* uhd: Check for overflow after timeout buff readSteven Koo2021-01-213-24/+15
| | | | | | | | | | | | Error processing has been moved to another thread, so it's possible that consecutive recv calls may miss the signalling that an overflow occurred. We have no guarantee that the flag had been set by the time the second recv call to find the errors occurs. This adds another check for an overflow after calling _get_aligned_buffs with a min 1ms timeout. Hopefully this is long enough for the error to propogate, but it's not guaranteed.

* uhd_image_loader: Consume .lvbitx filesLane Kolbly2021-01-111-117/+237
| | | | | | | | | | | | .lvbitx files contain the device tree and the FPGA bitstream, so this change allows a user to download a .lvbitx to their device instead of having to juggle separate .bin and .dts files. If a .lvbitx file does not contain a .dts section for any reason, download will still succeed, and a warning will be printed that no dts file was found. This behaviour was chosen (over erroring) to mimic the existing behaviour when a .bin file is found but there is no corresponding .dts file.

* uhd: Split radio_control into rf_control interfacesLane Kolbly2021-01-1118-658/+940
| | | | | | These rf_control interfaces allow easier implementation of radio controls as well as allowing easier sharing of code for implementing e.g. gain_profile.
* Create C++ wrappers for MPM RPC callsLane Kolbly2021-01-116-37/+195
| | | | | | | | | This gives us type-safety, as well as allowing us to create unit tests for RFNoC radio_controls without having to create actual RPC servers and clients in the unit tests. This change also fixes a bug in mpmd_mb_controller::set_sync_source, where it was calling the wrong MPM function.
* docs: Remove reference to Python sixMartin Braun2021-01-081-1/+0
| | | | | six is no longer in use within UHD, this is a stray reference in the build documentation.
* uhd: revert "Check property type at access..."Steven Koo2021-01-084-54/+4
| | | | | | | | | | This change reverts cb9329a681552e6ac6277d16e1627afcbb23e637. The type checking is causing some conversion issues on clang/macos. The type_index checking doesn't work correctly across shared libraries and should not be relied on to verify type, since it can vary from compiler to compiler.

* devtest: optionally generate XML report when running devtestsJoerg Hofrichter2021-01-081-1/+13
| | | | | | | If the unittests are invoked with an extra argument -x, an XML report is generated. This depends on the python module unittest-xml-reporting (aka. xmlrunner).

* mpm: rpc server: Fix unclaim sequenceMartin Braun2020-12-211-8/+19
| | | | | | | | | | | | | | | | | | | Sequence is now: 1. Get _state lock 2. Kill reclaim timeout 3. Run deinit sequence 4. Clear claim token and session ID 5. Release _state lock Before, we were not locking the mutex, and the timer was killed after the deinit sequence. If the deinit sequence stalls for whatever reason, that doesn't have to cause a claimer loss to be reported. UHD will already have stopped the reclaim loop before unclaim() is called. In the stall case, it would also have been possible the to acquire a new claim while the deinit() is still running. This is prevented with the combination of actually acquiring the mutex (like claim() and reclaim() do) and moving the token/session ID clearing to the end.
* usrprio: catch exceptions if rpc data read failsSteven Koo2020-12-211-3/+17
| | | | | | | | | This is an unhandled exception case that can cause silent failures for detecting ethernet x310 devices if the niusrpriorpc service is enabled.

* rfnoc: Fix remote stream buffer formatWade Fife2020-12-211-0/+18
| | | | | | | | When configuring remote streams, we were setting the format at the source stream endpoint, but not at the destination stream endpoint. Therefore, the destination used the default or whatever it was set to during a previous run. This change sets the format at the destination stream to match the format of the source stream.

* mpm: rpc server: Remove Python2 compat codeMartin Braun2020-12-081-4/+1
| | | | | | | | MPM is Python3-only, but contains some remaining compatibility code for Python2. Because this code requires extra dependencies (like six) and could become obsolete in the future, we remove it to preempt that. No functional changes.
* python: Add find() to the Python APIMartin Braun2020-12-075-0/+34
| | | | | | | | | | | | This a mapping of uhd::device::find() into uhd.find() on the Python side. The uhd::device is intentionally not mapped into Python (prefer MultiUSRP or RfnocGraph instead), so the namespace is moved up one level. Example: >>> import uhd >>> # Now print the device args for all found B200s: >>> for dev_args in uhd.find("type=b200")): print(dev_args.to_string())

| | | | | | | | | | | This is a new API call, only available on Python, and only available for MPM devices (it is added dynamically). It returns an object that allows calling RPC calls in a Pythonic manner. Example: >>> rpcc = usrp.get_mpm_client() >>> print(rpcc.get_device_info()) # Will print device info, as returned # by uhd_find_devices

* mpmd: Export RPC token and mb_args to the property treeMartin Braun2020-12-043-0/+13
| | | | | | There are applications (typically for debugging purposes) which need access to the token and the mb_args. They are thus published via the property tree.

* multi_usrp_rfnoc: Serialize make_rfnoc_deviceAaron Rossetto2020-12-041-1/+24
| | | | | | | | | | | | | | | In certain execution environments (e.g. NI's LabVIEW), the instantiation of multi_usrp objects may execute in parallel in two different threads. As the RFNoC block instances are shared between the multi_usrp instances, there is a risk that threads racing to configure the initial state of the Tx and Rx chains may operate on inconsistent or incomplete views of the state of the RFNoC blocks that make up the chain, leaving them in an invalid state that leads to client-facing errors. This commit serializes calls to make_rfnoc_device to prevent creating multiple multi_usrp objects in parallel. It also creates a map of existing multi_usrp devices and returns the existing multi_usrp object if it exists.

* python: Make TuneRequest implicitly convertible from doubleMartin Braun2020-12-011-0/+1
| | | | | | | | | | This allows to do the following: >>> usrp = uhd.usrp.MultiUSRP(args) >>> usrp.set_tx_frequency(1e9) In the past, you would have to manually convert the frequency to a uhd.types.TuneRequest before passing it to set_?x_frequency(). This new behaviour makes Python match the C++ behaviour.
* python: multi_usrp: Let get_tree() return a raw pointerMartin Braun2020-12-011-1/+1
| | | | | | | | | | | | | | | | | | This changes the Python version of MultiUSRP.get_tree() such that it returns a raw pointer to the tree instead of returning the sptr. This fixes an issue where calling get_tree() will reliably cause a segfault during garbage collection, at least on some USRPs. The downside of this approach is that storing the return value from get_tree() can produce a dangling pointer when the underlying object is destroyed. It's still better than segfaults, and the recommended way to use get_tree() anyway is not to store the return value (unless it's in a local scope), but tack on property tree methods to get_tree() itself. Examples: >>> usrp = uhd.usrp.MultiUSRP('...') >>> usrp.get_tree().exists('/path/to/prop') # This is fine This change has no noticable API changes.

* python: Improve access to device_addr_tMartin Braun2020-11-232-1/+9
| | | | | | | | This makes two changes: - Add device_addr_t as a type that the Python property tree access can handle - Add a to_dict() call to device_addr_t (in Python) that will return a regular dictionary from a device_addr_t for a more Pythonic access.
* python: multi_usrp: Fix get_radio_control()Martin Braun2020-11-231-1/+1
| | | | | | | | This function was incorrectly wrapped into Python and would fail with Python saying it can't hold a reference to the radio block. This changes the wrapping into returning a raw pointer, but also makes the return value policy reference_internal so that garbage collection happens in the right order.

* graph: Restore default resolver callback at node removalAaron Rossetto2020-11-204-1/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default resolve callback behavior for a newly-instantiated `node_t` object resolves all dirty properties associated with the node, then marks the properties as clean. When the node is added to a graph, its resolver callback is updated to use the graph property propagation algorithm in `graph_t::resolve_all_properties()`, which is considerably more sophisticated and relies on the graph topology to do its work. When a connection between two nodes is broken via the `graph::disconnect()` method, nodes which no longer have incoming or outgoing edges (connections) are removed from the graph. Prior to this change, the removed node's resolver callback was left pointing at the graph property propagation algorithm. In certain use cases, this could result in unexpected client-facing behavior. Consider, for example, this code (incomplete and for illustrative purposes only) which creates a streamer on one transmit chain of a multi-channel device, destroys that streamer, then creates a stream on the other transmit chain. Attempting to set the TX rate on the first chain after destroying the streamer does not result in the expected rate change, despite the same code working correctly before creating the streamer: constexpr size_t CH0 = ..., CH1 = ...; uhd::usrp::multi_usrp::sptr usrp = uhd::usrp::multi_usrp::make(...); // Set a TX rate on both chains; this succeeds usrp->set_tx_rate(initial_rate, CH0); usrp->set_tx_rate(initial_rate, CH1); assert(initial_rate == usrp->get_tx_rate(CH0)); assert(initial_rate == usrp->get_tx_rate(CH1)); // Create a TX streamer for channel 0 std::vector<size_t> chain0_chans{CH0}; stream_args_t sa; sa.channels = chain0_chans; sa.otw_format = ...; sa.cpu_format = ...; uhd::tx_streamer::sptr txs = usrp->get_tx_stream(sa); // Destroy the first streamer (disconnecting the graph) and // create a streamer for channel 1 txs.reset(); std::vector<size_t> chain1_chans{CH1}; sa.channels = chain1_chans; txs = usrp->get_tx_stream(sa); // Now try to set a new TX rate on both chains usrp->set_tx_rate(updated_rate, CH0); usrp->set_tx_rate(updated_rate, CH1); assert(updated_rate == usrp->get_tx_rate(CH0)); // <--- FAILS assert(updated_rate == usrp->get_tx_rate(CH1)); The reason this fails is because the second call to `set_tx_rate()` on channel 0 internally sets the 'interp' (interpolation ratio) property on the DUC node via the call to the DUC block controller's `set_input_rate()` function. As the DUC node is no longer part of the graph, having been removed from it when the first streamer instance was destroyed, the graph property propagation algorithm doesn't 'see' the node with the dirty property, and the 'interp' property resolver callback is never invoked. As a result, the DUC's input rate property, which depends on the interpolation ratio value, is never updated, and thus calling the `get_tx_rate()` function to query the new rate of the TX chain results in an unexpected value. In fact, in this particular case, `set_tx_rate()` actually raises a warning that the TX rate couldn't be set, and a message is printed to the console. This commit remedies the situation by restoring the default resolve callback behavior for a node when it is removed from the graph. This allows the framework to be able to invoke the property resolver callback on that node when a property is updated, the expected behavior of a newly instantiated node.
