Hello,
I have an application which must to synchronize with the vertical
synchronisation of my display.
To do this synchronization, I use a function of GLX (glXWaitVideoSyncSGI).
This function call the function DRM to wait the vertical synchronization
(drmWaitVBlank) and the driver (drm.ko)
Hi all,
I try to use the vertical synchronization on a program which use the functions
of openGL (glXWaitVideoSyncSGI), but the driver drm.ko does a wait
(DRM_WAIT_ON, function : drm_wait_vblank, file : drm_irq.c) on the crtc 0 and
does a wake up (DRM_WAKEUP) on the crtc 1 so, I haven't
