H A D | amdgpu_rlc.h | 460c484f Thu Feb 27 07:17:40 CST 2020 Jacob He <jacob.he@amd.com> drm/amdgpu: Initialize SPM_VMID with 0xf (v2)
SPM_VMID is a global resource, SPM access the video memory according to SPM_VMID. The initial valude of SPM_VMID is 0 which is used by kernel. That means UMD can overwrite the memory of VMID0 by enabling SPM, that is really dangerous.
Initialize SPM_VMID with 0xf, it messes up other user mode process at most.
v2: squash in indentation fix
