5677c52090 drm/amdgpu/gmc10: use common invalidation engine helper 
Rather than open coding it.  This also changes the free masks
to better reflect the usage by other components.

c1a8abd99d drm/amdgpu: use ring/hash for fault handling on GMC9 v3 
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

6fdd68b14a drm/amdgpu/gmc9: Adjust GART and AGP location with xgmi offset (v2) 
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"
