2022-06-21drm/amdgpu: Adjust logic around GTT size (v3)Alex Deucher1-6/+14
Certain GL unit tests for large textures can cause problems with the OOM killer since there is no way to link this memory to a process. This was originally mitigated (but not necessarily eliminated) by limiting the GTT size. The problem is this limit is often too low for many modern games so just make the limit 1/2 of system memory. The OOM accounting needs to be addressed, but we shouldn't prevent common 3D applications from being usable just to potentially mitigate that corner case. Set default GTT size to max(3G, 1/2 of system ram) by default. v2: drop previous logic and default to 3/4 of ram v3: default to half of ram to align with ttm v4: fix spelling in comment (Kent) Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1942 Reviewed-by: Marek Olšák <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

Loop through all VMIDs for gmc_v10_0_flush_gpu_tlb_pasid and gmc_v11_0_flush_gpu_tlb_pasid (only if using MES for gmc_v10). This is required for MES due to use_different_vmid_compute causing SDMA queues to be assigned different VMIDs than compute for the same PASID.

Create contexts applying AMDGPU_CTX_PRIORITY_HIGH which submits job to the high priority queue on GFX pipe1.
