Trying to setup "Smart" TV edid file [SOLVED]

graysky · 2023-09-01 13:04:48

I have an Arch box running kodi-gbm via a systemd service. The connected "smart" TV requires being turned on when booting the Arch box, or else is fails to properly detect the 4k mode Kodi is using.

I am trying to circumvent this by defining a custom edid via kernel parameter.

I did this:

# cp /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card1/card1-HDMI-A-1/edid /usr/lib/firmware/tv.dat

It looks valid:

# parse-edid </usr/lib/firmware/tv.bin 
Checksum Correct

I added this line to grub.cfg:

GRUB_CMDLINE_LINUX_DEFAULT="audit=0 loglevel=3 quiet drm.edid_firmware=tv.dat"

But I am finding errors in the log.

# dmesg|grep tv.dat

And booting into the system with the TV off however did not allow for the detection of 4k. Kodi started in 640x480 @ 60 Hz. What am I doing wrong?

There's a discrepancy between tv.dat and tv.bin in your post and -2 is ENOENT
If you've amdgpu in the initramfs, you also want to add the EDID there, https://wiki.archlinux.org/title/Kernel … s_and_EDID

You are correct, my mistake:
1. I corrected all references to tv.bin
2. I added it to the FILES array in mkinitcpio.conf

Now I can successfully boot with the TV off and have the Kodi GUI be in the right mode! Thanks!
