The DRM was guilty for some time of needlessly mapping all of your card's framebuffer, but that should have been fixed a few months ago. Default AGP aperture size is chosen by the BIOS, on the other hand. I'm really glad John's dealing with this, since it was likely a major stability issue on newer hardware (i915 has either a 128MB or 256MB aperture, for example). --=20 Eric Anholt eta@lclark.edu http://people.freebsd.org/~anholt/ anholt@FreeBSD.org --=-vrOj3rXN6WE8mb5d4Roe Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (FreeBSD) iD8DBQBDqGpSHUdvYGzw6vcRAg5bAJ4kxHZYhYPhFqndbKp8EED6uogDRwCfSU9l m+2roSYgsnlbW2ePjmi5Eaw= =fnU6 -----END PGP SIGNATURE----- --=-vrOj3rXN6WE8mb5d4Roe--
