* n320: Add correction APIs to radio_control objectMartin Braun2021-05-062-0/+63
| | | | | | | | | | The N320, like the X310, has some frontend corrections (IQ balance, DC offset) which can be controlled from software. The property tree entries exist for these, but the radio_control APIs do not (which also disables the multi_usrp APIs). This makes it harder to disable DC offset or IQ balance corrections from software, and disables our calibration utilities.
* multi_usrp_rfnoc: Fix get_device()->get_tree()michael-west2021-05-051-6/+3
| | | | | | | | | | | | | | | Property tree access via the device tree was resulting in a segmentation fault because the device::_tree member was not properly initialized for the redirector_device class. The redirector_device also had a get_tree() method that was not actually called because the get_tree() method in the parent class was not declared virtual and all calls to get_tree() were done on the parent class (i.e. get_device()->get_tree(). - Added initializer for device::_tree member in redirector_device class constructor - Removed redirector_device::get_tree() method Signed-off-by: michael-west <michael.west@ettus.com>

* rfnoc: Add option to disable flow control on rx streamingmattprost2021-04-295-49/+121
| | | | | | | | | | | Disabling this feature will allow the USRP to send a continuous stream of Rx data to a host machine without throttling due to lack of flow control credits. This is unnecessary overhead on lossless transports such as pcie or aurora. Usage: add 'enable_fc=false' to stream_args.args Signed-off-by: mattprost <matt.prost@ni.com>
* N320: Fix IQ mapping and frontend correctionsmichael-west2021-04-221-2/+4
| | | | | | | | Changed register offset from 4 bytes to 8 bytes. The registers in the frontend were not being properly addressed, so calibration, IQ mapping, and frontend corrections were not working properly. Signed-off-by: michael-west <michael.west@ettus.com>

* uhd: Fix radio_control-related method constnessMartin Braun2021-03-174-11/+11
| | | | | | | | | | | | | | | | | The const-ness of some radio_control differed between base class and implementation. This fixes the consistency, but also makes sure these methods follow the rules for when to make methods 'const'. The following rules apply: - Methods that query static capabilities are const. Here, we made get_tx_lo_sources() const (the RX version was already const). - Getters that may have to interact with the device (e.g., peek a register) are not const, because the act of peeking is usually also non-const. Here, we changed get_rx_lo_export_enabled() to non-const. - All base classes are fixed such that the derived classes and the base classes have the same const-ness. Clang was warning about differences. This can cause very tricky bugs, where the radio_control_impl version can get called instead of the intended child class.

* lib: Use const-ref in for loops instead of const-copyMartin Braun2021-03-045-6/+6
| | | | | | This is potentially a performance issue, even though it doesn't have a big impact in this context. Clang will warn about it, and this fixes the compiler warning.
* twinrx: Fix missing default copy ctorMartin Braun2021-03-041-0/+3
| | | | | | | twinrx_gain_config_t defined an assignment operator, but not a default copy ctor. This is not allowed in modern C++, although compilers let it slide and provide their own defaults. Clang, however, throws a warning so let's fix it.

* mpmd: Skip find if "resource" key is specifiedmichael-west2021-02-116-36/+13
| | | | | | | | | | | MPM devices were being discovered when trying to locate PCIe connected devices. Adding filter to exclude them if the "resource" key is specified in the device address arguments. Replaces "lib: disable non pcie types in find with resource" to reduce impact to older devices and remove API change. Signed-off-by: michael-west <michael.west@ettus.com>
* ADF535x: Change freq_resolution to mod2michael-west2021-02-041-4/+4
| | | | | | | | | The freq_resolution parameter to the set_frequency() method was confusing. Changing it to the mod2 value clarifies the intention and makes the math to reduce the FRAC2 and MOD2 values much easier to read and maintain. Signed-off-by: michael-west <michael.west@ettus.com>
* dboard_iface: Modify sleep() functionMichael West2021-02-041-5/+14
| | | | | | | | | The algorithm for the sleep() function is changed to first increment the command time if the command time is set. If the command time is not set, it just performs a sleep on the host. The intention is to make a best effort to create the requested delay on the device.

* 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.

* mpmd: Add support to delay and trigger fpga/dts load after updateVirendra Kakade2021-01-112-80/+130
| | | | | | | | | Add a new image_loader argument delay_reload to provide a way to update components but optionally delay the actual load. Similarly add a new argument, just_reload, to enable uhd to reload the fpga/dts components. Signed-off-by: Virendra Kakade <virendra.kakade@ni.com>
* uhd: Split radio_control into rf_control interfacesLane Kolbly2021-01-114-56/+7
| | | | | | 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 Kolbly2021-01-112-32/+25
| | | | | | | | | 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.

* 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: 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: 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.

* MPMD: Reduce max frame size for 10 GbEmichael-west2020-11-061-1/+1
| | | | | | | | | | | | MTU discovery is passing on sizes beyond the maximum size, which allows packets to exceed the default MTU size of 8000 set for 10 GbE. This can cause TX to stop when using higher sample rates. Reducing the maximum frame size to 7972 (8000 minus 28 bytes for UDP and IP headers) guarantees the packet size will never exceed the default MTU for 10 GbE.

* sim: Integrate simulator into UHDSamuel O'Brien2020-10-284-3/+197
| | | | | | | | | This commit adds a device::register_device which allows uhd to start up a simulator when uhd is called with the arguments type=sim. Creating the device object creates a subprocess using pybind and an embedded interpreter, and destroying the object cleans up those subprocesses. Signed-off-by: Samuel O'Brien <sam.obrien@ni.com>
* multi_usrp: Fix streamer destruction callbackmichael-west2020-10-221-91/+74
| | | | | | | | | | | | | | | | | The streamers were keeping a reference to the multi_usrp object, so the object would not destruct when the user deleted or reset the shared pointer to the object. An error would occur if the user attempted to make the same device and get streamers on it without explicitly deleting the streamers first. This change refactors the code such that the streamer destructor only depends on the existence of a weak_ptr to the underlying rfnoc_graph and a vector of edges returned by the connect function. It checks to see if the graph has been deleted before calling the functions to disconnect the edges. This allows the multi_usrp object and streamer objects to be destructed in any order.

* n310/n300: Allow gain coercionMartin Braun2020-10-091-2/+14
| | | | | | | | | | | | The N310 had a different behaviour from other devices, where setting a gain out of range would cause an assertion error. This is problematic for two reasons: 1) Assertion errors should not be triggered by public APIs (if we throw public APIs, we should give a clear error message), and 2) Setting gain and frequency has a coercing behaviour on all other devices. This changeset clips the gain before calling into the gain table lookup.
