And in the direct-rendering case, this scheduler is not used for OpenGL. The client-side driver submits rendering commands directly to its kernel module. It is possible that some kernel modules perform some sort of scheduling, but none of the open-source drivers implement such a thing. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux)
