2025-09-04platform/x86/intel-uncore-freq: Present unique domain ID per packageSrinivas Pandruvada
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.

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.

2025-08-28platform/x86/intel-uncore-freq: Fix warning in partitioned systemSrinivas Pandruvada
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 Kapenekakis
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.

Instead of hardcoding the regulator enable-time for INT3472_GPIO_TYPE- POWER_ENABLE and -HANDSHAKE, make int3472_get_con_id_and_polarity() set the enable-time. This will allow overriding the enable time through quirks in the int3472_gpio_map[].

2025-08-12platform/x86/amd: pmc: Drop SMU F/W match for CezanneMario Limonciello
Chris reported that even on a BIOS that has a new enough SMU F/W version there is still a spurious IRQ1. Although the solution was added to SMU F/W 64.66.0 it turns out there needs to be a matching SBIOS change to activate it. Thus Linux shouldn't be avoiding the IRQ1 workaround on newer SMU F/W because there is no indication the BIOS change is in place. Drop the match for 64.66.0+ and instead match all RN/CZN/BRC (they all share same SMU F/W). Adjust the quirk infrastructure to allow quirking the workaround on or off and also adjust existing quirks to match properly. Unfortunately this may cause some systems that did have the SBIOS change in place to regress in keyboard wakeup but we don't have a way to know. If a user reports a keyboard wakeup regression they can run with amd_pmc.disable_workarounds=1 to deactivate the workaround and share DMI data so that their system can be quirked not to use the workaround in the upstream kernel.

2025-08-12platform/x86: dell-smbios-wmi: Stop touching WMI device IDArmin Wolf
The Dell SMBIOS driver uses the "id" field inside struct device for prioritizing the WMI backend over the SMM backend. Because of this the WMI backend modifies the "id" field of the underlying WMI device. However the WMI core itself uses wdev->dev.id internally to track device IDs, so modifying this value will result in a resource leak. Fix this by not using the "id" field inside struct device for SMBIOS prioritization. Instead extend struct smbios_device with a separate "priority" field. Tested on a Dell Inspiron 3505.
