Open-Source ATI Evergreen Acceleration Builds Up
This morning though while our main server has been getting hammered, some new Evergreen code cleared legal review and has now been pushed out to the public. AMD's Alex Deucher has shown off kernel DRM code that adds support for the command processor, interrupts, and graphics initialization on the Evergreen ASICs. This code also comes with new microcode that's been released and is required for the code to function. Support for the power tables on Evergreen hardware has also been added in a later patch.
Alone this new code really isn't useful to end-users, but it begins laying the foundation for the acceleration support to arrive, which is what most Radeon HD 5000 owners are waiting for. Right now Evergreen users are stuck without any hardware acceleration or they must use the proprietary Catalyst driver on Linux.
The patch series adding this new Evergreen support to the kernel DRM can be found on the dri-devel mailing list. This code should make it into the Linux 2.6.35 kernel and hopefully with some usable 2D/X-Video support too, if not basic 3D support if that code and the Mesa driver are ready in time and have cleared AMD's legal review.
