dmesg from boot

Booting Linux 4.6-rc1 and Mesa 11.2/11.3 fails to load the nouveau driver on a
GTX 970M (6GB) on an MSI GS60 Ghost Pro 4K (i7-6700HQ). It spews out wonderful
messages like
[    2.146398] nouveau 0000:01:00.0: priv: HUB0: 10ecc0 ffffffff (1940822c)

[    2.154583] nouveau 0000:01:00.0: DRM: Pointer to flat panel table invalid

Attached is a dmesg from boot. The driver does just drop to the i915 driver so
the machine is usable, but whenever I run lspci or lshw or try to logout of the
X session, it hangs when it switches back to the nVidia GPU (the laptop has an
LED indicator showing which GPU is in use)

--- Comment #1 from Pierre Moreau <pierre.morrow at free.fr> ---
Nouveau is successfully loaded on your laptop, but it seems to fail when it
tries to wake up the NVIDIA GPU (if you look at the dmesg you linked, around
11sec, the NVIDIA GPU goes to sleep). You could try booting with
`nouveau.runpm=0` on the kernel command line, and see if you still get the
issue.
Do you have any dmesg from when it hangs?

IIRC, Alexandre Courbot sent a patch some time ago to fix an issue where the
driver would try to reload the signed firmware upong resume and fail, but I
would have guess it is included in 4.6-rc1.

In addition to the runpm=0 thing, please ensure that you have the appropriate
firmware installed for this GPU - it should be in linux-firmware.git by now
(nvidia/*). I don't see a message about nouveaufb, which could be due to how
you configured your kernel, but it could also be because you don't have the
firmware, and the user helper is kicking in and waiting 60 seconds for it to
fail out, so nouveau's not fully done loading by the time the runpm stuff
kicks
in. Just a theory.

I have the gm20x firmware from the linux-firmware repo installed.

I'll try that in a bit as well as try to get a dmesg when it hangs (not at
my
computer ATM) I see "NMI watchdog: BUG: soft lockup - CPU#0 stuck for
22s!"
when it hangs during a logout/shutdown but that's not particularly helpful.

dmesg while crashing

Here is the dmesg from when it crashes. I ran lshw and it seems that triggered
the nVidia card to start back up which caused the crash. With runpm=0 the
nVidia card is never powered off so it doesn't crash.

I have the same problem with a GM206, GTX 960. I have to recycle the computer
twice.

--- Comment #6 from Alexandre Courbot <gnurou at gmail.com> ---
Maybe these messages are pointing to the root of the problem:

[   51.608479] nouveau 0000:01:00.0: Refused to change power state, currently
in D3
[   51.683924] nouveau 0000:01:00.0: Refused to change power state, currently
in D3
[   51.700020] nouveau 0000:01:00.0: Refused to change power state, currently
in D3

If the device is still in D3 when we resume it, then accessing registers would
understandably result in a freeze. Devinit comes early enough in the resume
chain to make this plausible.

FWIW I can successfully suspend/resume (echo mem >/sys/power/state) a GTX
960,
but runtime PM works slightly differently.

I would like to enable runtime PM on my desktop GTX960 to repro this, but for
some reason I am failing - despite loading nouveau with "modeset=2
runpm=1", I
cannot see runtime PM kicking in and /sys/class/drm/card0/power/runtime_status
says "unsupported". What am I doing wrong?

Tentative fix

The attached patch *might* help with this issue, but I have no way to test it.

Rashed, Efrem, can one of you give it a try and tell us if it helps?

Dave, I tried adding the option you suggested, but it did not allow me to
enable runtime PM, sadly. /sys/class/drm/card0/power/runtime_status still
"unsupported" despite nouveau.ko being loaded with "modeset=2
runpm=1".

dmesg using tentative fix

Alexandre, using the tentative fix you uploaded it switches GPUs properly now.
Here is the dmesg from that since there are still some errors related to power
state in it. Also, for some reason lshw is returning this for the nVidia GPU
now:

*-generic
                description: Unassigned class
                product: Illegal Vendor ID
                vendor: Illegal Vendor ID
                physical id: 0
                bus info: pci at 0000:01:00.0
                version: ff
                width: 32 bits
                clock: 66MHz
                capabilities: bus_master vga_palette cap_list rom
                configuration: driver=nouveau latency=255 maxlatency=255

memory:b0000000-bfffffff memory:c0000000-c1ffffff ioport:e000(size=128)
memory:dd000000-dd07ffff

I don't know if that's related to this at all but before, if I set
runpm=0 and
run lshw, it would return the proper description (running it without runpm
would cause the system to hang)

Thanks Rashed. This looks better but something seems to be going wrong with
PCI. I'm pretty clueless about PCI/ACPI, so let's see if someone else
has
something to suggest...

I will not be able to test until later this afternoon. I have a GTX 960 as
PCI 01:00.0 and GTX 730 as PCI 02:00.0.
I will send over dmesg/journalctl -k.

I have the same issue with bbswitch (and maybe vgaswitcheroo too). Basically
this means that in d3cold we can't talke to the gpu and the information
isn't
cached or something like that.

So according to Karol's comment it seems like the issue might be fixed.
Rashed,
can you confirm that the GPU is operational after runtime resume with the patch
I posted?

I can confirm the driver no longer hangs on runtime resume, yes. I don't
know
how to offload to the GPU so I guess I can't say I know if its operational.

new dmesg during hang

I decided to keep testing this in case we missed something, and running lshw
twice in a row causes it to hang. I'm not sure what's up with it so
I've
attached the dmesg. It looks pretty similar to before, but that doesn't make
sense since Alexandre patched the original problem.

uhh the card seems pretty much messed up after resume, because several things
just fail.

--- Comment #19 from Tobias Jakobi <liquid.acid at gmx.net> ---
I think I'm seeing the same issue here on a Schenker XMG A506 notebook. The
NV
GPU is the dedicated one. AFAIK all display hardware is connected to the Intel
iGPU.

Kernel is vanilla 4.6.1. Actually this is the first kernel (and the first time)
that I try to use the dedicated GPU.

lspci:
01:00.0 VGA compatible controller: NVIDIA Corporation GM107M [GeForce GTX 960M]
(rev a2)

Without runpm=0 even just calling DRI_PRIME=1 glxinfo leaves the system
unresponsive shortly afterwards. SysRq still works though.

Going to attach the part of the log in a second.

Tobias, your issue might be different and is caused by an issue with a Windows
10-specific workaround in the firmware for your Clevo-based hardware (notice
the AML_INFINITE_LOOP in the PGON method). Workaround for you: add
acpi_osi="!Windows 2015" to your cmdline.

@Rashed, @Efrem Please attach the uncompressed acpidump output.

Chris Wilson reported a similar trace for an Acer Aspire VN7-791G.
https://lists.freedesktop.org/archives/nouveau/2016-July/025602.html

I found ACPI information in the BIOS firmware for your laptop from
https://us.msi.com/Laptop/GS60-Ghost-Pro-4K-6th-Gen-GTX-970M.html
It could be the same PCI problem that I and Tobias are experiencing, except
that our laptops hang in ACPI while Rashed's firmware does not check the
PCIe
link status in the ACPI firmware. Still digging...

HI guys .
The Bug  is similar with my graphics panic , so I add related logs here .
When I boot up system ,system will hang at nouveau driver panic , repeat print
nouveau driver  panic info , I must force down the system . 
If i add nouveau.runpm=0  ,system  can boot up normally  without panic .


My graphics : NVIDIA  GM107 


And the panic info is related to pci op.

--- Comment #26 from Orsiris de Jong <info at netpower.fr> ---
I too have a optimus laptop with GM107 / intel graphics card, and I have not
been able to use nouveau driver since I bought the laptop (using kernels 4.3.5
up to 4.8.10 on Fedora 23-25 x64).

I have searched for multiple solutions so far, and always finished by
blacklisting nouveau in order to be able to use that laptop.
I could not even able to launch lspci without rendering my system unresponsive
(process then takes 100% cpu and I get cpu softlocks)

I've tried nouveau.runpm=0 and well, I can at least boot without having
nouveau
totally disabled :)

When not using runpm=0, I get the following when launching lspci / or
DRI_PRIME=1 glxgears

[ 1470.121123] nouveau 0000:01:00.0: Refused to change power state, currently
in D3
[ 1470.193738] nouveau 0000:01:00.0: Refused to change power state, currently

[ 1470.205793] nouveau 0000:01:00.0: pci: failed to adjust lnkctl speed

So I guess the nouveau driver cannot send to sleep / wake my nvidia card for
whatever reason.

I am actually trying rely on the discrete graphics in order to reduce power
consumption by default.

I noticed that I can't use vgaswitcheroo in order to chose my primary
graphic
card. Also noticed the following error messages on boot.
[    1.795356] [drm] Initialized drm 1.1.0 20060810

So far, when I switch graphic cards, I get the following in dmesg:

[ 1174.921195] nouveau 0000:01:00.0: DRM: resuming kernel object tree...
[ 1174.921209] nouveau 0000:01:00.0: DRM: resuming client object trees...

[ 1317.637168] vga_switcheroo: client 0 refused switch

I guess that nouveau driver does not allow to disable the nvidia card when
runpm=0 is passed as argument ?

Anything I could try please ?

@Peter I have a MSI GE62 6QD (skylake i67-700HQ) which is on the list of both
links you gave me.
Using acpi_osi=! acpi_osi="Windows 2009", I can launch lspci, but the
system
freezes a minute or so later with 

[   92.249957] nouveau 0000:01:00.0: DRM: resuming kernel object tree...

followed by a cpu lock.

Is there any debug info I can provide ?

@Pablo I have tried pcie_port_pm=off alone or together with the acpi_osi boot
flags, but it doesn't seem to make any difference.

Hi,

I have the same problems with my new MSI GP62 6QF laptop.
It has a geforce gtx960m videocard. I installed fedora 25 on it. The only way
to login into the system (gnome) was to disable the nouveau powermanagement
with grub option nouveau.runpm=0.

I did manage to login into the system with option:
acpi_osi=! "acpi_os=Windows 2013"

In /sys/kernel/debug/vgaswitcheroo/switch is see the following:
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :DynOff:0000:01:00.0

But it looks like it is not working properly, i see the red light on the power
button, meaning the other card is active as well.

I also tried the option:

i915.modeset=-1 nouveau.runpm=-1, occasionally i can login, but the the system
freezes completely.

It this a kernel bug or nouveau bug?

Thanks.
