but into the file src/mesa/drivers/dri/i915/intel_ioctl.c, the function intelPageFlip
has it's body commented
/* Flip the front & back buffes
*/
void intelPageFlip( const __DRIdrawablePrivate *dPriv )
{
#if 0
...
#endif
}
apparently the kernel 2.6.16 has the ioctl for
intel drm page flip.
Taking into account that intel graphics cards
are shared memory, so they don't have the bandwith
of other gpu's the glSwapBuffers can take a
precious time to finish if pageFlip is not
available.
What's left to finish this functionality?
I'm willing to do all necessary tests and more
if possible.
