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:

Depending upon your bootloader, those files will need to be put on your initramfs or whatever the Android bootloader looks for.

denysvitali commented 7 years ago

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

denysvitali commented 7 years ago

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

Echelon9 commented 7 years ago

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.

Echelon9 commented 7 years ago

@denysvitali any update from your further testing?

denysvitali commented 7 years ago

I'm trying to port the 4.14-rc1 kernel right now, afterwards I'll try with your suggestions. I'll report back soon! 👍

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

denysvitali commented 7 years ago

May be helpful later: https://www.phoronix.com/scan.php?page=news_item&px=Tegra-2-Video-Decode-Driver-V3

Echelon9 commented 7 years ago

Probably not, that relates to the older Tegra 2 GPUs. This device has a Maxwell series GPU.

denysvitali commented 7 years ago

Yeah, realized after I posted. Brainfart :P

mirh commented 7 years ago

Ideas

denysvitali commented 7 years ago

Maybe @Gnurou can help us, somehow

Gnurou commented 7 years ago

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.

denysvitali commented 7 years ago

@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

Gnurou commented 7 years ago

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.

opendata26 commented 7 years ago

You could try adding drm.debug=31 to cmdline for more debugging

opendata26 commented 7 years ago

@denysvitali also try building as a module

Gnurou commented 7 years ago

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.

denysvitali commented 7 years ago

It works indeed. I've selected nouveau as a module, added drm.debug=31 (to add more debugging) insmoded the moduleit and tadà: Accleration is now available

It is still laggy with GNOME and videos are choppy, but it seems to be accelerated 👍

Thank you!

Gnurou commented 7 years ago

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.

denysvitali commented 7 years ago

@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

Cause those patches haven't been pulled/mainlined yet.

Gnurou commented 7 years ago

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.

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:

See the gist

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 😞

Gnurou commented 7 years ago

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.

opendata26 commented 7 years ago

You could try disabling aglx?

denysvitali commented 7 years ago

As suggested by @mirh (in private) this may be useful

Gnurou commented 7 years ago

Probably not, as this appears to be for managing the non-upstream (i.e. not Nouveau) driver.

vartom commented 6 years ago

Hey. I downloaded the kernel and root directory of the message https://github.com/denysvitali/linux-on-pixel-c/issues/2#issuecomment-340314777. The system does not start. Tried to rebuild the kernel, as well as no launch. I found how to solve the problem with the firmware files. The solution is to add the firmware files to the vendor's directory in initramfs or add all the files to the kernel. Unfortunately, it still did not let me run the system. Maybe to me another tablet revision or not a suitable bootloader. My revision 1.3, bootloader-dragon-google_smaug.7900.50.0.

vartom commented 6 years ago

Did you try to connect the monitor through HDMI?

denysvitali commented 6 years ago

@vartom Unfortunately I don't have much free time to dedicate to the project 😞 . I haven't yet found a way to have an output on the HDMI.

About the rootfs, you can try to use the kernel posted here and use the /system instructions to build your own rootfs.

No idea why drmMaster fails, but it's fatal for Xorg. It seems that glamor initialisation was OK, wondering if DRI3 is active (for node rendering) and if that could be the issue.

Any idea ?

Edit by @DenysVitali: Formatting

Samt43 commented 6 years ago

It seems that you have issues with your libglx that is at the wrong format. Another thing @gnurou can confirm, but I don't think we have to use Nouveau DDX driver but modesetting instead using glamor to accelerate X commands.

vartom commented 6 years ago

@Samt43 For kernel tests, I use the assembly of the rootfs from denysvitali https://github.com/denysvitali/linux-on-pixel-c direct link https://ded1.denv.it/pixel-c/arch-xfce-lightdm.tar.gz it works quite smoothly. Your earlier image of rootfs also works, but graphics drawing is much slower.

Samt43 commented 6 years ago

Great, can you run glxinfo ? If that works, it would mean that with a 4.15 kernel, everything is there to enable graphical acceleration for tegra without any mesa patch ! :)

Samt43 commented 6 years ago

Hi @Vartom, I compiled you kernel 4.15, and i could run X correctly. I used the lastest rootfs available by build system. Unfortunatly, llvmpipe was used for 3d rendering and UI was a bit slow. Could you run glxinfo to know if your config is using GPU correctly ? It seems according to the log that you were really using nouveau DRI driver :)

Thanks a lot in adavance,

Samt43

vartom commented 6 years ago

In the system that I try there is no glxinfo. In which particular version of the system do you have a problem with 3D? I have now tried this https://github.com/denysvitali/tegra-nouveau-rootfs/releases/tag/untagged-439d9f4a817e73403582. It seems to be running asked for a password, but then does not boot.

Samt43 commented 6 years ago

Seems like you have to install gnome-shell or xfce4 in order to have something after boot. (i had the same issue) I could do some test and i have the same logs as yours. We only have software rendering for now, it seems that it's due to this : AIGLX: Screen 0 is not DRI2 capable

I could have acceleration working with a mesa patched some days ago but only for wayland, I continue to look on this,

But this is not stable (. kmscube works through time and sometimes takes off with errors. weston-launch does not start. startx giving out 3 rectangles All this was received on the assembled rootfs with the settings approximated to the original ones.

Samt43 commented 6 years ago

@friesoft No I was talking about this patch https://github.com/Samt43/mesa/commit/d64c261dc62c2b5a78163579ddcf349f7ddc2ed3 From the renderonly branch of @Gnurou plus the patch I made to Port it on Pixel c : https://github.com/Samt43/mesa/commits/renderonly With this compiled and installed using the rootfs scripts, I could run Weston correctly with acceleration. The patches that you are talking about are very recent and seem to be equivalent to @Gnurou patch but uses more recent features of the kernel. This is a great hope for us, and according to the description it should work for Pixel C. I will try to compile a 4.16 kernel soon and try to compile Mesa with these patches when I will get some time ! Thanks a lot for the infos !

Edit : it seems @vartom already tried to compile mesa from this and that resulted in an instable UI. @vartom don't we need a 4.16 kernel for this ?

denysvitali commented 6 years ago

@Samt43 The 4.16 kernel doesn't seem to work. Apparently they've messed up with some arm instructions. We'll have to wait for a new tagged release (that will be released today)

vartom commented 6 years ago

@Samt43 @denysvitali It is possible that for this (mesa) you need the kernel 4.17 https://github.com/thierryreding/linux/tree/for-4.17/work In patches, the general line of updates is viewed "Support sync FDs ..."

denysvitali commented 6 years ago

I've tried the for-4.17/work kernel, unfortunately it doesn't work. The display stays black. I'll push the kernel source (and a prebuilt image) as soon as possible.

denysvitali commented 6 years ago

@thierryreding for-4.17/work boot image is available here (source on my repo) whilst the latest 4.16-rc3 kernel boot image is available here

Please note that both images use my initramfs, which requires the rootfs in /system (/dev/block/mmcblk0p4).
You can still unpack / repack it to boot the kernel image with another initramfs.
