this is a pull request of 22 patches for net-next/main.
The series by Biju Das contains 19 patches and adds RZ/G3E CANFD
support to the rcar_canfd driver.
The patch by Vincent Mailhol adds a struct data_bittiming_params to
group FD parameters as a preparation patch for CAN-XL support.
Felix Maurer's patch imports tst-filter from can-tests into the kernel
self tests and Vincent Mailhol adds support for physical CAN
interfaces.

sec_irq_init() is an internal API for the core driver, and doesn't
belong into the public header.
Due to an upcoming split of the driver into a core and i2c driver,
we'll also be adding more internal APIs, which again shouldn't be in
the public header.
Move it into a new internal include.

Currently kernel/fork.c both contains absolutely key logic relating to a
number of kernel subsystems and also has absolutely no assignment in
MAINTAINERS.
Correct this by placing this file in relevant sections - mm core, exec and
the scheduler so people know who to contact when making changes here.
scripts/get_maintainers.pl can perfectly well handle a file being in
multiple sections, so this functions correctly.
Intent is that we keep putting changes to kernel/fork.c through Andrew's
tree.

The changes in this release are quite large, mainly in drivers rather
than the core. This is partly due to cleanups that touch a lot of
drivers and partly due to several relatively large new drivers.
- Support for automatically enumerating DAIs from standards conforming
SoundWire SDCA devices, further work is required for these to be
useful in an actual card.

Merge tag 'asoc-v6.16' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for v6.16
The changes in this release are quite large, mainly in drivers rather
than the core. This is partly due to cleanups that touch a lot of
drivers and partly due to several relatively large new drivers.
- Support for automatically enumerating DAIs from standards conforming
SoundWire SDCA devices, further work is required for these to be
useful in an actual card.
- Conversion of quite a few drivers to newer GPIO APIs.
- More helpers and cleanups from Mormimoto-san.
- Support for a wider range of AVS platforms.
- Support for AMD ACP 7.x platforms, Cirrus Logic CS35L63 and CS48L32,
Everest Semiconductor ES8389, Longsoon-1 AC'97 controllers, nVidia
Tegra264, Richtek ALC203 and RT9123 and Rockchip SAI controllers.
Cross-merge networking fixes after downstream PR (net-6.15-rc8).

Note - last minute rebase was to drop a typo patch that I'd accidentally
picked up (in the microblaze arch Kconfig)
Take 2 is due to that rebase messing up some fixes tags that were
referring to patches after that point.
There is a known merge conflict due to changes in neighbouring lines.
Stephen's resolution in linux-next is:
https://lore.kernel.org/linux-next/20250506155728.65605bae@canb.auug.org.au/
Added 3 named IIO reviewers to MAINTAINERS. This is a reflection of those
who have been doing much of this work for some time. Lars-Peter is
removed from the entry having moved on to other topics. Thanks
Nuno, David and Andy for stepping up and Lars-Peter for all your
hard work in the past!
Includes the usual mix of new device support, features and general
cleanup.
This time we also have some tree wide changes.
- Rip out the iio_device_claim_direct_scoped() as it proved hard to work
with. This series includes quite a few related cleanups such as use
of guard or factoring code out to allow direct returns.
- Switch from iio_device_claim/release_direct_mode() to new
iio_device_claim/release_direct() which is structured so that sparse
can warn on failed releases. There were a few false positives but
those were mostly in code that benefited from being cleaned up as part
of this process.
- Introduce iio_push_to_buffers_with_ts() to replace the _timestamp()
version over time. This version takes the size of the supplied buffer
which the core checks is at least as big as expected by calculation
from channel descriptions of those channels enabled. Use this in
an initial set of drivers.
- Add macros for IIO_DECLARE_BUFFER_WITH_TS() and
IIO_DECLARE_DMA_BUFFER_WITH_TS() to avoid lots of fiddly code to ensure
correctly aligned buffers for timestamps being added onto the end of
channel data.
New device support
------------------
adi,ad3530r
- New driver for AD3530, AD3530R, AD3531 and AD3531R DACs with
programmable gain controls. R variants have internal references.

- Support ad7606c-16 and ad7606c-18 devices. Includes switch to dynamic
channel information allocation.
adi,ad7380
- Add support for the AD7389-4

- New driver for this oxygen sensor.
mediatek,mt2701-auxadc
- Add binding for MT6893 which is fully compatible with already supported
MT8173.
meson-saradc
- Support the GXLX SoCs. Mostly this is a workaround for some unrelated
clock control bits found in the ADC register map.
nuvoton,nct7201
- New driver for NCT7201 and NCT7202 I2C ADCs.
rohm,bd79124

functionality of the already supported bd79703. Included making this
driver suitable for support device variants.
st,stm32-lptimer
- Add support for stm32pm25 to this trigger.
Features
--------
Beyond IIO

Previously these could be read only.
- Helper library that should avoid code duplication for simpler ADC
bindings that have a child node per channel.
- Enforce that IIO_DMA_MINALIGN is always at least 8 (almost always true
and simplifies code on all significant architectures)
core/backend
- Add support to control source of data - useful when the HDL includes
things like generated ramps for testing purposes. Enable this for
adi-axi-dac
adi,ad3552-hs
- Add debugfs related callbacks to allow debug access to register contents.
adi,ad4000
- Support SPI offload with appropriate FPGA firmware along with improving
documentation.
adi,ad7293
- Add support for external reference voltage.
adi,ad7606
- Support SPI offload.

- Support filter frequencies beyond 2^32.
adi,adxl345
- Add single and double tap events.
hid-sensor-prox
- Support 16-bit report sizes as seen on some Intel platforms.
invensense,icm42600
- Enable use of named interrupts to avoid problems with some wiring choices.
Get the interrupt by name, but fallback to previous assumption on the first
being INT1 if no names are supplied.
microchip,mcp3911
- Add reset gpio support.
rohm,bh7150
- Add reset gpio support.
st,stm32
- Add support to control oversampling.
ti,adc128s052
- Add support for ROHM BD79104 which is early compatible with the TI
parts already supported by this driver. Includes some general driver
cleanup and a separate dt binding.
- Simplify reference voltage handling by assuming it is fixed after enabling
the supply.
winsen,mhz19b
- New driver for this C02 sensor.
Cleanup and minor fixes
-----------------------
dt-bindings
- Correct indentation and style for DTS examples.
- Use unevalutateProperties for SPI devices instead of additionalProperties
to allow generic SPI properties from spi-peripheral-props.yaml
ABI Docs
- Add missing docs for sampling_frequency when it applies only to events.
Treewide
- Various minor tweaks, comment fixes and similar.
- Sort TI ADCs in Kconfig that had gotten out of order.
- Switch various drives that provide GPIO chip functionality to the new
callbacks with return values.
- Standardize on { } formatting for all array sentinels.
- Make use of aligned_s64 in a few places to replace either wrong types
or manually defined equivalents.
- Drop places where spi bits_per_word is set to 8 because that is the
default anyway.
adi,ad_sigma_delta library
- Avoid a potential use of uninitialized data if reg_size has a value
that is not supported (no drivers hit this but it is reasonable hardening)
adi,ad4030
- Add error checking for scan types and no longer store it in state.
- Rework code to reduce duplication.
- Move setting the mode from buffer preenable() to update_scan_mode(),
better matching expected semantics of the two different callbacks.
- Improve data marshalling comments.
adi,ad4695
- Use u16 for buffer elements as oversampling is not yet supported except
with SPI offload (which doesn't use this path).
adi,ad5592r
- Clean up destruction of mutexes.
- Use lock guards to simplify code (later patch fixes a missed unlock)
adi,ad5933
- Correct some incorrect settling times.
adi,ad7091
- Deduplicate handling of writable vs volatile registers as they are the
inverse of each other for this device.
adi,ad7124
- Fix 3db Filter frequency.
- Remove ability to directly write the filter frequency (which was broken)
- Register naming improvements.
adi,ad7606
- Add a missing return value check.
- Fill in max sampling rates for all chips.
- Use devm_mutex_init()
- Fix up some kernel-doc formatting issues.
- Remove some camel case that snuck in.
- Drop setting address field in channels as easily established from other
fields.

adi,ad9832
- Add of_device_id table rather than just relying on fallbacks.
- Use FIELD_PREP() to set values of fields.
adi,admv1013
- Cleanup a pointless ternary.
adi,admv8818
- Fix up LPF Band 5 frequency which was slightly wrong.
- Fix an integer overflow.
- Fix range calculation
adi,adt7316
- Replace irqd_get_trigger_type(irq_get_irq_data()) with simpler
irq_get_trigger_type()
adi,adxl345
- Use regmap cache instead of various state variables that were there to
reduce bus accesses.
- Make regmap return value checking consistent across all call sites.
adi,axi-dac
- Add a check on number of channels (0 to 15 valid)
allwinner,sun20i
- Use new adc-helpers to replace local parsing code for channel nodes.
bosch,bmp290
- Move to local variables for sensor data marshalling removing the need
for a messy definition that has to work for all supported parts.
Follow up fix adds a missing initialization.
dynaimage,al3010 and dynaimage,al3320a
- Various minor cleanup to bring these drivers inline with reviewed feedback
given on a new driver.
- Fix an error path in which power down is not called when it should be.

- Deduplicate code for setting up interrupts.
microchip,mcp3911
- Fix handling of conversion results register which differs across supported
devices.
idt,zopt2201

inverse of writeable registers on this device.
renesas,rzg2l
- Use new adc-helpers to replace local parsing code for channel nodes.
ti,ads1298
- Fix a missing Kconfig dependency.

The TPS61310/TPS61311 is a flash LED driver with I2C interface. Its power
stage is capable of supplying a maximum total current of roughly 1500mA.
The TPS6131x provides three constant-current sinks, capable of sinking up
to 2 x 400mA (LED1 and LED3) and 800mA (LED2) in flash mode. In torch mode
each sink (LED1, LED2, LED3) supports currents up to 175mA.

This is [1/3] part of hinic3 Ethernet driver initial submission.
With this patch hinic3 is a valid kernel module but non-functional
driver.
The driver parts contained in this patch:
Module initialization.
PCI driver registration but with empty id_table.
Auxiliary driver registration.
Net device_ops registration but open/stop are empty stubs.
tx/rx logic.
All major data structures of the driver are fully introduced with the
code that uses them but without their initialization code that requires
management interface with the hw.

Add support for Aeonsemi AS21xxx 10G C45 PHYs. These PHYs integrate
an IPC to setup some configuration and require special handling to
sync with the parity bit. The parity bit is a way the IPC use to
follow correct order of command sent.
Supported PHYs AS21011JB1, AS21011PB1, AS21010JB1, AS21010PB1,
AS21511JB1, AS21511PB1, AS21510JB1, AS21510PB1, AS21210JB1,
AS21210PB1 that all register with the PHY ID 0x7500 0x7510
before the firmware is loaded.
They all support up to 5 LEDs with various HW mode supported.
While implementing it was found some strange coincidence with using the
same logic for implementing C22 in MMD regs in Broadcom PHYs.
For reference here the AS21xxx PHY name logic:
AS21x1xxB1

Tests for the can subsystem have been in the can-tests repository[1] so
far. Start moving the tests to kernel selftests by importing the current
tst-filter test. The test is now named test_raw_filter and is substantially
updated to be more aligned with the kernel selftests, follow the coding
style, and simplify the validation of received CAN frames. We also include
documentation of the test design. The test verifies that the single filters
on raw CAN sockets work as expected.
We intend to import more tests from can-tests and add additional test cases
in the future. The goal of moving the CAN selftests into the tree is to
align the tests more closely with the kernel, improve testing of CAN in
general, and to simplify running the tests automatically in the various
kernel CI systems.

programmable gain controls, providing full-scale output spans of 2.5V or
5V for reference voltages of 2.5V. These devices operate from a single
2.7V to 5.5V supply and are guaranteed monotonic by design. The "R"
variants include a 2.5V, 5ppm/°C internal reference, which is disabled
by default.

====================
ovpn: pull request for net-next: ovpn 2025-05-15
this is a new version of the previous pull request.
These time I have removed the fixes that we are still discussing,
so that we don't hold the entire series back.
There is a new fix though: it's about properly checking the return value
of skb_to_sgvec_nomark(). I spotted the issue while testing pings larger
than the iface's MTU on a TCP VPN connection.
I have added various Closes and Link tags where applicable, so
that we have references to GitHub tickets and other public discussions.
Since I have resent the PR, I have also added Andrew's Reviewed-by to
the first patch.
Please pull or let me know if something should be changed!

Non-trivial C macros and inlined C functions cannot be used directly
in the Rust code and are used via functions ("helpers") that wrap
those so that they can be called from Rust.

Current driver uses static LMTST region allocated by firmware.
Firmware allocated memory for LMTST is available in PF/VF BAR2.
Using this memory have performance impact as this is mapped as
device memory. There is another option to allocate contiguous
memory at run time and map this in LMT MAP table with the
help of AF driver. With this patch dynamic allocated memory
is used for LMTST.

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.

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

5. PTM Context update

Merge tag 'ib-mfd-gpio-nvmem-v6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd into gpio/for-next
Immutable branch between MFD, GPIO and NVMEM due for the v6.16 merge window
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.

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.

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

├── 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.

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.

Adds a driver for the ITE Embedded Controller (EC) on Portwell boards.
It integrates with the Linux GPIO and watchdog subsystems to provide:
- Control/monitoring of up to 8 EC GPIO pins.
- Hardware watchdog timer with 1-255 second timeouts.
The driver communicates with the EC via I/O port 0xe300 and identifies
the hardware by the "PWG" firmware signature. This enables enhanced
system management for Portwell embedded/industrial platforms.

The TUXEDO Sirius 16 Gen1 and TUXEDO Sirius 16 Gen2 devices have a per-key
controllable RGB keyboard backlight. The firmware API for it is implemented
via WMI.
To make the backlight userspace configurable this driver emulates a
LampArray HID device and translates the input from hidraw to the
corresponding WMI calls. This is a new approach as the leds subsystem lacks
a suitable UAPI for per-key keyboard backlights, and like this no new UAPI
needs to be established.
The handle_* functions an corresponding structs are named based on the HID
spec: HID Usage Tables 1.6 -> 26 Lighting And Illumination Page (0x59)

Introduce a driver for devices running Dasharo firmware. The driver
supports thermal monitoring using a new ACPI interface in Dasharo. The
initial version supports monitoring fan speeds, fan PWM duty cycles and
system temperatures as well as determining which specific interfaces are
implemented by firmware.
It has been tested on a NovaCustom laptop running pre-release Dasharo
firmware, which implements fan and thermal monitoring for the CPU and
the discrete GPU, if present.

In preparation for creating a new drivers/virt/coco/host/ directory to
house shared host driver infrastructure for confidential computing, move
configfs-tsm to a guest/ sub-directory. The tsm.ko module is renamed to
tsm_reports.ko. The old tsm.ko module was only ever demand loaded by
kernel internal dependencies, so it should not affect existing userspace
module install scripts.
The new drivers/virt/coco/guest/ is also a preparatory landing spot for

Before extending the driver with functions from the R-Car ISP core that
will span multiple files move the existing driver to a separate
directory. While at it rename the single source file to allow future
files to be grouped by functions.

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.

Merge series from Olivier Moysan <olivier.moysan@foss.st.com>:
This patchset adds some checks on kernel minimum rate requirements.
This avoids potential clock rate misconfiguration, when setting the
kernel frequency on STM32MP2 SoCs.
