- support for new firmware handling in intel-ish-hid (Vishnu Sankar)
|
|
Introduce a mechanism for managing global kernel state whose lifecycle is
tied to the preservation of one or more files. This is necessary for
subsystems where multiple preserved file descriptors depend on a single,
shared underlying resource.
An example is HugeTLB, where multiple file descriptors such as memfd and
guest_memfd may rely on the state of a single HugeTLB subsystem.
Preserving this state for each individual file would be redundant and
incorrect. The state should be preserved only once when the first file is
preserved, and restored/finished only once the last file is handled.
This patch introduces File-Lifecycle-Bound (FLB) objects to solve this
problem. An FLB is a global, reference-counted object with a defined set
of operations:
- A file handler (struct liveupdate_file_handler) declares a dependency
on one or more FLBs via a new registration function,
liveupdate_register_flb().
- When the first file depending on an FLB is preserved, the FLB's
.preserve() callback is invoked to save the shared global state. The
reference count is then incremented for each subsequent file.
- Conversely, when the last file is unpreserved (before reboot) or
finished (after reboot), the FLB's .unpreserve() or .finish() callback
is invoked to clean up the global resource.
The implementation includes:
- A new set of ABI definitions (luo_flb_ser, luo_flb_head_ser) and a
corresponding FDT node (luo-flb) to serialize the state of all active
FLBs and pass them via Kexec Handover.
- Core logic in luo_flb.c to manage FLB registration, reference
counting, and the invocation of lifecycle callbacks.
- An API (liveupdate_flb_get/_incoming/_outgoing) for other kernel
subsystems to safely access the live object managed by an FLB, both
before and after the live update.
This framework provides the necessary infrastructure for more complex
subsystems like IOMMU, VFIO, and KVM to integrate with the Live Update
Orchestrator.

Patch series "list private v2 & luo flb", v9.
This series introduces two connected infrastructure improvements: a new
API for handling private linked lists, and the "File-Lifecycle-Bound"
(FLB) mechanism for the Live Update Orchestrator.
1. Private List Primitives (patches 1-3)
Recently, Linux introduced the ability to mark structure members as
__private and access them via ACCESS_PRIVATE(). This enforces better
encapsulation by ensuring internal details are only accessible by the
owning subsystem.
However, struct list_head is frequently used as an internal linkage
mechanism within these private sections. The standard macros in
<linux/list.h> do not support ACCESS_PRIVATE() natively. Consequently,
subsystems using private lists are forced to implement ad-hoc
workarounds or local iterator macros.
This series adds <linux/list_private.h>, providing a set of
primitives identical to those in <linux/list.h> but designed for
private list heads. It also includes a KUnit test suite to verify that
the macros correctly handle pointer offsets and qualifiers.
2. This series adds FLB (patches 4-5) support to Live Update that also
internally uses private lists.
FLB allows global kernel state (such as IOMMU domains or HugeTLB
state) to be preserved once, shared across multiple file descriptors,
and restored when needed. This is necessary for subsystems where
multiple preserved file descriptors depend on a single, shared
underlying resource. Preserving this state for each individual file
would be redundant and incorrect.
FLB uses reference counting tied to the lifecycle of preserved
files. The state is preserved when the first file depending on it is
preserved, and restored or cleaned up only when the last file is
handled.
This patch (of 5):
Linux recently added an ability to add private members to structs (i.e.
__private) and access them via ACCESS_PRIVATE(). This ensures that those
members are only accessible by the subsystem which owns the struct type,
and not to the object owner.
However, struct list_head often needs to be placed into the private
section to be manipulated privately by the subsystem.
Add macros to support private list manipulations in
<linux/list_private.h>.

Add a new module parameter 'panic_on_stall_time' that triggers a panic
when a workqueue stall persists for longer than the specified duration
in seconds.
Unlike 'panic_on_stall' which counts accumulated stall events, this
parameter triggers based on the duration of a single continuous stall.
This is useful for catching truly stuck workqueues rather than
accumulating transient stalls.
Usage:
workqueue.panic_on_stall_time=120
This would panic if any workqueue pool has been stalled for 120 seconds
or more.
The stall duration is measured from the workqueue last progress
(poll_ts) which accounts for legitimate system stalls.

This is a USB HID device which includes an I2C controller and 8 GPIO pins.
The binding allows describing the chip's gpio and i2c controller in DT,
with the i2c controller being bound to a subnode named "i2c". This is
intended to be used in configurations where the CP2112 is permanently
connected in hardware.

Add new compatible string 'fsl,imx952-asrc' for i.MX952 platform,
below are the differences that make this ASRC not fallback compatible
with other platforms.
1) There is a power domain on i.MX952 for the wakeupmix system where
ASRC is in. But it is enabled by default, ASRC device don't need
to enable it, so it is optional for i.MX952.
2) The clock sources of ASRC are different on i.MX952.
3) There is a limitation on i.MX952 that DMA request is not cleared at the
end of conversion with dma slave mode. Which causes sample is dropped from
the input fifo on the second time if DMA is triggered before the client
device and DMA may copy wrong data from output fifo as the output fifo is
not ready in the beginning. So there is specially handling in the driver.

Add errata section with code examples for querying errata and a warning
that most applications should not check errata. Use kernel-doc directives
to include errata descriptions from the header files instead of manual
links.
Also enhance existing DOC sections in security/landlock/errata/abi-*.h
files with Impact sections, and update the code comment in syscalls.c
to remind developers to update errata documentation when applicable.
This addresses the gap where the kernel implements errata tracking
but provides no user-facing documentation on how to use it, while
improving the existing technical documentation in-place rather than
duplicating it.

Add documentation for LANDLOCK_RESTRICT_SELF_TSYNC. It does not need to go
into the main example, but it has a section in the ABI compatibility notes.
In the HTML rendering, the main reference is the system call documentation,
which is included from the landlock.h header file.

The boot integrity attribute represents that the CPU or APU is used for the
hardware root of trust in the boot process. This bit only represents the
CPU/APU and some vendors have other hardware root of trust implementations
specific to their designs.

Merge series from "Miquel Raynal (Schneider Electric)" <miquel.raynal@bootlin.com>:
This series adds support for the QSPI controller available on Renesas
RZ/N1S and RZ/N1D SoC. It has been tested with a custom board (see last
SPI patch for details), but has been tested by Wolfram (thank you!) on
the DB board.
Link: https://lore.kernel.org/linux-devicetree/20260116114852.52948-2-wsa+renesas@sang-engineering.com/
Adding support for this SoC required a few adaptations to the Cadence
QSPI driver which have already been merged (except one regarding clocks
handling). This series contains the remaining patches, the ones actually
adding support for the RZ/N1 flavour.

Add support for the Renesas RZ/N1D400 QSPI controller.
This SoC is identified in the bindings with its other name: r9a06g032.
It is part of the RZ/N1 family, which contains a "D" and a "S"
variant. IPs in this SoC are typically described using 2 compatibles:
the SoC specific compatible and the family compatible. The original
Cadence IP compatible is dropped because it is unusable on its own.
Indirect accesses are not supported by this flavour of the Cadence IP,
which means several properties have no meaning in the scope of the
Renesas compatible. Let's make sure they are no longer expected nor
mandatory.

Terminate the value search for a key if it hits a newline and make
the value empty.
When we pass a bootconfig with an empty value terminated by the
newline, like below::
foo =
bar = value
Current bootconfig interprets it as a single entry::
foo = "bar = value";
The Documentation/admin-guide/bootconfig.rst defines the value
itself is terminated by newline:
The value has to be terminated by semi-colon (``;``) or newline (``\n``).
but it does not define when the value search is terminated.
This changes the behavior to be more line-oriented, so that it is
clearer in how it works.
- The value search of key-value pair will be terminated by a comment
or newline.
- The value search of an array will continue beyond comments and
newlines.
Thus, with this update, the above example is interpreted as::
foo = "";
bar = "value";
And the below example will cause a syntax error because "bar" is expected
as a key but it has ','.
foo =
bar, buz
According to this change, one wrong example config is updated.

The S32 chipsets have a GPR region which has a miscellaneous registers
including the GMAC_0_CTRL_STS register. Originally, this code accessed
that register in a sort of ad-hoc way, but it's cleaner to use a
syscon interface to access these registers.
We still need to maintain the old method of accessing the GMAC register
but using a syscon will let us access other registers more cleanly.

Merge series from Sen Wang <sen@ti.com>:
This series adds asynchronous mode support to the McASP driver, which
enables independent configuration of bitclocks, frame sync, and audio
configurations between tx(playback) and rx(record). And achieves
simultaneous playback & record using different audio configurations.
It also adds two clean up patches to the McASP driver that disambiguate
and simplifies the logic which avoids the async enhancement from being
too convoluted to review and analyze.
The implementation is based on vendor documentation and patches tested in
both SK-AM62P-LP (sync mode, McASP slave) and AM62D-EVM
(async mode, McASP master, rx & tx has different TDM configs).
Testing verifies async mode functionality while maintaining backward
compatibility with the default sync mode.
Bootlog and Async mode tests on AM62D-EVM: [0]

Merge series from André Draszik <andre.draszik@linaro.org>:
This series extends the existing S2MPG10 PMIC driver to add support for
the regulators, and adds new S2MPG11 core and regulator drivers.
The patches are kept together in one series, due to S2MPG11 and its
regulators being very similar to S2MPG10.
The Samsung S2MPG11 PMIC is a Power Management IC for mobile
applications with buck converters, various LDOs, power meters, and
additional GPIO interfaces. It typically complements an S2MPG10 PMIC in
a main/sub configuration as the sub-PMIC and both are used on the
Google Pixel 6 and 6 Pro (oriole / raven).
A DT update for Oriole / Raven to enable these is required which I will
send out separately.

McASP supports the independent configuration of TX & RX clk and frame
sync registers. By default, the driver is configured in synchronous mode
where RX clock generator is disabled and it uses transmit clock signals as
bit clock and frame sync. Therefore add optional properties needed for
asynchronous mode.
Add ti,async-mode boolean binding to provide a way to decouple the default
behavior and allows for independent TX & RX clocking.
Add tdm-slots-rx uint32 binding to provide an alternative hardware
specifier stating the number of RX serializers.
The existing property tdm-slots will still dictate number of
TX serializers, and RX if tdm-slots-rx isn't given for backwards
compatibility.
Add auxclk-fs-ratio-rx which allows to specify the ratio just for RX.
The driver can be supplied with two different ratios
(auxclk-fs-ratio and auxclk-fs-ratio-rx in tandem) and achieve two
different sampling rates for tx & rx.
