[ Upstream commit 75156a887b6cea6e09d83ec19f4ebfd7c86265f0 ]
The SVGA3dCmdDXGenMips command uses a shader-resource view to access
the underlying surface. Normally accesses using that view-type are not
dirtying the underlying surface, but that particular command is an
exception.
Mark the surface gpu-dirty after a SVGA3dCmdDXGenMips command has been
submitted.
This fixes the piglit getteximage-formats test run with
SVGA_FORCE_COHERENT=1
Fixes: a9f58c456e9d ("drm/vmwgfx: Be more restrictive when dirtying resources")
