drm/amd/pm: Fix output of pp_od_clk_voltage

2023-05-30T13:03:19+00:00

commit 40baba5693b9af586dc1063af603d05a79e57a6b upstream. Printing the other clock types should not be conditioned on being able to print OD_SCLK. Some GPUs currently have limited capability of only printing a subset of these. Since this condition was introduced in v5.18-rc1, reading from `pp_od_clk_voltage` has been returning empty on the Asus ROG Strix G15 (2021).

drm/amd/pm: Init pm_attr_list when dpm is disabled

drm/amd/pm: Remove redundant check condition

2022-09-19T19:17:58+00:00

V3: [Why]: Since ASICs using smu v13_0_2 have called smu .suspend before calling amdgpu_pm_sysfs_fini, pm.dpm_enabled was already set to 0 when smu .suspend was called. This makes it impossible to delete all pm sys nodes. [How]: Since all functions in amdgpu_pm_sysfs_fini have their own condition checks, so the first conditional check in amdgpu_pm_sysfs_fini can be removed.
