Nouveau - Feb 2017 - [PATCH] drm/nouveau/core: recognise GP107 chipset

From: Chris Chiu <chiu at endlessm.com>

This new graphics card was failing to initialize with nouveau due to
an "unknown chipset" error.

Copy the GP106 configuration and rename for GP107/NV137. We don't
know for certain that this is fully correct, but brief desktop testing
suggests this is working fine.

I believe what's missing at this point is a mmiotrace of the NVIDIA
driver to make sure that there's nothing different about this GPU. If
you can make one (see https://wiki.ubuntu.com/X/MMIOTracing for a
guide - should end up ~100MB uncompressed), please send a compressed
one to mmio.dumps at gmail.com or make available some other way.
