Can you give some indication as to what > is involved? Involved in what sense ? Basically, you take the Linux sources, drivers/gpu/drm/radeon/* and makes them compilable, runnable and then bug-free under FreeBSD. In the course of actions, you add the missed infrastructure bits from drivers/gpu/drm/*. The most infrastructure parts needed for the KMS are already ported in my kms git branch. Biggest missed stuff is TTM, but I already promised to do it if somebody takes care of the radeon. The line count for radeon driver is ~100KLOC, that is twice as big as Intel driver. I am optimistic that the porting will take 3-4 months, judging after the Intel experience. Also, I am more then willing to help, but definitely won't do it myself. --vtjqwL8hBMlo2PUA Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAk6v3jwACgkQC3+MBN1Mb4ie4gCgqYAB4iK1aZAhGn+iK71wQOWq cqkAn0yMCQCNS0JJimgKJJWQJEiDB2V2 =8KBh -----END PGP SIGNATURE----- --vtjqwL8hBMlo2PUA--
