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

2026-03-25T10:06:01+00:00

[ Upstream commit db4a3f0fbedb0398f77b9047e8b8bb2b49f355bb ] 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 spurious_8042 to Xbox Ally

2026-01-11T14:21:10+00:00

[ Upstream commit c0ddc54016636dd8dedfaf1a3b482a95058e1db2 ] 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 Lenovo Legion Go 2 to pmc quirk list

[ Upstream commit f945afe01c6768dcfed7868c671a26e1164c2284 ] 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 MECHREVO Yilong15Pro to spurious_8042 list

[ Upstream commit 8822e8be86d40410ddd2ac8ff44f3050c9ecf9c6 ] 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.

commit c96f86217bb28e019403bb8f59eacd8ad5a7ad1a upstream. 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).

[ Upstream commit 9ba75ccad85708c5a484637dccc1fc59295b0a83 ] Every other s2idle cycle fails to reach hardware sleep when keyboard wakeup is enabled. This appears to be an EC bug, but the vendor refuses to fix it. It was confirmed that turning off i8042 wakeup avoids ths issue (albeit keyboard wakeup is disabled). Take the lesser of two evils and add it to the i8042 quirk list.

platform/x86/amd: pmc: Clear metrics table at start of cycle

2025-06-27T10:08:57+00:00

[ Upstream commit 4dbd11796f3a8eb95647507befc41995458a4023 ] The area of memory that contains the metrics table may contain garbage when the cycle starts. This normally doesn't matter because the cycle itself will populate it with valid data, however commit 9f5595d5f03fd ("platform/x86/amd: pmc: Require at least 2.5 seconds between HW sleep cycles") started to use it during the check() phase. Depending upon what garbage is in the table it's possible that the system will wait 2.5 seconds for even the first cycle, which will be visible to a user. To prevent this from happening explicitly clear the table when logging is started.
