Does it work fine on a cold boot, but only fails on a warm boot? (Is that what
you mean by "after rebooting"?)

Ok, md5sums are correct, so your firmware is not corrupted.

I will try to reproduce on the same setup as you (GTX970/4.6-rc4) - can you
confirm that you are using pure 4.6-rc4 without any extra patch? Also, can you
run

$ cat /proc/config.gz >config.gz

and attach the created config.gz file?

Thanks!

Yes, its a clean 4.6-rc4, from kernel.org.

I Post the .config in 10h.

Successfully booted with your config on 4.6-rc4 and a GM206 (GTX 960). I am
trying to get my hands on a GTX970 to see if this is specific to the card.

Are you able/willing to compile custom Nouveau modules in order to get more
debug information?

This line in the log looks kinda suspicious to me:

[    2.278551] nouveau 0000:01:00.0: enabling device (0000 -> 0003)

I am not seeing it on my end ; could this mean that the Geforce card is a
secondary display device, and that the integrated Intel graphics is the main
one?

In this case maybe you need this patch, which is not in -rc4:
https://lists.freedesktop.org/archives/nouveau/2016-April/024523.html

Also I am surprised by the report that the screen goes blank after this -
failure to initialize GR should not interfere with the ability to display a
framebuffer (only acceleration will be disabled).

Let's make another experiment: can you move /lib/firmware/nvidia/gm204
somewhere else, reboot (you will see a complain about missing firmware files in
the boot log), and tell us whether the display is active after that?

Thanks!

Yes, iam booting with intel-gpu and nvidia-gtx970 card activated. There is a
picture on the intel screen. If i disable the intel gpu in the bios, there is
no output on the nvidia screen.

I try to ssh to the machine, with disabled intel-gpu.

I have a modiefied Bios in the GTX970. Could this be the answer? I disabled the
Fan on the gtx970 under 50C. But everything works on Windows10 and kernel 4.5.0
with nouvau driver.

Hi,

Your latest comments seem to indicate that the issue is not related to firmware
- it just happens to manifest itself at this stage as well when firmware is
loaded.

2 things to try:

1) Can you try loading Nouveau with the "config=NvForcePost=1" option?
Adding
"nouveau.config=NvForcePost=1" to your kernel command line should do
it.

2) Can I get a full log of you booting with the /lib/firmware directory
removed, or can you confirm that when you can see Nouveau complaining about the
firmware when you boot in this configuration?

Thanks!

Hi,

Not sure why you enabled MSI - I asked if you could set NvForcePost, not NvMSI?
Or maybe you posted on the wrong bug?

My gut feeling is more and more that for some reason devinit is not ran by the
bios and the heuristic in 4.6 does not detect this (which is why I wanted to
try NvForcePost). If you are compiling your own kernel, could you try applying
the following patch and see if things are improving?

Added Patch and NvForcePost=1 

Result is the Same. I did not enable MSI by bootparamter, it looks like its
enabled by default...

Hi,

Ok, so it seems I'm affected too: my desktop with GTX970 doesn't boot
kernel
4.6 (comes with recent openSUSE Tumbleweed snapshot release). Although it does
boot 4.5.4 kernel, from which I'm writing this comment.

I've found this issue by googling "timeout at
drivers/gpu/drm/nouveau/nvkm/subdev/secboot/base.c:145" message from my
logs.

Relevant log parts are pretty much identical for me, I can post them here, if
needed. 

Firmware checksums are identical. Haven't tried NvForcePost=1 and
pci_msi=off
yet, will try later if needed.

Anyway, +1 here.

Motherboard: Gigabyte GA-MA770
Videocard: GTX 970 by MSI
UEFI and SecureBoot are enabled.

Booted the last kernel from tumbleweed with debug on (4.6.2-1).

Firmware MD5's are the same as mentioned.

DMESG output posted above, as mentioned I left the beginning intact, but cutted
rest off due to file being very large (65 MB, it never stops spamming the fifo
message).

If you'll need more info / something specific, just mention it, will follow
the
bug.

https://lists.freedesktop.org/archives/nouveau/2016-June/025336.html

I've appended the dmesg, the kernel source was linux-next as of 2016-06-24
with
the patches mentioned applied.

Same symptoms, running either `kernel-4.6.3-300.fc24.x86_64` or
`kernel-4.6.4-301.fc24.x86_64` on Fedora 24.

Do you need some more information from me?

Asus Z77 and GTX970, it seems the first fifo caused by

changing the value to 0x0 allowed the machine to boot, still with lots of

Looks like we are narrowing it down. This may be a bug in the firmware itself
when dealing with high addresses. Let me check on my side which address the ACR
is loaded, and if I can force a lower address for it.

Tried on a 4GB GM206 / 4.6.4, it passed without any issue:

... and then I could run glmark2 without any error.

Tried messing with the WPR address to make it invalid and see if I could get
the same error. It happens to be different:

So not sure where this REGION_VIOLATION comes from. Guess I will need to ping

Another interesting experiment would be for someone hitting this to:

- Boot with "nouveau.modeset=0 3" on the kernel commandline.
- Suspend the machine with "echo mem > /sys/power/state"
- Resume the machine (there will be no display at this point, so you'll need
ssh access or to type the rest blindly)
- Execute "modprobe nouveau modeset=1" and see if the situation is any
better.

Before suspending, also run "modprobe -r nouveau" ;)  (Thanks Ilia!)

Btw. I try to boot Arch Live CD, kernel 4.6.4 with option
"nouveau.modeset=0"
and it works.

For the record, I had dealt with this problem too, boots fine on 4.5.* but not
4.6 (as of today). I have also tried a GTX 960 and a GTX 980 (4GB) (now my
current). Fedora 24 boots fine with each of those cards on 4.6. The EVGA GTX
970 (4GB) did not boot (at all) on kernel 4.6. However it will boot under 4.5
but the monitor(s) connected to the 970 card will not work. (I run two cards).

Add it in /boot/grub2/grub.cfg to the kernel commandline for the kernel you
want to boot, or change the boot config inside grub2 for a oneshot (F12). But
you should have just googled that ;-)

Right, `nouveau.modeset=0` wont’t prevent Nouveau from loading, however the
driver is in a "disable" state and won’t do a thing:
> modeset
> Whether the driver should be enabled. 0 for disabled, 1 for enabled, 2 for
headless

Hi QA:

 I had can to create the manual blacklist entry for nouveau.   I did this
because I wanted to use the non-free driver.  This is also required if you
want to use the Intel HD internal graphics card with a Nvidia chip set as a
secondary card.

The first edit will disable nouveau and verify by "lsmod | grep -i
nouveau"



Manual edits required to get this working.

1. Created blacklist entry, /etc/modprobe.d/blacklist­nouveau.conf as shown
below

# cat /etc/modprobe.d/blacklist­nouveau.conf

blacklist nouveau

options nouveau modeset=0

2. kernel option used, nomodeset

Below (lines below) if you want to use the Nvidia non-free driver support:

3. Used Nvidia xconfig tool, nvidia­xconfig

4. Edit the file manually to see what drivers were being used , it should
state: Drivers “nvidia”

5. ** Special note, I have two separate video GPU cards and decided to use
individual heads, device1, device2


Now after booting, Nvidia drivers are working because the X server came up.
I noticed that

'num­lock' was off. Verification of X is as follows:

1. Verify what is in proc, lsmod, dmesg messages

# cat /proc/driver/nvidia/version

NVRM version: NVIDIA UNIX x86_64 Kernel Module 352.30 Tue Jul 21 18:53:45
PDT 2015

GCC version: gcc version 4.8.3 20140106 (OpenMandriva Association) (Linaro
GCC 4.8­2014.01)

This is the driver we wanted, 352.30, installed from 'mcc'; manual edits
required for the blacklist

file creation. The installation needs to create something. The Nvidia
installer does create a file for

you using their manual installation method by executing the driver
installation <Nvidia-
driver.version>.run.

2. Verify X log in /var/log/Xorg.0.log.

3. Run Nvidia settings and Nvidia System Management Interface tool,
nvidia­settings, a X tool,

and nvidia­smi, System Management interface tool

Nvidia­smi, reports the driver version match such as in
proc/driver/nvidia/version and reports the

GPU(s). GPU­0, is the 960; GPU­1, is the 730 card. I want to run the 960 as
the primary (a

physical connection to a 24in monitor).

PS, I have used this in the past.  You can also try using
"acpi_osi=Linux"
on the kernel command line.
This allows be to boot with the Nvidia card as a primary video source with
the Intel HD graphics card disabled in BIOS.

I have found that the BIOS is disabled and initfs still loads the i915
driver module

PS, I have used this in the past.  You can also try using
"acpi_osi=Linux"
on the kernel command line.
This allows be to boot with the Nvidia card as a primary video source with
the Intel HD graphics card disabled in BIOS.

I have found that the BIOS is disabled and initfs still loads the i915
driver module

patch, possible fix

After some messing around i am able to boot.

I noticed it crashes only when initializing certain nvkm_gpuobj, which has it
'nvkm_gpuobj->size' bigger then
'nv50_instobj(memory)->mem->size <<
NVKM_RAM_MM_SHIFT'.

catching that specific case made it better.

from your kernel directory do 'git apply
0001-nvkm_gpuobj-size-is-smaller-then-nvkm_gpuobj-size-ca.patch

and if you can post the boot log.

So, I just install fresh Fedora 24 with kernel-4.5.5, then remove nouveau from
system completely:

1. # echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf

2. Paste ‘rd.driver.blacklist=nouveau’ to end of ‘GRUB_CMDLINE_LINUX=”…”  in
/etc/sysconfig/grub

3. # grub2-mkconfig -o /boot/grub2/grub.cfg

4. # dnf remove xorg-x11-drv-nouveau

5. # dracut /boot/initramfs-$(uname -r).img $(uname -r)

After this steps reboot, upgrade system to kernel-4.6.5, and install nVidia
proprietary driver. Everything works just fine.

Hi Ilia,

I applied your patch and my system now boots up. I saw an login-screen-image
from before the boot for a split-second.  apart from that, it seems to run
fine. (no stress testing done, just firefox and some gnome terminals...)


what does your patch do? increase the reported size of some of the objects?

--- Comment #59 from Ilia Guterman <amfernusus at gmail.com> ---
It increases the size of nv50_instobj objects that report the size of 0x3000.

Struct "nv50_instobj" has size of 0x3000 but it's parent structure
"nvkm_gpuobj" reports different size, a size of 0x97000.

All the other instances of nvkm_gpuobj and their child nv50_instobj report
similar size size to each other so they are fine.

It is a mystery to me why the sizes doesn't match, because if I understand
correctly the sizes are reported by the GPU itself.

I do not use the non-free Nvidia driver because it causes many more problems
than it solves: every kernel upgrade might break things until a new driver is
released. At least with the nouveau, it's more in sync.  Well, this bug none
withstanding :)

I have to install the Nvidia driver on on development systems because I am
doing some programming with CUDA.  I use the CUDA Toolkit in C/C++.  I am
converting some of the software over to OpenACC.  OpenACC has it own
compilers but CUDA requires the non-free driver because the tools
communication to the driver with the APIs.

In reference, I do use the nouveau driver on non-CUDA development systems.
I like how the development teams respond to bugs and fixes.  There are some
differences in the behavior of the kernels between 4.6.x and 4.7.x with the
video drivers.  I am not sure if is related to libdrm, mesa, of libGL
types.  I have a 960 GTX which is in the same product family as the 970
GTX.  Had problems with the 4.7.0 kernel and reverted back to the 4.6.5
kernel and working with some limitations.

I don't see a way to lock this bug down, unfortunately, but Efram, please
refrain from further comments other than to say "Yes, I have tested the
provided patch and it works" (or doesn't work), once such a patch has
been made
available. [It has not yet.] This is not a discussion forum.

There are a few hackpatches available that "work around" this, but
they aren't
real solutions. Wait for something from Ben before reporting test results.

Thanks for everyone's patience!

Thanks for the comment. Will do.  I uninstalled the non-free driver and
reverted back.  I will report the nouveau version, firmware, and kernel
being used.  I know the kernel is 4.6.5 64bit.

@Ben: definitely neither rushing nor pestering you but is there an ETA for
this?  

Is there anything I can do to help there?

Is there a chance that this bug will be fixed before Fedora 25 comes out
(https://fedoraproject.org/wiki/Releases/25/Schedule)? It would be really
irritating to not be able to upgrade because of it.

Is there anything that we can do to help make this faster?

I would offer a patch but my X11 driver skills are weak. However, I am happy to
test a patch if needed.

well, we have an idea how we can fix the issue, but chances are it might break
other cards as well. Anyway, the fix won't be too difficult and a backport
should be fairly simple.

By the way, this affects the kernel module only.

This still stops my machine from booting or X11 from running if I disable the
Nouveau driver. Or am I being dense and missing something?… ☺

most likely, yes. You should check dmesg in this case and check what is
happening.

Err… If I disable Nouveau, I get no X11 at all. If I leave it enabled, the
machine does not boot.

Is there a way to boot with a kernel 4.6X and have X11 work via Nouveau?

Was just curious about this issue myself, on Mint 18 w/ kernel 4.5.4 and my GTX
980 just gives me a black screen as well. Worked on Fedora with later kernel
versions however so I take it its not strictly a nouveau issue but its beyond
my capabilities to even find the problem?

Could we at least have this as a patch for now until a better one comes along.
Otherwise us poor folks owning GT970 cannot update to Fedora 25… ☹

we can't. there would be a less generic patch needed, because it would
affect a
lot of different GPUs as well and mess with the amount of VRAM reported.

Hi. I've noticed that the liquorix kernel [ https://liquorix.net ] works
with
my GTX970. It worked with version 4.6, 4.7, and now 4.8. I don't know what
it
does differently to make it work, but maybe a solution to the problem can be
found there.

does your GTX 970 have 4GB or 2GB? The 2GB version should work.
Otherwise, maybe the firmware files are missing so that not all GPU features
are available. Anyway, check with glxinfo if nouveau is actually used

Hi Ben,

Patch did not do the trick for me (log attached). Confirmed that
0001-nvkm_gpuobj-size-is-smaller-then-nvkm_gpuobj-size-ca.patch still
succeeded, so apparently the method is not perfectly correct. Rather strangely
the printk'd value of 0x100ce0 is 0x00000000...

Yeah, everyone, don't bother trying this.  This register is written by the
secure boot ucode, so the problem remains unsolved.

Hi all:

Please help me understand the ram issue on the video card, is too many
buffers created?  I did not have this problem on a 4.6 kernel, now the
kernel has been upgraded twice, 4.8.5, and now 4.8.6.  No problems using a
960 GTX w/4GB DDR5 memory, plus I have a secondary 730 GTw/1GB RAM.

Please advice

The issue is that the 4GB are laid out "funny" on a GTX 970 (but not
other
models), and nouveau doesn't properly handle that.

You had this problem on a 4.6 kernel, as it was the first to provide the
secboot firmware loading functionality (assuming you had the firmware in
place). To get back to the previous behavior, remove the firmware, or boot with
nouveau.noaccel=1 nouveau.nofbaccel=1 which should avoid initializing the
graphics accel engine. (And hopefully avoid secboot as well, but I'm not
100%
sure.)

Also, before I go insane, *please* stop replying to these via email. Use
bugzilla directly. Your (Efrem's) email client insists on creating html
attachments which are entered into bugzilla. And you also reply-to-all, so I
get the thing 2x, once via bugzilla, once directly.

Just to be crystal clear: setting the two settings above will boot with X11 (so
I can get a gdm login screen and an Xsession…) but just without any 3D
acceleration?

Would this work around work on Fedora 25?

--- Comment #101 from Bernie Innocenti <bernie at codewiz.org> ---
I tested 0001-nvkm_gpuobj-size-is-smaller-then-nvkm_gpuobj-size-ca.patch with
4.9.0-rc7 and it correctly initializes the console at 3840x2160 @ 30Hz (for
some reason, the 60Hz mode is not detected).

I also tried the patch on top of drm-next (which as of today is still based on
4.9.0-rc5), but all I got a blank screen. This branch has other stability
issues, so it's not necessarily a nouveau regression.

With 4.9.0-rc7, I can start Xorg, but xf86-video-nouveau fails to initialize:

 [   336.771] (II) [drm] nouveau interface version: 1.3.1
 [   336.771] (EE) Unknown chipset: NV124

This is expected, since GM20x acceleration landed after
xf86-video-nouveau-1.0.13. I'll try rebuilding from head and report back.

Hi,

I'm joining the group of gtx970 4GB owners who have issues with nouveau :)

I've applied 0001-nvkm_gpuobj-size-is-smaller-then-nvkm_gpuobj-size-ca.patch
and now I have at least a console.
However, no x11 with acceleration.

I've check the kernel messages, and besides the tons of traces
("disp:") I see
this line:
: #### nvkm_gpuobj_heap_acquire gpuobj->addr 4286832640, gpuobj->size 4096
: #### nv50_instobj_size 32768
: nouveau 0000:03:00.0: priv: GPC0: 419df4 00000000 (1840820e)
: nouveau 0000:03:00.0: priv: GPC1: 419df4 c0000000 (1a40820d)
: nouveau 0000:03:00.0: priv: GPC2: 514884 c0000000 (1c40820e)
: nouveau 0000:03:00.0: priv: GPC3: 51d084 c0000000 (1f40820e)
: nouveau 0000:03:00.0: gr: init failed, -28


Seems like secboot failed somewhere. Looking at the code, GR failed most likely
when secboot tried to initiate the reset command.

Forgot to say that I'm using kernel 4.9.

If you need me to do some tests, let me know

don't use that hack.

use the "limit ram to 3 bars" one instead.

Unfortunately I already tried that patch alone, and I was unable to have a
console, only black screen.

And I do not have a serial for the traces, so I didn't investigate
furthermore.

Hey, as well even though this is fixed in the development branch I was asked by
one of the other nouveau guys to post this for people running older kernels
since it's easier to backport. This is a very dirty hack that disables the
last
512 MB of VRAM for the GTX970, however it does technically fix the issue and
let your GPU run. If you can't use Ben Skegg's patch, give this one a
try

I tested the nouveau module built from https://github.com/skeggsb/nouveau on
top of the latest drm-next kernel and I can confirm that it fixes the black
screen issue on my GTX 970 with 4GB of VRAM.

Ben, would it be possible to extract the relevant patches and backport them
onto recent stable kernels such as 4.9 and 4.10?

Haven't tested Lyude's patch yet.

Hi,

Just to let you know that I'v just tested the patch (remove last 512MB)
Indeed, the kernel can boot (4.10.1 with latest fw) but I'm loosing the
screen
while the kernel tries to switch to nouveau.
A hotplug brings back the console (with corrupted top lines)
My setup: 1 DVI screen at 1600x1200 (main), 1 DP 4K screen (black) and 1 HDMI
TV (black too)

If I have some time, I will try to remove all the displays and check for
errors.

One day it will work :) But having an open source driver is really challenging
these days :(

Have you tried building Ben’s tree (see comment #112) and it didn’t work for
you? Because the issue should be fixed in the development version of Nouveau,
and by the looks of it, will land in Linux 4.12.

nouveau-fdo94990-linux-4.10.patch

I was able to get my GTX 970 working with KMS on Linux 4.10 by cherry-picking a
few of Ben's commits from the master branch onto the linux-4.10 branch (see
patch).

These are also available in the linux-4.10 branch of
https://github.com/hpjansson/nouveau.git for convenience.

With this, I can boot and Plymouth and Xorg work fine, but Wayland still
freezes -- however, I think that's caused by a different issue.

Sorry for the delay, my BIOS got re-written by Windows (thanks⸮) and it took me
some time to fix it. 

I am happy to wait till 4.12 is released on Fedora but would like to know it
works: several comments pointed to it being flaky…

Hans Petter had X working (though not Wayland) by cherry-picking those commits
and Bernie had it working as well with Ben's tree.
The others tested different patches.

As an owner of a MSI GTX970 4G, I can confirm that with 4.12-rc1, I can boot
perfectly fine with a single monitor connected, and with Mesa 17.1.0 on the
userspace side, my user experience with KDE Plasma is thus far
indistinguishable from the NVIDIA blob. Awesome work there, kudos.

Plasma's Wayland session does freeze shortly after login, but that's not
supposed to be mature and can be caused by any amount of things.

Now, if I try to add a second monitor, I get corrupted output after modeset
seemingly, but I'm pretty sure that's bug 89664.

--- Comment #127 from fariouche at yahoo.fr ---
Hi,

I finally tried the 4.12.2 kernel, and in my case it does not fully work :(

I can see a working console, but:
- only on my first monitor (DVI)
- no x11 (I can see a brief display of xfce4 but immediately turns black and no
more display, even if I return to the console.)

I think I'm facing 2 different issues. One is about detecting my second
monitor
(a 4K LG 31MU97 plugged on DP-0 (this display is maybe a bit slow to probe))
The log shows a lot of error concerning this monitor...

But I do not see anything on my third output too (HDMI, this is an av receiver,
with a full HD tv). No error at all for this one, even the resolution is probed
correctly by xorg.


The kernel log shows an EDID error for the LG monitor...

I can attach all the relevant logs.

Any idea? Maybe this belongs to an other bug?
