Based on a hunch I tested the following commit on my gen2: commit d435829ae9702c9f777b68227e43eafd702a8031 Author: Damien Lespiau <damien.lespiau@intel.com> Date: Wed Feb 5 17:14:12 2014 +0000 kms_cursor_crc: Port the test to the new modeset API Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> and it does look like the culprit. My gen4 still seems to pass, so the problem might be related to the limited pipe->LVDS/VGA connection options on gen2. Assigning this one to Damien. Oh my, that means I need to setup the PNV I have around. Simply restrict lvds/edp to pipe B for testing ;-) I think I don't handle correctly the error when the encoder doesn't have the pipe in possible_crtcs in that new code. I believe this should be fixed by this: commit a461515b334ebb7782ee15e31f943e7a6753d845 Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Fri Apr 25 15:27:57 2014 +0300 kms_cursor_crc: Fix the test on platforms where the pipe->port mapping has restrictions Please re-test. It has been fixed. Verified.Fixed. Closing old verified. |
