“The necessary DRM code for kernel mode-setting and 3D support
for the ATI R600/700 ASICs has landed in the Linux 2.6.32 kernel,
but that has been back-ported into Fedora’s 2.6.31 kernel. The Mesa
code for the Radeon DRI driver that has the R600/700 3D support has
been in Mesa’s master Git repository for some time, but that is not
enabled by default in Mesa 7.6. To enable the open-source R600/700
3D support under Fedora 12 one must simply run yum install
mesa-dri-drivers-experimental and then reboot their system. This
experimental DRI drivers package is derived from the Mesa 7.6
branch. For our testing we had done a clean installation of Fedora
12 Beta and then installed mesa-dri-drivers-experimental. The ATI
Radeon hardware we used for testing included a Radeon HD 4870,
Radeon HD 4650, and a Radeon HD 3870.”
