- drm/nouveau/gr/gf100-: virtualise tpc_per_gpc · e51f75d5
  Ben Skeggs authored May 08, 2018
```
GM20B now also shares the same code, as NVGPU shows it doesn't need
special treatment.

  Ben Skeggs authored May 08, 2018
```
Newer HW doesn't appear to send this event, which will cause long delays
in runlist updates if they don't complete immediately.

RM doesn't use these events anywhere, and an NVGPU commit message notes
that polling is the preferred method even on HW that supports the event.

- drm/nouveau/fifo/gk104-: require explicit runlist selection for channel allocation · a7cf0180
  Ben Skeggs authored May 08, 2018
```
We didn't used to be aware that runlist/engine IDs weren't the same thing,
or that there was such variability in configuration between GPUs.

By exposing this information to a client, and giving it explicit control
of which runlist it's allocating a channel on, we're able to make better
choices.

The immediate effect of this is that on GPUs where CE0 is the "GRCE", we
will now be allocating a copy engine running asynchronously to GR for BO
migrations - as intended.
