Looks like a nouveau driver issue — the SetSharedPixmapBacking member of its
ScreenRec is NULL.

I wonder if this is due to the fact that it's running in NoAccel mode. (Haven't
actually looked at any of the code though.)

Pacho, can you test 4.12-rcN with the nvidia-supplied firmware installed (part
of linux-firmware) which will allow you to have acceleration on your board?

Possibly, you might want something like

I tried already, but it's even worse because nouveau causes a kernel Oops when
running with acceleration and kernel 4.12-rc2... then, I needed to pass
nouveau.noaccel=1 and, even getting X started, I got the same crash
(additionally, I don't know why on kernel 4.12-rc2 my touchpad stops to move...
it clicks but doesn't move... but that is probably a different bug :( )

dmesg output with kernel 4.12-rc3

dmesg looks to contain lots of errors with kernel 4.12-rc3. I am using nouveau
1.0.15 and linux-firmware from 20170519

Thanks

gr fails to come up, and the rest of the board ends up dead too.

On the off chance you're running with a kernel setup aimed at you all of a
sudden needing to boot off some exotic RAID controller, thus needing to put
your modules into initrd... make sure that the updated linux-firmware is in
that initrd, because the originally-released firmware for GP107 was "wrong".

I don't know how that RAID is done... this is a Dell Inspiron 15 7000 laptop
that probably uses that setup to work with a small SSD as main device and a
bigger HD ... but this is working nice with kernel 4.9.x from 4.11 :/

I don't use any initrd... I could rely on CONFIG_EXTRA_FIRMWARE... but I
thought I didn't need that as nouveau is compiled as a module and not into the
kernel :|

OK, well if modules are loaded off the FS and not initrd, then you're good on
that front, assuming you really do have the updated linux-firwmare (April 4 or
later --
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=b14134583c2a15d4404695f72cb523daedb877ab).
Lots of people use initrd without understanding how it works.

So there are two issues here...

#1: we should probably disable reverse prime if you don't have acceleration (or
figure out how to make it work without accel... should just be a very slow
memcpy away... not great, but better than a non-working screen)

#2: we should figure out what's going on with accel on your GP107 -- looks like
stuff is just hanging (that's the "timeout" messages you see, we're waiting for
some condition to become true, and it never does).

I can help with the former, and hopefully Ben Skeggs can investigate the
latter.

Yeah, my linux-firmware snapshot is the one up to

This was indeed a different bug that got fixed in rc4 :)... but nouveau still
keeps failing in the same way with rc4 :(, do you need updated logs with that
kernel? (they seem quite similar though) Thanks

As a side note, I am still unable to run with "accel" enabled even with kernel

ping on this patch. It's not the solution for the underlying problem but at
least it's nice to have Xorg not crashing.

further investigation, it's unclear that it's OK to mess with
pScrn->capabilities in ScreenInit -- the other function does it in PreInit.

I did test it. But that was more than 1 year ago and I don't have the hw
anymore. So not sure what to suggest here.
