CV-Bowen opened a new pull request, #21375:
URL: https://github.com/apache/nuttx/pull/21375
## Summary
rpmsg_virtio, rpmsg_virtio_lite and rpmsg_port each walked the endpoint
list in their dump op and printed only the endpoint names. Move the walk
into a shared `rpmsg_dump_epts()` that also prints each endpoint's
address, peer address, reference count, priority and private data, which
is what is needed to tell a stuck or leaked endpoint from a healthy one.
## Impact
`rpmsg dump` prints more per endpoint. No API or Kconfig change.
## Testing
Host: Ubuntu 22.04.5 LTS x86_64, QEMU version 10.2.1, sim: cc (Ubuntu
13.1.0-8ubuntu1~22.04) 13.1.0, qemu-armv8a: aarch64-none-elf-gcc (Arm GNU
Toolchain 12.2.Rel1 (Build arm-12.24)) 12.2.1 20221205
`rpmsg dump all` on qemu-armv8a:rpserver now shows, for the virtio link:
```
