We only need one X.org 2D and one Mesa 3D driver for each card, but DRI supports as many rendering APIs as you like, including XvMC which offers accelerated video decode on top of DRI as well. So, the answer is that yes, at this point, we have only the two Intel integrated graphics drivers using GEM, but also no, the interface can support as many drivers as you want. I hope that GEM will encourage more graphics API research as it allows multiple user-space APIs to talk to the same underlying hardware resources. --=20 keith.packard@intel.com --=-2oOhEfuwxg8GmAPUuIZR Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iD8DBQBIk1HmQp8BWwlsTdMRAhyJAKCuFvQpgXcXxjDb1wwvY17NSM1g4gCgjtqV je76tTWJnKnDn/49YV5vNeU= =Hd+D -----END PGP SIGNATURE----- --=-2oOhEfuwxg8GmAPUuIZR-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
