drm/amdgpu: Prevent shift wrapping in amdgpu_read_mask()

2021-03-04T10:37:46+00:00

[ Upstream commit c915ef890d5dc79f483e1ca3b3a5b5f1a170690c ] If the user passes a "level" value which is higher than 31 then that leads to shift wrapping. The undefined behavior will lead to a syzkaller stack dump.

Revert "drm/amdgpu/swsmu: drop set_fan_speed_percent (v2)"

2021-02-03T22:28:39+00:00

commit a119f87b86bcdf14a18ce39a899e97a1e9160f7f upstream. On some boards the rpm interface apparently does not work at all leading to the fan not spinning or spinning at strange speeds. Revert this for now to fix 5.10, 5.11. The follow on patch fixes this properly for 5.12. This reverts commit 8d6e65adc25e23fabbc5293b6cd320195c708dca.

drm/amd/pm: do not use ixFEATURE_STATUS for checking smc running

2020-10-30T05:18:21+00:00

This reverts commit f87812284172a9809820d10143b573d833cd3f75 ("drm/amdgpu: Fix bug where DPM is not enabled after hibernate and resume"). It was intended to fix Hawaii S4(hibernation) issue but break S3. As ixFEATURE_STATUS is filled with garbage data on resume which can be only cleared by reloading smc firmware(but that will involve many changes). So, we will revert this S4 fix and seek a new way.
