Tested that patch you sent. Together with this patch it also resolves
the virtio gpu graphical display issue for SEV guest.
Is there a way to optimize the dma_sync_sg to only sync on the pages
being updated instead of all the pages in the obj sgl list every ti
t, for dma sync.

I sent the patch. For now it does dma_sync_sg on the pages in
TRANSFER_TO_HOST_2D/3D when use_dma_api is true.

With virtio gpu ttm-pages being dma mapped, dma sync is needed when
swiotlb is used as bounce buffers, before TRANSFER_TO_HOST_2D/3D
commands are sent.

before sending
VIRTIO_GPU_CMD_RESOURCE_FLUSH
and VIRTIO_GPU_CMD_SET_SCANOUT, still blank black screen after display manger
is kicked off.
Do you know which path I'm still missing as far as VIRTIO_GPU_CMD goes?
Thanks

ristian is suggesting to map and set ttm->pages as
decrypted
right after ttm->pages are allocated.
Just checking with you guys maybe there is a better way to handle this in
the virtio gpu layer instead of the common ttm layer. Could you guys shine some
light on this? Thanks.

Framebuffer memory needs to be accessed decrypted. Ensure the
memory encryption mask is not set for the ttm framebuffer mappings.
