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...

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.

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.

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…

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.

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.

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 :(

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.

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

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.

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 :03:00.0: priv: GPC0: 419df4  (1840820e)
: nouveau :03:00.0: priv: GPC1: 419df4 c000 (1a40820d)
: nouveau :03:00.0: priv: GPC2: 514884 c000 (1c40820e)
: nouveau :03:00.0: priv: GPC3: 51d084 c000 (1f40820e)
: nouveau :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

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.

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?

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

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.)

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

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

we can't. there would be a less generic patch needed, because it would affect a

limit ram to 3 bars

Zach Wolfe: one method is to limit the ram usage, but its a bandage not a fix.

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?

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?

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

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?… ☺

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.

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.

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

Is there anything I can do to help there?

[Efrem Mc]

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.

--- Comment #67 from Ilia Mirkin  ---
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!
