[RFC] Repurpose reserved field in vblank event to crtc_id

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Right now, if an atomic commit sends multiple vblank events it is not
possible to distiguish for each crtc each event is for in userspace.
This series changes that be repurposing the reserved field in struct
drm_event_vblank.

Would this be a sane thing to do?

Thanks,
Ander
