[PATCH 0/3] New instmem implementation for Tegra
Due to the lack of implicit synchronization between CPU and GPU on Tegra systems
(like what PCI provides for dGPUs), the instmem implementation of GK20A/GM20B
relied on the slow, legacy PRAMIN so that CPU accesses used the same path as
GPU, making sure we see the same data on both ends.
The recent Nouveau refactoring introduced acquire/release functions on instmem
that help us understand the

[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

From: Thierry Reding <treding at nvidia.com>
Hi Ben,
here's a revised subset of the patches I had sent out a couple of weeks
ago. I've reworked the BAR2 accesses in the way that you had suggested,
which at least for GP10B turned out to be fairly trivial to do. I have
not looked in detail at this for GV11B yet, but a cursory look showed
that BAR2 is accessed in more places, so the
