https://bugs.freedesktop.org/show_bug.cgi?id=101573

            Bug ID: 101573
           Summary: GP107 crash with no HDMI connected on 4.12.rc6
           Product: xorg
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau at lists.freedesktop.org

When starting the machine on Dell Inspiron 7000 (Kabylake, GTX 1050 Ti) with
HDMI monitor connected (HDMI output is provided by NVIDIA card, eDP is
connected to internal), everything seems to work (using reverse prime that is
automatically setup). There is lot of tearing, but it works.

But when starting the machine without HDMI output connected (so the NVIDIA card
has no connected output), it fails with timeouts:

Hi harry_x,

This timeout fault with the GP107 (nv137) is already being tracked in
bz#100228.

It's helpful that you've seen in testing that the NVIDIA card is brought
up
when a HDMI output is connected to it, but not when the NVIDIA card has no
connected output.

*** This bug has been marked as a duplicate of bug 100228 ***

This is actually reminiscent of an issue some laptops had a while ago where
without HDMI plugged in on boot, the board would be *totally off*, i.e. not
even on the PCI bus. And no real way that we could figure out to get it back...
after plugging in HDMI one had to do a pci bus rescan, and it would appear.

Probably worth checking if those other people don't have a similar
situation.

Hello Rhys and Ilia, 

thank you for your feedback. Is there anything I can do to help you track down
this issue ? I am senior C developer with kernel driver development experience,
but I know nothing of the NVIDIA card architecture, so I can't probably fix
it
myself...  But if there is anything how can I help with debugging of this
problem, I would be happy to help. Right now it works with NVIDIA BLOB, but I
am quite unhappy about the setup, I would much prefer to use open source driver
for many reasons...

I am not sure it is the same issue regarding PCI bus, I can see the device
normally in lspci -vv, but I don't know if that means anything...

Join us in #nouveau on irc.freenode.net. Unfortunately with these newer boards,
we understand very little about their initialization, esp wrt secboot.

Yeah, it's clearly a different issue. Just seemed a little reminiscent --
without HDMI plugged in, gr init times out because it feels like the GPU is
semi-off.
