This patchset adds support for evergreen+ based NI asics (Barts, Turks, and Caicos). It includes full acceleration (2D and 3D) for these asics. Mesa 7.10 or git master and xf86-video-ati from git master are required. There is no support for UMS, KMS is required.
The 3D engine on Barts, Turks, and Caicos is based and evergreen and is programmed similarly. The big change is the display block (DCE5) which includes new features such as improved color correction, HDMI 1.4a, and DP 1.2.
New ucode is required and is available here: http://people.freedesktop.org/~agd5f/radeon_ucode/ The vbios no longer loads the MC (memory controller) ucode during asic init, so the driver now has to load it.
Support for Cayman (Radeon HD 69xx asics) is in progress, but not yet ready for release.
