Created attachment 114978 [details] [review] drm/i915/dp: do not touch audio on port a IVB cpu eDP ctl register appears to have alternate scrambler reset in place of the audio enable bit. Please try the attached patch. It's not the final solution, but something for starters. Tested the patch and the warning is gone. Thanks, I'll need to think about a minimal fix for stable, and a broader fix for eDP in general. Another version, hopefully final... Chris, may I bother you for a re-test of this one please? http://patchwork.freedesktop.org/patch/48568 Sure. I booted with the new patch, and the warning is gone. (In reply to Chris Bainbridge from comment #6) > Sure. I booted with the new patch, and the warning is gone. Many thanks for the report and all the testing! Fixed by commit 9fcb1704d1d51b12e2f03c78bca013d0cbbb7c98 Author: Jani Nikula <jani.nikula@intel.com> Date: Tue May 5 16:32:12 2015 +0300 drm/i915/dp: there is no audio on port A in drm-intel-fixes, headed for v4.1 and cc: stable. |
