The nouveau graphics driver is looking for, but not finding, the GPU firmware files. That particular binary blob has been released in a redistributable form by nvidia.
See:
- (upstream) https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/nvidia/gm20b/gr
- (Arch package) https://www.archlinux.org/packages/core/any/linux-firmware/
Depending upon your bootloader, those files will need to be put on your initramfs or whatever the Android bootloader looks for.
Thank you for your comment, I'll try to integrate the blob file in the kernel, or put it in the /lib folder.
I'll report back my findings
Mmm, @Echelon9 that doesn't seem to be the problem. The file is available at /usr/lib/nvidia/gm20b/gr/gpccs_inst.bin (/lib is symlinked to /usr/lib), but apparently fails to load for some (to me unknown) reason
You'll want the full path to resolve to /lib/firmware/nvidia/gm20b/gr/gpccs_inst.bin in order for the kernel module to find it.
So in your approach, /lib/firmware symlinked to /usr/lib.
I'm trying to port the 4.14-rc1 kernel right now, afterwards I'll try with your suggestions. I'll report back soon! 👍
Here is the new 4.14-rc1 dmesg

Some users on Arch Linux Forums suggest to set this kernel flag:
nouveau.config=NvGrUseFW=1
I tried to add it, but the result is exactly the same. I also tried to add drm.atomic=1 firmware_class.path=/lib/firmware, but I get the same results: the binary doesn't get loaded
May be helpful later: https://www.phoronix.com/scan.php?page=news_item&px=Tegra-2-Video-Decode-Driver-V3
Probably not, that relates to the older Tegra 2 GPUs. This device has a Maxwell series GPU.
Mmm, everything seems to be in place, so I am not sure what happens here. I happen to own a Pixel C, so maybe I can try to reproduce and investigate. However I would like to avoid flashing it since I use it for work too. Has someone ever tried to boot off an external SD card and using just fastboot boot, instead of flashing?
I also think X may still require some extra patching to take advantage of HW acceleration, I can check that once the firmware issue is solved.
@Gnurou The cleanest way to do it is to format the system partition (doesn't contain any personal data) and put the Arch Linux Arm files there (rootfs). I'll post my system.img here in a few minutes, so you can try it out.
For the kernel, you can try with my latest build (from lightbar-fix branch). This kernel boots from /system/, therefore your /data partition isn't touched at all.
Kernel
This build assumes you have the rootfs on /system (/dev/block/mmcblk0p4, limited to 3.7GB)
lightbar-fix-fd6389ade197_20171029_232625.tar.gz
Boot w/ fastboot boot boot-lightbar-fix-fd6389ade197_20171029_232625.img.unsigned, keep in mind that flashing this without signing it won't work, therefore if you keep it unsigned you'll be able to boot it only via fastboot boot
Ramdisk
In case you want to boot from sdcard / whatever, you'll need to repack the kernel with the new ramdisk. Edit this to suit your needs , repack and you're good to go.
System
~~I will upload it here in a few minutes (refresh the page every 10 minutes if it isn't up yet)~~ There you are
Flash it w/ fastboot flash system system.img
Revert back to the original state
To return to a fully functional Pixel C, download the version you had on your Pixel C, extract the zip file, go to the extracted folder, unzip image-*..zip, fastboot flash system system.img, fastboot reboot. If that doesn't work, flash recovery (fastboot flash recovery recovery.img) too
Thanks for the instructions, although I'd rather not mess with my work device at all :) I remember booting to a SD card rootfs on my old SHIELD device, let me see if I can reproduce that result on the Pixel C too since USB seems to work. I suppose that kind of setup could be useful to other users as well.
Or maybe I can put my hands on another device just for this issue. I will come back once I have results.
It indeed looks like the firmware files are not present on the initramfs, which would explain why the firmware loading function returns -ENOENT.
Building Nouveau as a module should definitely do the trick. An alternative would be to include the firmware files directly within the kernel image using CONFIG_EXTRA_FIRMWARE, but that's definitely not clean. I see no reason to not built Nouveau as a module since nobody should need it until the root FS is mounted anway.
It works indeed. I've selected nouveau as a module, added drm.debug=31 (to add more debugging) insmoded the moduleit and tadà:
It is still laggy with GNOME and videos are choppy, but it seems to be accelerated 👍
Thank you!
Oh wow, that's fantastic! Try setting the GPU clock to a higher speed, performance should increase:
echo b >/sys/class/drm/card1/device/pstate
... or something like that. cat pstate to see which values are acceptable.
Is this X? I would be surprised if it works out-of-the-box, last time I checked it (and Mesa) required a few external patches to connect the display and render nodes together. But maybe this has been taken care of in the meantime.
@Gnurou Yes, it is X. Although GNOME runs on Wayland.
Unfortunately I don't have any pstate in /sys/class/drm/card1/device.
Apparently the GM20b doesn't support clocking via nouveau
Little hope of reclocking becoming available for GM20x and newer GPUs as firmware now needs to be signed by NVIDIA to have the necessary access.
Here is the tree output of /sys/class/drm. I still can't figure it out why there are two cards, and why the screen looks like this on boot, instead of showing the kernel messages (and is not available until I restart lightdm a couple of times or wait a few minutes). In previous versions I was able to show the screen content by writing "1" and then "0" to /sys/class/graphics/fb0/blank. Reading on the NVIDIA forums this is used when some configuration changes (/sys/class/graphics/fb0/mode) are made. But since our implementation only supports a single mode, the only thing we can do is to blank the framebuffer, which unfortunately doesn't always help.
I can't figure out why after some minutes I get the green bars (#1) either.

Little hope of reclocking becoming available for GM20x and newer GPUs as firmware now needs to be signed by NVIDIA to have the necessary access.
That's a bit outdated. Moreover, X1 seems like the luckiest nvidia gpu since half a decade. EDIT: *fixed last link
I tried the nouveau.NvFanless=true / nouveau.conifg=NvFanless=1 boot parameter, but apparently nouveau doesn't recognize it

Sorry, my mistake. The pstate node has been moved to from sysfs to debugs. So you should be able to find it under /sys/kernel/debug or wherever debugfs is mounted.
Still I am not convinced that X is using acceleration at the moment. You may want to check by looking for mentions of glamor the in X logs, or running glxgears or some other GL-enabled application. My bet is that some patching is still needed.
Found it: /sys/kernel/debug/dri/1 (which is the same as /sys/kernel/debug/dri/129)

I also saw that there is an nvidia_drv.so in the Linux 4 Tegra drivers package. I have now tried to copy the necessary files in the correct places and I get the following, then the system hangs:
It may also be due to the fact that all the NVIDIA libraries filled up my /system partition (which is only 3.8 GB), therefore I'm having some space problems too now 😞
I think that's the stage where I need to look at my old Xorg an Mesa repositories. :) Let's see if I can get the system to boot and run on a device first, will probably take a few days before I can make an attempt.
