2026-01-26T14:43:51Z

The MECHREVO Wujie 15X Pro suffers from spurious IRQ issues related to the AMD PMC. Add it to the quirk list to use the spurious_8042 fix. Signed-off-by: gongqi <550230171hxy@gmail.com> Link: https://patch.msgid.link/20260122155501.376199-4-550230171hxy@gmail.com Signed-off-by: Ilpo Järvinen

platform/x86/amd: pmc: Add Lenovo Legion Go 2 to pmc quirk list

2025-11-06T12:19:32Z

The Lenovo Legion Go 2 takes a long time to resume from suspend. This is due to it having an nvme resume handler that interferes with IOMMU mappings. It is a common issue with older Lenovo laptops. Adding it to that quirk list fixes this issue.

platform/x86/amd/pmc: Add spurious_8042 to Xbox Ally

2025-11-06T12:19:31Z

The Xbox Ally features a Van Gogh SoC that has spurious interrupts during resume. We get the following logs: atkbd_receive_byte: 20 callbacks suppressed atkbd serio0: Spurious ACK on isa0060/serio0. Some program might be trying to access hardware directly. So, add the spurious_8042 quirk for it. It does not have a keyboard, so this does not result in any functional loss.

platform/x86/amd/pmc: Add support for Van Gogh SoC

2025-11-06T12:19:29Z

The ROG Xbox Ally (non-X) SoC features a similar architecture to the Steam Deck. While the Steam Deck supports S3 (s2idle causes a crash), this support was dropped by the Xbox Ally which only S0ix suspend. Since the handler is missing here, this causes the device to not suspend and the AMD GPU driver to crash while trying to resume afterwards due to a power hang.

platform/x86/amd/pmc: Add MECHREVO Yilong15Pro to spurious_8042 list

2025-09-10T11:17:56Z

The firmware of Mechrevo Yilong15Pro emits a spurious keyboard interrupt on events including closing the lid. When a user closes the lid on an already suspended system this causes the system to wake up. Add Mechrevo Yilong15Pro Series (GM5HG7A) to the list of quirk spurious_8042 to work around this issue.

Prevents instant wakeup ~1s after suspend. It seems to be kernel/system dependent if the IRQ actually manages to wake the system every time or if it gets ignored (and everything works as expected).

platform/x86/amd: pmc: Drop SMU F/W match for Cezanne

2025-08-12T12:02:31Z

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.

Move FCH header to a location accessible by all archs

2025-06-30T10:42:11Z

A new header fch.h was created to store registers used by different AMD drivers. This header was included by i2c-piix4 in commit 624b0d5696a8 ("i2c: piix4, x86/platform: Move the SB800 PIIX4 FCH definitions to "). To prevent compile failures on non-x86 archs i2c-piix4 was set to only compile on x86 by commit 7e173eb82ae9717 ("i2c: piix4: Make CONFIG_I2C_PIIX4 dependent on CONFIG_X86"). This was not a good decision because loongarch and mips both actually support i2c-piix4 and set it enabled in the defconfig. Move the header to a location accessible by all architectures.
