[PATCH 0/4] Improve logging for DP link training

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We do not currently output enough information to help debugging DP link
training issues. For e.g., training pattern and link status information.
This series aims to correct that by adding debug messages that can help
developers.

Dhinakaran Pandiyan (4):
  drm/i915/dp: Add debug messages to print DP link training pattern
  drm/i915/dp: Switch to using the DRM function for reading DP link
    status
  drm/dp: Clarify clock recovery and channel equalization failures
  drm/i915/dp: Dump DP link status when link training stages fails
