Hi Michel & pekka >>Yes, drm_handle_vblank must be called before drm_crtc_send_vblank_event, >>otherwise it's not surprising that the timestamp in the event is wrong. :) Yes. our code call drm_crtc_send_vblank event first. The orignal fps is 60, but if I swap the order of drm_crtc_send_vblank_even

Re: unique id for wayland objects

Hi pekka I'm not familiar with kernel. I know part of drm driver is implement by ourself. I check the vblank callback function, it sends pageflip event first if there is a frame complete, update vblank timestamp later. I don't know why the owner write code like this. but if I swap the code order,

Re: unique id for wayland objects

Hi pekka I debug the presentation time recently. I have checked each user call drmAtomicCommit get the corresponding pageflip event. But some presentation results (c2p) are a little weird. They are 1~5ms or -1 ~ -5 ms. some results are normal(8 ~ 20 ms). I used to explain the weird result is becau
