<content type='text'>
commit 4fa944255be521b1bbd9780383f77206303a3a5c upstream.

Users of ttm entities need to hold the gtt_window_lock before using them
to guarantee proper ordering of jobs.

commit d3c7059b6a8600fc62cd863f1ea203b8675e63e1 upstream.

Otherwise an uninitialized value can be returned if
amdgpu_res_cleared returns true for all regions.

<content type='text'>
commit 2255b40cacc2e5ef1b127770fc1808c60de4a2fc upstream.

Vulkan can't support DCC and Z/S compression on GFX12 without
WRITE_COMPRESS_DISABLE in this commit or a completely different DCC
interface.

AMDGPU_TILING_GFX12_SCANOUT is added because it's already used by userspace.

[ Upstream commit e2e97435783979124ba92d6870415c57ecfef6a5 ]

The driver needs to set the correct max_segment_size;
otherwise debug_dma_map_sg() will complain about the
over-mapping of the AMDGPU sg length as following:

While moving buffer which has dcc tiling config, it is needed to restore
its original dcc tiling.

1. extend copy flag to cover tiling bits
2. add logic to restore original dcc tiling config
