Hi Simon, I'm cc'ing André as he has been actively working on it lately and must be quite familiar with the async flip machinery. > > User-space patch: > https://github.com/Plagman/gamescope/pull/595 > > IGT patch: > https://patchwork.freedesktop.org/series/107681/ Also, André recently generalized the kms_async_flip to test drivers other than i915, so I think he can provide some thoughts about the IGT test too.
