Created attachment 274677
--> https://bugzilla.kernel.org/attachment.cgi?id=274677&action=edit
dmesg log
Started getting these "[drm] Got external EDID base block and 0 extensions..."
messages with recent 4.14 kernels. Is this a bug or a configuration issue on my
part ?

That's an info level message from your use of the edid_firmware option. Been
there since 2012.

Yes thanks, the message is not new to me but the repeated loading of the
firmware edid blob does appear new to me. Why the repeated loading of the
firmware blob once should be sufficient ??

If I remove drm_kms_helper.edid_firmware=edid/hp_lp2065.bin from the kernel
boot line the messages go away and as far as I can seen no edid data is loaded
by the kernel is this the correct behaviour ?
thanks

--- Comment #6 from Jani Nikula (jani.nikula@intel.com) ---
The firmware EDID handling was moved at a lower level in the stack to be a more
transparent replacement for the display EDID. Without this, many features were
erroneously parsed from the display EDID, which was in conflict with the
firmware EDID.
This means that any time the driver would read the EDID, it gets loaded as the
firmware EDID.
It's arguably something that should be improved in the driver to not keep
reading the EDID so many times over, whether it's display or firmware EDID.

Thanks for the explanation, hopefully there will be an improvement in the
future.
