using
platform data
- Covert to GPIO descriptors
Checking the DTS polarity, all users are using GPIOD_ACTIVE_HIGH.
so all should work as expected with this patch.
I not have hardware to test, just my best effort to do this.

Change the references to Cirrus Logic files under include/sound to be a
wildcard of all cs* and use X: to exclude the three cs* files that are not
related to ASoC.
This means that new Cirrus Logic files added to include/sound will be
picked up automatically as an ASoC file without any changes to MAINTAINERS.
New files are most likely to be for ASoC drivers now.
It's also easier to manage than ranges of wildcarding for different sets of

The Rockchip RK3576 SoC features a new audio controller, the Serial
Audio Interface, or SAI for short. It is capable of both sending and
receiving audio over up to 4 lanes for each direction using the I2S,
PCM or TDM formats.
This driver is derived from the downstream vendor driver. That is why
its original author, Sugar Zhang, is listed as a Co-developer, with
their signoff. Since adjustments to make the driver suitable for
upstream were quite extensive, I've added myself to the authors and put
myself as the commit author; all added bugs are my fault alone, and not
that of the original author at Rockchip.
The hardware is somewhat similar to the Rockchip I2S-TDM hardware when
judged based on their register map, except it uses the same mclk for
tx and rx. It appears to be much more flexible with regards to TDM.
The loopback stuff and mono mode are new as well.
In line with the changes that were made to the Rockchip I2S-TDM driver
after upstreaming, the mclk-calibrate functionality was dropped, and
setting the mclk rate properly is now left up to the Common Clock
Framework, similar to how it is in the upstream I2S-TDM driver now.
A spinlock has been introduced to protect register write accesses that
depend on the bclk/fs to be stopped, i.e. XFER[1:0] being 0. I couldn't
find whether the asoc core held a per-instance lock so only one callback
can run at a time, and so it seemed prudent to add this.
I couldn't successfully test whether TDM was working, though I've tried
with a TAS6424 codec board. I'm not sure yet whether to blame the codec
driver, this version of the SAI driver, or the vendor implementation of
the SAI driver. The TDM mask registers remain untouched in both this
version and the downstream vendor version, which is suspicious, though
the Linux ASoC core wouldn't be able to support the 128 (!!!) slots of
TDM the hardware supports anyway.
Regular old 2-channel stereo I2S thrown at an I2S stereo codec works
well though. I tested with the CPU-side SAI controller in provider mode
and an Everest ES8388 codec as the consumer.
Some vendor driver features (no-dmaengine, fifo rockchip performance
monitoring, many kcontrols) were dropped for this initial upstream
version. They can always be added later if they make sense for upstream.

The FPC202 dual port controller serves as a low speed signal aggregator for
common port types, notably SFP. It provides access to I2C and low-speed
GPIO signals of a downstream device through a single upstream control
interface.
Up to two logical I2C addresses can be accessed on each of the FPC202's
ports. The port controller acts as an I2C translator (ATR). It converts
addresses of incoming and outgoing I2C transactions. One use case of this
is accessing two SFP modules at logical address 0x50 from the same upstream
I2C controller, using two different client aliases.

Merge series from Andy Shevchenko <andriy.shevchenko@linux.intel.com>:
Recently in the discussion with David the idea of having
a common helper popped up. The helper converts the given
bits per word to bytes. The result will always be power-of-two
(e.g. for 37 bits it returns 8 bytes) or 0 for 0 input.
More details are in the respective code comment.
This mini-series introduces it and replaces current users
under drivers/spi and we expect more (and possibly some
lurking in other subsystems).
We place this under memory mapping as related to memory mapping
abstractions in the form of mm_struct and vm_area_struct (VMA). Now we
have separated out mmap/vma locking logic into the mmap_lock.c and
mmap_lock.h files, so this should encapsulate the majority of the mm
locking logic in the kernel.
Suren is best placed to maintain this logic as the core architect of VMA
locking as a whole.

The ovpn-cli tool can be compiled and used as selftest for the ovpn
kernel module.
[NOTE: it depends on libmedtls for decoding base64-encoded keys]
ovpn-cli implements the netlink and RTNL APIs and can thus be integrated
in any script for more automated testing.
Along with the tool, a bunch of scripts are provided that perform basic
functionality tests by means of network namespaces.
These scripts take part to the kselftest automation.
The output of the scripts, which will appear in the kselftest
reports, is a list of steps performed by the scripts plus some
output coming from the execution of `ping`, `iperf` and `ovpn-cli`
itself.
In general it is useful only in case of failure, in order to
understand which step has failed and why.
Please note: since peer sockets are tied to the userspace
process that created them (i.e. exiting the process will result
in closing the socket), every run of ovpn-cli that created
one will go to background and enter pause(), waiting for the
signal which will allow it to terminate.
Termination is accomplished at the end of each script by
issuing a killall command.

OpenVPN is a userspace software existing since around 2005 that allows
users to create secure tunnels.
So far OpenVPN has implemented all operations in userspace, which
implies several back and forth between kernel and user land in order to
process packets (encapsulate/decapsulate, encrypt/decrypt, rerouting..).
With `ovpn` we intend to move the fast path (data channel) entirely
in kernel space and thus improve user measured throughput over the
tunnel.
`ovpn` is implemented as a simple virtual network device driver, that
can be manipulated by means of the standard RTNL APIs. A device of kind
`ovpn` allows only IPv4/6 traffic and can be of type:
* P2P (peer-to-peer): any packet sent over the interface will be
encapsulated and transmitted to the other side (typical OpenVPN
client or peer-to-peer behaviour);
* P2MP (point-to-multipoint): packets sent over the interface are
transmitted to peers based on existing routes (typical OpenVPN
server behaviour).
After the interface has been created, OpenVPN in userspace can
configure it using a new Netlink API. Specifically it is possible
to manage peers and their keys.
The OpenVPN control channel is multiplexed over the same transport
socket by means of OP codes. Anything that is not DATA_V2 (OpenVPN
OP code for data traffic) is sent to userspace and handled there.
This way the `ovpn` codebase is kept as compact as possible while
focusing on handling data traffic only (fast path).
Any OpenVPN control feature (like cipher negotiation, TLS handshake,
rekeying, etc.) is still fully handled by the userspace process.
When userspace establishes a new connection with a peer, it first
performs the handshake and then passes the socket to the `ovpn` kernel
module, which takes ownership. From this moment on `ovpn` will handle
data traffic for the new peer.
When control packets are received on the link, they are forwarded to
userspace through the same transport socket they were received on, as
userspace is still listening to them.
Some events (like peer deletion) are sent to a Netlink multicast group.
Although it wasn't easy to convince the community, `ovpn` implements
only a limited number of the data-channel features supported by the
userspace program.
Each feature that made it to `ovpn` was attentively vetted to
avoid carrying too much legacy along with us (and to give a clear cut to
old and probalby-not-so-useful features).
Notably, only encryption using AEAD ciphers (specifically
ChaCha20Poly1305 and AES-GCM) was implemented. Supporting any other
cipher out there was not deemed useful.
Both UDP and TCP sockets are supported.
As explained above, in case of P2MP mode, OpenVPN will use the main system
routing table to decide which packet goes to which peer. This implies
that no routing table was re-implemented in the `ovpn` kernel module.
This kernel module can be enabled by selecting the CONFIG_OVPN entry
in the networking drivers section.
NOTE: this first patch introduces the very basic framework only.
Features are then added patch by patch, however, although each patch
will compile and possibly not break at runtime, only after having
applied the full set it is expected to see the ovpn module fully working.

Add dma_alloc_attrs() and dma_free_attrs() helpers to fix a build
error when CONFIG_HAS_DMA is not enabled.
Note that when CONFIG_HAS_DMA is enabled, dma_alloc_attrs() and
dma_free_attrs() are included in both bindings_generated.rs and
bindings_helpers_generated.rs. The former takes precedence so behavior
remains unchanged in that case.

Specifically list various Cirrus Logic and Wolfson Micro codec header files
under include/sound/ within the ASoC section of MAINTAINERS. Note that not
all the include/sound/cs* files are part of ASoC, so more-specific patterns
are needed.
These files are all part of ASoC codec drivers, and are owned by specific
Cirrus Logic and Wolfson Micro sections of MAINTAINERS. But the overall
include/sound/* maintainership is only Takashi Iwai and Jaroslav Kysela.
So by default get_maintainer.pl would only show Takashi and Jaroslav as
maintainers for any patch that changes these files without changing any
code under sound/soc.
There is a separate MAINTAINERS section for ASoC, so the headers must be
added there to make the ASoC maintainers show up in get_maintainer.pl.

DCCP was orphaned in 2021 by commit 054c4610bd ("MAINTAINERS: dccp:
move Gerrit Renker to CREDITS"), which noted that the last maintainer
had been inactive for five years.
In recent years, it has become a playground for syzbot, and most changes
to DCCP have been odd bug fixes triggered by syzbot. Apart from that,
the only changes have been driven by treewide or networking API updates
or adjustments related to TCP.
Thus, in 2023, we announced we would remove DCCP in 2025 via commit
b144fcaf46 ("dccp: Print deprecation notice.").
Since then, only one individual has contacted the netdev mailing list. [0]
There is ongoing research for Multipath DCCP. The repository is hosted
on GitHub [1], and development is not taking place through the upstream
community. While the repository is published under the GPLv2 license,
the scheduling part remains proprietary, with a LICENSE file [2] stating:
"This is not Open Source software."
The researcher mentioned a plan to address the licensing issue, upstream
the patches, and step up as a maintainer, but there has been no further
communication since then.
Maintaining DCCP for a decade without any real users has become a burden.
Therefore, it's time to remove it.
Removing DCCP will also provide significant benefits to TCP. It allows
us to freely reorganize the layout of struct inet_connection_sock, which
is currently shared with DCCP, and optimize it to reduce the number of
cachelines accessed in the TCP fast path.
Note that we keep DCCP netfilter modules as requested. [3]

This adds the UAPI for the Asahi driver targeting the GPU in the Apple
M1 and M2 series systems on chip. The UAPI design is based on other
modern Vulkan-capable drivers, including Xe and Panthor. Memory
management is based on explicit VM management. Synchronization is
exclusively explicit sync.
This UAPI is validated against our open source Mesa stack, which is
fully conformant to the OpenGL 4.6, OpenGL ES 3.2, OpenCL 3.0, and
Vulkan 1.4 standards. The Vulkan driver supports sparse, exercising the
VM_BIND mechanism.
This patch adds the standalone UAPI header. It is implemented by an open
source DRM driver written in Rust. We fully intend to upstream this
driver when possible. However, as a production graphics driver, it
depends on a significant number of Rust abstractions that will take a
long time to upstream. In the mean time, our userspace is upstream in
Mesa but is not allowed to probe with upstream Mesa as the UAPI is not
yet reviewed and merged in the upstream kernel. Although we ship a
patched Mesa in Fedora Asahi Remix, any containers shipping upstream
Mesa builds are broken for our users, including upstream Flatpak and
Waydroid runtimes. Additionally, it forces us to maintain forks of Mesa
and virglrenderer, which complicates bisects.
The intention in sending out this patch is for this UAPI to be
thoroughly reviewed. Once we as the DRM community are satisfied with the
UAPI, this header lands signifying that the UAPI is stable and must only
be evolved in backwards-compatible ways; it will be the UAPI implemented
in the DRM driver that eventually lands upstream. That promise lets us
enable upstream Mesa, solving all these issues while the upstream Rust
abstractions are developed.
https://github.com/alyssarosenzweig/linux/commits/agx-uapi-v7 contains
the DRM driver implementing this proposed UAPI.
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/33984 contains
the Mesa patches to implement this proposed UAPI.
That Linux and Mesa branch together give a complete graphics/compute
stack on top of this UAPI.

Register a new driver(spi_amd_pci) for the HID2 SPI controller using the
PCI ID of the LPC bridge device.
Add a new common probe function in spi_amd driver to encapsulate the
code required for registering the controller driver. This function will be
utilized by both the existing ACPI driver and the newly introduced
PCI-based driver for the HID2 SPI controller. The MMIO register base
address of the HID2 SPI controller can be obtained from the PCI LPC bridge
registers.
By implementing these changes, the DMA buffer will be correctly associated
with the LPC bridge device, preventing IO_PAGE_FAULT caused by IOMMU when
the LPC bridge attempts DMA operations on addresses owned by the HID2
SPI controller.

Patch series "MAINTAINERS: add my isub-entries to MM part."
Following discussion at LSF/MM/BPF I'm adding execmem, secretmem and
numa memblocks sub-entries for MEMORY MANAGEMENT in MAINTAINERS.

Change title to "MEMORY MANAGEMENT - USERFAULTFD" and make it sub-topic in
memory management and add missing include/linux/userfaultfd_k.h and

Add an entry for userfaultfd and make myself a reviewer of it, just in
case it helps people manage the cc list.
I named it MEMORY USERFAULTFD, could be a bad name, but then it can be
together with the MEMORY* entries when everything is in alphabetic order,
which is definitely a benefit.
The line may not change much on how I'd work with userfaultfd; I think
I'll do the same as before.. But maybe it still, more or less, adds some
responsibility on top, indeed.
[akpm@linux-foundation.org: add include/linux/userfaultfd_k.h, per Mike]

subsystems for 6.15-rc1. Lots of stuff in here, including:
- loads of IIO changes and driver updates
- counter driver updates
- w1 driver updates
- faux conversions for some drivers that were abusing the platform bus
interface
- coresight driver updates
- rust miscdevice binding updates based on real-world-use

Uros Bizjak uses x86 named address space qualifiers to provide
compile-time checking of percpu area accesses.
This has caused a small amount of fallout - two or three issues were
reported. In all cases the calling code was founf to be incorrect.
- The 4 patch series "Some cleanup for memcg" from Chen Ridong
implements some relatively monir cleanups for the memcontrol code.
- The 17 patch series "mm: fixes for device-exclusive entries (hmm)"
from David Hildenbrand fixes a boatload of issues which David found then
using device-exclusive PTE entries when THP is enabled. More work is
needed, but this makes thins better - our own HMM selftests now succeed.
- The 2 patch series "mm: zswap: remove z3fold and zbud" from Yosry
Ahmed remove the z3fold and zbud implementations. They have been
deprecated for half a year and nobody has complained.
- The 5 patch series "mm: further simplify VMA merge operation" from
Lorenzo Stoakes implements numerous simplifications in this area. No
runtime effects are anticipated.
- The 4 patch series "mm/madvise: remove redundant mmap_lock operations
from process_madvise()" from SeongJae Park rationalizes the locking in
the madvise() implementation. Performance gains of 20-25% were observed
in one MADV_DONTNEED microbenchmark.

damos_walk() behaviors" from SeongJae Park fixes a few issues with the
accuracy of kdamond's walking of DAMON regions.
- The 3 patch series "expose mapping wrprotect, fix fb_defio use" from
Lorenzo Stoakes changes the interaction between framebuffer deferred-io
and core MM. No functional changes are anticipated - this is
preparatory work for the future removal of page structure fields.
- The 4 patch series "mm/damon: add support for hugepage_size DAMOS
filter" from Usama Arif adds a DAMOS filter which permits the filtering
by huge page sizes.
- The 4 patch series "mm: permit guard regions for file-backed/shmem
mappings" from Lorenzo Stoakes extends the guard region feature from its
present "anon mappings only" state. The feature now covers shmem and
file-backed mappings.
- The 4 patch series "mm: batched unmap lazyfree large folios during
reclamation" from Barry Song cleans up and speeds up the unmapping for
pte-mapped large folios.
- The 18 patch series "reimplement per-vma lock as a refcount" from
Suren Baghdasaryan puts the vm_lock back into the vma. Our reasons for
pulling it out were largely bogus and that change made the code more
messy. This patchset provides small (0-10%) improvements on one
microbenchmark.
- The 5 patch series "Docs/mm/damon: misc DAMOS filters documentation
fixes and improves" from SeongJae Park does some maintenance work on the
DAMON docs.

Senozhatsky teaches zram to run its compression and decompression
operations preemptibly.
- The 12 patch series "selftests/mm: Some cleanups from trying to run
them" from Brendan Jackman fixes a pile of unrelated issues which
Brendan encountered while runnimg our selftests.
- The 2 patch series "fs/proc/task_mmu: add guard region bit to pagemap"
from Lorenzo Stoakes permits userspace to use /proc/pid/pagemap to
determine whether a particular page is a guard page.
- The 7 patch series "mm, swap: remove swap slot cache" from Kairui Song
removes the swap slot cache from the allocation path - it simply wasn't
being effective.
- The 5 patch series "mm: cleanups for device-exclusive entries (hmm)"
from David Hildenbrand implements a number of unrelated cleanups in this
code.
- The 5 patch series "mm: Rework generic PTDUMP configs" from Anshuman
Khandual implements a number of preparatoty cleanups to the
GENERIC_PTDUMP Kconfig logic.

SeongJae Park implements a feedback-driven automatic tuning feature for
DAMON's aggregation interval tuning.
- The 5 patch series "Fix lazy mmu mode" from Ryan Roberts fixes some
issues in powerpc, sparc and x86 lazy MMU implementations. Ryan did
this in preparation for implementing lazy mmu mode for arm64 to optimize
vmalloc.

Shakeel Butt cleans up the page_counter code and fixes a size increase
which we accidentally added late last year.
- The 3 patch series "Add a command line option that enables control of
how many threads should be used to allocate huge pages" from Thomas
Prescher does that. It allows the careful operator to significantly
reduce boot time by tuning the parallalization of huge page
initialization.
- The 3 patch series "Fix calculations in trace_balance_dirty_pages()
for cgwb" from Tang Yizhou fixes the tracing output from the dirty page
balancing code.
- The 9 patch series "mm/damon: make allow filters after reject filters
useful and intuitive" from SeongJae Park improves the handling of allow
and reject filters. Behaviour is made more consistent and the
documention is updated accordingly.
- The 5 patch series "Switch zswap to object read/write APIs" from Yosry
Ahmed updates zswap to the new object read/write APIs and thus permits
the removal of some legacy code from zpool and zsmalloc.
- The 6 patch series "Some trivial cleanups for shmem" from Baolin Wang
does as it claims.

from Zi Yan reworks the code to split a folio into smaller folios. The
main benefit is lessened memory consumption: fewer post-split folios are
generated.
- The 2 patch series "Minimize xa_node allocation during xarry split"
from Zi Yan reduces the number of xarray xa_nodes which are generated
during an xarray split.

Unfortunately at some point I used another address and later copied it

Consistently use the dedicated address everywhere.
As the old address does in fact work, an update to mailmap is

Toolchain and infrastructure:
- Extract the 'pin-init' API from the 'kernel' crate and make it into
a standalone crate.
In order to do this, the contents are rearranged so that they can
easily be kept in sync with the version maintained out-of-tree that
other projects have started to use too (or plan to, like QEMU).
This will reduce the maintenance burden for Benno, who will now have
his own sub-tree, and will simplify future expected changes like the
move to use 'syn' to simplify the implementation.
- Add '#[test]'-like support based on KUnit.
We already had doctests support based on KUnit, which takes the
examples in our Rust documentation and runs them under KUnit.
Now, we are adding the beginning of the support for "normal" tests,
similar to those the '#[test]' tests in userspace Rust. For instance:
#[kunit_tests(my_suite)]
mod tests {
#[test]
fn my_test() {
assert_eq!(1 + 1, 2);
}
}
Unlike with doctests, the 'assert*!'s do not map to the KUnit
assertion APIs yet.
- Check Rust signatures at compile time for functions called from C by
name.
In particular, introduce a new '#[export]' macro that can be placed
in the Rust function definition. It will ensure that the function
declaration on the C side matches the signature on the Rust function:
#[export]
pub unsafe extern "C" fn my_function(a: u8, b: i32) -> usize {
// ...
}
The macro essentially forces the compiler to compare the types of
the actual Rust function and the 'bindgen'-processed C signature.
These cases are rare so far. In the future, we may consider
introducing another tool, 'cbindgen', to generate C headers
automatically. Even then, having these functions explicitly marked
may be a good idea anyway.
- Enable the 'raw_ref_op' Rust feature: it is already stable, and
allows us to use the new '&raw' syntax, avoiding a couple macros.
After everyone has migrated, we will disallow the macros.
- Pass the correct target to 'bindgen' on Usermode Linux.
- Fix 'rusttest' build in macOS.
'kernel' crate:
- New 'hrtimer' module: add support for setting up intrusive timers
without allocating when starting the timer. Add support for
'Pin<Box<_>>', 'Arc<_>', 'Pin<&_>' and 'Pin<&mut _>' as pointer types
for use with timer callbacks. Add support for setting clock source
and timer mode.
- New 'dma' module: add a simple DMA coherent allocator abstraction and
a test sample driver.
- 'list' module: make the linked list 'Cursor' point between elements,
rather than at an element, which is more convenient to us and allows
for cursors to empty lists; and document it with examples of how to
perform common operations with the provided methods.
- 'str' module: implement a few traits for 'BStr' as well as the
'strip_prefix()' method.
- 'sync' module: add 'Arc::as_ptr'.
- 'alloc' module: add 'Box::into_pin'.
- 'error' module: extend the 'Result' documentation, including a few
examples on different ways of handling errors, a warning about using
methods that may panic, and links to external documentation.
'macros' crate:
- 'module' macro: add the 'authors' key to support multiple authors.
The original key will be kept until everyone has migrated.
Documentation:
- Add error handling sections.
MAINTAINERS:
- Add Danilo Krummrich as reviewer of the Rust "subsystem".
- Add 'RUST [PIN-INIT]' entry with Benno Lossin as maintainer. It has
its own sub-tree.
- Add sub-tree for 'RUST [ALLOC]'.
- Add 'DMA MAPPING HELPERS DEVICE DRIVER API [RUST]' entry with Abdiel
Janulgue as primary maintainer. It will go through the sub-tree of

The changes have been on linux-next for at least 2 weeks, with the RCU

RCU change when KASAN + lockdep were enabled, but it was effectively

Merge tag 'bpf_res_spin_lock' of git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next
Pull bpf relisient spinlock support from Alexei Starovoitov:
"This patch set introduces Resilient Queued Spin Lock (or rqspinlock
with res_spin_lock() and res_spin_unlock() APIs).
This is a qspinlock variant which recovers the kernel from a stalled
state when the lock acquisition path cannot make forward progress.
This can occur when a lock acquisition attempt enters a deadlock
situation (e.g. AA, or ABBA), or more generally, when the owner of the
lock (which we’re trying to acquire) isn’t making forward progress.
Deadlock detection is the main mechanism used to provide instant
recovery, with the timeout mechanism acting as a final line of
defense. Detection is triggered immediately when beginning the waiting
loop of a lock slow path.
Additionally, BPF programs attached to different parts of the kernel
can introduce new control flow into the kernel, which increases the
likelihood of deadlocks in code not written to handle reentrancy.
There have been multiple syzbot reports surfacing deadlocks in
internal kernel code due to the diverse ways in which BPF programs can
be attached to different parts of the kernel. By switching the BPF
subsystem’s lock usage to rqspinlock, all of these issues are
mitigated at runtime.
This spin lock implementation allows BPF maps to become safer and
remove mechanisms that have fallen short in assuring safety when
nesting programs in arbitrary ways in the same context or across
different contexts.
We run benchmarks that stress locking scalability and perform
comparison against the baseline (qspinlock). For the rqspinlock case,
we replace the default qspinlock with it in the kernel, such that all
spin locks in the kernel use the rqspinlock slow path. As such,
benchmarks that stress kernel spin locks end up exercising rqspinlock.
More details in the cover letter in commit 6ffb9017e9 ("Merge branch
'resilient-queued-spin-lock'")"

fwctl is a new subsystem intended to bring some common rules and order to
the growing pattern of exposing a secure FW interface directly to
userspace. Unlike existing places like RDMA/DRM/VFIO/uacce that are
exposing a device for datapath operations fwctl is focused on debugging,
configuration and provisioning of the device. It will not have the
necessary features like interrupt delivery to support a datapath.
This concept is similar to the long standing practice in the "HW" RAID
space of having a device specific misc device to manage the RAID
controller FW. fwctl generalizes this notion of a companion debug and
management interface that goes along with a dataplane implemented in an
appropriate subsystem.
There have been three LWN articles written discussing various aspects of
this:
https://lwn.net/Articles/955001/https://lwn.net/Articles/969383/https://lwn.net/Articles/990802/
This pull requests includes three drivers to launch the subsystem:
- CXL provides a vendor scheme for executing commands and a way to learn
the 'command effects' (ie the security properties) of such
commands. The fwctl driver allows access to these mechanism within the
fwctl security model
- mlx5 is family of networking products, the driver supports all current
Mellanox HW still receiving FW feature updates. This includes RDMA
multiprotocol NICs like ConnectX and the Bluefield family of Smart
NICs.
- AMD/Pensando Distributed Services card is a multi protocol Smart NIC
with a multi PCI function design. fwctl works on the management PCI
function following a 'command effects' model similar to CXL.

Merge tag 'pci-v6.15-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Enable Configuration RRS SV, which makes device readiness visible,
early instead of during child bus scanning (Bjorn Helgaas)
- Log debug messages about reset methods being used (Bjorn Helgaas)
- Avoid reset when it has been disabled via sysfs (Nishanth
Aravamudan)
- Add common pci-ep-bus.yaml schema for exporting several peripherals
of a single PCI function via devicetree (Andrea della Porta)
- Create DT nodes for PCI host bridges to enable loading device tree
overlays to create platform devices for PCI devices that have
several features that require multiple drivers (Herve Codina)
Resource management:
- Enlarge devres table[] to accommodate bridge windows, ROM, IOV
BARs, etc., and validate BAR index in devres interfaces (Philipp
Stanner)
- Fix typo that repeatedly distributed resources to a bridge instead
of iterating over subordinate bridges, which resulted in too little
space to assign some BARs (Kai-Heng Feng)
- Relax bridge window tail sizing for optional resources, e.g., IOV
BARs, to avoid failures when removing and re-adding devices (Ilpo
Järvinen)
- Allow drivers to enable devices even if we haven't assigned
optional IOV resources to them (Ilpo Järvinen)
- Rework handling of optional resources (IOV BARs, ROMs) to reduce
failures if we can't allocate them (Ilpo Järvinen)
- Fix a NULL dereference in the SR-IOV VF creation error path (Shay
Drory)
- Fix s390 mmio_read/write syscalls, which didn't cause page faults
in some cases, which broke vfio-pci lazy mapping on first access
(Niklas Schnelle)
- Add pdev->non_mappable_bars to replace CONFIG_VFIO_PCI_MMAP, which
was disabled only for s390 (Niklas Schnelle)
- Support mmap of PCI resources on s390 except for ISM devices
(Niklas Schnelle)
ASPM:
- Delay pcie_link_state deallocation to avoid dangling pointers that
cause invalid references during hot-unplug (Daniel Stodden)
Power management:
- Allow PCI bridges to go to D3Hot when suspending on all non-x86
systems (Manivannan Sadhasivam)
Power control:
- Create pwrctrl devices in pci_scan_device() to make it more
symmetric with pci_pwrctrl_unregister() and make pwrctrl devices
for PCI bridges possible (Manivannan Sadhasivam)
- Unregister pwrctrl devices in pci_destroy_dev() so DOE, ASPM, etc.
can still access devices after pci_stop_dev() (Manivannan
Sadhasivam)
- If there's a pwrctrl device for a PCI device, skip scanning it
because the pwrctrl core will rescan the bus after the device is
powered on (Manivannan Sadhasivam)
- Add a pwrctrl driver for PCI slots based on voltage regulators
described via devicetree (Manivannan Sadhasivam)
Bandwidth control:
- Add set_pcie_speed.sh to TEST_PROGS to fix issue when executing the
set_pcie_cooling_state.sh test case (Yi Lai)
- Avoid a NULL pointer dereference when we run out of bus numbers to
assign for a bridge secondary bus (Lukas Wunner)
Hotplug:
- Drop superfluous pci_hotplug_slot_list, try_module_get() calls, and
NULL pointer checks (Lukas Wunner)
- Drop shpchp module init/exit logging, replace shpchp dbg() with
ctrl_dbg(), and remove unused dbg(), err(), info(), warn() wrappers
(Ilpo Järvinen)
- Drop 'shpchp_debug' module parameter in favor of standard dynamic
debugging (Ilpo Järvinen)
- Drop unused cpcihp .get_power(), .set_power() function pointers
(Guilherme Giacomo Simoes)
- Disable hotplug interrupts in portdrv only when pciehp is not
enabled to avoid issuing two hotplug commands too close together
(Feng Tang)
- Skip pciehp 'device replaced' check if the device has been removed
to address a deadlock when resuming after a device was removed
during system sleep (Lukas Wunner)
- Don't enable pciehp hotplug interupt when resuming in poll mode
(Ilpo Järvinen)
Virtualization:
- Fix bugs in 'pci=config_acs=' kernel command line parameter (Tushar
Dave)
DOE:
- Expose supported DOE features via sysfs (Alistair Francis)
- Allow DOE support to be enabled even if CXL isn't enabled (Alistair
Francis)
Endpoint framework:
- Convert PCI device data so pci-epf-test works correctly on
big-endian endpoint systems (Niklas Cassel)
- Add BAR_RESIZABLE type to endpoint framework and add DWC core
support for EPF drivers to set BAR_RESIZABLE type and size (Niklas
Cassel)
- Fix pci-epf-test double free that causes an oops if the host
reboots and PERST# deassertion restarts endpoint BAR allocation
(Christian Bruel)
- Fix endpoint BAR testing so tests can skip disabled BARs instead of
reporting them as failures (Niklas Cassel)
- Widen endpoint test BAR size variable to accommodate BARs larger
than INT_MAX (Niklas Cassel)
- Remove unused tools 'pci' build target left over after moving tests
to tools/testing/selftests/pci_endpoint (Jianfeng Liu)

first (Stanimir Varbanov)
- Expand inbound window map to 64GB so it can accommodate BCM2712
(Stanimir Varbanov)
- Add BCM2712 support and DT updates (Stanimir Varbanov)
- Apply link speed restriction before bringing link up, not after
(Jim Quinlan)
- Update Max Link Speed in Link Capabilities via the internal
writable register, not the read-only config register (Jim Quinlan)
- Handle regulator_bulk_get() error to avoid panic when we call
regulator_bulk_free() later (Jim Quinlan)
- Disable regulators only when removing the bus immediately below a
Root Port because we don't support regulators deeper in the
hierarchy (Jim Quinlan)
- Make const read-only arrays static (Colin Ian King)

- Correct MSG TLP generation so endpoints can generate INTx messages
(Hans Zhang)

input address (using parent_bus_offset) from devicetree (Frank Li)
Intel VMD host bridge driver:
- Convert vmd_dev.cfg_lock from spinlock_t to raw_spinlock_t so
pci_ops.read() will never sleep, even on PREEMPT_RT where
spinlock_t becomes a sleepable lock, to avoid calling a sleeping
function from invalid context (Ryo Takakura)
MediaTek PCIe Gen3 controller driver:
- Remove leftover mac_reset assert for Airoha EN7581 SoC (Lorenzo

via 'reg[config]' for host controllers and 'reg[addr_space]' for
endpoint controllers (Frank Li)

Merge tag 'drm-next-2025-03-28' of https://gitlab.freedesktop.org/drm/kernel
Pull drm updates from Dave Airlie:
"Outside of drm there are some rust patches from Danilo who maintains
that area in here, and some pieces for drm header check tests.
The major things in here are a new driver supporting the touchbar
displays on M1/M2, the nova-core stub driver which is just the vehicle
for adding rust abstractions and start developing a real driver inside
of.
xe adds support for SVM with a non-driver specific SVM core
abstraction that will hopefully be useful for other drivers, along
with support for shrinking for TTM devices. I'm sure xe and AMD
support new devices, but the pipeline depth on these things is hard to
know what they end up being in the marketplace!

This includes a major refactoring of the fbcon packed pixel drawing routines,
contributed by Zsolt Kajtar. The original version duplicated more or less the
same algorithms for both system and i/o memory. The new implementation is more
robust, both implementations are now feature complete (e.g. pixel order
reversing now supported by both), behaves the same way as it uses the identical
code for both variants and adds support for foreign endian framebuffers.
The other fixes and cleanups are:
- dummycon: only build module if there are users and fix rows/cols (Arnd Bergmann)
- mdacon: rework dependency list (Arnd Bergmann)
- lcdcfb, fsl-diu-fb, fbcon: Fix registering and removing of sysfs (Shixiong Ou)

- Add option traceoff_after_boot
In order to debug kernel boot, it sometimes is helpful to enable tracing
via the kernel command line. Unfortunately, by the time the login prompt
appears, the trace is overwritten by the init process and other user space
start up applications. Adding a "traceoff_after_boot" will disable tracing
when the kernel passes control to init which will allow developers to be
able to see the traces that occurred during boot.
- Clean up the mmflags macros that display the GFP flags in trace events
The macros to print the GFP flags for trace events had a bit of
duplication. The code was restructured to remove duplication and in the
process it also adds some flags that were missed before.
- Removed some dead code and scripts/draw_functrace.py
draw_functrace.py hasn't worked in years and as nobody complained
about it, remove it.
- Constify struct event_trigger_ops
The event_trigger_ops is just a structure that has function pointers that
are assigned when the variables are created. These variables should all be
constants.

There is new support for additional on-chip devices on Apple, Mediatek,
Renesas, Rockchip, Samsung, Google, TI, ST, Nvidia and Amlogic devices.
The Arm Morello reference platform gets a devicetree for booting in
normal aarch64 mode. The hardware supports experimental CHERI support,
which requires a modified kernel.
The AMD (formerly Xilinx) Versal NET SoC gets added, this is a combined
FPGA with Cortex-A78 CPUs in a SoC.
Six new ST STM32MP2 SoC variants are added. Like the earlier STM32MP25,
the MP211, MP213, MP215, MP231, MP233 and MP235 models are based on one
or two Cortex-A35 cores but each feature a different set of I/O devices.
Mediatek MT8370 is a minor variation of MT8390 with fewer CPU and
GPU cores
Apple T2 is the baseboard management controller on earlier Intel CPU
based Macs, with 16 models now gaining initial support.
All the above come with dts files for the reference boards. In
addition, these boards are added for the SoCs that are already supported.
- The Milk-V Jupiter board based on SpacemiT K1/M1
- NetCube Systems Kumquat board based on the 32-bit Allwinner V3s SoC
- Three boards based on 32-bit stm32mp1
- 11 distinct board variants from Toradex and one from Variscite,
all based on i.MX6
- Google Pixel Pro 6 phone based on gs101 (Tensor)
- Three additional variants of the i.MX8MP based "Skov" board

Core & protocols
----------------
- Continue Netlink conversions to per-namespace RTNL lock
(IPv4 routing, routing rules, routing next hops, ARP ioctls).
- Continue extending the use of netdev instance locks. As a driver
opt-in protect queue operations and (in due course) ethtool
operations with the instance lock and not RTNL lock.
- Support collecting TCP timestamps (data submitted, sent, acked)
in BPF, allowing for transparent (to the application) and lower
overhead tracking of TCP RPC performance.
- Tweak existing networking Rx zero-copy infra to support zero-copy
Rx via io_uring.
- Optimize MPTCP performance in single subflow mode by 29%.
- Enable GRO on packets which went thru XDP CPU redirect (were queued
for processing on a different CPU). Improving TCP stream performance
up to 2x.
- Improve performance of contended connect() by 200% by searching
for an available 4-tuple under RCU rather than a spin lock.
Bring an additional 229% improvement by tweaking hash distribution.
- Avoid unconditionally touching sk_tsflags on RX, improving
performance under UDP flood by as much as 10%.
- Avoid skb_clone() dance in ping_rcv() to improve performance under
ping flood.
- Avoid FIB lookup in netfilter if socket is available, 20% perf win.
- Rework network device creation (in-kernel) API to more clearly
identify network namespaces and their roles.
There are up to 4 namespace roles but we used to have just 2 netns
pointer arguments, interpreted differently based on context.
- Use sysfs_break_active_protection() instead of trylock to avoid
deadlocks between unregistering objects and sysfs access.
- Add a new sysctl and sockopt for capping max retransmit timeout
in TCP.
- Support masking port and DSCP in routing rule matches.
- Support dumping IPv4 multicast addresses with RTM_GETMULTICAST.
- Support specifying at what time packet should be sent on AF_XDP
sockets.
- Expose TCP ULP diagnostic info (for TLS and MPTCP) to non-admin users.
- Add Netlink YAML spec for WiFi (nl80211) and conntrack.
- Introduce EXPORT_IPV6_MOD() and EXPORT_IPV6_MOD_GPL() for symbols
which only need to be exported when IPv6 support is built as a module.
- Age FDB entries based on Rx not Tx traffic in VxLAN, similar
to normal bridging.
- Allow users to specify source port range for GENEVE tunnels.
- netconsole: allow attaching kernel release, CPU ID and task name
to messages as metadata
Driver API
----------

* Move vm_table members out of kernel/sysctl.c
All vm_table array members have moved to their respective subsystems leading
to the removal of vm_table from kernel/sysctl.c. This increases modularity by
placing the ctl_tables closer to where they are actually used and at the same
time reducing the chances of merge conflicts in kernel/sysctl.c.
* ctl_table range fixes
Replace the proc_handler function that checks variable ranges in
coredump_sysctls and vdso_table with the one that actually uses the extra{1,2}
pointers as min/max values. This tightens the range of the values that users
can pass into the kernel effectively preventing {under,over}flows.
* Misc fixes
Correct grammar errors and typos in test messages. Update sysctl files in
MAINTAINERS. Constified and removed array size in declaration for
alignment_tbl
* Testing
- These have all been in linux-next for at least 1 month
- They have gone through 0-day
- Ran all these through sysctl selftests in x86_64

Merge tag 'sysctl-6.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl
Pull sysctl updates from Joel Granados:
- Move vm_table members out of kernel/sysctl.c
All vm_table array members have moved to their respective subsystems
leading to the removal of vm_table from kernel/sysctl.c. This
increases modularity by placing the ctl_tables closer to where they
are actually used and at the same time reducing the chances of merge
conflicts in kernel/sysctl.c.
- ctl_table range fixes
Replace the proc_handler function that checks variable ranges in
coredump_sysctls and vdso_table with the one that actually uses the
extra{1,2} pointers as min/max values. This tightens the range of the
values that users can pass into the kernel effectively preventing
{under,over}flows.
- Misc fixes
Correct grammar errors and typos in test messages. Update sysctl
files in MAINTAINERS. Constified and removed array size in
declaration for alignment_tbl

Updates to the usual drivers (scsi_debug, ufs, lpfc, st, fnic, mpi3mr,

is an addition to unit attention handling to recognize UAs for power
on/reset and new media so the tape driver can use it.

Merge tag 'for-6.15/io_uring-20250322' of git://git.kernel.dk/linux
Pull io_uring updates from Jens Axboe:
"This is the first of the io_uring pull requests for the 6.15 merge
window, there will be others once the net tree has gone in. This
contains:
- Cleanup and unification of cancelation handling across various
request types.
- Improvement for bundles, supporting them both for incrementally
consumed buffers, and for non-multishot requests.
- Enable toggling of using iowait while waiting on io_uring events or
not. Unfortunately this is still tied with CPU frequency boosting
on short waits, as the scheduler side has not been very receptive
to splitting the (useless) iowait stat from the cpufreq implied
boost.
- Add support for kbuf nodes, enabling zero-copy support for the ublk
block driver.
- Various cleanups for resource node handling.
- Series greatly cleaning up the legacy provided (non-ring based)
buffers. For years, we've been pushing the ring provided buffers as
the way to go, and that is what people have been using. Reduce the
complexity and code associated with legacy provided buffers.
- Series cleaning up the compat handling.
- Series improving and cleaning up the recvmsg/sendmsg iovec and msg
handling.
- Series of cleanups for io-wq.
- Start adding a bunch of selftests. The liburing repository
generally carries feature and regression tests for everything, but
at least for ublk initially, we'll try and go the route of having
it in selftests as well. We'll see how this goes, might decide to
migrate more tests this way in the future.
- Various little cleanups and fixes"

We've received lots of commits at this time, as a result of various
cleanup and refactoring works as well as a few new drivers and the
generic SoundWire support. Most of changes are device-specific,
little about the core changes. Some highlights below:
Core:
* A couple of (rather minor) race fixes in ALSA sequencer code
* A regression fix in ALSA timer code that may lead to a deadlock
ASoC:
* A large series of code conversion to use modern terminology for the
clocking configuration
* Conversions of PM ops with the modern macros in all ASoC drivers
* Clarification of the control operations
* Prepartory work for more generic SoundWire SCDA controls
* Support for AMD ACP 7.x, AWINC WM88166, Everest ES8388, Intel AVS
PEAKVOL and GAIN DSP modules Mediatek MT8188 DMIC, NXP i.MX95,
nVidia Tegra interconnects, Rockchip RK3588 S/PDIF, Texas
Instruments SN012776 and TAS5770L, and Wolfson WM8904 DMICs
Others:
* Conversions of PM ops with the modern macros in the rest drivers
* USB-audio quirks and fixes for Presonus Studio, DJM-A9, CME
* HD-audio quirks and fixes ASUS, HP, Lenovo, and others
Note that the PR contains some changes from the tip tree for AMD code,
and it might give some merge conflict due to the rebase afterwards.

This patch series is focused on improving the compatibility and usability of the
hid-pidff force feedback driver. Last patch introduces a new, universal driver
for PID devices that need some special handling like report fixups, remapping the
button range, managing new pidff quirks and setting desirable fuzz/flat values.
This work has been done in the span of the past months with the help of the great
Linux simracing community, with a little input from sim flight fans from FFBeast.
No changes interfere with compliant and currently working PID devices.
"Generic" codepath was tested as well with Moza and Simxperience AccuForce v2.
I'm not married to the name. It's what we used previously, but if "universal" is
confusing (pidff is already the generic driver), we can come up with something
better like "hid-quirky-pidff" :)
With v8 and tiny finx in v9, all the outstanding issues were resolved,
additional pidff issues were fixed and hid-pidff defines moved to a dedicated
header file. This patch series could be considered done bar any comments and
requests from input maintainers.
I could save more then a dozen lines of code by changing simple if statements
to only occupy on line instead of two in there's a need for that.
* New
- Support ACPI match for Framework systems.

The biggest change for SPI this release is the addition of offload
support from David Lechner, allowing the hardware to trigger SPI
transactions autonomously. The initial use case is for triggering IIO
operations but there are other applications where having the hardware
ready to go at a minimal signal is useful for synchronising with
external inputs (eg, interrupt handling) or reducing latency (eg, CAN
networking). Otherwise there's the usual fixes, improvements and
cleanups, plus support for a bunch of new devices.
- Support for offloaing support from David Lechner.
- Support for GOcontrol1 Moduline modules, Mediatek MT7988, NXP i.MX94,
Qualcomm SPI NAMD, Rockchip RK3562, Sophogo SG2044 and ST STM32 OSPI.

Another set of improvements to the kernel's CRC (cyclic redundancy
check) code:
- Rework the CRC64 library functions to be directly optimized, like what
I did last cycle for the CRC32 and CRC-T10DIF library functions.
- Rewrite the x86 PCLMULQDQ-optimized CRC code, and add VPCLMULQDQ
support and acceleration for crc64_be and crc64_nvme.
- Rewrite the riscv Zbc-optimized CRC code, and add acceleration for
crc_t10dif, crc64_be, and crc64_nvme.
- Remove crc_t10dif and crc64_rocksoft from the crypto API, since they
are no longer needed there.
- Rename crc64_rocksoft to crc64_nvme, as the old name was incorrect.
- Add kunit test cases for crc64_nvme and crc7.
- Eliminate redundant functions for calculating the Castagnoli CRC32,
settling on just crc32c().
- Remove unnecessary prompts from some of the CRC kconfig options.
- Further optimize the x86 crc32c code.

Pull lsm updates from Paul Moore:
- Various minor updates to the LSM Rust bindings
Changes include marking trivial Rust bindings as inlines and comment
tweaks to better reflect the LSM hooks.
- Add LSM/SELinux access controls to io_uring_allowed()
Similar to the io_uring_disabled sysctl, add a LSM hook to
io_uring_allowed() to enable LSMs a simple way to enforce security
policy on the use of io_uring. This pull request includes SELinux
support for this new control using the io_uring/allowed permission.
- Remove an unused parameter from the security_perf_event_open() hook
The perf_event_attr struct parameter was not used by any currently
supported LSMs, remove it from the hook.
- Add an explicit MAINTAINERS entry for the credentials code
We've seen problems in the past where patches to the credentials code
sent by non-maintainers would often languish on the lists for
multiple months as there was no one explicitly tasked with the
responsibility of reviewing and/or merging credentials related code.
Considering that most of the code under security/ has a vested
interest in ensuring that the credentials code is well maintained,
I'm volunteering to look after the credentials code and Serge Hallyn
has also volunteered to step up as an official reviewer. I posted the
MAINTAINERS update as a RFC to LKML in hopes that someone else would
jump up with an "I'll do it!", but beyond Serge it was all crickets.
- Update Stephen Smalley's old email address to prevent confusion
This includes a corresponding update to the mailmap file.

Pull power management updates from Rafael Wysocki:
"These are dominated by cpufreq updates which in turn are dominated by
updates related to boost support in the core and drivers and
amd-pstate driver optimizations.
Apart from the above, there are some cpuidle updates including a
rework of the most recent idle intervals handling in the venerable
menu governor that leads to significant improvements in some
performance benchmarks, as the governor is now more likely to predict
a shorter idle duration in some cases, and there are updates of the
core device power management code, mostly related to system suspend
and resume, that should help to avoid potential issues arising when
the drivers of devices depending on one another want to use different
optimizations.
There is also a usual collection of assorted fixes and cleanups,
including removal of some unused code.

- Consolidate the VDSO storage
The VDSO data storage and data layout has been largely architecture
specific for historical reasons. That increases the maintenance effort
and causes inconsistencies over and over.
There is no real technical reason for architecture specific layouts and
implementations. The architecture specific details can easily be
integrated into a generic layout, which also reduces the amount of
duplicated code for managing the mappings.
Convert all architectures over to a unified layout and common mapping
infrastructure. This splits the VDSO data layout into subsystem
specific blocks, timekeeping, random and architecture parts, which
provides a better structure and allows to improve and update the
functionalities without conflict and interaction.
- Rework the timekeeping data storage
The current implementation is designed for exposing system timekeeping
accessors, which was good enough at the time when it was designed.
PTP and Time Sensitive Networking (TSN) change that as there are
requirements to expose independent PTP clocks, which are not related to
system timekeeping.
Replace the monolithic data storage by a structured layout, which
allows to add support for independent PTP clocks on top while reusing
both the data structures and the time accessor implementations.

This also ensures that myself and the x86-cpuid mailing list are CCed on

Merge Energy Model handling code updates and updates of the runtime PM
core code for 6.15-rc1:
- Clean up the Energy Model handling code somewhat (Rafael Wysocki).
- Use kfree_rcu() to simplify the handling of runtime Energy Model
updates (Li RongQing).
- Add an entry for the Energy Model framework to MAINTAINERS as
properly maintained (Lukasz Luba).
- Address RCU-related sparse warnings in the Energy Model code (Rafael
Wysocki).
- Remove ENERGY_MODEL dependency on SMP and allow it to be selected
when DEVFREQ is set without CPUFREQ so it can be used on a wider
range of systems (Jeson Gao).
- Unify error handling during runtime suspend and runtime resume in the
core to help drivers to implement more consistent runtime PM error
handling (Rafael Wysocki).
- Drop a redundant check from pm_runtime_force_resume() and rearrange
documentation related to __pm_runtime_disable() (Rafael Wysocki).
* pm-em:
PM: EM: Rework the depends on for CONFIG_ENERGY_MODEL
PM: EM: Address RCU-related sparse warnings
PM: EM: Consify two parameters of em_dev_register_perf_domain()
MAINTAINERS: Add Energy Model framework as properly maintained

Merge cpuidle updates for 6.15-rc5, including a menu governor update
that is reported to improve some benchmark results quite significantly:
- Update the handling of the most recent idle intervals in the menu
cpuidle governor to prevent useful information from being discarded
by it in some cases and improve the prediction accuracy (Rafael
Wysocki).
- Make it possible to tell the intel_idle driver to ignore its built-in
table of idle states for the given processor, clean up the handling
of auto-demotion disabling on Baytrail and Cherrytrail chips in it,
and update its MAINTAINERS entry (David Arcari, Artem Bityutskiy,
Rafael Wysocki).
- Make some cpuidle drivers use for_each_present_cpu() instead of
for_each_possible_cpu() during initialization to avoid issues
occurring when nosmp or maxcpus=0 are used (Jacky Bai).
* pm-cpuidle:
cpuidle: Init cpuidle only for present CPUs
cpuidle: intel_idle: Update MAINTAINERS
intel_idle: introduce 'no_native' module parameter
cpuidle: menu: Update documentation after get_typical_interval() changes

Some Turris devices support signing messages with a per-device unique
asymmetric key that was created on the device at manufacture time.
Add helper module that helps to expose this ability via the keyctl()
syscall.
A device-specific driver can register a signing key by calling
devm_turris_signing_key_create().
Both the `.turris-signing-keys` keyring and the signing key are created
with only the VIEW, READ and SEARCH permissions for userspace - it is
impossible to link / unlink / move them, set their attributes, or unlink
the keyring from userspace.

Merge series from Francesco Dolcini <francesco@dolcini.it>:
This patch series adds DMIC and DRC support to the WM8904 driver, a new
of_ helper is added to simplify the driver code.
DRC functionality is added in the same patch series to provide the
necessary dynamic range control to make DMIC support useful.
The WM8904 supports digital microphones on two of its inputs:
IN1L/DMICDAT1 and IN1R/DMICDAT2. These two inputs can either be
connected to an ADC or to the DMIC system. There is an ADC for each
line, and only one DMIC block. This DMIC block is either connected to
DMICDAT1 or to DMICDAT2. One DMIC data line supports two digital
microphones via time multiplexing.
The pin's functionality is decided during hardware design (IN1L vs
DMICDAT1 and IN1R vs DMICDAT2). This is reflected in the Device Tree.
If one line is analog and one is DMIC, we need to be able to switch
between ADC and DMIC at runtime. The DMIC source is known from the
Device Tree. If both are DMIC inputs, we need to be able to switch the
DMIC source. There is no need to switch between ADC and DMIC at runtime.
Therefore, kcontrols are dynamically added by the driver depending on
its Device Tree configuration.
This is a heavy rework of a previous patch series provided by Alifer
Moraes and Pierluigi Passaro,
https://lore.kernel.org/lkml/20220307141041.27538-1-alifer.m@variscite.com.
The National Instruments (NI) 16550 is a 16550-like UART with larger
FIFOs and embedded RS-232/RS-485 transceiver control circuitry. This
patch adds a driver that can operate this UART, which is used for
onboard serial ports in several NI embedded controller designs.
Portions of this driver were originally written by Jaeden Amero and
Karthik Manamcheri, with extensive cleanups and refactors since by
Brenda Streiff.

Add a new procedural macro (`#[kunit_tests(kunit_test_suit_name)]`) to
run KUnit tests using a user-space like syntax.
The macro, that should be used on modules, transforms every `#[test]`
in a `kunit_case!` and adds a `kunit_unsafe_test_suite!` registering
all of them.
The only difference with user-space tests is that instead of using
`#[cfg(test)]`, `#[kunit_tests(kunit_test_suit_name)]` is used.
Note that `#[cfg(CONFIG_KUNIT)]` is added so the test module is not
compiled when `CONFIG_KUNIT` is set to `n`.

supported newer IP blocks - USI v2 - present in Exynos850 and newer.
A bit older ARM64 designs, like Exynos8895 use older USI v1 block.
2. Add Exynos ACPM (Alive Clock and Power Manager) protocol driver
for Google GS101 SoC. ACPM protocol allows communication between the
power management firmware and other embedded processors.
3. Exynos2200: Add PMU, ChipID and SYSREG Devicetree bindings.
4. Exynos7870: Add PMU and ChipID Devicetree bindings.
5. Various cleanups.

The zbud compressed pages allocator is rarely used, most users use
zsmalloc. zbud consumes much more memory (only stores 1 or 2 compressed
pages per physical page). The only advantage of zbud is a marginal
performance improvement that by no means justify the memory overhead.
Historically, zsmalloc had significantly worse latency than zbud and
z3fold but offered better memory savings. This is no longer the case as
shown by a simple recent analysis [1]. In a kernel build test on tmpfs in
a limited cgroup, zbud 2-3% less time than zsmalloc, but at the cost of
using ~32% more memory (1.5G vs 1.13G). The tradeoff does not make sense
for zbud in any practical scenario.
The only alleged advantage of zbud is not having the dependency on
CONFIG_MMU, but CONFIG_SWAP already depends on CONFIG_MMU anyway, and zbud
is only used by zswap.
Remove zbud after z3fold's removal, leaving zsmalloc as the one and only
zpool allocator. Leave the removal of the zpool API (and its associated
config options) to a followup cleanup after no more allocators show up.
Deprecating zbud for a few cycles before removing it was initially
proposed [2], like z3fold was marked as deprecated for 2 cycles [3].
However, Johannes rightfully pointed out that the 2 cycles is too short
for most downstream consumers, and z3fold was deprecated first only as a
courtesy anyway.

Kernel build commands can sometimes be long, particularly when
cross-compiling, making them tedious to type and prone to mistypes.
This commit introduces bash completion support for common variables
and targets in Kbuild.
For installation instructions, please refer to the documentation in
Documentation/kbuild/bash-completion.rst.
The following examples demonstrate how this saves typing.
[Example 1] a long command line for cross-compiling
$ make A<TAB>
-> completes 'A' to 'ARCH='
$ make ARCH=<TAB>
-> displays all supported architectures
$ make ARCH=arm64 CR<TAB>
-> completes 'CR' to 'CROSS_COMPILE='
$ make ARCH=arm64 CROSS_COMPILE=<TAB>
-> displays installed toolchains
$ make ARCH=arm64 CROSS_COMPILE=aa<TAB>
-> completes 'CROSS_COMPILE=aa' to 'CROSS_COMPILE=aarch64-linux-gnu-'
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- def<TAB>
-> completes 'def' to 'defconfig'
[Example 2] a single build target
$ make f<TAB>
-> completes 'f' to 'fs/'
$ make fs/<TAB>
-> displays objects and sub-directories in fs/
$ make fs/xf<TAB>
-> completes 'fs/xf' to 'fs/xfs/'
$ make fs/xfs/l<TAB>
-> completes 'fs/xfs/l' to 'fs/xfs/libxfs/xfs_'
$ make fs/xfs/libxfs/xfs_g<TAB>
-> completes 'fs/xfs/libxfs/xfs_g' to 'fs/xfs/libxfs/xfs_group.o'
This does not aim to provide a complete list of variables and targets,
as there are too many. However, it covers variables and targets used
in common scenarios, and I hope this is useful enough.

Herbert asks for long-term maintenance of everything under
crypto/asymmetric_keys/ and associated algorithms (ECDSA, GOST, RSA) [1].
Ignat has kindly agreed to co-maintain this with me going forward.
Stefan has agreed to be added as reviewer for ECDSA. He introduced it
in 2021 and has been meticulously providing reviews for 3rd party
patches anyway.
Retain David Howells' maintainer entry until he explicitly requests to
be removed. He originally introduced asymmetric keys in 2012.
RSA was introduced by Tadeusz Struk as an employee of Intel in 2015,
but he's changed jobs and last contributed to the implementation in 2016.
GOST was introduced by Vitaly Chikunov as an employee of Basealt LLC [2]
(Базальт СПО [3]) in 2019. This company is an OFAC sanctioned entity
[4][5], which makes employees ineligible as maintainer [6]. It's not
clear if Vitaly is still working for Basealt, he did not immediately
respond to my e-mail. Since knowledge and use of GOST algorithms is
relatively limited outside the Russian Federation, assign "Odd fixes"
status for now.

Recently the ZSTD tree has been removed from linux-next due to lack of
updates for last year [1]. As there are several users of ZSTD in kernel
we need to keep the code maintained and updated. I'll act as a backup to
get the ZSTD upstream to linux, Nick is OK with that [2].

The usual mixture of new drivers, support in existing drivers for new
devices, a range of features and general subsystem cleanup.
Two merges of immutable branches in here:
* SPI offload support. Culmination of a long effort to bring the ability
to offload triggered sequences of SPI operations to specific hardware,
allow high datarate acquisition over an SPI bus (if you have the right
hardware / FPGA firmware)
* GPIO set-array-helper - enables code simplification.

AD4855, AD4846, AD4857, AD4858 and AD4858I high speed multichannel
simultaneous sampling ADCs.

it maps to IIO.
core
- New description for FAULT events, used in the ad7173.
- filter_type ABI used in ad4130.

Cleanup and minor bug fixes
===========================
Tree wide:
- Stop using iio_device_claim_direct_scoped() and introduce sparse friendly
iio_device_claim/release_direct()
The conditional scoped cleanup has proved hard to deal with, requiring
workarounds for various compiler issues and in is rather non-intuitive
so abandon that experiment. One of the attractions of that approach was
that it made it much harder to have unbalanced claim/release bugs so
instead introduce a conditional-lock style boolean returning new pair
of functions. These are inline in the header and have __acquire and
__release calls allowing sparse to detect lack of balance. There are
occasional false positives but so far those have reflected complex code
paths that benefited from cleanup anyway.
The first set of driver conversions are in this pull request, more to
follow next cycle. Various related cleanup in drivers.
Removal of the _scoped code is completed and the definition removed.
- Use of str_enable_disable() and similar helpers.
- Don't set regmap cache to REGCACHE_NONE as that's the default anyway.
- Change some caches from RBTREE to MAPLE reflecting best practice.
- Use the new gpiod_multi_set_value_cansleep()
- Make sure to grab direct mode for some calibrations paths.
- Avoid using memcmp on structures when checking for matching channel configs.
Instead just match field by field.
dt-bindings:
- Fix up indentation inconsistencies.
gts-helper:
- Simplify building of available scale table.
adi,ad-sigma-delta
- Make sure to disable channel after calibration done.
- Add error handling in configuring channel during calibration.
adi,ad2s1201
- use a bitmap_write() rather than directly accessing underlying storage.
adi,ad3552r-hs
- Fix a wrong error message.
- Make sure to use instruction mode for configuration.
adi,ad4695
- Add a conversion to ensure exit from conversion mode.
- Use custom regmap to handle required sclk rate change.
- Fix an out of bounds array access
- Simplify oversampling ratio handling.
adi,ad4851
- Fix a sign bug.
adi,ad5791
- Fix wrong exported number of storage bits.
adi,ad7124
- Disable all channels at probe to avoid strange initial configurations.
adi,ad7173
- Rework to allow static const struct ad_sigma_delta without need
to make a copy.
adi,ad7623
- Drop a BSD license tag that the authors consider unnecessary.
adi,ad7768-1
- Fix channels sign description exposed to user space.
- Set MOSI idle state to avoid accidental device reset.

The T-Head TH1520 SoC contains multiple power islands that can be
programmatically turned on and off using the AON (Always-On) protocol
and a hardware mailbox [1]. The relevant mailbox driver has already been
merged into the mainline kernel in commit 5d4d263e1c ("mailbox:
Introduce support for T-head TH1520 Mailbox driver");
Introduce a power-domain driver for the TH1520 SoC, which is using AON
firmware protocol to communicate with E902 core through the hardware
mailbox. This way it can send power on/off commands to the E902 core.
The interaction with AUDIO power island e.g trying to turn it OFF proved
to crash the firmware running on the E902 core. Introduce the workaround
to disable interacting with the power island.

The T-Head TH1520 SoC uses an E902 co-processor running Always-On (AON)
firmware to manage power, clock, and other system resources [1]. This
patch introduces a driver implementing the AON firmware protocol,
allowing the Linux kernel to communicate with the firmware via mailbox
channels. Through an RPC-based interface, the kernel can initiate power
state transitions, update resource configurations, and perform other
AON-related tasks.

When resctrl is fully factored into core and per-arch code, each arch will
need to use some resctrl common definitions in order to define its own
specializations and helpers. Following conventional practice, it would be
desirable to put the dependent arch definitions in an <asm/resctrl.h> header
that is included by the common <linux/resctrl.h> header. However, this can
make it awkward to avoid a circular dependency between <linux/resctrl.h> and
the arch header.
To avoid such dependencies, move the affected common types and constants into
a new header that does not need to depend on <linux/resctrl.h> or on the arch
headers.
The same logic applies to the monitor-configuration defines, move these too.
Some kind of enumeration for events is needed between the filesystem and
architecture code. Take the x86 definition as its convenient for x86.
The definition of enum resctrl_event_id is needed to allow the architecture
code to define resctrl_arch_mon_ctx_alloc() and resctrl_arch_mon_ctx_free().
The definition of enum resctrl_res_level is needed to allow the architecture
code to define resctrl_arch_set_cdp_enabled() and
resctrl_arch_get_cdp_enabled().
The bits for mbm_local_bytes_config et al are ABI, and must be the same on all
architectures. These are documented in Documentation/arch/x86/resctrl.rst
The maintainers entry for these headers was missed when resctrl.h was created.
Add a wildcard entry to match both resctrl.h and resctrl_types.h.

Add the initial documentation of the Nova project.
The initial project documentation consists out of a brief introduction
of the project, as well as project guidelines both general and nova-core
specific and a task list for nova-core specifically.
The task list is divided into tasks for general Rust infrastructure
required by the project, tasks regarding GSP enablement and firmware
abstraction, general GPU driver tasks as well as tasks related to
external API design and test infrastructure.

Add the initial nova-core driver stub.
nova-core is intended to serve as a common base for nova-drm (the
corresponding DRM driver) and the vGPU manager VFIO driver, serving as a
hard- and firmware abstraction layer for GSP-based NVIDIA GPUs.
The Nova project, including nova-core and nova-drm, in the long term,
is intended to serve as the successor of Nouveau for all GSP-based GPUs.
The motivation for both, starting a successor project for Nouveau and
doing so using the Rust programming language, is documented in detail
through a previous post on the mailing list [1], an LWN article [2] and a
talk from LPC '24.
In order to avoid the chicken and egg problem to require a user to
upstream Rust abstractions, but at the same time require the Rust
abstractions to implement the driver, nova-core kicks off as a driver
stub and is subsequently developed upstream.

The lack of an explicit credential (kernel/cred.c) entry has caused
confusion in the past among new, and not-so-new developers, about where
to send credential patches for discussion and merging. Those patches
that are sent can often rot on the mailing lists for months as there
is no clear maintainer tasked with reviewing and merging patches.
I'm volunteering for the cred maintainer role to try and reduce the
confusion and help cred patches find their way up to Linus' tree. As
there generally aren't a lot of cred patches I'll start with simply
folding them into the LSM tree, but if this changes I'll setup a

He is primarily working on the Nova GPU driver [1][2].
In addition, he has been active in the mailing list and most recently
submitted the Device / Driver PCI / Platform series.
He is also already a maintainer of `RUST [ALLOC]` as well as several
other DRM-related entries.
His expertise developing Rust abstractions and APIs for one of the major
users of Rust in the kernel will be very useful to have around in the
future. Thus add him to the `RUST` entry as reviewer.

mlx5 FW has a built in security context called UID. Each UID has a set of
permissions controlled by the kernel when it is created and every command
is tagged by the kernel with a particular UID. In general commands cannot
reach objects outside of their UID and commands cannot exceed their UID's
permissions. These restrictions are enforced by FW.
This mechanism has long been used in RDMA for the devx interface where
RDMA will sent commands directly to the FW and the UID limitations
restrict those commands to a ib_device/verbs security domain. For instance
commands that would effect other VFs, or global device resources. The
model is suitable for unprivileged userspace to operate the RDMA
functionality.
The UID has been extended with a "tools resources" permission which allows
additional commands and sub-commands that are intended to match with the
scope limitations set in FWCTL. This is an alternative design to the
"command intent log" where the FW does the enforcement rather than having
the FW report the enforcement the kernel should do.
Consistent with the fwctl definitions the "tools resources" security
context is limited to the FWCTL_RPC_CONFIGURATION,
FWCTL_RPC_DEBUG_READ_ONLY, FWCTL_RPC_DEBUG_WRITE, and
FWCTL_RPC_DEBUG_WRITE_FULL security scopes.
Like RDMA devx, each opened fwctl file descriptor will get a unique UID
associated with each file descriptor.
The fwctl driver is kept simple and we reject commands that can create
objects as the UID mechanism relies on the kernel to track and destroy
objects prior to detroying the UID. Filtering into fwctl sub scopes is
done inside the driver with a switch statement. This substantially limits
what is possible to primarily query functions ad a few limited set
operations.
mlx5 already has a robust infrastructure for delivering RPC messages to
fw. Trivially connect fwctl's RPC mechanism to mlx5_cmd_do(). Enforce the
User Context ID in every RPC header accepted from the FD so the FW knows
the security context of the issuing ID.

Each file descriptor gets a chunk of per-FD driver specific context that
allows the driver to attach a device specific struct to. The core code
takes care of the memory lifetime for this structure.
The ioctl dispatch and design is based on what was built for iommufd. The
ioctls have a struct which has a combined in/out behavior with a typical
'zero pad' scheme for future extension and backwards compatibility.
Like iommufd some shared logic does most of the ioctl marshaling and
compatibility work and table dispatches to some function pointers for
each unique ioctl.
This approach has proven to work quite well in the iommufd and rdma
subsystems.
Allocate an ioctl number space for the subsystem.

Create the class, character device and functions for a fwctl driver to

A typical fwctl driver has a sysfs presence like:
$ ls -l /dev/fwctl/fwctl0

$ ls /sys/class/fwctl/fwctl0

$ ls /sys/devices/pci0000:00/0000:00:0a.0/fwctl/fwctl0

Which allows userspace to link all the multi-subsystem driver components
together and learn the subsystem specific names for the device's

The main and bulk of the addition this time is the support for the Arm
reference Morello System Development Platform (SDP).
The Morello architecture is an experimental extension to Armv8.2-A,
enhancing the AArch64 execution state with capabilities for fine-grained
memory protection and scalable software compartmentalization. However
these changes doesn't add any of the support for security enhancements.
This is mainly adding device tree support for Morello SDP.
The platform iteslf is shipped with ACPI firmware. However, since the
ACPI bindings for GPU, DPU, I2C, I2S,..etc are not well defined or not
provided in the shipped ACPI firmware, there is a need for the device
tree as alternative for the developers focusing on those features.
The CPU is called rainier, the architecture is Morello and the platform
is Morello SDP board. There is FVP equivalent of the same though they
are not completely in feature parity with the real hardware.
These changes provide the initial support for Morello SDP and FVP
platforms.
Apart from this, we have an update to add support for secondary cores
on Corstone1000 FVP platform.

Merge tag 'juno-updates-6.15' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/dt
Armv8 FVP/Vexpress/Juno updates for v6.15
The main and bulk of the addition this time is the support for the Arm
reference Morello System Development Platform (SDP).
The Morello architecture is an experimental extension to Armv8.2-A,
enhancing the AArch64 execution state with capabilities for fine-grained
memory protection and scalable software compartmentalization. However
these changes doesn't add any of the support for security enhancements.
This is mainly adding device tree support for Morello SDP.
The platform iteslf is shipped with ACPI firmware. However, since the
ACPI bindings for GPU, DPU, I2C, I2S,..etc are not well defined or not
provided in the shipped ACPI firmware, there is a need for the device
tree as alternative for the developers focusing on those features.
The CPU is called rainier, the architecture is Morello and the platform
is Morello SDP board. There is FVP equivalent of the same though they
are not completely in feature parity with the real hardware.
These changes provide the initial support for Morello SDP and FVP
platforms.
Apart from this, we have an update to add support for secondary cores
on Corstone1000 FVP platform.

- Enables the host to access specific SoC registers through the PMC
firmware using IPC commands. This access method is necessary for
registers that are not available through direct Memory-Mapped I/O (MMIO),
which is used for other accessible parts of the PMC.

Merge series from patrice.chotard@foss.st.com:
This series adds SPI NOR support for STM32MP25 SoCs from STMicroelectronics.
On STM32MP25 SoCs family, an Octo Memory Manager block manages the muxing,
the memory area split, the chip select override and the time constraint
between its 2 Octo SPI children.
Due to these depedencies, this series adds support for:
- Octo Memory Manager driver (not applied for SPI).
- Octo SPI driver.
- yaml schema for Octo Memory Manager and Octo SPI drivers.
The device tree files adds Octo Memory Manager and its 2 associated Octo
SPI chidren in stm32mp251.dtsi and adds SPI NOR support in stm32mp257f-ev1
board.
Move the common DWC struct definitions, which are shared across all the
DesginWare PCIe IPs, to a new header file called 'pcie-dwc.h', so that
other users e.g., debugfs, perf and sysfs can make use of them.

The Touch Bars found on x86 Macs support two USB configurations: one
where the device presents itself as a HID keyboard and can display
predefined sets of keys, and one where the operating system has full
control over what is displayed.
This commit adds support for the display functionality of the second
configuration. Functionality for the first configuration has been
merged in the HID tree.
Note that this driver has only been tested on T2 Macs, and only includes
the USB device ID for these devices. Testing on T1 Macs would be
appreciated.
Credit goes to Ben (Bingxing) Wang on GitHub for reverse engineering
most of the protocol.
Also, as requested by Andy, I would like to clarify the use of __packed
structs in this driver:
- All the packed structs are aligned except for appletbdrm_msg_information.
- We have to pack appletbdrm_msg_information since it is requirement of
the protocol.
- We compared binaries compiled by keeping the rest structs __packed and
not __packed using bloat-o-meter, and __packed was not affecting code
generation.
- To maintain consistency, rest structs have been kept __packed.
I would also like to point out that since the driver was reverse-engineered
the actual data types of the protocol might be different, including, but
not limited to, endianness.

There are three variants of which Huawei released the first two
simultaneously.
Huawei Matebook E Go LTE(sc8180x), codename seems to be gaokun2.
Huawei Matebook E Go(sc8280xp@3.0GHz), codename must be gaokun3. (see [1])
Huawei Matebook E Go 2023(sc8280xp@2.69GHz), codename should be also gaokun3.
Adding support for the latter two variants for now, this driver should
also work for the sc8180x variant according to acpi table files, but I
don't have the device to test yet.
Different from other Qualcomm Snapdragon sc8280xp based machines, the
Huawei Matebook E Go uses an embedded controller while others use
a system called PMIC GLink. This embedded controller can be used to
perform a set of various functions, including, but not limited to:
- Battery and charger monitoring;
- Charge control and smart charge;
- Fn_lock settings;
- Tablet lid status;
- Temperature sensors;
- USB Type-C notifications (ports orientation, DP alt mode HPD);
- USB Type-C PD (according to observation, up to 48w).
Add a driver for the EC which creates devices for UCSI and power supply
devices.
This driver is inspired by the following drivers:
drivers/platform/arm64/acer-aspire1-ec.c
drivers/platform/arm64/lenovo-yoga-c630.c
drivers/platform/x86/huawei-wmi.c
Also thanks for reviewers' working. They have made this patch improve
a lot.

The object size sanity checking macros that uaccess.h and uio.h use
have been living in thread_info.h for historical reasons. Needing to
use jump labels for these checks, however, introduces a header include
loop under certain conditions. The dependencies for the object checking
macros are very limited, but they are used by separate header files,
so introduce a new header that can be used directly by uaccess.h and
uio.h. As a result, this also means thread_info.h (which is rather large)
and be removed from those headers.

This entry enumerates bitmap and related APIs listed in BITMAP API entry
that rust requires but cannot use directly (i.e. inlined functions and
macros).
The "Rust kernel policy" (https://rust-for-linux.com/rust-kernel-policy)
document describes the special status of rust support:
"Exceptionally, for Rust, a subsystem may allow to temporarily
break Rust code."
Accordingly, the following policy applies to all interfaces under the
BITMAP API entry that are used in rust codebase, including those not
listed explicitly here.
Bitmap developers do their best to keep the API stable. When API or
user-visible behavior needs to be changed such that it breaks rust,
bitmap and rust developers collaborate as follows:
- bitmap developers don't consider rust bindings as a blocker for the
API change;
- bindings maintainer (me) makes sure that kernel build doesn't break
with CONFIG_RUST=y. This implies fixes in the binding layer, but not
in rust codebase;
- rust developers adopt new version of API in their codebase and remove
unused bindings timely.
