drm/amd/pm: Use pm_display_cfg in legacy DPM (v2)

2026-03-25T10:08:46+00:00

commit 9d73b107a61b73e7101d4b728ddac3d2c77db111 upstream. This commit is necessary for DC to function well with chips that use the legacy power management code, ie. 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.

drm/amd/pm: Remove legacy interface for xgmi plpd

2024-05-17T21:40:39+00:00

Replace the legacy interface with amdgpu_dpm_set_pm_policy to set XGMI PLPD mode. Also, xgmi_plpd_policy sysfs node is not used by any client. Remove that as well. Signed-off-by: Lijo Lazar Reviewed-by: Hawking Zhang Reviewed-by: Asad Kamal Acked-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amd/pm: Add support for DPM policies

2024-05-17T21:40:38+00:00

Add support to set/get information about different DPM policies. The support is only available on SOCs which use swsmu architecture. A DPM policy type may be defined with different levels. For example, a policy may be defined to select Pstate preference and then later a pstate preference may be chosen.

drm/amdgpu: optimize RLC powerdown notification on Vangogh

2023-11-29T21:48:58+00:00

The smu needs to get the rlc power down message to sync the rlc state with smu, the rlc state updating message need to be sent at while smu begin suspend sequence , otherwise SMU will crash while RLC state is not notified by driver, and rlc state probally changed after that notification, so it needs to notify rlc state to smu at the end of the suspend sequence in amdgpu_device_suspend() that can make sure the rlc state is correctly set to SMU.
