I have a TV that appears to not provide proper EDID info to the HDMI or DVI ports of my Intel DH77DF motherboard. I received some pointers from this list that pointed me in the direction of creating my own EDID file and I now have a binary blob that matches what the service manual says is the 
proper EDID info.
But I am unable to get the drm_kms_helper module to load and use this file. 
My relevant kernel config options are.

CONFIG_DRM_KMS_HELPER=m
CONFIG_DRM_LOAD_EDID_FIRMWARE=y

my relevant kernel command line contains:

video=card0-HDMI-A-1:e
drm_kms_helper.edid_firmware=card0-HDMI-A-1:edid/lg42lb9df_hdmi1.edid


The variant without card0- should be the right one.



OK. Changed it. What if I had more than one video card?
Two connectors from two distinct card should not get the same suffix number even if they use same technology, so it should work. (unless something was 
changed recently)


The edid file:
# ls -al /lib/firmware/edid/lg42lb9df_hdmi1.edid
-rw-r--r-- 1 root root 256 Oct 16 05:46 /lib/firmware/edid/lg42lb9df_hdmi1.edid 

connector info from /sys/class/drm/
card0 card0-DP-1 card0-DP-2 card0-DP-3 card0-HDMI-A-1 card0-HDMI-A-2 
card0-HDMI-A-3  card0-VGA-1  controlD64  version



Which should I use? HDMI-A-1, HDMI-A-2, or  HDMI-A-3? Why re there 3??
And I don't really understand why I have 3 entries for the one hdmi port? Nor do I really understand _exactly_ how to define the connector in my kernel command line or which of the 3 connectors from /sys I should be 
using. I've tried different variants. Ie. card0-HDMI-A-1and HDMI-A-1.

The results in the kernel log file remain:

[    1.879654] drm_kms_helper: Unknown parameter `edid'


As your drm_kms_helper is built modular, did you try not putting that
parameter on kernel cmdline but rather put it in modprobe's configuration 
for that module? (may doing the whole loading manually).



I've created a /etc/modprobe.d/20-drm_kms_helper.conf with:
options drm_kms_helper edid_firmware=HDMI-A-1:edid/lg42lb9df_hdmi1.edid
and now I'm getting something different. It looks like it's trying. In fact I actually get a screen on the TV now. It's not 1920x1080 but 1024x768 at 
60hz.


As things get slightly better now, check what kernel detected:
- /sys/module/drm_kms_helper/parameters/edid_firmware
   (should contain the path to firmware file)
Make sure both the firmware and modprobe config get included in your initrd 
if you're using one.

Interesting, kernel/udev can't find the edid file but know what file
to look for... Is the edid file available at that time (initrd?)?


I get a couple of the above messages.

That's as ago with getting edid from hardware.
# modprobe drm_kms_helper edid_firmware=HDMI-A-1:edid/lg42lb9df_hdmi1.edid 



I can't seem to rm the modules already loaded to try this.


There are multiple steps needed to be able to rmmod those modules:
- stop DRM users (e.g. X)
- disable fbcon
   echo 1 > /sys/class/vtcon0/bind
   echo 0 > /sys/class/vtcon1/bind
   (assuming vtcon1 is fbcon, vtcon0 is VGA console)
- rmmod i915
- rmmod drm_kms_helper
Note that at time of modprobing i915 connectors will have different names! 
(probably HDMI-A-4, HDMI-A-5, HDMI-A-6)
Alternatively you could blacklist all drm modules so they don't get loaded automatically and you can load them manually one at a time when system has 
booted.
It turns out the boot params "video=HDMI-A-1:e video=HDMI-A-2:e video=HDMI-A-3:e" are what actually turned the tv "on". They seem to default to "d". In any case I now have only that in my grub file except for the "video=1024x768" and I'm not really sure what that actually does. 

My /etc/modprobe.d/20-drm_kms_helper.conf contains:
options drm_kms_helper edid_firmware=HDMI-A-1:edid/lg42lb9df_hdmi1.edid

How can I add the other connector info to that file BTW?

It now looks like it is finding the edid file.
 # cat /sys/module/drm_kms_helper/parameters/edid_firmware
HDMI-A-1:edid/lg42lb9df_hdmi1.edid
What I End up with is a 1024x768 on both the DVI and HDMI port outputs and then every 5-10 seconds the below gets spewed to the log file and the system is unresponsive while this occures. I don't understand why this messes up the DVI port. With no 20-drm_kms_helper.conf file the DVI port get 1600x1200

Should I maybe add the info for the other connectrs to the modprobe file? If so what would be the syntax? 

dmesg attached
One thing I forgot to mention is that I do have the edid file built into the kernel via: 
CONFIG_EXTRA_FIRMWARE="edid/lg42lb9df_hdmi1.edid"
