[PATCH 0/5] Improve Robust Channel (RC) recovery for Turing
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

[REGRESSION] nouveau: Crash in gk104_fifo_intr_runlist()
Hi,
I am testing Linux v4.2-rc5 and I am sporadically getting crashes shortly after
startup in gk104_fifo_intr_runlist(). What I've found is that the 'mask' value
read from offset 0x2a00 comes back as '0xbad0da00'. This causes the 'engn'
variable to be assigned the value 9, which is invalid; then wake_up() is called
on an uninitialized waitqueue which causes the crash.
Reverting commit 1addc12648521d ("drm/nouveau/fifo/gk104: kick channels when
deactivating them") seemed to make the problem go away, although I can...

[RFC PATCH v2 0/5] More explicit pushbuf error handling
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
