I've tested these two patches on top of Linux v5.2-rc3 and the EDID override works correctly on an Intel Ironlake GPU with a monitor that lost its EDID a while ago.
While testing I noticed a couple of things:
While everything the GUI is the correct resolution, GNOME is unable to identify the monitor vendor or model. This is a regression from the previous edid override functionality. It looks like this is because the edid file in /sys is not populated with the EDID override data.
Right, I've added a call to drm_connector_update_edid_property() in v2 to address this issue.
I got a crash due to null pointer dereference at one point, I'll try to track down when this happens.
Can't think of why this would happen; the backtrace might offer clues.
Thanks for testing!
