AMD Radeon KMS Gets Some DP Improvements

Comment On This Article

AMD's Alex Deucher has published a set of eighteen patches to the DRI development list that are primarily focused on fixing up the DisplayPort (DP) and Embedded DisplayPort (eDP) capabilities of the Radeon DRM/KMS driver in the Linux kernel.

The patch-set begins here on the list. This isn't as exciting as say when KMS page-flipping patches were pushed or other feature work along those lines, but with the growing presence of DisplayPort monitors and eDP on notebooks, the work should be quite visible now and going forward.

The patches have fixes for the AtomBIOS, spread spectrum fixes, DisplayPort clock programming for DCE4/DCE5 hardware, adjusted eDP handling, eDP panel power functions, new DisplayPort 1.2 registers, rewritten DisplayPort handling, etc.

These patches will likely be pulled into the DRM kernel tree shortly and then land in the Linux 2.6.40 kernel along with other Linux kernel DRM improvements to the Radeon driver as well as Nouveau and Intel driver improvements too.
