* host: Update code base using clang-tidyMartin Braun2021-03-041-21/+18
| | | | | | | | | The checks from the new clang-tidy file are applied to the source tree using: $ find . -name "*.cpp" | sort -u | xargs \ --max-procs 8 --max-args 1 clang-tidy --format-style=file \ --fix -p /path/to/compile_commands.json
* uhd: Introduce I/O service managerAaron Rossetto2019-11-261-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | - Implement I/O service detach link methods - The I/O service manager instantiates new I/O services or connects links to existing I/O services based on options provided by the user in stream_args. - Add a streamer ID parameter to methods to create transports so that the I/O service manager can group transports appropriately when using offload threads. - Change X300 and MPMD to use I/O service manager to connect links to I/O services. - There is now a single I/O service manager per rfnoc_graph (and it is also stored in the graph) - The I/O service manager now also knows the device args for the rfnoc_graph it was created with, and can make decisions based upon those (e.g, use a specific I/O service for DPDK, share cores between streamers, etc.) - The I/O Service Manager does not get any decision logic with this commit, though - The MB ifaces for mpmd and x300 now access this global I/O service manager - Add configuration of link parameters with overrides Co-Authored-By: Martin Braun <martin.braun@ettus.com> Co-Authored-By: Aaron Rossetto <aaron.rossetto@ni.com>
* rfnoc: Use adapter_id_t for balancing load across linksAlex Williams2019-11-261-10/+19
| | | | | | | Since the mb_iface allocates local device IDs, also have it track the associated adapter IDs and provide a facility to retrieve them. Incorporate the adapter IDs in the user API to select the adapter for streamers.

* rfnoc: Centralize initialization state of SEPs to epid_allocatorAlex Williams2019-11-261-13/+12
| | | | | | | | | | | | | | | | Because the initialization state of SEPs is a graph-wide property, link_stream_managers and mgmt_portals cannot rely on their private members to determine if they can reset an SEP. Move the call to init SEPs into the epid_allocator, and have it call into a mgmt_portal to gain access to the SEP. Thus, link_stream_managers only request that an epid_allocator ensure an SEP is numbered and initialized, and they provide a path to communicate with the SEP. The epid_allocator will ensure init only happens once, so a stream currently running on another link_stream_manager does not get interrupted. This could happen, for example, if the OSTRM went to one device, and the ISTRM came from another. In general, EPIDs should only be assigned once.
* rfnoc: Use link_stream_manager's mgmt_portal for all mgmt packetsAlex Williams2019-11-261-6/+6
| | | | | | | | | | | | | Change data transports to use the mgmt_portal from the link_stream_manager. The initialization state of a device's EPIDs needs to be shared amongst all the SEP users. Otherwise, an RX transport may attempt to do a full reset of the SEP while TX is streaming (for example). TODO: The code contained here is not sufficient to handle multiple links that can access the same SEPs, as those would have different link_stream_managers, and thus, different mgmt_portal instances and views of the SEP state.
* rfnoc: add rx and tx transports, and amend rfnoc_graphCiro Nishiguchi2019-11-261-51/+43
| | | | | | | | | | | | | | | | | | | | | | | transports: Transports build on I/O service and implements flow control and sequence number checking. The rx streamer subclass extends the streamer implementation to connect it to the rfnoc graph. It receives configuration values from property propagation and configures the streamer accordingly. It also implements the issue_stream_cmd rx_streamer API method. Add implementation of rx streamer creation and method to connect it to an rfnoc block. rfnoc_graph: Cache more connection info, clarify contract Summary of changes: - rfnoc_graph stores more information about static connections at the beginning. Some search algorithms are replaced by simpler lookups. - The contract for connect() was clarified. It is required to call connect, even for static connections.
* rfnoc: Make a chdr_ctrl_xport using the new link APIsAlex Williams2019-11-261-47/+32
| | | | | | | | | | These changes add APIs to instantiate the new transports. However, only the control/management transport is currently implemented. It uses the chdr_ctrl_xport. Also update the mgmt_portal to use an ephemeral reference to the shared transport, to indicate that it has no ownership of the transport's memory.

* rfnoc: Added link/graph specific stream managersAshish Chaudhari2019-11-261-0/+266
- Fleshed out mb_iface - Managers currently only export ctrl APIs. Data APIs TBD
