Linux 4.2 May Finish Fixing Up Radeon Audio Support
Since the Linux 4.0 kernel there has been DisplayPort audio support for the open-source Radeon driver. That DP audio handling came after a big rework to the audio code in the Radeon DRM kernel driver. A half-year later it looks like all the audio code is now cleaned up and ready.
Alex Deucher sent in a pull request today for landing more Radeon and AMDGPU driver fixes for the current Linux 4.2 cycle. He commented, "The audio fix ended up being more invasive than I would have liked, but this should finally fix up the last of the regressions since DP audio support was added."
The audio-related work is reworking audio detection in the DRM driver as well as reworking the audio mode-set to handle non-audio HDMI features.
Between the big audio fixes and other bug fixes to Radeon and AMDGPU, there's around 200 lines of code shifted around for this pull request. I've already done some AMDGPU tests on Linux 4.2 while I'll have some more Radeon Linux 4.2 tests soon. There's also the daily benchmarks of the kernel and Mesa that we do too.
