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

2026-02-26T23:01:16+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()

2026-01-15T13:55:32+00:00

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/pmf: Use devm_mutex_init() for mutex initialization

Replace mutex_init() with the devm_mutex_init(), to ensure proper mutex cleanup during probe failure and driver removal. Signed-off-by: Shyam Sundar S K Link: https://patch.msgid.link/20251119085813.546813-2-Shyam-sundar.S-k@amd.com Reviewed-by: Ilpo Järvinen Signed-off-by: Ilpo Järvinen

platform/x86/amd/pmf: Add BIOS_INPUTS_MAX macro to replace hardcoded array size

2025-11-27T11:58:27+00:00

Define a new macro BIOS_INPUTS_MAX, to represent the maximum number of BIOS input values. Replace hardcoded array sizes in relevant structures with this macro to improve readability and maintainability.

platform/x86/amd/pmf: Refactor repetitive BIOS output handling

2025-11-27T09:37:21+00:00

Replace repetitive switch-case statements for PMF_POLICY_BIOS_OUTPUT_* with a helper function and consolidated case handling. This reduces code duplication and improves maintainability. The 10 BIOS output policies (PMF_POLICY_BIOS_OUTPUT_1 through PMF_POLICY_BIOS_OUTPUT_10) previously each had individual case statements with identical logic. This patch introduces amd_pmf_get_bios_output_idx() to map policy values to array indices, consolidating the handling into a single case block with fallthrough. Also, add a new function amd_pmf_update_bios_output() to simplify the code handling. This approach handles non-sequential policy enum values gracefully and makes future additions easier to implement. No functional changes. Signed-off-by: Shyam Sundar S K Link: https://patch.msgid.link/20251127091038.2088387-1-Shyam-sundar.S-k@amd.com Reviewed-by: Ilpo Järvinen Signed-off-by: Ilpo Järvinen

platform/x86/amd/pmf: Replace magic table id with METRICS_TABLE_ID

2025-11-21T15:18:12+00:00

Add METRICS_TABLE_ID (7) and use it when requesting the metrics transfer table instead of the hard-coded literal. This clarifies the meaning of the argument to amd_pmf_send_cmd() and centralizes the table ID definition for easier maintenance.

Add SET_CMD and GET_CMD constants and replace boolean values passed as the get/set argument to amd_pmf_send_cmd() with the new explicit flags.
