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 channel recovery for Turing and for simple cases improves handling and reliability of recovery. I have been testing trivial OpenCL workloads and with this series have been able to recover from while(1) style GPU loops and bad pointer dereferences on a Turing GPU. However if there are less trivial tests available that have been known to cause problems with channel recovery in the past let me know and I'll start testing those as well.
