This makes nouveau recognise and report more kinds of PGRAPH errors, as well as prevent GPU lockups resulting from some of them. Lots of guesswork was involved and some part of this is probably incorrect. Some potential-lockuop situations are handled by just resetting a whole PGRAPH subunit, which doesn't sound like a "proper" solution, but seems to work just fine... for now.

Hi there, Resending these now that they've had some more polish and testing, and I heard that Ben's vacation is over :-) These patches work as a starting point for more explicit error mechanisms and better robustness. At the moment, when a job hangs or faults, it seems that nouveau doesn't quite know how to handle the situation and often results in a hang. Some of these situations

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

Second version of this patchset. Not many changes since first version - I hope this means the changes are not too controversial. Changes since v1: - Removed lookup for previous FW files in "nouveau/" - Went back to using request_firmware() since we only try to load one file Original cover letter follows: GM20B is the GPU of the upcoming Tegra X1 SoC. This series adds initial support

Hello everyone, GM20B is the GPU of the upcoming Tegra X1 SoC. This series adds initial support for it, based on a rework of the already-supported GK20A. It also introduces support for NVIDIA-provided firmware files, which is why I have added a few NVIDIA people who are relevant to this discussion. The first patch adds support for loading the FECS and GPCCS firmwares from firmware files
