Nouveau - Jan 2011 - [Bug 33165] New: Nouveau + nvidia GT240 = unworkable

https://bugs.freedesktop.org/show_bug.cgi?id=33165

           Summary: Nouveau + nvidia GT240 = unworkable
           Product: xorg
           Version: 7.5
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: shulenkov at gmail.com
         QAContact: xorg-team at lists.x.org


In most of the modern distros by default is loading nouveau for nvidia cards.
When it loading by default, it hangs completely, don`t response on all known
keys (example, Alt+SysRq+B). Logs was clear with 0 bytes. Problem was solved by
change card for an older nvidia 9x00 and installing proprietary driver. After
changing card was all fine. Card was checked for problems with some tests, all
were passed.

Yes, this is quite annoying.
I recall I upgraded Ubuntu and rebooted only to encounter this hang.
I can't even boot up some of the live CDs (Ubuntu, Linux Mint, ...) without
bypassing nouveau.
I've switched back to the proprietary driver and everything is fine.
But we need to get to the bottom of this.

The nouveau driver does not appear to provide acceleration (at least for the
moment) with GT240 cards.  You can get X to start, however, by using

Option "NoAccel" "true"

In your X config.

It is painfully slow though, so the only real option is to use the proprietary
NVidia driver.

The KMS/Nouveau framebuffer works as well, but again without acceleration, I
have a copy of the dmesg output as it loads the driver and will upload if it
will be useful; I guess the devs know of this issue with GT240's though.

You might want to actually post a recent kernel log showing your problem,
because the developers won't get anywhere with vague descriptions.

Also following up on your mailinglist post:
there is no general problem with nouveau and nv92, which is one of the most
common chipsets and works without problems for the most of us.

So you have to be more specific about what problems you do encounter in order
to get real help.

I'm trying to customize a live system based on Debian and it has encoutered
the
same issue with GT240 card. It seems that it works fine with other nVidia
cards. But only for GT240, it simply boots and freezes when booting into X
system.

If you need any logs, please let me know how to get them.

Perhaps it would be better if the default for GT240 was noaccel? There seems to
be a lot of bugs reported against it not booting.

I posted here since this is the earliest bug I found at freedesktop. I posted
the details about my card in bug 41333 earlier.

I have so far found these other reports:

That is the right kernel. Can you describe exactly what it is that you can
reproduce? Logs? etc. See http://nouveau.freedesktop.org/wiki/Bugs/ for what we
need.

[I know some of the bugs I marked as a dup of this one had that for old
versions, but I'd still like to see updated info.]

GPU locks up when nouveau module is started with KMS enabled. It is no longer
possible to start X in this case but the ttys are still usable.

Wow, so right on boot:

[   15.643599] [drm] Initialized nouveau 1.1.1 20120801 for 0000:04:00.0 on
minor 0

It locks up before the probe is even done! One thing to check -- do you have
any old firmware in /lib/firmware/nouveau? You shouldn't need any firmware
to
run nva3 (except the video firmware if you want vdpau).

Also, could you produce a log with

drm.debug=14 nouveau.debug=trace

That might provide more info as to what's going on.

There is certainly no firmware in /lib/firmware/nouveau.

So, Stikonas's bug is due to PGRAPH not processing any commands .... ever.

I pushed his mmiotrace in the vbios repo for anyone willing to check what is
wrong in nouveau's way of setting up pgraph.

Still present in 3.13.2-gentoo. I found that -EBUSY returns from
nv50_fbcon_imageblit.
> what is wrong in nouveau's way of setting up pgraph.
Does it mean that the bug somewhere in nv50_grctx_generate? Just to be sure
that bug in this function, is it possible to replace it using data from
mmiotrace of nvidia driver? For me it is not obvious how to modificate
nv50_grctx_fill in that case, what nv50_grctx_init should write to *size and,
after all, may it help somehow?

initialize stuff for gddr5 ram

This patch is based on Andrew's mmiotrace. I saw a sequence of init that I
didn't see in other traces for working cards. Andrew -- would be interesting
if
you could check it out and see if it helps. The algorithm I came up with is
insane -- there has to be some sort of data-driven thing going on there, but I
couldn't work it out.

For people having issues, please do a mmiotrace of the blob loading on your
card (see https://wiki.ubuntu.com/X/MMIOTracing for instructions), and send it
(xz -9'd) to mmio.dumps at gmail.com.

I might be able to test this patch in the middle of April. Sorry, I can't

For me, with this patch the problem is still present. I sent my mmiotrace
(NVIDIA Corporation GT215 [GeForce GT 240]).

I made this patch using my mmiotrace, but it doesn't help either.

maybe int off = offsets[o]; ?

looks like this condition is always false in this for-loop

Oh well. Indeed the values in your mmiotrace are different, but your and
Andrew's mmiotrace are the only traces I've seen that actually have the
writes
to those 0x10fxyz registers. (A few other traces have writes to the
similar-but-different DDR3 registers.)

And yes, I definitely did want to use offsets[o] in my patch.

Well, perhaps this 0x10f stuff has nothing to do with the issue. My observation
was that it seemed like for all the people it was broken for had GDDR5 ram,
which is why I went in this direction.

--- Comment #32 from jw.hendy at gmail.com ---
I'm trying like crazy to figure out why I have GPU lockups, but all the bugs
seem to dead end. What is the current status of this? More information, not
going to fix, unconfirmed? I have an NVA3 card (Quadro FX 1800M, GT215) which
cannot startx with acceleration, even with firmware.

Let me know if that's applicable to this bug and how I can provide
information,
if so. For reference, I'm on Arch 64bit. Trying to track down similar bugs
to
decide if I'm a duplicate issue or if I should start a new report.

noise example

In glxgears on some frames appears color noise, and it disappears or changes on
next frame.
Noise appears at some frames in glxgears, and it disappears or on next frame.
Same style noise may appear (shuffled pixels) while scrolling in Firefox or
switching tabs.

I applied that patch to Ubuntu Trusty 3.13.0-38.65, and it gives a huge
improvement. X no longer crashes on startup, and 3D acceleration works.

However I also get the glitchy noise a few times a second, except when showing
a static image. It is all over the screen, and sometimes appears as triangles.

Running glxgears and Firefox at the same time also starts giving errors in the
kernel log pretty quickly.
