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

GP10B is the chip used in Tegra X2 SoCs. This patchset adds support for its base engines after reworking secboot a bit to accomodate its calling convention better. This patchset has been tested rendering simple off-screen buffers using Mesa and yielded the expected result.
