Nouveau - Sep 2022 - Patch to TroubleShooting.html

Hi Nouveau

Whoever is in charge of the web-pages, could I persuade you to make a minor
update of

https://nouveau.freedesktop.org/TroubleShooting.html

It says (among others)

One option is to provide a custom EDID. You can do this by adding
drm_kms_helper.edid_firmware=VGA-1:edid/your_edid.bin to the kernel command
line.

But drm_kms_helper.edid_firmware is deprecated. Furthermore, there is no mention
that the custom edid should be placed in /lib/firmware. And now we are at it,
one can supply more than one edid. So I would suggest to change the above to eg


One option is to provide a custom EDID. You can do this by creating the
directory /lib/firmware/edid (if it does not exist) and placing your custom edid
file(s) there. Then add
drm.edid_firmware=connector1:edid/your_edid_1.bin,connector2:edid/your_edid_2.bin,...
to the kernel command line. That will make the system use your_edid_1 for
whatever is attached to connector1 and so on. As an example,
drm.edid_firmware=DP-1:edid/foo.bin will use /lib/firmware/edid/foo.bin for
whatever is attached to DisplayPort 1.


Cheers,

Klaus

Hi Klaus,

The edit buttons on the wiki link to the source repository on GitLab. I 
asked about developer access on 2022-08-05 and never received a reply:

https://lists.freedesktop.org/archives/nouveau/2022-August/040616.html

I haven't tried asking on IRC (#nouveau on OFTC).

(It looks like the <https://nouveau.freedesktop.org/InstallNouveau.html> 
page needs some updates too.)

Good luck,
Owen

OK. Thanks for the warning. I will see if I have the energy to continue.

Cheers,
Klaus
