* rfnoc: add rx and tx transports, and amend rfnoc_graphCiro Nishiguchi2019-11-261-8/+13
| | | | | | | | | | | | | | | | | | | | | | | 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: Add tracking of 'valid' bit to propertiesAlex Williams2019-11-263-17/+74
| | | | | | The valid bit helps prevent placeholder defaults from being propagated through the graph. Values that are not valid will not be forwarded.
* rfnoc: Enable users to query connections in the graphAlex Williams2019-11-261-11/+19
| | | | Implement uhd::rfnoc::rfnoc_graph::enumerate_*_connections()
* rfnoc: Add clock selection to blocksMartin Braun2019-11-263-17/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | During registration, blocks must now specify which clock they are using for the timebase (i.e., for timed commands) and for the ctrlport (this is used to determine the length of sleeps and polls). For example, the X300 provides bus_clk and radio_clk; typically, the former is used for the control port, and the latter for the timebase clock. Another virtual clock is called "__graph__", and it means the clock is derived from property propagation via the graph. The actual clocks are provided by the mb_iface. It has two new API calls: get_timebase_clock() and get_ctrlport_clock(), which take an argument as to which clock exactly is requested. On block initialization, those clock_iface objects are copied into the block controller. The get_tick_rate() API call for blocks now exclusively checks the timebase clock_iface, and will no longer cache the current tick rate in a separate _tick_rate member variable. Block controllers can't manually modify the clock_iface, unless they also have access to the mb_controller (like the radio block), and that mb_controller has provided said access. This commit also adds the clock selection API changes to the DDC block, the Null block, and the default block.
* rfnoc: Add shutdown feature to blocksMartin Braun2019-11-262-0/+36
| | | | | | | | On destruction, the rfnoc_graph will call shutdown() on all blocks. This allows a safe de-initialization of blocks independent of the lifetime of the noc_block_base::sptr. Also adds the shutdown feature to null_block_control.
* rfnoc: register_iface_holder: Add ability to invalidate and updateMartin Braun2019-11-261-0/+3
| | | | | This lets child classes of register_iface_holder change the register interface, or even invalidate it.
* rfnoc: noc_block_base: Store property tree reference from make_argsMartin Braun2019-11-261-0/+13
|
* rfnoc: Add check_topology() API to nodesMartin Braun2019-11-261-0/+28
| | | | | This API lets blocks decide if their current topology is OK for them, and make decisions based on their topology.
* rfnoc: rfnoc_graph: Add API to query the number of motherboardsMartin Braun2019-11-261-0/+1
|
* rfnoc: enumerate and construct block controllers, enable connect()Brent Stapleton2019-11-261-8/+15
| | | | | During construction of the rfnoc_graph, enumerate all of the connected blocks, construct their controllers, and store them in the graph.
* rfnoc: Add null block controllerMartin Braun2019-11-262-0/+89
|
* rfnoc: noc_block_base: Pass args into block on constructionMartin Braun2019-11-262-0/+11
| | | | | These args come from the framework, e.g., because the UHD session was launched with them.
* rfnoc: graph: Add commit/release APIMartin Braun2019-11-261-0/+16
|
* rfnoc: noc_block_base: Add API to reduce num portsMartin Braun2019-11-261-0/+33
| | | | This allows blocks to reduce the number of actual, available ports.
* rfnoc: Add mb_controller APIMartin Braun2019-11-266-0/+415
| | | | | | | | | The mb_controller is an interface to hardware-specific functions of the motherboard. The API works in two ways: - The user can request access to it, and thus interact directly with the motherboard - RFNoC blocks can request access to it, if they need to interact with the motherboard themselves.
* rfnoc: Add radio block controllerMartin Braun2019-11-262-0/+689

* rfnoc: Added src port, EPID getters to register_iface, 64-bit callsAshish Chaudhari2019-11-261-1/+62
| | | | - Add peek64() and poke64() convenience calls
* rfnoc: noc_block_base: Handle the tick_rate property internallyMartin Braun2019-11-262-0/+36
| | | | | | | | | | | All noc_block_base derivatives are now plugged into the tick rate system. Connected nodes can only have one tick rate among them. This implies there is also only ever one tick rate per block. set_tick_rate() is a protected API call which can be called by blocks such as radio blocks to actually set a tick rate. Other blocks would only ever read the tick rate, which is handled by the get_tick_rate() API call.
* rfnoc: node: Add API to query and set edge propertiesMartin Braun2019-11-262-7/+50
|
* uhd: add new transport interface and base class implementationCiro Nishiguchi2019-11-262-0/+70
| | | | | | | | | | New interface aimed to replace zero_copy_if for new code, including new RFNoC development and redesign of streamer objects. Generic implementation of send and receive transport interfaces to allow reuse by various transport types. Derived classes implement transport-specific functions that are invoked by the base classes through CRTP.
* rfnoc: Add default block controllerMartin Braun2019-11-263-5/+30
| | | | | The default block controller should get instantiated when no other suitable block controller can be found.
* rfnoc: Add DDC block controllerMartin Braun2019-11-262-0/+136
|
* rfnoc: Added clock_iface to convey info about clocksAshish Chaudhari2019-11-261-0/+3
| | | | | The inteface provides a mechanism for users of clocks to query information such as the running status or rate
* rfnoc: Use RTTI "serialization" for stream commandsMartin Braun2019-11-261-6/+20
| | | | | | | | A small modification to rfnoc::action_info makes it polymorphic, and instead of serializing data structures into a string, this allows creating custom action objects and identifying them via RTTI. The stream command action object is a good example for how to use this, so all the usages of stream command action objects were converted to this scheme.
* log: Add convenience macros for logging from RFNoC blocksMartin Braun2019-11-261-0/+7
|
* rfnoc: Add rfnoc_graph classMartin Braun2019-11-262-0/+234
| | | | This replaces device3() for RFNoC applications.
* rfnoc: Move graph_edge data structure to its own header, add to_string()Martin Braun2019-11-262-0/+87
| | | | | | | | This structure represents information about a graph edge. Required by detail::graph and rfnoc_graph. graph_edge_t::to_string() will now provide a textual representation of the edge.
* rfnoc: Change Block-ID format to 0/FFT#1Martin Braun2019-11-262-17/+19
| | | | | | | Previously, it was 0/FFT_1. The counter was separated by an underscore. Now, we separate by a # symbol to allow for underscores in block names. This means 'FIR_Filter' is now a valid blockname.
* rfnoc: Add block registry/factory and make_argsMartin Braun2019-11-264-2/+143
| | | | | | - noc_block_base now has a ctor defined - The registry stores factory functions to the individual Noc-Block implementations
* rfnoc: Add block_poke support to reg_iface async msgAshish Chaudhari2019-11-261-1/+2
| | | | | The async message callback now has a vector of data words instead of a single one
* rfnoc: add register_iface holder classMartin Braun2019-11-262-2/+42
| | | | | | | | | Adding mixin class that manages holding onto a register_iface. Deriving from this new class in noc_block_base, as it needs access to a register_iface. Co-authored-by: Brent Stapleton <brent.stapleton@ettus.com>
* rfnoc: Added impl for reg_iface and ctrl_endpointAshish Chaudhari2019-11-262-0/+223
| | | | | | | | - Added new register_iface class that translates high-level peek/poke calls into CHDR control payloads - Added new chdr_ctrl_endpoint class that emulates a control stream endpoint in SW. It can create and handle multiple register interfaces

* rfnoc: Add action APIMartin Braun2019-11-264-17/+187
| | | | | | | | - Added action_info class - Allow to send actions from node to node - Allow to post actions into nodes - Allow to set default forwarding policies - Added unit tests
* rfnoc: Refactored CHDR packet interfacesAshish Chaudhari2019-11-264-592/+0
| | | | | | | - Moved packet interface code from public to private include - Split packet interface into two files: payload paring and packet iface - Added support for all CHDR packet types - Added more test cases to unit test
* rfnoc: Add property propagation, Boost.Graph storageMartin Braun2019-11-262-26/+247
| | | | | | | | | | | | - Adds a detail::graph_t class, which handles the propagation - Adds methods to node_t to aid with propagation - Adds unit tests - Adds dynamic property forwarding: Nodes are now able to forward properties they don't know about by providing a forwarding policy. A good example is the FIFO block which simply forwards most properties verbatim. - node: Temporarily disabling consistency check at init
* rfnoc: Add noc_block_base classMartin Braun2019-11-261-0/+92
| | | | This is a parent class for all block controllers.

| | | | This is a generic CHDR interface that abstracts out the bus width.
* rfnoc: Add properties, nodes, and accessorsMartin Braun2019-11-267-0/+712
| | | | | | | | | | | | | | Adds the following classes: - uhd::rfnoc::node_t, the base class for RFNoC nodes - uhd::rfnoc::node_accessor_t, a class to access private properties - uhd::rfnoc::res_source_info, a struct that identifies where properties come from - uhd::rfnoc::property_t, and property_base_t (its parent) - uhd::rfnoc::prop_accessor_t, a class to access properties Add always dirty property (dirtifier). Also adds unit tests for properties.

* gain groups: FormattingBrent Stapleton2019-11-261-1/+1
| | | | Applying formatting in anticipation of upcoming changes.
* gain_groups: Add zero-value gain groupsBrent Stapleton2019-11-261-0/+7
| | | | | | | | | | | | | | | Add convenience factory for making a gain group that has a single zero-valued element. This factory requires a name, which should probably be ALL_GAINS, or something similar (these constants are device-specific). Using this new make_zero factory in the X300 radio control when we don't find any gain elements so that our gain groups aren't empty. This simplifies our later setters/getters because we know that we'll always have _something_ cached. Note that we only register this zero value gain group for TX, as our ADC is registered as a gain element, so our RX gain groups are never empty.
* uhd: Add thread affinity utility functionsAaron Rossetto2019-11-261-0/+6
|
* utils: cast: Add from_str() typecastMartin Braun2019-11-261-1/+20
| | | | | This is the inverse to std::to_string(), and we can overload it with UHD-internal types.
* soft_register: Replace boost::unordered_map with std versionMartin Braun2019-11-261-2/+2
| | | | This is the only occurrence of boost::unordered_map in UHD.
* utils: soft_register: Remove 16-bit modeMartin Braun2019-11-261-14/+3
| | | | | This mode is never used, and makes it more cumbersome to maintain this code.
