drm/amdgpu/gmc9: Adjust GART and AGP location with xgmi offset (v2)

2018-09-11T03:47:34Z

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 Acked-by: Slava Abramov Signed-off-by: Shaoyun Liu Signed-off-by: Alex Deucher Reviewed-by: Felix Kuehling Acked-by: Huang Rui
