comments:
- While the BSP commit isn't applicable as-is, improving the VSP debugging
infrastructure is useful.
- This could involve, among other ideas:
- More error logging, controlled through dynamic debug
- Counting errors and logging them when stopping the VSP, or exposing the
counters through sysfs
- Upstream patch proposal goes in the right direction but needs some more work
