There is a bug found in vml2 xgmi logic:
mtype is always sent as NC on the VMC to TC interface for a page walk,
regardless of whether the request is being sent to local or remote GPU.
NC means non-coherent and will cause the VMC return data to be cached
in the TCC (versus UC – uncached will not cache the data). Since the
page table updates are being done by SDMA/HDP, then TCC will never be
updated and the GC VML2 will continue to hit on the TCC and never get
the updated page tables and result in a fault.
Heave weigh tlb invalidation does a WB/INVAL of the L1/L2 GL data
caches so TCC will not be hit on next request

New feature for RLC, some registers can be programmed by
RLC interface under SR-IOV VF:
WREG32_SOC15_RLC_SHADOW:
1, for GRBM_GFX_CNTL, firstly the new register value should be be
programmed to SCRATCH_REG2
1, for GRBM_GFX_INDEX, firstly the new register value should be be
programmed to SCRATCH_REG3
WREG32_RLC:
for registers supported to be programmed by RLC interface, the
following sequence should be used:
1, write the value to SCRATCH_REG0
2, write reg | 0x80000000 to SCRATCH_REG1
3, write 0x1 to RLC_SPARE_INT to notify RLC
4, polling SCRATCH_REG1 to check if finished

Issue ras enable/disable cmd without checking currect state.
Looks like ras TA will handle current state == target state case.
Now driver might need do a reset to satisfy ras TA.
