[PATCH v2] drm/amdgpu: Default disable GDS for compute VMIDs

2019-07-17 Thread Greathouse, Joseph
The GDS and GWS blocks default to allowing all VMIDs to access all entries. Graphics VMIDs can handle setting these limits when the driver launches work. However, compute workloads under HWS control don't go through the kernel driver. Instead, HWS firmware should set these limits when a process is
