[v2,0/8] introduce name service announcement rpmsg driver

Message

Arnaud POULIQUEN Aug. 25, 2020, 4:48 p.m. UTC

The NS announcement is implemented by several backends, but could be
considered as part the RPMsg protocol. 
In this case it should be managed as a reserved rpmsg service and so
implemented on top of the rpmsg protocol.

This series introduces the rpmsg_ns driver that handles the name service
announcement. The virtio backend is updated in consequence to use this
service.

Applies cleanly on Bjorn for-next branch (ca69dba7f13a)

Main updates from V1 to V2:
- Integrate Mathieu's comments:
  - rework the rpmsg_create_channel and rpmsg_release_channel error management.
  - merge patch "[9/9] rpmsg: ns: name service announcement endianness"
    in other pathes.

V1: https://patchwork.kernel.org/project/linux-remoteproc/list/?series=327257
