GP107_regression_oops_log

Hi,
we have verified that commit eaa2c988033b ("drm/nouveau/gr/gp107: initial
support") is actually breaking the GTX1050TI on an Acer laptop.
It's not possible to reach Xorg anymore and the journal is filled with Oops as
shown in the attachment.

Thanks,

in that commit initial acceleration support for GP107 GPUs were added which
means there are more places to mess up. As a workaround you can boot with
nouveau.modeset=0 or nouveau.noaccel=1.

The real issue is something else, but this should give you at least a working
setup again.

Thank you, but since I have the hardware in my availability for the next week
or so I really would like if possible to help to debug better this issue and
maybe come up with a proper fix :)

Let me know if there is anything else I can provide that can help to debug this
issue.

Thanks.

Jul 11 16:15:01 endless kernel: nouveau 0000:01:00.0: timeout

So it's having trouble loading the firmware. Please confirm that you have the
latest firmware for gp107 (as there was a window of time when linux-firmware
contained bad firmware for gp107 -- some time ago now already, but you could
have a bad snapshot).

I believe I've seen this before though, also on a laptop. I see that it's using
the fancy new thing instead of ACPI DSM for powering it on:

Jul 11 16:14:58 endless kernel: VGA switcheroo: detected Optimus DSM method
\_SB_.PCI0.PEG0.PEGP handle
Jul 11 16:14:58 endless kernel: nouveau: detected PR support, will not use DSM

Can you try to boot in a way that forces the ACPI stuff to be used? I think
pcie_pm_port=off is the thing. And nouveau.runpm=0 for good measure.

The firmware is the latest one shipped in the linux-firmware git repo

>>> nouveau.noaccel=1 (see attachment)
In this case the nouveau module is correct probed and I do not get any WARNING
in the journal (even though a bit noisy on the PM part).

>>> only pcie_port_pm=off
The system hangs before reaching Xorg

>>> nouveau.runpm=0 (with or without pcie_port_pm=off) (see attachment)
Interestingly I can still reach Xorg but in the journal I have a lot of
WARNINGs

Looks to be a duplicate of https://bugs.freedesktop.org/show_bug.cgi?id=100228

Was going to mark as such, but wanted to hear the thoughts of imirkin or others
more experienced with nouveau first.

It is timing out on this line however, the same as bz#100228 which is also a
GP107:

nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 409800 [ TIMEOUT ]
