chrome platform changes for 6.5
* Improvements
- Support Pin Assignment D in getting mux state.
- Emit an uevent when EC panics so that userland programs get chance
to capture EC coredumps (LPC interface only).
- Send EC_CMD_HOST_SLEEP_EVENT to EC at the very beginning/end of
system suspend/resume so that EC can watch the duration more
accurately (LPC interface only).
* Misc
- Switch back from I2C .probe_new() to .probe().
- Use %*ph for printing hexdump of small buffers.

Power management updates for 6.5-rc1
- Introduce power capping core support for Intel TPMI (Topology Aware
Register and PM Capsule Interface) and a TPMI interface driver for
Intel RAPL (Zhang Rui, Dan Carpenter).
- Fix CONFIG_IOSF_MBI dependency in the Intel RAPL power capping
driver (Zhang Rui).
- Fix invalid initialization for pl4_supported field in the Intel RAPL
power capping driver (Sumeet Pawnikar).
- Clean up the intel_idle driver, make it work with VM guests that
cannot use the MWAIT instruction and address the case in which the
host may enter a deep idle state when the guest is idle (Arjan van
de Ven).
- Prevent cpufreq drivers that provide the ->adjust_perf() callback
without a ->fast_switch() one which is used as a fallback from the
former in some cases (Wyes Karny).
- Fix some issues related to the AMD P-state cpufreq driver (Mario
Limonciello, Wyes Karny).
- Fix the energy_performance_preference attribute handling in the
intel_pstate driver in passive mode (Tero Kristo).
- Fix the handling of pm_suspend_target_state when CONFIG_PM is unset
(Kai-Heng Feng).
- Correct spelling mistake in a comment in the hibernation code (Wang
Honghui).
- Add arch_resume_nosmt() prototype to avoid a "missing prototypes"
build warning (Arnd Bergmann).
- Restrict pm_pr_dbg() to system-wide power transitions and use it in
a few additional places (Mario Limonciello).
- Drop verification of in-params from genpd_add_device() and ensure
that all of its callers will do it (Ulf Hansson).
- Prevent possible integer overflows from occurring in
genpd_parse_state() (Nikita Zhandarovich).
- Reorder fieldls in 'struct devfreq_dev_status' to reduce its size
somewhat (Christophe JAILLET).
- Ensure that the Exynos PPMU driver is already loaded before the
Exynos Bus driver starts probing so as to avoid a possible freeze
loading of the kernel modules (Marek Szyprowski).
- Fix variable deferencing before NULL check in the mtk-cci devfreq
driver (Sukrut Bellary).

platform/surface: aggregator: Allow completion work-items to be executed in parallel
Currently, event completion work-items are restricted to be run strictly
in non-parallel fashion by the respective workqueue. However, this has
lead to some problems:
In some instances, the event notifier function called inside this
completion workqueue takes a non-negligible amount of time to execute.
One such example is the battery event handling code (surface_battery.c),
which can result in a full battery information refresh, involving
further synchronous communication with the EC inside the event handler.
This is made worse if the communication fails spuriously, generally
incurring a multi-second timeout.
Since the event completions are run strictly non-parallel, this blocks
other events from being propagated to the respective subsystems. This
becomes especially noticeable for keyboard and touchpad input, which
also funnel their events through this system. Here, users have reported
occasional multi-second "freezes".
Note, however, that the event handling system was never intended to run
purely sequentially. Instead, we have one work struct per EC/SAM
subsystem, processing the event queue for that subsystem. These work
structs were intended to run in parallel, allowing sequential processing
of work items for each subsystem but parallel processing of work items
across subsystems.
The only restriction to this is the way the workqueue is created.
Therefore, replace create_workqueue() with alloc_workqueue() and do not
restrict the maximum number of parallel work items to be executed on
that queue, resolving any cross-subsystem blockage.

platform/x86: thinkpad_acpi: Add profile force ability
There has been a lot of confusion around which platform profiles are supported on various platforms and it would be useful to have a debug method to be able to override the profile mode that is selected. I don't expect this to be used in anything other than debugging in conjunction with Lenovo engineers - but it does give a way to get a system working whilst we wait for either FW fixes, or a driver fix to land upstream, if something is wonky in the mode detection logic Signed-off-by: Mark Pearson <mpearson-lenovo@squebb.ca> Link: https://lore.kernel.org/r/20230505132523.214338-2-mpearson-lenovo@squebb.ca Cc: stable@vger.kernel.org Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> |

platform/x86: thinkpad_acpi: Fix platform profiles on T490
I had incorrectly thought that PSC profiles were not usable on Intel
platforms so had blocked them in the driver initialistion. This broke
platform profiles on the T490.
After discussion with the FW team PSC does work on Intel platforms and
should be allowed.
Note - it's possible this may impact other platforms where it is advertised
but special driver support that only Windows has is needed. But if it does
then they will need fixing via quirks. Please report any issues to me so I
can get them addressed - but I haven't found any problems in testing...yet

modules-6.4-rc1
The summary of the changes for this pull requests is:
* Song Liu's new struct module_memory replacement
* Nick Alcock's MODULE_LICENSE() removal for non-modules
* My cleanups and enhancements to reduce the areas where we vmalloc
module memory for duplicates, and the respective debug code which
proves the remaining vmalloc pressure comes from userspace.
Most of the changes have been in linux-next for quite some time except
the minor fixes I made to check if a module was already loaded
prior to allocating the final module memory with vmalloc and the
respective debug code it introduces to help clarify the issue. Although
the functional change is small it is rather safe as it can only *help*
reduce vmalloc space for duplicates and is confirmed to fix a bootup
issue with over 400 CPUs with KASAN enabled. I don't expect stable
kernels to pick up that fix as the cleanups would have also had to have
been picked up. Folks on larger CPU systems with modules will want to
just upgrade if vmalloc space has been an issue on bootup.
Given the size of this request, here's some more elaborate details
on this pull request.
The functional change change in this pull request is the very first
patch from Song Liu which replaces the struct module_layout with a new
struct module memory. The old data structure tried to put together all
types of supported module memory types in one data structure, the new
one abstracts the differences in memory types in a module to allow each
one to provide their own set of details. This paves the way in the
future so we can deal with them in a cleaner way. If you look at changes
they also provide a nice cleanup of how we handle these different memory
areas in a module. This change has been in linux-next since before the
merge window opened for v6.3 so to provide more than a full kernel cycle
of testing. It's a good thing as quite a bit of fixes have been found
for it.
Jason Baron then made dynamic debug a first class citizen module user by
using module notifier callbacks to allocate / remove module specific
dynamic debug information.
Nick Alcock has done quite a bit of work cross-tree to remove module
license tags from things which cannot possibly be module at my request
so to:
a) help him with his longer term tooling goals which require a
deterministic evaluation if a piece a symbol code could ever be
part of a module or not. But quite recently it is has been made
clear that tooling is not the only one that would benefit.
Disambiguating symbols also helps efforts such as live patching,
kprobes and BPF, but for other reasons and R&D on this area
is active with no clear solution in sight.
b) help us inch closer to the now generally accepted long term goal
of automating all the MODULE_LICENSE() tags from SPDX license tags
In so far as a) is concerned, although module license tags are a no-op
for non-modules, tools which would want create a mapping of possible
modules can only rely on the module license tag after the commit

Driver core changes for 6.4-rc1
Here is the large set of driver core changes for 6.4-rc1. Once again, a busy development cycle, with lots of changes happening in the driver core in the quest to be able to move "struct bus" and "struct class" into read-only memory, a task now complete with these changes. This will make the future rust interactions with the driver core more "provably correct" as well as providing more obvious lifetime rules for all busses and classes in the kernel. The changes required for this did touch many individual classes and busses as many callbacks were changed to take const * parameters instead. All of these changes have been submitted to the various subsystem maintainers, giving them plenty of time to review, and most of them actually did so. Other than those changes, included in here are a small set of other things: - kobject logging improvements - cacheinfo improvements and updates - obligatory fw_devlink updates and fixes - documentation updates - device property cleanups and const * changes - firwmare loader dependency fixes.

spi: Updates for v6.4
A fairly standard release for SPI with the exception of a change to the
API for specifying chip selects done in preparation for supporting
devices with more than one chip select, this required some mechanical
changes throughout the tree which have been cooking in -next happily for
a while. There's also a new API to allow us to TPM chips on half duplex
controllers.
There's three commits in here that were mangled by a bad interaction
between the alsa-devel mailing list software and b4, I didn't notice
until there were merges on top with it being SPI not ALSA. It seemed
clear enough to not be worth going back and fixing.
- Refactoring in preparation for supporting multiple chip selects for a
single device, needed by some flash devices, which required a change
in the SPI device API visible throughout the tree.
- Support for hardware assisted interaction with SPI TPMs on half
duplex controllers, implemented on nVidia Tedra210 QuadSPI.
- Optimisation for large transfers on fsl-cpm devices.
- Cleanups around device property use which fix some sisues with
fwnode.
- Use of both void remove() and devm_platform_.*ioremap_resource().
- Support for AMD Pensando Elba, Amlogic A1, Cadence device mode,
Intel MetorLake-S and StarFive J7110 QuadSPI.
The final commit converting to DEV_PM_OPS() was applied late to fix a
warning that was introduced by some of the earlier work.

Pull thermal control updates from Rafael Wysocki:
"These mostly continue to prepare the thermal control subsystem for
using unified representation of trip points, which includes cleanups,
code refactoring and similar and update several drivers (for other
reasons), which includes new hardware support.
Specifics:
- Add a thermal zone 'devdata' accessor and modify several drivers to
use it (Daniel Lezcano)

structure field directly, access the sensor device instead the
thermal zone's device for trace, relocate the traces in
drivers/thermal (Daniel Lezcano)
- Use the generic trip point for the i.MX and remove the
get_trip_temp ops (Daniel Lezcano)
- Use the devm_platform_ioremap_resource() in the Hisilicon driver
(Yang Li)
- Remove R-Car H3 ES1.* handling as public has only access to the ES2
version and the upstream support for the ES1 has been shutdown
(Wolfram Sang)
- Add a delay after initializing the bank in order to let the time to
the hardware to initialze itself before reading the temperature
(Amjad Ouled-Ameur)

- Preparational cleanup and DT bindings for RK3588 support (Sebastian
Reichel)
- Add driver support for RK3588 (Finley Xiao)
- Use devm_reset_control_array_get_exclusive() for the Rockchip
driver (Ye Xingchen)
- Detect power gated thermal zones and return -EAGAIN when reading
the temperature (Mikko Perttunen)
- Remove thermal_bind_params structure as it is unused (Zhang Rui)
- Drop unneeded quotes in DT bindings allowing to run yamllint (Rob
Herring)
- Update the power allocator documentation according to the thermal
trace relocation (Lukas Bulwahn)
- Fix sensor 1 interrupt status bitmask for the Mediatek LVTS sensor
(Chen-Yu Tsai)
- Use the dev_err_probe() helper in the Amlogic driver (Ye Xingchen)
- Add AP domain support to LVTS thermal controllers for mt8195
(Balsam CHIHI)
- Remove buggy call to thermal_of_zone_unregister() (Daniel Lezcano)
- Make thermal_of_zone_[un]register() private to the thermal OF code
(Daniel Lezcano)
- Create a private copy of the thermal zone device parameters
structure when registering a thermal zone (Daniel Lezcano)
- Fix a kernel NULL pointer dereference in thermal_hwmon (Zhang Rui)
- Revert recent message adjustment in thermal_hwmon (Rafael Wysocki)
- Use of_property_present() for testing DT property presence in
thermal control code (Rob Herring)

Change DEFINE_SEMAPHORE() to take a number argument
Fundamentally semaphores are a counted primitive, but DEFINE_SEMAPHORE() does not expose this and explicitly creates a binary semaphore. Change DEFINE_SEMAPHORE() to take a number argument and use that in the few places that open-coded it using __SEMAPHORE_INITIALIZER().

platform/x86: thinkpad_acpi: Fix Embedded Controller access on X380 Yoga
On the X380 Yoga, the `ECRD` and `ECWR` ACPI objects cannot be used for accessing the Embedded Controller: instead of a method that reads from the EC's memory, `ECRD` is the name of a location in high memory. This meant that trying to call them would fail with the following message: ACPI: \_SB.PCI0.LPCB.EC.ECRD: 1 arguments were passed to a non-method ACPI object (RegionField) With this commit, it is now possible to access the EC and read temperature and fan speed information. Note that while writes to the HFSP register do go through (as indicated by subsequent reads showing the new value), the fan does not actually change its speed.
