[PATCH V5 09/16] drm/amd/pm: optimize the amdgpu_pm_compute_clocks() implementations
Evan Quan
evan.quan at amd.com
Mon Dec 13 03:52:16 UTC 2021
Drop cross callings and multi-function APIs. Also avoid exposing
internal implementations details.
Signed-off-by: Evan Quan <evan.quan at amd.com>
Change-Id: I55e5ab3da6a70482f5f5d8c256eed2f754feae20
--
v1->v2:
- add back the adev->pm.dpm_enabled check(Lijo)
