[PATCH 00/11] drm/nouveau: Enable GP10B by default
From: Thierry Reding <treding at nvidia.com>
Hi,
the GPU on Jetson TX2 (GP10B) does not work properly on all devices. Why
exactly is not clear, but there are slight differences between the SKUs
that were tested. It turns out that the biggest issue is that on some
devices (e.g. the one that I have), pulsing the GPU reset twice as is
done in the current code (once as part of the power-ungate
