Not yet tested, although compiles w/o warnings. That's the only reason why it's marked as a WIP.

Required some minor restructuring, but the overall architecture is similar to the mainline ARTIQ code.

It's been tested - and in practical testing sometimes the playback status message would arrive at the same time a destination survey was sent - which didn't handle the PlaybackStatus, causing a proper playback to get timed out - e.g. in logs:

[   253.542360s]  INFO(runtime::kernel::core1): kernel starting
[   253.560816s] ERROR(runtime::rtio_mgt::drtio): [DEST#1] received unexpected aux packet: DmaPlaybackStatus { destination: 1, id: 2841472, error: 0, channel: 0, timestamp: 0 }
[   253.776500s]  WARN(runtime::rtio_mgt::drtio): [LINK#0] unsolicited aux packet: DestinationOkReply
[   263.554480s] ERROR(runtime::rtio_dma::remote_dma): Remote DMA await done timed out
[   263.582751s]  INFO(runtime::comms): peer closed connection

that should explain the last commit, as that fixes that oversight.

It's been tested - and in practical testing sometimes the playback status message would arrive at the same time a destination survey was sent - which didn't handle the ``PlaybackStatus``, causing a proper playback to get timed out - e.g. in logs: ``` [ 253.542360s] INFO(runtime::kernel::core1): kernel starting [ 253.560816s] ERROR(runtime::rtio_mgt::drtio): [DEST#1] received unexpected aux packet: DmaPlaybackStatus { destination: 1, id: 2841472, error: 0, channel: 0, timestamp: 0 } [ 253.776500s] WARN(runtime::rtio_mgt::drtio): [LINK#0] unsolicited aux packet: DestinationOkReply [ 263.554480s] ERROR(runtime::rtio_dma::remote_dma): Remote DMA await done timed out [ 263.582751s] INFO(runtime::comms): peer closed connection ``` - that should explain the last commit, as that fixes that oversight.
