No; that would only wait as long as both drmmode_crtc->flip_pending and drmmode_crtc->scanout_update_pending are non-zero, i.e. while a TearFree flip is pending. But it needs to wait while a non-TearFree flip is pending as well (as the existing code did), and while a non-TearFree scanout update is pending (the case your patch fixes). Anyway, I've come to realize this isn't the right place to fix the problem, it should only be done when drmmode_crtc_scanout_free is called: if (drmmode_crtc->scanout[scanout_id].pixmap && fb != amdgpu_pixmap_get_fb(drmmode_crtc-> scanout[scanout_id].pixmap)) { drmmode_crtc_wait_pending_event(drmmode_crtc, pAMDGPUEnt->fd, drmmode_crtc->scanout_update_pending); drmmode_crtc_scanout_free(drmmode_crtc); } ...
