We'll also read out the state of all planes, so that we know which planes really need to be diabled. Additonally we change the plane<->pipe mapping sanitation to work by simply disabling the offending planes instead of entire pipes. And we do it before we otherwise sanitize the crtcs, which means we don't have to worry about misassigned planes during crtc sanitation anymore. v2: Reoder patches to not depend on enum old_plane_id v3: s/for_each_pipe/for_each_intel_crtc/ Cc: Thierry Reding <<a href="mailto:thierry.reding@gmail.com">thierry.reding@gmail.com</a>> Cc: Alex Villacís Lasso <<a href="mailto:alexvillacislasso@hotmail.com">alexvillacislasso@hotmail.com</a>> Bugzilla: <a class="bz_bug_link bz_status_CLOSED bz_closed" title="CLOSED DUPLICATE - Massive screen corruption on KMS startup under kernel-PAE-4.13.4-200.fc26.i686 in Acer Aspire One ZG5" href="show_bug.cgi?id=103223">https://bugs.freedesktop.org/show_bug.cgi?id=103223</a> Reviewed-by: Daniel Vetter <<a href="mailto:daniel.vetter@ffwll.ch">daniel.vetter@ffwll.ch</a>> Tested-by: Thierry Reding <<a href="mailto:thierry.reding@gmail.com">thierry.reding@gmail.com</a>> Link: <a href="https://patchwork.freedesktop.org/patch/msgid/20171117191917.11506-3-ville.syrjala@linux.intel.com">https://patchwork.freedesktop.org/patch/msgid/20171117191917.11506-3-ville.syrjala@linux.intel.com</a> Signed-off-by: Ville Syrjälä <<a href="mailto:ville.syrjala@linux.intel.com">ville.syrjala@linux.intel.com</a>> (cherry picked from commit b1e01595a66dc206a2c75401ec4c285740537f3f) Signed-off-by: Jani Nikula <<a href="mailto:jani.nikula@intel.com">jani.nikula@intel.com</a>> Attached is the bisect log. I don't really know how to go from here. I tried reverting that commit on top of the current master, but that leads to merge conflicts. I tried to solve them, but did not succeed, because too much has changed. Hope someone else can pick it up from here. But let me know if you need some more info or if I need to test something.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
