The `intel` driver currently does not provide a way to pass arbitrary EDID. It would be nice to implement `CustomEDID` as done in radeon.
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.
