This is an initial series of patches to improve channel recovery on Turing GPUs with the goal of improving reliability enough to eventually enable SVM for Turing. It's likely follow up patches will be required to fully address problems with less trivial workloads than what I have been able to test thus far. This series primarily addresses a number of hardware changes to interrupt layout and

From: Thierry Reding <treding at nvidia.com> Hi Ben, these are a couple of patches that are in preparation for adding GV11B support. The fundamental issue that these are trying to solve is that the GV11B is the first Tegra incarnation of the GPU where the aperture really matters. All prior generations would accept any of them. For dGPUs we usually allocate memory in VRAM, so the default

From: Jérôme Glisse <jglisse at redhat.com> (mm is cced just to allow exposure of device driver work without ccing a long list of peoples. I do not think there is anything usefull to discuss from mm point of view but i might be wrong, so just for the curious :)). git://people.freedesktop.org/~glisse/linux branch: nouveau-hmm-v00
