drm/amdgpu: Drop PMFW RLC notifier from amdgpu_device_suspend()

2025-11-04T16:52:48Z

For S3 on vangogh, PMFW needs to be notified before the driver powers down RLC. This already happens in smu_disable_dpms() so drop the superfluous call in amdgpu_device_suspend().

drm/amd: Stop overloading power limit with limit type

2025-10-13T18:14:35Z

When passed around internally the upper 8 bits of power limit include the limit type. This is non-obvious without digging into the nuances of each function. Instead pass the limit type as an argument to all applicable layers. Reviewed-by: Lijo Lazar Signed-off-by: Mario Limonciello Signed-off-by: Alex Deucher

drm/amd/pm: Add VCN reset support check capability

2025-08-15T17:04:25Z

This change introduces infrastructure to check whether VCN reset is supported by the SMU firmware. Key changes include: 1. Added new functions to query VCN reset support: - amdgpu_dpm_reset_vcn_is_supported() - smu_reset_vcn_is_supported() - pptable_funcs.reset_vcn_is_supported callback 2. Implemented proper locking in the DPM layer with mutex protection 3. Maintained consistency with existing SDMA reset support checks The new capability allows callers to check for VCN reset support before attempting the operation, preventing unnecessary attempts on unsupported platforms. v2: clean up debug info(Alex) Suggested-by: Alex Deucher Signed-off-by: Ruili Ji Signed-off-by: Jesse Zhang Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amdgpu: disable workload profile switching when OD is enabled

2025-06-03T19:04:24Z

Users have reported that they have to reduce the level of undervolting to acheive stability when dynamic workload profiles are enabled on GC 10.3.x. Disable dynamic workload profiles if the user has enabled OD.
