Hi guys, The *_vm_flush functions on Vega10 insert an extra register wait before writing to the request register. That doesn't looks like it makes any sense to me and I think it is just a leftover from bringup.
The sequences is based on internal MM doc for UVD/VCE vm flush. Not sure how firmware handling all the writes, if the write sequence happens exactly in order, the first wait should be useless.
Now it's in the way of cleaning up the *_vm_flush functions into something common. So can we remove it?
Let me confirm with them first. Regards, Leo
Thanks, Christian.
