Clang warns: ../drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link.c:980:36: warning: address of 'sink->edid_caps.panel_patch.skip_scdc_overwrite' will always evaluate to 'true' [-Wpointer-bool-conversion] if (&sink->edid_caps.panel_patch.skip_scdc_overwrite) ~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~ 1 warning generated. This is probably not what was intended so remove the address of operator, which matches how skip_scdc_overwrite is handled in the rest of the driver. While we're here, drop an extra newline after this if block.

Seems to work reliably on VI+ except for a few so enable runpm barring those where baco for runtime power management is not supported. [rajneesh] Picked https://patchwork.freedesktop.org/patch/335402/ to enable runtime pm with baco for kfd. Also fixed a checkpatch warning and added extra checks for VEGA20 and ARCTURUS. Reviewed-by:

So far the kfd driver implemented same routines for runtime and system wide suspend and resume (s2idle or mem). During system wide suspend the kfd aquires an atomic lock that prevents any more user processes to create queues and interact with kfd driver and amd gpu. This mechanism created problem when amdgpu device is runtime suspended with BACO enabled. Any application that relies on kfd driver fails to load because the driver reports a locked kfd device since gpu is runtime suspended. However, in an ideal case, when gpu is runtime suspended the kfd driver should be able to: - auto resume amdgpu driver whenever a client requests compute service - prevent runtime suspend for amdgpu while kfd is in use This change refactors the amdgpu and amdkfd drivers to support BACO and runtime power management.
