platform/x86/amd/pmf: Prevent TEE errors after hibernate

2026-02-26T22:59:25+00:00

[ Upstream commit 48d229c7047128dd52eaf863881bb3e62b5896e5 ] After resuming from hibernate, TEE commands can time out and cause PSP disables. Fix this by reinitializing the Trusted Application (TA) and cancelling the pb workqueue in the hibernate callbacks to avoid these errors. ccp 0000:c4:00.2: tee: command 0x5 timed out, disabling PSP amd-pmf AMDI0107:00: TEE enact cmd failed. err: ffff000e, ret:0 amd-pmf AMDI0107:00: TEE enact cmd failed. err: ffff000e, ret:0 amd-pmf AMDI0107:00: TEE enact cmd failed. err: ffff000e, ret:0 Fixes: ae82cef7d9c5 ("platform/x86/amd/pmf: Add support for PMF-TA interaction") Reported-by: Lars Francke Closes: https://lore.kernel.org/platform-driver-x86/CAD-Ua_gfJnQSo8ucS_7ZwzuhoBRJ14zXP7s8b-zX3ZcxcyWePw@mail.gmail.com/ Tested-by: Yijun Shen Co-developed-by: Patil Rajesh Reddy Signed-off-by: Patil Rajesh Reddy Signed-off-by: Shyam Sundar S K [ML: Add more tags] Signed-off-by: Mario Limonciello (AMD) Link: https://patch.msgid.link/20260116041132.153674-2-superm1@kernel.org Signed-off-by: Ilpo Järvinen Signed-off-by: Sasha Levin

platform/x86/amd: Fix memory leak in wbrf_record()

2026-01-30T09:32:16+00:00

[ Upstream commit 2bf1877b7094c684e1d652cac6912cfbc507ad3e ] The tmp buffer is allocated using kcalloc() but is not freed if acpi_evaluate_dsm() fails. This causes a memory leak in the error path. Fix this by explicitly freeing the tmp buffer in the error handling path of acpi_evaluate_dsm().

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

2025-11-06T12:19:32+00:00

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

2025-11-06T12:19:31+00:00

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

2025-11-06T12:19:29+00:00

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.
