The DRM Pull Request For The Linux 2.6.39 Kernel
David Airlie has just emailed Linus Torvalds with his main DRM (Direct Rendering Manager) pull request for the Linux 2.6.39 kernel that 2.6.38 was released earlier this week. As was mentioned a few days ago, the Linux 2.6.39 kernel will feature a number of interesting changes to the open-source graphics drivers, among other areas.
When it comes to the Radeon DRM driver in Linux 2.6.39, the main addition this time around is the Cayman GPU support. AMD published the patches earlier this month for Radeon HD 6900 series open-source support in the DRM/KMS driver, but there is currently no 2D/3D/video acceleration support with this code. For the R600 series, there is now tiling support that's enabled (it's already been this way for R300~R500 ASICs) along with predication support.
