The Cost Of ATI Kernel Mode-Setting On Fedora 12

[ Thanks to Michael Larabel for this link. ]

"Fedora has been shipping ATI kernel mode-setting support for the R500 series going back to the Fedora 10 release. ATI kernel mode-setting support did not appear in the mainline Linux kernel until recently when it entered the Linux 2.6.31 kernel as a staging driver, where it continues to remain today. Internally the ATI kernel mode-setting code is dependent upon TTM, which also entered the Linux 2.6.31 kernel. Kernel mode-setting and 3D support for the newer ATI R600/700 (Radeon HD 2000, 3000, 4000 series) has been actively under development for some months and can now be found in the "master" branches for most of the code repositories. However, this support is not enabled by default in Fedora 12 for the R600/700 series but will be with Fedora 13. Users though can easily enable R600/700 3D in Fedora 12, which has worked out well for many users. Fedora 12 is shipping with the Linux 2.6.31.5 kernel, X Server 1.7.1, xf86-video-radeon 6.12.99, and Mesa 7.7-devel."
