Subject: [PATCH 0509/2940] drm/amdgpu: Set the default value about gds vmid0
size
For sriov, when first run windows guest, then run linux guest, the gds
vmid0 size will be reset to 0 by windows guest. So if the value has been
reset to 0, then set the value to the default value in linux guest.
v2:
Fixed value instead of reading mmGDS_VMID0_SIZE.
v3:
Set the default value of the switch.
