* sim: Implement Sim > UHD Flow ControlSamuel O'Brien2020-10-283-34/+85
| | | | | | | This commit adds flow control support when streaming data from the Simulator to UHD. It no longer ignores STRS packets. Signed-off-by: Samuel O'Brien <sam.obrien@ni.com>
* sim: Move Hardware Specific to Config FileSamuel O'Brien2020-10-288-66/+149
| | | | | | | | This commit moves various magic numbers and hardware specific settings into the configuration file. It also provides default presets for said configuration files which can be inherited from. Signed-off-by: Samuel O'Brien <sam.obrien@ni.com>
* sim: Implement UHD > Simulator Flow ControlSamuel O'Brien2020-10-281-18/+47
| | | | | | | | | When sending data to the simulator, python simply cannot process the data as fast as UHD can send it. Flow control ensures that uhd doesn't overwhelm the simulator. Simulator > UHD flow control isn't implemented yet. Signed-off-by: Samuel O'Brien <sam.obrien@ni.com>
* sim: Support Timed StreamsSamuel O'Brien2020-10-282-1/+10
| | | | | | | | The only difference between a standard and timed stream is that the first data packet of a timed stream contains a timestamp. This commit adds the necessary fields to StreamSpec to accomplish this. Signed-off-by: Samuel O'Brien <sam.obrien@ni.com>
* sim: Integrate simulator into UHDSamuel O'Brien2020-10-288-5/+293
| | | | | | | | | 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>
* sim: Support Configuration FilesSamuel O'Brien2020-10-285-9/+68
| | | | | | | | This commit adds support for configuration files to the simulator. As of now, these files only change the source and sink of data samples, but they are easily extensible to add more configuration to the simulator. Signed-off-by: Samuel O'Brien <sam.obrien@ni.com>
* sim: Support StreamingSamuel O'Brien2020-10-288-348/+860
| | | | | | This commit add support for both Tx and Rx streams to the simulator. Signed-off-by: Samuel O'Brien <sam.obrien@ni.com>
* DUC: Fix incorrect DDS_GAINmichael-west2020-10-261-1/+1
| | | | | | | Fixes incorrect value for the DDS_GAIN that was causing the TX output power to be 6 dB lower than it was supposed to be. Signed-off-by: michael-west <michael.west@ettus.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.

* graph: Serialize all graph-related functionsAaron Rossetto2020-10-222-8/+13
| | | | | | | | This commit expands the scope of the former _release_mutex, renaming it _graph_mutex and ensuring that all graph modification functions are serialized against each other. This ensures that callers to graph_t's public functions are always operating on a coherent view of the underlying BGL graph object.
* graph: Re-fetch dst_node descriptor after src_node potential removalAaron Rossetto2020-10-221-0/+3
| | | | | | | | | | | | | | | | | The graph_t::disconnect(src_node, dst_node) function removes connections (edges) from src_node to dst_node in the graph, and then removes the nodes (vertices) if their degree is zero after removing the connections. Because removing a vertex from the graph invalidates vertex descriptors, the graph_t::_remove_node() function resynchronizes the node-to-vertex descriptor map after removing the vertex. However, in graph_t::disconnect(), the vertex descriptor corresponding to dst_node was not being refetched after the potential removal of src_node, which results in the incorrect removal of innocent nodes under certain circumstances. This commit ensures that the node-to-vertex descriptor is reconsulted for the vertex descriptor corresponding to dst_node before removing it from the tree.

* python: Add access to the property_tree from PythonMartin Braun2020-10-167-0/+96
| | | | | | | Example: >>> usrp = uhd.usrp.multi_usrp("") >>> tree = usrp.get_tree() >>> print(tree.access_int("/name").get())
* uhd_images_downloader: Add environment variable for http authLane Kolbly2020-10-154-3/+79
| | | | | | | | | This allows the image downloader to download files from restricted sources using HTTP basic auth, specifying the credentials in the UHD_IMAGES_USER and UHD_IMAGES_PASSWORD environment variables: ``` UHD_IMAGES_USER=lane UHD_IMAGES_PASSWORD=MyS3cretPassword uhd_images_downloader.py ```
* uhd_images_downloader: Remove unused default_no parameterLane Kolbly2020-10-151-3/+2
| | | | | This parameter isn't used by any callers of the function. Additionally, it doesn't actually change the default answer.
* mpm: Add dependency on pyusrp_periphs to MPMLane Kolbly2020-10-151-1/+1
| | | | | This change makes it so that changing the USRP periphs will cause a `make install` to reinstall the libpyusrp_periphs.so library.
* utils: Improve NMEA string outputmichael-west2020-10-121-47/+42
| | | | | | | | | | Separated output of GPGGA and GPRMC strings into separate try/catch so each one would display independently. Resolves issue of GPGGA string not displaying on devices that don't support the GPRMC string. Also removed unnecessary uses of boost::format. Signed-off-by: michael-west <michael.west@ettus.com>
* python: Move multi_usrp_python to its own moduleMartin Braun2020-10-123-192/+204
| | | | | This helps with recompilation times of UHD. No functional changes.
* examples: Fix --random option in benchmark_ratemichael-west2020-10-121-5/+11
| | | | | | | | The implementation was not properly configuring the stream command if the --random flag was used. It was especially bad when multiple channels were specified. Signed-off-by: michael-west <michael.west@ettus.com>

* deps: rpclib: Fix issue on socket closingMartin Braun2020-10-091-1/+7
| | | | | | | The rpclib server session closes its socket, which can fail. In our case, we only use the server for some tests, and we close the server on process exit, so we let the error slide. Since we close servers in dtors, not doing so would occasionally cause SIGABRT.

* 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.

* sim: Clarify Naming of StreamsSamuel O'Brien2020-10-084-25/+27
| | | | | | | | | ChdrSniffer is renamed to ChdrEndpoint to clarify its function as the actual destination of chdr packets, rather than just an observer. TxWorker has been renamed to OutputStream and RxWorker has been renamed to InputStream to avoid ambiguities regarding Tx and Rx terminology. Signed-off-by: Samuel O'Brien <sam.obrien@ni.com>
* sim: Simulator CHDR Parsing and RFNoC GraphSamuel O'Brien2020-10-086-5/+1114
| | | | | | | | | This commit adds a simulated RFNoC Graph to the simulator. It is also able to process management and control packets which can traverse the graph and read from simulated registers. Stub callbacks for creating streams have been provided but are not implemented yet. Signed-off-by: Samuel O'Brien <sam.obrien@ni.com>
* sim: Embed MPM into libpyuhdSamuel O'Brien2020-10-073-1/+61
| | | | | | | When ENABLE_SIM and ENABLE_PYTHON_API are set, this commit embeds MPM (Built with -DMPM_DEVICE=sim) into the pyuhd package. Signed-off-by: Samuel O'Brien <sam.obrien@ni.com>
* sim: Add Daughterboard MethodsSamuel O'Brien2020-10-077-14/+130
| | | | | | | | This commit adds daughterboard simulation to the simulator. There is a sim_dboard class which registers it's methods with the rpc server. These methods are visible over mpm as well as the mpm_shell. Signed-off-by: Samuel O'Brien <sam.obrien@ni.com>
* sim: Lay Groundwork for SimulatorSamuel O'Brien2020-10-078-44/+376
| | | | | | | | | | | | | | | At this point, only about half of the mpm methods work on the simulator over the mpm shell, and it hasn't been tested with uhd at all. If you want to give it a try, first install all of the python dependencies of mpm (The simulator doesn't require libusrp or any of the C++ deps). In addition, running mpm on a desktop machine requires the python lib netifaces. Next, make an /mpm/build directory and open it. Run `cmake .. -DMPM_DEVICE=sim`, then `make`. Finally, run `python3 python/usrp_hwd.py`. You should be able to open another terminal and run `mpm/tools/mpm_shell.py localhost` to connect to the mpm server.

* mpm: Cleanup rpc_server.pySamuel O'Brien2020-10-071-5/+7
| | | | | | | | This commit fixes a spelling mistake, moves logic for checking if a connection is local to its own method, and calls gevent.signal.signal instead of its deprecated alias gevent.signal. Signed-off-by: Samuel O'Brien <sam.obrien@ni.com>

* ic_reg_map: Allow registers to be arraysMartin Braun2020-10-061-19/+114
| | | | | | | | | | This lets you declare registers like this: REG_NAME[ARRAY_LEN] ADDRESS[BITS] DEFAULT ENUMS The reg object will now carray REG_NAME as an array. So, you can do regs.REG_NAME[0] = VALUE;
* ic_reg_maps: Add common regmap template for PythonToni Jones2020-10-061-4/+88
| | | | | | | Add COMMON_PY_TMPL which is identical to COMMON_TMPL in functionality but generates Python syntax rather than C++ header syntax. Modify the generate function which will now determine if the destination regmap file is a Python file or not and will use the appropriate template.

* fpga: lib: Fix small packets stuck in 10 GbE TXAndrew Moch2020-10-051-3/+17
| | | | | | Any packet less than CUT_THROUGH bytes has a high chance of getting stuck in the TX FIFO of the xge_mac_wrapper. In cut-through mode we were waiting for CUT_THROUGH bytes before transmitting the packet.
* lib: disable non pcie types in find with resourceSteven Koo2020-10-059-8/+56
| | | | | | | mpmd find doesn't respect the "resource" arg hint and can be detected when "resource" is set. This results in incorrect device selection when using PCIe. This change adds detection for "resource" as a prefix in the device hints for mpmd and the other devices.

* lib: graph_utils: Error on single SEP edgeSteven Koo2020-09-251-10/+14
| | | | | It could be possible that we only find one SEP connected edge, which should be invalid.
* lib: graph_utils: Fix formatting and compiler warningsMartin Braun2020-09-251-13/+15
| | | | | | | | | | | The conditional setting of some variables lead the compiler to assume they might be used uninitialized. Circumventing compiler warning by initializing variables to a default value, even if that's not the right value (they will get set later). Also applied clang-format to the same code section. This fixes da1aeaeccc.
