Bringing HDMI To ATI Kernel Mode-Setting

While the Linux 2.6.31 kernel brought initial support for ATI kernel mode-setting support with graphics cards up through the ATI Radeon X1000 series (and the Radeon HD 2000/3000/4000 support coming with the Linux 2.6.32 kernel), the KMS driver is not complete. There is still a fair amount of work ahead when it comes to in-kernel power management, and other areas, including HDMI support. Fortunately though, the HDMI support for ATI kernel mode-setting is moving along.

Christian König, who previously worked on HDMI audio support for the RadeonHD driver, has ported the High-Definition Multimedia Interface support to the kernel mode-setting driver. This HDMI audio support for the kernel is for the Radeon HD 2000 (R600) series and later. This patch that weighs in at just over 1,000 lines should work, but there are still a few areas that Christian is looking to improve upon with this support.

For those interested in Christian's mailing list announcement or to use this ATI KMS HDMI patch against the latest DRM code, drop by the dri-devel mailing list.
