And it's for a sure a lot of work. I'm interested in helping with the winsys/wayland bits, assuming the following: - We are pretty confident that drm_syncobj won't be superseded by something else in the near future. It seems to me like a lot of effort has gone into plumbing sync_file stuff all over, and it already needs replacing (I mean, it'll keep working, but we have a better replacement now. So compositors which have decided to ignore explicit sync for all this time won't have to do the work twice.) - Plumbing drm_syncobj solves the synchronization issues with upcoming AMD hardware, and all of this works fine in cross-vendor multi-GPU setups. - Someone is willing to spend a bit of time bearing with me and explaining how this all works. (I only know about sync_file for now, I'll start reading the Vulkan bits.) Are these points something we can agree on?
