Hello,
This is an attempt at simplifying the async page flip handling in VC4 in order to get rid of vc4_queue_seqno_cb() and its dependencies and rely on fences instead.
The reason I'm sending this as an RFC is because I'm pretty sure we can put some of the code added in patch 1 in drm_atomic_helper.c. Also, I'd like to have feedback from Padovan, Daniel and maybe others who have already thought about handling async page flips generically. And the last reason is that it's not been extensively tested, so it may not work correctly :-).
I'm certainly eager to see our custom async code die. Any KMS core folks want to comment on this proposal?
