The cxlctl_validate_set_features() function is type bool. It's supposed
to return true for valid requests and false for invalid. However, this
error path returns ERR_PTR(-EINVAL) which is true when it was intended to
return false.
The incorrect return will result in kernel failing to prevent a
incorrect op_size passed in from userspace to be detected.

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace
and kernelspace coding, or when dealing with uapi headers that
rather should use __ASSEMBLER__ instead. So let's standardize on
the __ASSEMBLER__ macro that is provided by the compilers now.
This is a completely mechanical patch (done with a simple "sed -i"
statement).

__ASSEMBLY__ is only defined by the Makefile of the kernel, so
this is not really useful for uapi headers (unless the userspace
Makefile defines it, too). Let's switch to __ASSEMBLER__ which

The custom swap function used in sort() was identical to the default
built-in sort swap. Remove the custom swap function and passes NULL to
sort(), allowing it to use the default swap function.
This change reduces code size and improves performance, particularly when
CONFIG_MITIGATION_RETPOLINE is enabled. With RETPOLINE mitigation, indirect
function calls incur significant overhead, and using the default swap
function avoids this cost.

The core atomic code has a number of macros where it elaborates
architecture primitives into more functions. ARC uses
arch_atomic64_cmpxchg() as it's architecture primitive which disable alot
of the additional functions.
Instead provide arch_cmpxchg64_relaxed() as the primitive and rely on the
core macros to create arch_cmpxchg64().
The macros will also provide other functions, for instance,
try_cmpxchg64_release(), giving a more complete implementation.

Improve the installation procedure for the systemd service unit
'cpupower.service', to be more flexible. Some distros install libraries
to /usr/lib64/, but systemd service units have to be installed to
/usr/lib/systemd/system: as a consequence, the installation procedure
should not assume that systemd service units can be installed to
${libdir}/systemd/system ...
Define a dedicated variable ("unitdir") in the Makefile.

When FRED is enabled, if the Trap Flag (TF) is set without an external
debugger attached, it can lead to an infinite loop in the SIGTRAP
handler. To avoid this, the software event flag in the augmented SS
must be cleared, ensuring that no single-step trap remains pending when
ERETU completes.
This test checks for that specific scenario—verifying whether the kernel
correctly prevents an infinite SIGTRAP loop in this edge case when FRED
is enabled.
The test should _always_ pass with IDT event delivery, thus no need to
disable the test even when FRED is not enabled.

SIGTRAP handler
Clear the software event flag in the augmented SS to prevent immediate
repeat of single step trap on return from SIGTRAP handler if the trap
flag (TF) is set without an external debugger attached.
Following is a typical single-stepping flow for a user process:
1) The user process is prepared for single-stepping by setting
RFLAGS.TF = 1.
2) When any instruction in user space completes, a #DB is triggered.
3) The kernel handles the #DB and returns to user space, invoking the
SIGTRAP handler with RFLAGS.TF = 0.
4) After the SIGTRAP handler finishes, the user process performs a
sigreturn syscall, restoring the original state, including
RFLAGS.TF = 1.
5) Goto step 2.
According to the FRED specification:
A) Bit 17 in the augmented SS is designated as the software event
flag, which is set to 1 for FRED event delivery of SYSCALL,
SYSENTER, or INT n.
B) If bit 17 of the augmented SS is 1 and ERETU would result in
RFLAGS.TF = 1, a single-step trap will be pending upon completion
of ERETU.
In step 4) above, the software event flag is set upon the sigreturn
syscall, and its corresponding ERETU would restore RFLAGS.TF = 1.
This combination causes a pending single-step trap upon completion of
ERETU. Therefore, another #DB is triggered before any user space
instruction is executed, which leads to an infinite loop in which the
SIGTRAP handler keeps being invoked on the same user space IP.

As ospi reset is consumed by both OMM and OSPI drivers, use the reset
acquire/release mechanism which ensure exclusive reset usage.
This avoid to call reset_control_get/put() in OMM driver each time
we need to reset OSPI children and guarantee the reset line stays
deasserted.
During resume, OMM driver takes temporarily control of reset.

Total: 13.2% on that simple loop.
But what the loop does is to multiply the boundary by 2 until it is
over the wanted border. This can be avoided by using fls() to get the
boundary value order and shift it by the appropriate number of bits at
once.
This change provides the following profile:

Currently hsmp_send_message() uses down_timeout() with a 100ms timeout
to take the semaphore. However __hsmp_send_message(), the content of the
critical section, has a sleep in it. On systems with significantly
delayed scheduling behaviour this may take over 100ms.
Convert this method to down_interruptible(). Leave the error handling
the same as the documentation currently is not specific about what error
is returned.
Previous behaviour: a caller who competes with another caller stuck in
the critical section due to scheduler delays would receive -ETIME.
New behaviour: a caller who competes with another caller stuck in the
critical section due to scheduler delays will complete successfully.

__hsmp_send_message sleeps between result read attempts and has a
timeout of 100ms. Under extreme load it's possible for these sleeps to
take a long time, exceeding the 100ms. In this case the current code
does not check the register and fails with ETIMEDOUT.
Refactor the loop to ensure there is at least one read of the register
after a sleep of any duration. This removes instances of ETIMEDOUT with
a single caller, even with a misbehaving scheduler. Tested on AMD
Bergamo machines.

The Sony DualSense wireless controller (PS5) features an internal mono
speaker, but it also provides a 3.5mm jack socket for headphone output
and headset microphone input.
Since this is a UAC1 device, it doesn't advertise any jack detection
capability. However, the controller is able to report HP & MIC insert
events via HID, i.e. through a dedicated input device managed by the
hid-playstation driver.
Add a quirk to create the jack controls for headphone and headset mic,
respectively, and setup an input handler for each of them in order to
intercept the related hotplug events.

The area of memory that contains the metrics table may contain garbage
when the cycle starts. This normally doesn't matter because the cycle
itself will populate it with valid data, however commit 9f5595d5f03fd
("platform/x86/amd: pmc: Require at least 2.5 seconds between HW sleep
cycles") started to use it during the check() phase. Depending upon
what garbage is in the table it's possible that the system will wait
2.5 seconds for even the first cycle, which will be visible to a user.
To prevent this from happening explicitly clear the table when logging
is started.

Address a Smatch static checker warning regarding an unchecked
dereference in the function call:
set_cdie_id(i, cluster_info, plat_info)
when plat_info is NULL.
Instead of addressing this one case, in general if plat_info is NULL
then it can cause other issues. For example in a two package system it
will give warning for duplicate sysfs entry as package ID will be always
zero for both packages when creating string for attribute group name.
plat_info is derived from TPMI ID TPMI_BUS_INFO, which is integral to
the core TPMI design. Therefore, it should not be NULL on a production
platform. Consequently, the module should fail to load if plat_info is
NULL.

It was reported that ideapad-laptop sometimes causes some recent (since
2024) Lenovo ThinkBook models shut down when:
- suspending/resuming
- closing/opening the lid
- (dis)connecting a charger
- reading/writing some sysfs properties, e.g., fan_mode, touchpad
- pressing down some Fn keys, e.g., Brightness Up/Down (Fn+F5/F6)
- (seldom) loading the kmod
The issue has existed since the launch day of such models, and there
have been some out-of-tree workarounds (see Link:) for the issue. One
disables some functionalities, while another one simply shortens
IDEAPAD_EC_TIMEOUT. The disabled functionalities have read_ec_data() in
their call chains, which calls schedule() between each poll.
It turns out that these models suffer from the indeterminacy of
schedule() because of their low tolerance for being polled too
frequently. Sometimes schedule() returns too soon due to the lack of
ready tasks, causing the margin between two polls to be too short.
In this case, the command is somehow aborted, and too many subsequent
polls (they poll for "nothing!") may eventually break the state machine
in the EC, resulting in a hard shutdown. This explains why shortening
IDEAPAD_EC_TIMEOUT works around the issue - it reduces the total number
of polls sent to the EC.
Even when it doesn't lead to a shutdown, frequent polls may also disturb
the ongoing operation and notably delay (+ 10-20ms) the availability of
EC response. This phenomenon is unlikely to be exclusive to the models
mentioned above, so dropping the schedule() manner should also slightly
improve the responsiveness of various models.
Fix these issues by migrating to usleep_range(150, 300). The interval is
chosen to add some margin to the minimal 50us and considering EC
responses are usually available after 150-2500us based on my test. It
should be enough to fix these issues on all models subject to the EC bug
without introducing latency on other models.
Tested on ThinkBook 14 G7+ ASP and solved both issues. No regression was
introduced in the test on a model without the EC bug (ThinkBook X IMH,
thanks Eric).

Driver unconditionally saves current state on first init in
dsi_pll_10nm_init(), but does not save the VCO rate, only some of the
divider registers. The state is then restored during probe/enable via
msm_dsi_phy_enable() -> msm_dsi_phy_pll_restore_state() ->
dsi_10nm_pll_restore_state().
Restoring calls dsi_pll_10nm_vco_set_rate() with
pll_10nm->vco_current_rate=0, which basically overwrites existing rate of
VCO and messes with clock hierarchy, by setting frequency to 0 to clock
tree. This makes anyway little sense - VCO rate was not saved, so
should not be restored.
If PLL was not configured configure it to minimum rate to avoid glitches
and configuring entire in clock hierarchy to 0 Hz.

When widebus was enabled for DisplayPort in commit c7c412202623
("drm/msm/dp: enable widebus on all relevant chipsets") it was clarified
that it is only supported on DPU 5.0.0 onwards which includes SC7180 on
DPU revision 6.2. However, this patch missed that the description
structure for SC7180 is also reused for SDM845 (because of identical
io_start address) which is only DPU 4.0.0, leading to a wrongly enbled
widebus feature and corruption on that platform.
Create a separate msm_dp_desc_sdm845 structure for this SoC compatible,
with the wide_bus_supported flag turned off.

When the last transfer of a SPI message has the cs_change flag, the CS is kept
asserted after the message.
The next message can't use multi-mode because the CS will be briefly deasserted
before the first transfer.

actually needs to be always checked.
