dmesg output as I modprobe nouveau

Hopefully this isn't too similar or the same as #29171.  I have one of he new
11" MacBook Air machines (MacBookAir3,1) with the 320M chipset (PCI id 0x08a2,
NVAF I believe).

I'm booting in EFI mode using grub2, as this machine appears to have issues
setting up the SATA controller in BIOS emulation mode.  I've booted in BIOS
mode and done a dump of the video BIOS and int10 vector, which I'm loading via
grub2's "loadbios" command.

I'm running 2.6.37-rc2 with a bunch of hw-specific patches applied (as well as
a patch to boot in EFI physical rather than virtual mode, which unbreaks PCI),
the 16 Nov nouveau-drm snapshot from pq's webdir on people.fd.o, and
xf86-video-nouveau git rev 1143e7a.

First I modprobe nouveau.  Screen flashes, and it looks kinda garbled and
messed up.  I can vaguely see the cursor flashing, and I can ssh in.  I'll
attach dmesg output.  From that it looks like it's not finding connected
outputs, and it's using a fallback 1024x768 res (the LCD panel's native res is
1366x768).

From there I try to start X, and it looks like it has the same problem, unable
to find a connected output, and then the server segfaults.

Also possibly of note: I'm unable to get the nvidia proprietary driver to work
either (it just claims it can't initialize the card at all and bails).

Please let me know if there's any more information I can provide.

(Sorry about the mime-type fix spam...)

Not loading the vbios/int10 dumps in grub2 doesn't change anything... somehow
nouveau still finds a BIOS via PRAMIN?  nvidia proprietary driver still doesn't
work as well.

I also tried nv, but no luck ("Ignoring unsupported device 0x10de08a2 (GeForce
320M)").  Only thing I can get working is fbdev.

the bug which manifests as "illegal object class: 0x8597" was fixed by Ben
Skeggs almost 2 months ago (xf86-video-nouveau, commit
f1ac413d1d3dec2ccf63d4a8c79b9bd9ea578dcf), however it's unrelated to

Hmm then there must be a regression somewhere, as I'm running

Hmm so based on the raw DCB:

[drm] nouveau 0000:02:00.0: Raw DCB entry 0: 040001b6 0f220010
[drm] nouveau 0000:02:00.0: Raw DCB entry 1: 020112a6 0f220010
[drm] nouveau 0000:02:00.0: Raw DCB entry 2: 02011262 00020010
[drm] nouveau 0000:02:00.0: Raw DCB entry 3: 0000000e 0000000

It looks like the card is reporting 2 DP type outputs, and 1 TMDS output.  From
the parsing of the connector table:

[drm] nouveau 0000:02:00.0:   0: 0x00002047: type 0x47 idx 0 tag 0x08
[drm] nouveau 0000:02:00.0:   1: 0x00101146: type 0x46 idx 1 tag 0x07

It looks like the TMDS output is out of there... perhaps Apple just isn't using
it.  The two left are an eDP connector and DP connector.  It seems Apple is now
using eDP for internal display connections?  Interesting.

Then later:

[drm] nouveau 0000:02:00.0: expected bit 16 == 0, got 0x01114000
No connectors reported connected with modes

Uh oh.  This appears to be from nouveau_dp_auxch(). Unfortunately I'm not sure
I can puzzle out what all this is doing.  Presumably it's trying to query stuff
on the eDP port/connector, but that's failing...?

They are using it, the TMDS encoder is linked to the type 0x46 connector and is
used when using a DP->DVI adaptor.

Yes, that's correct, as are most vendors now.

It's failing for some reason yes, I'd need to look in more detail to figure out
why however.

Any progress on that?

FYI, Nouveau also fails to work when booting the MacBookAir3,1 (there's a few
variants, and I tried it on a 1,6ghz C2D processor, 4gb RAM, 128gb SSD) in BIOS
emulation mode. 

One gets a garbled output, both during the text boot sequence and when xorg
starts (with considerable color distortion). Consequently, one has to add the
"nomodeset" kernel option in order to boot.

The proprietary NVIDIA driver does work, however.

Shall I open a separate bug report for the 320M card failing to work on the MBA
31 in bios emulation mode? Which debug logs shall I provide, if any?

I confirm this two bugs, the one in EFI and the one in BIOS emulation.

I'm available for testing/investigating for EFI mode.

Let me try your patch ^^

dmesg kernel 2.6.37-rc6 video output corrupted in BIOS emulation


This is dmesg I made from last available kernel, this is a vanilla kernel (no
patch added) running on MacBookAir 3,1 in BIOS emulation. The screen is not
blank, I will try to decribe it :
 - on the left the screen is good over about 200 mm from left to right, then
there is garbage till 2/3 of screen, then blank. The garbage are readable
characters, but ugly.

It's lock like that hsync is wrong.

I didn't start X at all, I waiting for working console.

do mmiotrace is needed ?

In EFI the screen is mainly empty.

I can confirm this bug, and especially comment #10 - I have exactly the same
distortion in BIOS mode (not worrying about EFI here at the moment. As
expected, the binary blob NVIDIA drivers work just fine.

None of 2.6.35-gentoo-r5, or more importantly vanilla 2.6.37 or 2.6.36-rc7 work
with nouveau.

[Bug 31676] garbled text after loading nouveau module on EFI boot; X driver thinks there are no connected outputs

dmesg of last kernel with debug

I made a dmesg log with debug output.

The kernel used is a clone of git branch of nouveau patched with an updated EFI
physical mode (merge done by myself).

now the screen is garbage, probably due to the false output resolution
(1024x768).

The memory frequency reported mismatch nvidia-settings report :

nouveau report 405MHz or 450MHz, nvidia report : 532Mhz for the same card.

then the boot frequencies reported by nouveau drivers are totally break.

Your system has an IGP  - integrated graphics processor, with no
memory chips. Thus no memory clk is used nor set.

nvidia-settings reports the frequency of your system memory.
In some vbioses the memory clk for IGPs is set to 0 just to explicitly
confirm the above statement.

On nva[3|5|8|f] systems the get_clock() function does not always the
clocks correctly (looking at your shader frequency)

Hello,

I made some other tests. The conclusion is that, in bios mode nouveau have only
timing issue, the video outputs are detected properly but lines are not draw
properly. The issue is on line length which is unstable. I compared modeline
provided by nvidia and nouveau they seems to be equals, I do not check V/Hsync
and flags.

In EFI mode nouveau doesn't detect properly video outputs. it fail in detection
process.

Best regards

Hello,

I made more investigation with EFI boot, in particular I tryed boot kernel with
video=eDP-1:1024x768e to force to enable eDP-1. the result is that the screen
turn off (without "e" the screen show garbage and stay on). The other
interresting things is that I get a list of Modeline in dmesg. All of them are
rejected with error 15 (that seems to be MODE_VIDEO_HIGH define in kernel
sources) enstead of one with -3.

Another interresting thing is that the rejected Modeline with -3 is reported as
1368x768 but not the usual 1366x768.

I tryed to overide all sanity check to make all modes as MODE_OK. But the
screen still turn off at boot.

I Hope this help. If yes I can remake logs and put them here.

It appears that this bug report has laid dormant for quite a while. Sorry we
haven't gotten to it. Since we fix bugs all the time, chances are pretty good
that your issue has been fixed with the latest software. Please give it a shot.
(Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git
versions.) If upgrading to the latest isn't an option for you, your distro's
bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs
that haven't seen updates since 2011. If the original issue remains, please
make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/
for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
