           Summary: nouveau: nv40 display corruption in framebuffer and X

live dmesg before X was started

When I start nouveau with 2D acceleration the framebuffer is unusable
(typically displays frozen contents of the last shutdown), but the keyboard is
responsive. Once X starts, the display is unreadable - anything to a tiled
staircase picture to a partially solid grey screen, with no mouse cursor, and
the keyboard locks up - no responsive from the caps/num/scroll locks keys,
however it DOES respond to Magic SysRQ. The machine itself doesn't seem hard
locked, though.

The syslog is spammed with tons of message from the nouveau driver complaining
about PFIFO_CACHE_ERROR, PFIFO_DMA_PUSHER: MEM_FAULT, INVALID_CMD,
CALL_SUBR_ACTIVE, etc  - varies wildly on each boot. Sometimes its only few
errors, sometimes tons of them, but the end result is the same. 

Tried with the nouveau git tree on freedesktop 2/23. using nouveau.nofbaccel=1
clears up the framebuffer corruption, but the X display corruption/lockups
still happen

Picture from the framebugger after the nouveau drivers loads with acceleration

Using the current (5/2/12) nouveau git -this is a picture from the framebuffer
when nouveau loads and acceleration is enabled - it displays the shutdown
screen from the previous boot and the display is frozen. It stay this way until
either the driver is unloaded or the GPU hangs and the fbcon code switches back
to software fbcon (dmesg displays "GPU lockup - switching to software fbcon").

After experimenting with a few kernels, acceleration works in the framebuffer
and X normally on 32-bit (x86) kernels; but not on 64-bit (amd64) kernels.

After playing with kernel command line, I've found the problem does not occur
in a 64-bit kernel if mem=2G is added the kernel command line (the machine in
question has 3G of RAM). The higher the mem above that, the great the chance of
corruption - its hard to tell exactly when its an issue because its
intermittent - sometimes it work, sometimes it doesn't, (So far, 5 attempts at
2G no failures on either X for the framebuffer, whereas one start at 2G + 80M
worked but the second time it did not)

I experience something similar on my notebook.

- AMD Turion CPU; 3GiB RAM; nVidia GeForce Go 6100 video controller

- was working fine with 64 bit Ubuntu 10.04 using nv X video driver

- problems on 64 bit Ubuntu 12.04 with nouveau driver (VESA driver works but
does not support native resolution)

Symptoms are various.  Simplest, on fully updated system: LightDM seems to work
to allow login but Unity desktop does not show up except for background.

dmesg shows a lot of messages like this (and variants):
 [drm] nouveau 0000:00:05.0: PFIFO_DMA_PUSHER - Ch 3 Get 0x01256038 Put
0x011c60b0 State 0x4ffe0004 (err: INVALID_MTHD) Push 0x00000000

/var/log/Xorg.0.log shows lots of mayhem after this message:
 [mi] EQ overflowing.  Additional events will be discarded until existing
events are processed.

Adding mem=2g to kernel seems to fix the problem!

Thanks Salah for this discovery!  Thanks xexaxo on #nouveau for recognizing my
problem and pointing me here!

I will attach logs.

ugly workaround

Does this patch help too? It's still a workaround, but it doesn't lose memory
above 2GB.

Marcin:

Thanks for the proposed patch.

I'm in "dumb Ubuntu user mode".  Would testing your patch be valuable to the
cause, valuable enough for me to learn how to learn how to rebuild Ubuntu
kernels, with patches?  (I've rebuilt CentOS kernels and long ago built
kernel.org kernels, but not debian or Ubuntu kernels.)

Is there a good test for "broken PCI/AGP" hardware?  I take it that there is a
lot broken at the 4G boundary but you suspect mine is broken at the 2G
boundary.

Possibly relevant factoid: the notebook is speced to accept 4G of RAM but won't
with this BIOS (the latest).  It will accept 4G with an older BIOS.  The
manufacturer (Acer) does not accept that this is a defect.

I had guessed (based on no evidence) that there was a sign-extension bug in the
nouveau code. That guess was based on the apparent fact that a 32-bit kernel
worked.

How do you distinguish hardware vs software bug?  Your patch should bypass
either.

I would have thought that a kernel parameter to set MAX_DMA32_PFN might be
useful.

Thinking some more.  Some inconclusive evidence that this is not a hardware
bug: 64-bit Ubuntu worked fine on it with 3G of RAM.  So to does the MS Windows
Vista.  This surely included DMAing into the high 1G by disk I/O, DVD writer
I/O, and video driver I/O.

What's new is nouveau.  Perhaps it uses part of the video controller that nv
and Vista do not, part that does defective DMA, but that isn't obvious to me.

(Note: I'm using "DMA" in the computer architecture sense, not the IBM PC clone
sense.)

The above "workaround" works. Framebuffer is OK, X is good, glxgears runs
without having to specify mem=2G (this is against the nouveau git).

I think it is buggy hardware - its just the blob and Windows driver know about
it and only do 31-bit DMA (or maybe they just get lucky). Attempting to set
dma_bits=31 in nouveau_vram_init cause nouveau_sgdma_init to mail to map the
page, and attempting to allocate a suitable page using pci_alloc_consistent /
dna_alloc_coherent or alloc_page GFP_DMA flag causes BUGs and paging faults.  

If I specify if I specify both nouveau.vram_pushbuf=1 AND nouveau.vram_notify=1
(just one alone does not work), it "soft of" works without mem=2G. The
framebuffer is OK. X is still distorted but not as badly and isn't locked up,
and the dmesg is no longer filled with errors, but glxgears does not work (it
doesn't crash but just shows crazy flashing triangles).

Salah:

If the limitation were in the hardware, why would the kernel arch (32 bit vs 64
bit) make a difference?  By the time that addresses get to the PCI bus, the
architecture should make no difference.

I talked to Ben about this bug at XDC2012 and he told me we are using
nv04-style virtual memory interface, because of some then unknown bugs in nv4x
implementation - and this is probably the reason why you are seeing this bug.

Since XDC, Ben fixed and enabled nv4x-style virtual memory in nouveau.git, so
please test it!

dmesg of new kernel

It runs FAR better - the distortion and lockups are gone, and the picture us
substantially better (on par with the blob).

Its not quite 100% - X crashes reliably if I switch to another VT, back to X,
and then use something with video acceleration (after it crashes and restart
its distored like before, but not locked up. If I apply the workaround in bug
31961, X still crashes but restarts withotu distortion)

Regardless of console switching, CACHE_ERROR start flooding the syslog but not
immedately, but there no noticable artfacts or slowdown.

For my system (reported Bug 54988) it starts up now and works for a RAM size of
3G.

But after logging into the gnome desktop the screen becomes blurry and 
and while trying to open any gnome menu, the screen gets scrambled now.
This is even a problem when i boot with mem=2G - this used to work with the
current version of the fedora driver in kernel 3.5.4.

Seems the DMA problem is gone, however some new bugs are showing up :-)

System Description is still the same as 54988. I am running a current fedora
kernel,patched with nouveau from 2nd October.


Linux version 3.5.4-2.localnouveau.fc17.x86_64 (root@baldur) (gcc version 4.7.2

You have allocated only 32MB of RAM for the GPU

Try bumping it to 128 or 256MB it should resolve your issue

dmesg|egrep -i 'drm|agp|fb'

I regularly encounter a similar trace as in the first attachment (attachment
57574) since I went from 1.5G RAM to 4G RAM using an NV34 [GeForce FX 5200].
(linux 3.6.0, xf86-video-nouveau 1.0.2)
It happens almost every day, by the end of the day, always during (basic)
graphical operation (eg: open a PDF viewer)

Judging from the errors, I'd say it can't look up the handle it created.

Diving into the old dma implementation seems 

The handles for vram and gart could not be looked up, so guessing an invalid
entry was used.

Does setting dma_bits = 32 inside drivers/gpu/drm/nouveau/core/subdev/vm/nv44.c
help?

The old nouveau driver seemed to have commented out the part about 39-bits
support for cards < nv50.

nouveau CALL_SUBR_ACTIVE errors using dma_bits=32 kernel on NV34

I tried your suggestion about setting dma_bits to 32 inside
drivers/gpu/drm/nouveau/core/subdev/vm/nv44.c.
but sadly the same issue arises (dmesg attached).
I hope I'm still wise to post those traces (from my NV34) in this bug report
and hope the root cause is common.
I currently use the drm kernel module with debug=2, debug=3 dumps too much
output, but let me know if this can provide additional useful info.

I should add that I've no problem with 3GB. Problem arises when I add 1 more

limit vm size to 31 bits (nv04-nv40,nv45)

Ok, original Salah's issue seems to be fixed. Xorg crashes and CACHE_ERRORs
look like separate bugs - please open new bug reports for them (note that for
CACHE_ERRORs I advise running nouveau git kernel with
http://lists.freedesktop.org/archives/nouveau/2012-December/011780.html).

Raphaël Droz's: you have nv34, so changing something in *nv44.c* obviously
won't fix anything for you... Does the above patch help?

As of kernel 3.7, xorg-1.13, nouveau DDX 1.0.4, mesa-9.0 all the errors related
to ths bug are gone for me - no distortion, no crashes, and no CACHE_ERROR,
even after switching VT and running accelerated programs for over a week.

I switched to 3.7.0 and I can't reproduce either. All seems stable with 4GB.
I'm confident, but I may need to do longer testing.

Note that I can consistently throw "nouveau: ib channel create, -22" messages
(eg: each time I run glxgears) but they seem harmless (and maybe even
unrelated)
