Nouveau - Jun 2020 - NVIDIA GP107 (137000a1) - acr: failed to load firmware

Hi

With Kernel 5.7 I am still getting this, while booting:

~> uname -a
Linux zenogentoo 5.7.0 #80 SMP Thu Jun 4 16:10:03 CEST 2020 x86_64
Intel(R) Core(TM) i7 CPU 960 @ 3.20GHz GenuineIntel GNU/Linux
~> dmesg |grep nouveau
[    0.762872] nouveau 0000:05:00.0: NVIDIA GP107 (137000a1)

[    0.875980] nouveau: probe of 0000:05:00.0 failed with error -2

Old thread is here: https://lkml.org/lkml/2020/4/3/775

My Linxu-Firmware is: linux-firmware-20200421

This used to work fine with Kernel 5.5.

Please CC me for replies.

Starting with kernel 5.6, loading nouveau without firmware (for GPUs
where it is required, such as yours) got broken.

You are loading nouveau without firmware, so it fails.

The firmware needs to be available to the kernel at the time of nouveau loading.

Cheers,

Dear Ilia

Thank you for your reply.

How can I tell the kernel to load the firmware?

Ok, I am now trying this:

/usr/src/linux> grep FIRMWARE /usr/src/linux/.config
CONFIG_FIRMWARE_MEMMAP=y
# CONFIG_GOOGLE_FIRMWARE is not set
CONFIG_PREVENT_FIRMWARE_BUILD=y
CONFIG_EXTRA_FIRMWARE="nvidia/gp107/gr/sw_nonctx.bin"
# CONFIG_CYPRESS_FIRMWARE is not set
# CONFIG_DRM_LOAD_EDID_FIRMWARE is not set
# CONFIG_FIRMWARE_EDID is not set
# CONFIG_TEST_FIRMWARE is not set
