* 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'Brien2020-10-285-3/+218
| | | | | | | | | 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>
* 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: Move multi_usrp_python to its own moduleMartin Braun2020-10-122-191/+200
| | | | | This helps with recompilation times of UHD. No functional changes.
* 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.

* 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.
* lib: disable non pcie types in find with resourceSteven Koo2020-10-058-8/+49
| | | | | | | 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.

* E3xx: Add retry to loopback_self_testmichael-west2020-09-111-27/+46
| | | | | | | | | The loopback test sometimes fails. It was found that it would pass on a retry. The root cause of the failure is unknown at this time, but the retry allows the test to pass. This is intended as a temporary patch until the root cause of the failure can be identified. Signed-off-by: michael-west <michael.west@ettus.com>
* lib: Remove recursive locks in apply_correctionsmichael-west2020-09-041-3/+0
| | | | | | | | | There were locks in the apply_tx/rx_fe_corrections() methods that were acquired before calling methods that re-acquired the locks. The mutexes were not recursive, so it caused applications to lock up. The locks are unnecessary in the top level methods, so they are being removed.

* rfnoc: replay: Update packet size on mtu updateSteven Koo2020-09-031-5/+4
| | | | | | | | | | | Replay block would previously fail output on low mtu links because it was creating packets based on the default contruction mtu of 8192. This change will update the packet size when mtu gets updated. This also removes a warning for large packet sizes because the replay block uses a maximum packet size property. The block should be free to coerce down based on mtu limitations. Signed-off-by: Steven Koo <steven.koo@ni.com>

* dpdk: Improve link status detectionAaron Rossetto2020-09-032-16/+38
| | | | | | | | | | | | | | | | This change improves the DPDK link status detection algorithm in the following ways: - The status of the links are checked at an interval of 250 ms. If all links report as being up, the driver proceeds. - If any of the DPDK links has not reported as being up by the end of the link status detection timeout (1000 ms by default), the algorithm throws a runtime error rather than proceeds with one or more down links. - Users may override the default link status detection timeout by passing dpdk_link_timeout=N, where N is the desired timeout in milliseconds, either via device arguments or in the UHD configuration file.
* x300,mpmd: Increase recv frames for dpdk streamingSteven Koo2020-09-032-1/+16
| | | | | | | | With the default 32 frames, high rate DPDK streaming would overrun or drop samples. This defaults num_recv_frames to 512 for DPDK, which has shown to resolve these issues. Signed-off-by: Steven Koo <steven.koo@ni.com>

* uhd: Add APIs for getting the available power rangeMartin Braun2020-08-175-0/+55
| | | | | | | | | The previously added APIs for getting/setting power reference levels was missing an option to read back the currently available power levels (minimum and maximum power levels). This adds getters for TX and RX power ranges to multi_usrp and radio_control. The power API is thus now more similar to the gain API, which always had getters for gain ranges.

* fpga: lib: Change max FFT size to 1024Wade Fife2020-08-111-1/+1
| | | | | | | | | | | | | The max FFT size was 4096, but we don't currently have any devices that can do that without modification. This is because, currently, the FFT size must be the same as the packet size, and the largest packet size supported by most devices is about 8000 bytes, or 2000 sc16 samples. Therefore, the largest FFT size supported without modifying other code is 1024 samples. This change frees up about 21% of the LUTs and 36% of the BRAM used by axi_fft and makes the software block controller and the IP agree on the maximum FFT size.
* rfnoc: Don't error when streamer isn't foundSteven Koo2020-08-111-8/+0
| | | | | | This commit resolves an issue where the disconnect call would fail if the streamer was created, but not connected. If disconnect gets called on a streamer that isn't on the graph, ignore it.
* rfnoc: Resolves streamer/link segfaults on pythonSteven Koo2020-08-113-23/+32
| | | | | | | | | This commit resolves a segfault that occurs during teardown. Since teardown isn't detereministic in python, there were cases where the graph would destruct before the streamers or links got chance to cleanup. This would result in a segfault. This change gives the lambda a shared pointer to the object the callback method is calling on, so that it won't destruct before being called.
