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 Signed-off-by: Jacob He <jacob.he@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> |
