Hi Anton,

There's a bug report already (bz#100228) that tracks support for the
GP107/nv137 chip. Take a look there for the software packages that you will
need.

As outlined by Ilia Mirkin, you will need at minimum (numbers are the mainline
version or Debian packages, not sure how Gentoo handles these):

Linux kernel >= 4.12
xf86-video-nouveau >= 1.0.15
linux-firmware >= 1.165
mesa git

This stack provides *preliminary* support for GP10x.

However, additionally for your XPS 9560 which uses the GP107, you will need to
get around a current ACPI bug.

There are reports of this ACPI bug affecting the graphics card regardless of
whether you use the proprietary nvidia driver or the open source nouveau
driver. So it's not a nouveau problem, but is causing the issues with soft
lockups.

You need to set acpi_rev_override=1 (any positive non-zero number works) in
your GRUB boot line. The kernel must have been built with
CONFIG_ACPI_REV_OVERRIDE_POSSIBLE.
