[PATCH 0/2] drm/nouveau: option for staging ioctls and new SET_TILING ioctl
This patchset proposes to introduce a "staging" module option to dynamically
enable features (mostly ioctls) that are merged but may be refined before
they are declared "stable". The second patch illustrates the use of this
staging option with the SET_TILING ioctl, which can be used to specify the
tiling options of a PRIME-imported buffer.
The staging parameter will allow us

Hey Alex,
I've got no specific objection. But I'm curious as to why you took
this approach as opposed to just adding "if...

[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
