There's Evergreen KMS Support & More To Test

AMD

David Airlie has re-based his drm-radeon-testing tree and there's now a whole lot of new code and features that users can play with and test. The drm-radeon-testing tree is a branch of the Linux kernel and is code for the Radeon DRM area that will ultimately make it into the mainline tree in the Linux 2.6.34 kernel series and later.

To be found in drm-radeon-testing right now is new I2C code that supports the hardware I2C engines found on Radeon graphics cards and exposes it to user-space, a PLL algorithm rework, DRM power management support, basic Evergreen "R800" KMS support, and various other fixes and new additions.

Like the recent R800 Evergreen in xf86-video-ati DDX support, the kernel mode-setting support lacks IRQ and any acceleration (2D, 3D, X-Video) support at this time for these Radeon HD 5000 series products. The new I2C support can be in turn exploited for fan/thermal monitoring on select ATI graphics cards, among other uses.

The list of what can currently be found in drm-radeon-testing at the moment is shared on David Airlie's blog. Clone the drm-radeon-testing branch of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git to fetch the code.
