not seen.
In this patch ,disabling low memory P state only when video

This reverts commit dbd8299c32f6f413f6cfe322fe0308f3cfc577e8.
Reason for revert:
This patch sends msg PPSMC_MSG_DisableLowMemoryPstate(0x002e)
in wrong of sequence to SMU which is before PPSMC_MSG_UVDPowerON (0x0008).
This leads to SMU failing to service the request as it is

Apologies. We already have a fix for this on our internal amd-kfd-staging
branch, but it's missing from amd-staging-drm-next. I'll cherry-pick our fix to
amd-staging-drm-next and nominate it for drm-fixes.

Not a problem, I just saw the one missing patch when trying to rebase our KFD
branch. I'll just put it on there instead.

Sorry, something is still missing here. The new variable vram_base_offset isn't
used anywhere. We have some other changes in amd-kfd-staging to use that
vram_base_offset that are probably missing on amd-staging-drm-next. This change
won't have any effect as is.

Hmm, we should remove the PCIe portion of this change. We just added some extra
checks there on amd-kfd-staging that should make it closer to upstreamable. For
now, just handle the XGMI case, but return -EINVAL in the else-branch (for
other remote VRAM cases).

You changed the doorbell routing in NBIO. I think that won't work for SR-IOV,
because it's not controlled by the guest OS there. We may need to disable

This change is not suitable for amd-staging-drm-next. PCIe P2P was not enabled
