That would probably be a no-go, but we could enhance the kernel driver
to update the RLC_SPM_VMID register with the reserved VMID.

amdgpu_vm_reserve_vmid doesn’t return the reserved vmid back to user
space. There is no chance for user mode driver to update RLC_SPM_VMID.
Thanks

Christian is right here, that will cause many problems for simp

[WHY]
When SPM trace enabled, SPM_VMID should be updated with the current
vmid.
[HOW]
Add a chunk id, AMDGPU_CHUNK_ID_SPM_TRACE, so that UMD can tell us
which job should update SPM_VMID.
Right before a job is submitted to GPU, set the SPM_VMID accordingly.
