Subject: drm/amdgpu/gmc6: Cache VM fault info
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=61673efc1f5b883ecbeaf7957c5594b70015572b;p=thirdparty%2Fkernel%2Flinux.git

drm/amdgpu/gmc6: Cache VM fault info

Call amdgpu_vm_update_fault_cache on GMC v6 similarly to how we
do in GMC v7-v8 so that VM fault info can be used later by
userspace for debugging.
