[RFC v4 00/12] drm/nouveau: Introduce CRC support for gf119+
Nvidia released some documentation on how CRC support works on their
GPUs, hooray!
So: this patch series implements said CRC support in nouveau, along with
adding some special debugfs interfaces for some relevant igt-gpu-tools
tests (already on the ML).
First - we add some new functionality to kthread_work in the kernel, and
then use this to add a new feature to DRM that Ville Syrj?l? came up

[PATCH v3 5/8] vdpa_sim: make devices agnostic for work management
Let's move work management inside the vdpa_sim core.
This way we can easily change how we manage the works, without
having to change the devices each time.

[PATCH v2 0/8] vdpa_sim: add support for user VA
v2:
- rebased on Linus' tree, commit ae3419fbac84 ("vc_screen: don't clobber
return value in vcs_read")
- removed `struct task_struct *owner` param (unused for now, maybe
?useful to support cgroups) [Jason]
- add unbind_mm callback [Jason]
- call the new unbind_mm callback during the release [Jason]
- avoid to call bind_mm callback after the reset, since the device
?is not

[PATCH v5 0/9] vdpa_sim: add support for user VA
This series adds support for the use of user virtual addresses in the
vDPA simulator devices.
The main reason for this change is to lift the pinning of all guest memory.
Especially with virtio devices implemented in software.
The next step would be to generalize the code in vdpa-sim to allow the
implementation of in-kernel software devices. Similar to vhost, but using vDPA
so we can reuse the
