drm/amd/powerplay: fix null pointer dereference around dpm state relates

2019-08-25T14:10:30+00:00

[ Upstream commit 479156f2e5540077377a823eaf5a4263bd329063 ] DPM state relates are not supported on the new SW SMU ASICs. But still it's not OK to trigger null pointer dereference on accessing them.

drm/amdgpu: Check if SW SMU is supported before accessing funcs

2019-04-23T22:27:25+00:00

smu.ppt_funcs is only initialized for ASICs supporting SW SMU. On a Hawaii ASIC, attempting to access the udev attribute ATTRS{power_dpm_state} will cause a null pointer deref in amdgpu_get_dpm_state() because of this. Fix by checking if SW SMU is supported first. Signed-off-by: Leo Li Reviewed-by: Alex Deucher Reviewed-by: Huang Rui Signed-off-by: Alex Deucher

drm/amdgpu: support dpm level modification under virtualization v3

2019-04-10T18:53:27+00:00

Under vega10 virtualuzation, smu ip block will not be added. Therefore, we need add pp clk query and force dpm level function at amdgpu_virt_ops to support the feature. v2: add get_pp_clk existence check and use kzalloc to allocate buf v3: return -ENOMEM for allocation failure and correct the coding style Signed-off-by: Yintian Tao Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

Add feature_mask parameter for smu_upload_dpm_level as socclk, fclk and dcefclk have dependency, without feature_mask to point out specific clk will make it fail to set some clk.
