9188569860 platform/chrome: Centralize cros_ec_device allocation 
Introduce a helper function, cros_ec_device_alloc(), to centralize the
allocation of the struct cros_ec_device.  Convert all protocol device
drivers to use this new function.

This is a preparatory step for separating common initialization logic
out of device drivers' probe() and cros_ec_register().

a22bc86438 platform/x86:intel/pmc: Show substate requirement for S0ix blockers 
Add support to read and show S0ix blocker substate requirements.
Starting from Panther Lake, substate requirement data is provided
based on S0ix blockers instead of all low power mode requirements.
For platforms that support this new feature, add support to display
substate requirements based on S0ix blockers.

Change the "substate_requirements" attribute of Intel PMC Core
driver to show the substate requirements for each S0ix blocker
and the corresponding S0ix blocker value.

d82e3d2dd0 platform/x86/amd/pmf: Fix the custom bios input handling mechanism 
Originally, the 'amd_pmf_get_custom_bios_inputs()' function was written
under the assumption that the BIOS would only send a single pending
request for the driver to process. However, following OEM enablement, it
became clear that multiple pending requests for custom BIOS inputs might
be sent at the same time, a scenario that the current code logic does not
support when it comes to handling multiple custom BIOS inputs.

To address this, the code logic needs to be improved to not only manage
multiple simultaneous custom BIOS inputs but also to ensure it is scalable
for future additional inputs.

a191224186 platform/x86/intel-uncore-freq: Present unique domain ID per package 
In partitioned systems, the domain ID is unique in the partition and a
package can have multiple partitions.

Some user-space tools, such as turbostat, assume the domain ID is unique
per package. These tools map CPU power domains, which are unique to a
package. However, this approach does not work in partitioned systems.

There is no architectural definition of "partition" to present to user
space.

To support these tools, set the domain_id to be unique per package. For
compute die IDs, uniqueness can be achieved using the platform info
cdie_mask, mirroring the behavior observed in non-partitioned systems.

For IO dies, which lack a direct CPU relationship, any unique logical
ID can be assigned. Here domain IDs for IO dies are configured after all
compute domain IDs. During the probe, keep the index of the next IO
domain ID after the last IO domain ID of the current partition. Since
CPU packages are symmetric, partition information is same for all
packages.

The Intel Speed Select driver has already implemented a similar change
to make the domain ID unique, with compute dies listed first, followed
by I/O dies.

aa28991fd5 platform/x86/intel: power-domains: Use topology_logical_package_id() for package ID 
Currently, tpmi_get_logical_id() calls topology_physical_package_id()
to set the pkg_id of the info structure. Since some VM hosts assign non
contiguous package IDs, topology_physical_package_id() can return a
larger value than topology_max_packages(). This will result in an
invalid reference into tpmi_power_domain_mask[] as that is allocatead
based on topology_max_packages() as the maximum package ID.

b0908e03fd platform/x86: acer-wmi: Stop using ACPI bitmap for platform profile choices 
It turns out that the platform firmware on some models does not return
valid data when reading the bitmap of supported platform profiles.
This prevents the driver from loading on said models, even when the
platform profile interface itself works.

Fix this by stop using said bitmap until we have figured out how
the OEM software itself detects available platform profiles.

23408874e9 platform/x86: hp-wmi: Add support for Fn+P hotkey 
Add support for the Fn+P hotkey found on newer HP Victus (and probably
newer Omen) laptops. This hotkey is intended for use with Omen Gaming Hub
to change the performance profile (see [1]).

Pressing Fn+P under linux produced the following warning in dmesg:

> hp_wmi: Unknown event_id - 27 - 0x7

Implemented a handling for this event so that the hotkey cycles between the
platform profiles when triggered.

Tested on Victus 16-s1011nt (9Z791EA, MB 8C9C).

Changes in v2:
- Make the key just switches between platform profiles instead of
  assigning a key event code.
- v1: https://lore.kernel.org/all/20250802213541.18791-2-edip@medip.dev/

asus_wmi_register_driver() may be called from multiple drivers
concurrently, which can lead to the racy list operations, eventually
corrupting the memory and hitting Oops on some ASUS machines.
Also, the error handling is missing, and it forgot to unregister ACPI
lps0 dev ops in the error case.

This patch covers those issues by introducing a simple mutex at
acpi_wmi_register_driver() & *_unregister_driver, and adding the
proper call of asus_s2idle_check_unregister() in the error path.

6d47b4f084 platform/x86/intel-uncore-freq: Fix warning in partitioned system 
A partitioned system configured with only one package and one compute
die, warning will be generated for duplicate sysfs entry. This typically
occurs during the platform bring-up phase.

Partitioned systems expose dies, equivalent to TPMI compute domains,
through the CPUID. Each partitioned system must contains at least one
compute die per partition, resulting in a minimum of two dies per
package. Hence the function topology_max_dies_per_package() returns at
least two, and the condition "topology_max_dies_per_package() > 1"
prevents the creation of a root domain.

In this case topology_max_dies_per_package() will return 1 and root
domain will be created for partition 0 and a duplicate sysfs warning
for partition 1 as both partitions have same package ID.

To address this also check for non zero partition in addition to
topology_max_dies_per_package() > 1.

132bfcd249 platform/x86: asus-wmi: Fix ROG button mapping, tablet mode on ASUS ROG Z13 
On commit 9286dfd573 ("platform/x86: asus-wmi: Fix spurious rfkill on
UX8406MA"), Mathieu adds a quirk for the Zenbook Duo to ignore the code
0x5f (WLAN button disable). On that laptop, this code is triggered when
the device keyboard is attached.

On the ASUS ROG Z13 2025, this code is triggered when pressing the side
button of the device, which is used to open Armoury Crate in Windows.

As this is becoming a pattern, where newer Asus laptops use this keycode
for emitting events, let's convert the wlan ignore quirk to instead
allow emitting codes, so that userspace programs can listen to it and
so that it does not interfere with the rfkill state.

With this patch, the Z13 wil emit KEY_PROG3 and the Duo will remain
unchanged and emit no event. While at it, add a quirk for the Z13 to
switch into tablet mode when removing the keyboard.

for its ROG button, remove the extra codes before expanding the quirk.

For the Duo devices, which are the only ones that use this quirk, there
should be no effect.
