drm/amdgpu: prevent NULL pointer dereference if ATIF is not supported

2024-11-14T12:21:07+00:00

commit a6dd15981c03f2cdc9a351a278f09b5479d53d2e upstream. acpi_evaluate_object() may return AE_NOT_FOUND (failure), which would result in dereferencing buffer.pointer (obj) while being NULL. Although this case may be unrealistic for the current code, it is still better to protect against possible bugs. Bail out also when status is AE_NOT_FOUND.

drm/amd/display: parse umc_info or vram_info based on ASIC

2024-11-14T12:21:06+00:00

commit 694c79769cb384bca8b1ec1d1e84156e726bd106 upstream. An upstream bug report suggests that there are production dGPUs that are older than DCN401 but still have a umc_info in VBIOS tables with the same version as expected for a DCN401 product. Hence, reading this tables should be guarded with a version check.

drm/amd/pm: correct the workload setting

commit 74e1006430a5377228e49310f6d915628609929e upstream. Correct the workload setting in order not to mix the setting with the end user. Update the workload mask accordingly. v2: changes as below: 1. the end user can not erase the workload from driver except default workload. 2. always shows the real highest priority workoad to the end user. 3. the real workload mask is combined with driver workload mask and end user workload mask. v3: apply this to the other ASICs as well. v4: simplify the code v5: refine the code based on the review comments.
