In fact, most of my recent work to enable DRI on PCI Matrox cards focused on exactly that. The code in mga_do_dma_bootstrap (and friends) is a good model (IM-not-so-HO!) for where the other DRMs should go. Basically, user-mode should say to the kernel, "Please initialize yourself with these tunable parameters." The kernel should then do whatever it wants and let user-mode know what it did. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (MingW32) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFCs5JqX1gOwKyEAw8RAhKjAJkBSErmFwfgBMX2/3AJv1eJ+FQVWQCgltBk S/0UJ5ThmMPV7XXX+QBjXz0= =wny5 -----END PGP SIGNATURE----- ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
