platform/x86/amd/pmc: Add PCSpecialist Lafite Pro V 14M to 8042 quirks list
Every other s2idle cycle fails to reach hardware sleep when keyboard wakeup is enabled. This appears to be an EC bug, but the vendor refuses to fix it. It was confirmed that turning off i8042 wakeup avoids ths issue (albeit keyboard wakeup is disabled). Take the lesser of two evils and add it to the i8042 quirk list.

platform/x86/intel-uncore-freq: avoid non-literal format string
Using a string variable in place of a format string causes a W=1 build warning:
drivers/platform/x86/intel/uncore-frequency/uncore-frequency-common.c:61:40: error: format string is not a string literal (potentially insecure) [-Werror,-Wformat-security]
61 | length += sysfs_emit_at(buf, length, agent_name[agent]);

Use the safer "%s" format string to print it instead.

platform/x86: dell_rbu: Stop overwriting data buffer
The dell_rbu driver will use memset() to clear the data held by each
packet when it is no longer needed (when the driver is unloaded, the
packet size is changed, etc).
The amount of memory that is cleared (before this patch) is the normal
packet size. However, the last packet in the list may be smaller.
Fix this to only clear the memory actually used by each packet, to prevent
it from writing past the end of data buffer.
Because the packet data buffers are allocated with __get_free_pages() (in
page-sized increments), this bug could only result in a buffer being
overwritten when a packet size larger than one page is used. The only user
of the dell_rbu module should be the Dell BIOS update program, which uses
a packet size of 4096, so no issues should be seen without the patch, it
just blocks the possiblity.

platform/x86: dell_rbu: Fix list usage
Pass the correct list head to list_for_each_entry*() when looping through
the packet list.
Without this patch, reading the packet data via sysfs will show the data
incorrectly (because it starts at the wrong packet), and clearing the
packet list will result in a NULL pointer dereference.

platform/x86/amd: pmf: Use device managed allocations
If setting up smart PC fails for any reason then this can lead to
a double free when unloading amd-pmf. This is because dev->buf was
freed but never set to NULL and is again freed in amd_pmf_remove().
To avoid subtle allocation bugs in failures leading to a double free
change all allocations into device managed allocations.

x86/platform/amd: replace down_timeout() with down_interruptible()
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.

x86/platform/amd: move final timeout check to after final sleep
__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.

platform/x86/intel-uncore-freq: Fail module load when plat_info is NULL
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.

platform/x86: ideapad-laptop: use usleep_range() for EC polling
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). Link: |

platform/loongarch: laptop: Get brightness setting from EC on probe
Previously during driver probe, 1 is unconditionally taken as current
brightness value and set to props.brightness, which will be considered
as the brightness before suspend and restored to EC on resume. Since a
brightness value of 1 almost never matches EC's state on coldboot (my
laptop's EC defaults to 80), this causes surprising changes of screen
brightness on the first time of resume after coldboot.
Let's get brightness from EC and take it as the current brightness on
probe of the laptop driver to avoid the surprising behavior. Tested on
TongFang L860-T2 Loongson-3A5000 laptop.

gpio updates for v6.16-rc1
GPIO core:
- use more lock guards where applicable
- refactor GPIO ACPI code and shrink it in the process by 8%
- move GPIO ACPI quirks into a separate file
- remove unneeded #ifdef
- convert GPIO devres helpers to using devm_add_action() where applicable
which shrinks and simplifies the code
- refactor GPIO descriptor validation in GPIO consumer interfaces
- don't allow setting values on input lines in the GPIO core which will
take off the burden from GPIO drivers of checking this down the line
- provide gpiod_is_equal() as a way of safely comparing two GPIO
descriptors (the only current user is in regulator core)
New drivers:
- add the GPIO module for the max77759 multifunction device
- add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
- add the GPIO driver for the Spacemit K1 SoC
Driver improvements:
- convert more drivers to using the new GPIO line value setter callbacks
- convert more drivers to making the irq_chip immutable as is recommended
by the interrupt subsystem
- extend build testing coverage by enabling more modules to be built with
COMPILE_TEST=y
- extend the gpio-aggregator module with a configfs interface that makes
the setup easier for user-space than the existing driver-level sysfs
attributes and also adds more advanced configuration features (such as
referring to aggregated lines by their original names or modifying
their names as exposed by the aggregated chip)
- add a missing mutex_destroy() in gpio-imx-scu
- add an OF polarity quirk for s5m8767
- allow building gpio-vf610 as a loadable module
- make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS
interface disabled (another small step towards getting rid of the global
GPIO numberspace)
- add support for level-triggered interrupts to gpio-pca953x
- don't double-check the ngpios property in gpio-ds4520 as GPIO core
already does it
- don't double-check the number of GPIOs in gpio-imx-scu as GPIO core
already does it
- remove unused callbacks from gpio-max3191x
DT bindings:
- add device-tree bindings for max77759, spacemit,k1 and blzp1600 (new
drivers added this cycle)
- document more properties for gpio-vf610 and gpio-tegra186
- document a new pca95xx variant
- fix style of examples in several GPIO DT-binding documents
Misc:
- TODO list updates

Pull gpio updates from Bartosz Golaszewski:
"We have three new drivers, some refactoring in the GPIO core, lots of
various changes across many drivers, new configfs interface for the
virtual gpio-aggregator module and DT-bindings updates.
The treewide conversion of GPIO drivers to using the new value setter
callbacks is ongoing with another round of GPIO drivers updated. You
will also see these commits coming in from other subsystems as with
the relevant changes merged into mainline last cycle, I've started
converting GPIO providers located elsewhere than drivers/gpio/.

- add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
- add the GPIO driver for the Spacemit K1 SoC
Driver improvements:
- convert more drivers to using the new GPIO line value setter
callbacks
- convert more drivers to making the irq_chip immutable as is
recommended by the interrupt subsystem
- extend build testing coverage by enabling more modules to be built
with COMPILE_TEST=y
- extend the gpio-aggregator module with a configfs interface that
makes the setup easier for user-space than the existing
driver-level sysfs attributes and also adds more advanced
configuration features (such as referring to aggregated lines by
their original names or modifying their names as exposed by the
aggregated chip)
- add a missing mutex_destroy() in gpio-imx-scu
- add an OF polarity quirk for s5m8767
- allow building gpio-vf610 as a loadable module
- make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS
interface disabled (another small step towards getting rid of the
global GPIO numberspace)
- add support for level-triggered interrupts to gpio-pca953x
- don't double-check the ngpios property in gpio-ds4520 as GPIO core
already does it
- don't double-check the number of GPIOs in gpio-imx-scu as GPIO core
already does it
- remove unused callbacks from gpio-max3191x
DT bindings:
- add device-tree bindings for max77759, spacemit,k1 and blzp1600
(new drivers added this cycle)
- document more properties for gpio-vf610 and gpio-tegra186
- document a new pca95xx variant
- fix style of examples in several GPIO DT-binding documents

thermal/drivers/acerhdf: Constify struct thermal_zone_device_ops
'struct thermal_zone_device_ops' could be left unmodified in this driver. Constifying this structure moves some data to a read-only section, so increases overall security, especially when the structure holds some function pointers.

platform/x86/intel/pmc: Fix Arrow Lake U/H NPU PCI ID
The ARL requires that the GMA and NPU devices both be in D3Hot in order
for PC10 and S0iX to be achieved in S2idle. The original ARL-H/U addition
to the intel_pmc_core driver attempted to do this by switching them to D3
in the init and resume calls of the intel_pmc_core driver.
The problem is the ARL-H/U have a different NPU device and thus are not
being properly set and thus S0iX does not work properly in ARL-H/U. This
patch creates a new ARL-H specific device id that is correct and also
adds the D3 fixup to the suspend callback. This way if the PCI devies
drop from D3 to D0 after resume they can be corrected for the next
suspend. Thus there is no dropout in S0iX.

platform/x86: think-lmi: Fix attribute name usage for non-compliant items
A few, quite rare, WMI attributes have names that are not compatible with
filenames, e.g. "Intel VT for Directed I/O (VT-d)".
For these cases the '/' gets replaced with '\' for display, but doesn't
get switched again when doing the WMI access.
Fix this by keeping the original attribute name and using that for sending
commands to the BIOS

x86/cpuid: Set <asm/cpuid/api.h> as the main CPUID header
The main CPUID header <asm/cpuid.h> was originally a storefront for the
headers:
<asm/cpuid/api.h>
<asm/cpuid/leaf_0x2_api.h>
Now that the latter CPUID(0x2) header has been merged into the former,
there is no practical difference between <asm/cpuid.h> and
<asm/cpuid/api.h>.
Migrate all users to the <asm/cpuid/api.h> header, in preparation of
the removal of <asm/cpuid.h>.
Don't remove <asm/cpuid.h> just yet, in case some new code in -next
started using it.

platform/x86/intel-uncore-freq: Add attributes to show die_id
For domains with agents to control cores (compute dies) show matching Linux CPU die ID. Linux CPU ID is a logical die ID, so this may not match physical die ID or domain_id. So, a mapping is required to get Linux CPU die ID. This attribute is only presented when CPUID enumerates die ids.

platform/x86/intel-uncore-freq: Add attributes to show agent types
Currently, users need detailed hardware information to understand the scope of controls within each uncore domain. Uncore frequency controls manage subsystems such as core, cache, memory, and I/O. The UFS TPMI provides this information, which can be used to present the scope more clearly. Each uncore domain consists of one or more agent types, with each agent type controlling one or more uncore hardware subsystems. For example, a single agent might control both the core and cache. Introduce a new attribute called "agent_types." This attribute displays a list of agents, separated by space character. The string representations for agent types are as follows: For core agent: core For cache agent: cache For memory agent: memory For I/O agent: io These agent types are read during probe time for each cluster and stored as part of the struct uncore_data.
