Weston will not repaint until previous update has been acked by a pageflip event coming from the drm driver. However, some buggy drivers won’t return those events or will stop sending them at some point and Weston output repaints will completely freeze. To ease developers’ task in testing their drivers, this patch makes compositor-drm use a timer to detect cases where those pageflip events stop coming. This timeout implementation is software only and includes basic features usually found in a watchdog. We simply exit Weston gracefully with a log message and an exit code when the timout is reached. The timeout value can be set via weston.ini by adding a pageflip-timeout=<MILLISECONDS> entry under [core] section. Setting it to 0 disables the timeout feature. v2: - Made sure we would get both the pageflip and the vblank events before stopping the timer. - Reordered the error and success cases in drm_output_pageflip_timer_create() to be more in line with the rest of the code. v3: - Reordered (de)arming of the timer with the code around it to avoid it being rearmed before the current dearming. - Return the proper value for the dispatcher in the pageflip_timeout callback. - Also display the output name in case the timer fires. v4: - Reordered a forgotten timer rearming after its drmModePageFlip().
