+Subject: [PATCH 5053/5725] drm/amdgpu/sriov: give 8s for recover vram under
+ RUNTIME
+
+Extend the timeout for recovering vram bos from shadows on sr-iov
+to cover the worst case scenario for timeslices and VFs
+
+Under runtime, the wait fence time could be quite long when
+other VFs are in exclusive mode. For example, for 4 VF, every
+VF's exclusive timeout time is set to 3s, then the worst case is
+9s. If the VF number is more than 4,then the worst case time will
+be longer.
+The 8s is the test data, with setting to 8s, it will pass the TDR
+test for 1000 times.
