[gentoo-user] nouveau: gr: failed to load firmware "gr/sw_nonctx"

[thelma]

I have "nouveau" build into kernel  but it doesn't work:

Fom dmesg:

nouveau 0000:08:00.0: NVIDIA GP107 (137000a1)
nouveau 0000:08:00.0: gr: failed to load firmware "gr/sw_nonctx"

I have "linux-firmware" installed but there is a "?" mark beside it

It means the version you have installed is no longer in the tree. You
should update to the latest.

I've never used NVIDIA cards with Gentoo, but in firmware terms you need to 
specify in your kernel what firmware you want installed in it.  Have a look at 
this guide:

 https://wiki.gentoo.org/wiki/Nouveau/en

and this:

 https://wiki.gentoo.org/wiki/Linux_firmware

You'll need to add the firmware the video card asks for here:

Device Drivers  --->
  Generic Driver Options  --->
    Firmware loader --->
       -*- Firmware loading facility
       () Build named firmware blobs into the kernel binary  <==

In this instance your card NVIDIA GP107 should need '/lib/firmware/nvidia/
gp107', so the respective entry for it in the kernel config ought to be:

CONFIG_EXTRA_FIRMWARE="nvidia/gp107"

Someone more clued up on these cards can correct me or add to it.

Thank you, but I've managed to install "nvidia" following:
https://wiki.gentoo.org/wiki/NVIDIA/nvidia-drivers

What confused me is the output from two kernels:

linux-5.4.80-gentoo-r1
was installed with: genkernel --menuconfig all
and "nouveau" was working OK on that kernel:

grep CONFIG_EXTRA_FIRMWARE ../linux-5.4.80-gentoo-r1/.config  showing:
CONFIG_EXTRA_FIRMWARE=""

The one below was compiled manually:
grep CONFIG_EXTRA_FIRMWARE ../linux-5.4.72-gentoo/.config
CONFIG_EXTRA_FIRMWARE=""

Both had same output, so why one kernel was working the other didn't?

Something is wrong, I just --sync and reinstall linux-firmware but the output is still the same:

This shows that you have 20201022-r3 installed but eix says the latest
available is 20201022-r2 so you have a version it thinks is not in the
tree.

Did you run eix-update after syncing?

Were both of these kernels installed with a corresponding correctly 
functioning initramfs, which had all the requisite files (including --
firmware) to boot with, or only one of them did?

Without an initramfs you will need to specify and build any requisite firmware 
blobs in the kernel image itself, so they are available to the system as it 
boots up.

Just sync'ed and on the mirror I used there is no 20201022-r2 version:

Exactly, but eix was saying there was, and no -r3, probably because you
hadn't run eix-update.

See, it's all fine now.

Heh! This package was always alright for me.  It was Thelma the OP I was

 Since I was able to make "nvidia" work I abandon fighting with
installing/enabling "nouveau"
Originally I wanted to have it as a backup switching between these two
(just in case) but it is not an easy project.
