stable inclusion from stable-5.10.50 commit a8e85ed08858d0f34b20e5a8cc8063b2e34e019d bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ 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
