2025-09-14platform/chrome: Centralize cros_ec_device allocationTzung-Bi Shih8-7/+22
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().

2025-09-11platform/x86/amd/pmf: Fix the custom bios input handling mechanismShyam Sundar S K2-19/+44
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.

2025-09-04platform/x86/intel-uncore-freq: Present unique domain ID per packageSrinivas Pandruvada1-1/+73
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.

2025-08-28platform/x86: asus-wmi: Fix racy registrationsTakashi Iwai1-1/+8
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.

2025-08-28platform/x86/intel-uncore-freq: Fix warning in partitioned systemSrinivas Pandruvada1-1/+1
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.

2025-08-25platform/x86: asus-wmi: Fix ROG button mapping, tablet mode on ASUS ROG Z13Antheas Kapenekakis2-5/+21
On commit 9286dfd5735b ("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.

Currently, the ignore_key_wlan quirk applies to keycodes 0x5D, 0x5E, and 0x5F. However, the relevant code for the Asus Zenbook Duo is only 0x5F. Since this code is emitted by other Asus devices, such as from the Z13 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.
