This already happens in smu_disable_dpms() so drop the superfluous call in amdgpu_device_suspend().

SI and KV. Communicate display information from DC to the legacy PM code. Currently DC uses pm_display_cfg to communicate power management requirements from the display code to the DPM code. However, the legacy (non-DC) code path used different fields and therefore could not take into account anything from DC. Change the legacy display code to fill the same pm_display_cfg struct as DC and use the same in the legacy DPM code. To ease review and reduce churn, this commit does not yet delete the now unneeded code, that is done in the next commit. v2: Rebase. Fix single_display in amdgpu_dpm_pick_power_state.

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 <alexander.deucher@amd.com> Signed-off-by: Ruili Ji <ruiliji2@amd.com> Signed-off-by: Jesse Zhang <Jesse.Zhang@amd.com> Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> 2025-08-06T18:20:34+00:00 Asad Kamal asad.kamal@amd.com 2025-08-01T17:48:09+00:00 urn:sha1:83953ec1fedf37b900bded05ced31e6b7858cca3 Add dpm interface to get gpuboard/baseboard temperature metrics v2: Add temperature metrics support check(Lijo) v3: Return error code in case of operation not supported(Lijo) Signed-off-by: Asad Kamal <asad.kamal@amd.com> Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> 2025-06-03T19:04:24+00:00 Alex Deucher alexander.deucher@amd.com 2025-05-27T14:13:31+00:00 urn:sha1:5cccf10f652122a17b40df9d672ccf2ed69cd82f 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.
