Just noticed this when I updated my branch and tried to unblank the display on my Bayley Bay platform. dmesg says: [ 626.549976] [drm:intel_dp_complete_link_train] *ERROR* failed to update link training I already tried reverting the vdd force change, no help there. Maybe the fast & wide commit?
Did you try i915.power_well_disable=0 ? That support just went in and has an effect on the unblank path..
Jesse, please try with http://mid.gmane.org/1394233524-3522-3-git-send-email-przanoni@gmail.com And obviously without the fast & wide one too.
Jesse, is this still an issue?
I think Jesse has patches for byt DP failures ...
No longer an issue, even after we abuse some of the DPMS bits.
Closing resolved+fixed with verification done by Jesse. Fix done with Revert included in commit 24f3e09.
