2022-07-05drm/amd/display: Switch to correct DTO on HDMIChris Park2-0/+6
[Why] For Pixel Rate control, when on HDMI, HDMI DTO should be selected instead of DP DTO. [How] Pass HDMI parameter for HDMI stream, and select correct DTO.

2022-07-05drm/amd/display: Change DET policy for MPO casesAlvin Lee2-14/+22
For MPO we want to allocate less than maximum DET for MPO pipes because we need enogh buffer to move DET back to other pipes when removing an MPO plane. Also update regular DET allocation to use DET override (DCN32 has an internal policy which driver does not want to use) Signed-off-by: Alvin Lee <Alvin.Lee2@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2022-07-05drm/amd/display: Use two pixel per container for k1/k2 divRodrigo Siqueira1-4/+4
Currently, we check if pixel_encoding is equal to PIXEL_ENCODING_YCBCR422 to get the k1/k2 div parameters. This commit changes this logic slightly by checking if two pixels per container are used.

2022-07-05drm/amd/display: Apply ODM 2:1 policy for single display configurationSamson Tam10-7/+83
[Why] Most of the time, a single display uses the ODM combine. When using multi-display, we use ODM combine only if it is necessary. These cases are not flexible enough for us, and we can improve them to take advantage of our hardware. We want to have more control over the ODM policy. [How] This commit add a new debug flag named enable_single_display_2to1_odm_policy to control the ODM policy and another flag named enable_dp_dig_pixel_rate_div_policy to fine control the ODM combine. This is possible by adding a new "pipe.dest" parameter that can be set to ODM 2:1 combined if we use a single display. For dynamic ODM combine, when using DP-DIG, DCN applies K2=2 settings for ODM combine. Note that this feature affects the following registers: - timing.pix_clk_100khz -> DP_VID_M, DP_VID_N - requested_pix_clk_100hz -> DP_DTOn_PHASE - OTGn_PIXEL_RATE_DIVK2 - DP_PIXEL_PER_CYCLE_PROCESSING_MODE - DIG_FIFO_OUTPUT_PIXEL_MODE - DP_VID_N_MUL Acked-by: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Signed-off-by: Samson Tam <Samson.Tam@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

We don't need to validate and map root PD specially here, it would be validated and mapped by amdgpu_vm_validate_pt_bos if it is evicted. The special case is when turning a GFX VM to a compute VM, if vm_update_mode changed, we should make sure root PD gets mapped. So just map root PD after updating vm->update_funcs in amdgpu_vm_make_compute whether the vm_update_mode changed or not. v3: - Add some comments suggested by Christian. v2: - Don't rename vm_validate_pt_pd_bos and make it public.

2022-06-28drm/amdgpu: Follow up change to previous drm scheduler change.Andrey Grodzovsky4-11/+29
Align refcount behaviour for amdgpu_job embedded HW fence with classic pointer style HW fences by increasing refcount each time emit is called so amdgpu code doesn't need to make workarounds using amdgpu_job.job_run_counter to keep the HW fence refcount balanced. Also since in the previous patch we resumed setting s_fence->parent to NULL in drm_sched_stop switch to directly checking if job->hw_fence is signaled to short circuit reset if already signed.

2022-06-28drm/amdgpu: Prevent race between late signaled fences and GPU reset.Andrey Grodzovsky3-0/+23
Problem: After we start handling timed out jobs we assume there fences won't be signaled but we cannot be sure and sometimes they fire late. We need to prevent concurrent accesses to fence array from amdgpu_fence_driver_clear_job_fences during GPU reset and amdgpu_fence_process from a late EOP interrupt. Fix: Before accessing fence array in GPU disable EOP interrupt and flush all pending interrupt handlers for amdgpu device's interrupt line. v2: Switch from irq_get/put to full enable/disable_irq for amdgpu Signed-off-by: Andrey Grodzovsky <andrey.grodzovsky@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2022-06-28drm/amdgpu: Add put fence in amdgpu_fence_driver_clear_job_fencesAndrey Grodzovsky1-1/+3
This function should drop the fence refcount when it extracts the fence from the fence array, just as it's done in amdgpu_fence_process.
