I see some activity in the mesa/drm tree I'm not actively working on it right now... Radeon is using TTM as the backend, while presenting a GEM api to userland. Nouveau will do the same thing. Via will also use the TTM backend, though I'm not certain how it will present to userland. I still haven't managed to get my hands on any VIA hardware, so I'm a bit out of the loop there. As far as KMS goes, I anticipate much of the code for Intel/Radeon/Nouveau to be fairly portable. The tricky part is figuring out how to hook it into our console rendering code, which I still don't fully understand. We will also need to figure out how to handle hardware that we don't have KMS support for. robert. > -Aditya > _______________________________________________ > freebsd-x11@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-x11 > To unsubscribe, send any mail to "freebsd-x11-unsubscribe@freebsd.org" --=20 Robert Noland <rnoland@FreeBSD.org> FreeBSD --=-muC9du/89rcvu0UHKoKX Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (FreeBSD) iEYEABECAAYFAkpfHVsACgkQM4TrQ4qfROOiXACfXkVppMOqh25ioNDOqEu6Lxmn MUsAn2MpW6mmPSdKuVbyZEnYpO6Fn1JR =3/an -----END PGP SIGNATURE----- --=-muC9du/89rcvu0UHKoKX--
