drm/amd/pm: Fix output of pp_od_clk_voltage

2023-05-24T19:18:10+00:00

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: Fix incorrect comment about Vangogh power cap support

2023-04-11T22:03:44+00:00

The comment mentions that power1 cap attributes are not supported on Vangogh, but the opposite is indeed valid: for APUs, only Vangogh is supported. While at it, also fixed the Renoir comment below (thanks Melissa for noticing that!). Cc: Lijo Lazar Cc: Melissa Wen Signed-off-by: Guilherme G. Piccoli Signed-off-by: Alex Deucher
