Description Mathieu Malaterre 2016-11-14 13:49:01 UTC 
The `intel` driver currently does not provide a way to pass arbitrary EDID. It would be nice to implement `CustomEDID` as done in radeon.
Comment 1 Mathieu Malaterre 2016-11-14 13:50:12 UTC 
For reference the radeon implementation is here:

It too is called Option "CustomEDID" in -intel. Note that since we cannot actually override the edid in the kernel, we do not in effect attach a new edid (changing how the driver talks to the monitor, or being able to setup audio channels etc), we just use it to generate modelines.

How about using drm_kms_helper.edid_firmare module parameter?

Indeed this is just fine. Thanks.
