[PATCH xserver v2 20/22] xwayland: Add fallback timer for msc counting

When the compositor is not sending frame callbacks while we still wait on buffer release events fake a continuous msc counter with a timer. Having this timer is a prerequisite for queuing events. Signed-off-by: Roman Gilg <subd...@gmail.com> --- hw/xwayland/xwayland-present.

[PATCH xserver v2 21/22] xwayland: Implement queuing present vblanks

Queue present events to msc values. Fake msc events with a refresh rate of about 60fps when flips are not possible. When flips are executed rely on frame callbacks with a slow updating timer as fallback. This is important for applications, that want to limit their framerate. Signed-off-by: Roman

[PATCH xserver v2 01/22] present: Move screen flip functionality in separate file

Re: [PATCH xserver 1/2] present: cancel flip on reparenting

I'm a bit unsure on that one. I thought there is no cleanup code necessary in Present on a reparent because in theory the current Present code alone allows clients to flip arbitrary many child windows to a certain parent window as long as they have the same dimension as the parent. Of course a

Re: [RFC PATCH xserver] xwayland: Avoid assert failure in flips_stop()

Great detailed analysis in the backtrace! :) What confused me at first was that the present_wnmd_flips_stop function is called at all in this state because it should only be called when at least one flip has been done and in this case xwl_window->present_window must have been set to the
