I discussed with Alex Deucher, one of the maintainer of the Radeon driver, about reclocking in the Radeon driver. He said that everything was contained in the driver itself. It didn't depend on facilities provided by Linux. Beside that, I don't know much. >>> Am I the only one with the impression that FreeBSD is so way behind >>> just because of this approach? >> >> Currently, we don't have a real method, we mainly lacked dedicated >> maintainer(s).

For the coming days, this mailing-list is fine, because I won't have much time on IRC. Plus, it's archived. But feel free to join #freebsd-xorg on EFnet whenever you want! I will be happy to discuss if I can. To experiment with working as a team on the kernel video drivers, I would love to receive some help to debug the drm-i915-update-38 branch. Some users get regressions compared to HEAD: I really want those to be fixed so I can commit the branch to HEAD and move forward with the next update. At this point, I don't really care about Haswell stability: important bug fixes are in Linux 3.9, thus we should update DRM again quickly instead of spending time to debug something which could be fixed already. Thank you for showing interest! --=20 Jean-S=C3=A9bastien P=C3=A9dron --bA8PtgiunMIWwMmNqa0KnOaQNUihikqB5 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQJ8BAEBCgBmBQJWgcjsXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ2NzA4N0ZEMUFFQUUwRTEyREJDNkE2RjAz OUU5OTc2MUE1RkQ5NENDAAoJEDnpl2Gl/ZTMPYYP/300O5Ifjrj3mzH1s2pdY5JO ILmdgZ83Cz9msQy+n8R69qpxdT5u2yBYZrivVOAi27YJEBInSew9meQBnFgEFEAo HrrTYf9L1U4y/iACzstHNwVxUlpo+MGVcifc8BCkXuNtm7LJgwnKbjWHvc47oAd1 ZcHgjMKzObB1MjmaEhKrKtX7U+TahHpacAYIOZKY8OLapNBS7z4x1PkBTKvNRS3I LcxSc41MmKKn4njm/7LOy8j1NXbno7fn1SvzHjpTt/+2J5JVDtVLUyvlry8LVglJ crvN51nIfSYkJHQ6mfIp/d2LgxIaHjKVTeRxD3HFtY0fJO+grxFtThIdKDkDSbau 994xEnASy+rdwfapiyVH2Z8zYAerkE6cR78biub8V17K7XiKOK0paXfqaAxM5KEy YY8rIEfTIZDAOzzEDCrej8SXMFAHE/rC+HpvTU4SA0FHD59a3Oh7CCCOIdLI8Am6 vgRAh9JXqHL94ZDMX1K/Qxf5d9gYdy45AmI706oWk7U0aVci40x0GxA5XJOAqLQV nGimpTFiroJbewBfLViiH3zy+3rqTRDfc5uT7kodZogOXZNvjk05xRnbFuTtM4bD SjO/ENngMQVnQOmeOiiz59PWrEjHkYAKJR1uYVkEJAaYXXLEORr/EKNEr9zzV8PT fTDvFylFRx5vSWKsaRw2 =wBXP -----END PGP SIGNATURE----- --bA8PtgiunMIWwMmNqa0KnOaQNUihikqB5--
