drm/amd/display: Add DC Debug mask to disable features for bringup

2020-05-21T16:37:19Z

[Why] At bringup we want to be able to disable various power features. [How] These features are already exposed as dc_debug_options and exercised on other OSes. Create a new dc_debug_mask module parameter and expose relevant bits, in particular * DC_DISABLE_PIPE_SPLIT * DC_DISABLE_STUTTER * DC_DISABLE_DSC * DC_DISABLE_CLOCK_GATING Signed-off-by: Harry Wentland Reviewed-by: Nicholas Kazlauskas Signed-off-by: Alex Deucher

drm/amdgpu: Add a UAPI flag for user to call mem_sync

2020-05-18T15:24:21Z

When this flag is set in the CS IB flags, it causes a memory cache flush of the GFX. v2: Move new flag to drm_amdgpu_cs_chunk_ib.flags Bump up UAPI version Remove condition on job != null to emit mem_sync Signed-off-by: Andrey Grodzovsky Reviewed-by: Luben Tuikov Signed-off-by: Alex Deucher

drm/amdgpu: fix runpm logic in amdgpu_pmops_resume

2020-05-08T18:33:27Z

We should be checking whether the driver enabled runtime pm rather than whether the asic supports BOCO or BACO. That said in general they are equivalent unless the user has disabled runpm or it has been disabled for a specific asic. Reviewed-by: Evan Quan Signed-off-by: Alex Deucher

drm/amdkfd: Enable GWS based on FW Support

2020-04-28T20:20:30Z

Rather than only enabling GWS support based on the hws_gws_support modparm, also check whether the GPU's HWS firmware supports GWS. Leave the old modparm in place in case users want to test GWS on GPUs not yet in the support list. v2: fix broken syntax from the first patch.

drm/amdgpu: add tmz feature parameter (v2)

2020-04-28T20:20:28Z

This patch adds tmz parameter to enable/disable the feature in the amdgpu kernel module. Nomally, by default, it should be auto (rely on the hardware capability). But right now, it need to set "off" to avoid breaking other developers' work because it's not totally completed. Will set "auto" till the feature is stable and completely verified. v2: add "auto" option for future use. Signed-off-by: Huang Rui Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: release drm_device after amdgpu_driver_unload_kms

If we release drm_device before amdgpu_driver_unload_kms, then it will raise the error below. Therefore, we need to place it before amdgpu_driver_unload_kms.
