David Airlie has pushed a horde of new code into his drm-next Git tree, which is what will get pulled into the Linux 2.6.32 kernel once the merge window is open. Most prominently, this new DRM code brings support for kernel mode-setting with R600 class hardware as well as 3D support. Of course, to benefit from those features, you will also need the latest libdrm, Mesa, and xf86-video-ati DDX code too.
Additionally, this code provides firmware loading support for the r128/mga/radeon + Radeon KMS drivers, the latest Intel drm-next code, Radeon R100/200 KMS command stream checking, Radeon KMS TV-Out support, merged FB handling for all KMS drivers, and DMT timings + better HDMI EDID decoding.
The announcement regarding this pull was made on David Airlie's blog
