Summary
KMS support was new in 2.6.31, with 'stable' support for i915 based drivers, and unstable support for 2.6.32. 2.6.32 should bring Radeon 'stable' support. Nvidia support is expected to only be available via the Nouveau driver, which is currently not slated for inclusion currently.
We need to consider which of those technologies will be appropriate for Lucid.
Release Note
TBC
Rationale
User stories
Assumptions
Radeon KMS support is stable in time for release. Radeon mesa must be ready for KMS to be enabled.
Implementation
Radeon KMS support should be available in 2.6.32 and later covering the kernel versions which Lucid is likely to have. To enable testing we should enable Radeon KMS by default as early as possible in the cycle. Interlock with X required.
Nouveau support is not likley to be in .32 or .33. We may wish to look at nouveau patches for Lucid, if they are independant enough they may be worth providing test images for the X-edgers team against the lucid kernel early in the cycle to allow stability and card support to be evaluated. We should be scepticle of enabling this for release by default.
Unresolved issues
Potential for Legal encomberance on the Nouveau patches needs legal review before inclusion in a shipping product.
