2020-01-07drm/amdgpu/gmc10: use common invalidation engine helperAlex Deucher

2019-03-19drm/amdgpu: use ring/hash for fault handling on GMC9 v3Christian König
Further testing showed that the idea with the chash doesn't work as expected. Especially we can't predict when we can remove the entries from the hash again. So replace the chash with a ring buffer/hash mix where entries in the container age automatically based on their timestamp. v2: use ring buffer / hash mix v3: check the timeout to make sure all entries age Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> (v2) Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2018-09-10drm/amdgpu/gmc9: Adjust GART and AGP location with xgmi offset (v2)Alex Deucher
On hives with xgmi enabled, the fb_location aperture is a size which defines the total framebuffer size of all nodes in the hive. Each GPU in the hive has the same view via the fb_location aperture. GPU0 starts at offset (0 * segment size), GPU1 starts at offset (1 * segment size), etc. For access to local vram on each GPU, we need to take this offset into account. This including on setting up GPUVM page table and GART table v2: squash in "drm/amdgpu: Init correct fb region for none XGMI configuration" Acked-by: Huang Rui <ray.huang@amd.com> Acked-by: Slava Abramov <slava.abramov@amd.com> Signed-off-by: Shaoyun Liu <Shaoyun.Liu@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Acked-by: Huang Rui <ray.huang@amd.com>
