* uhd: fixing MSVC warningsBrent Stapleton2020-01-092-7/+10
| | | | | | | | | | | Small changes to remove various compiler warnings found in MSVC - Adding uhd::narrow_cast to verious spots - wavetable.hpp: all floats literals in the wavetable. - paths_test: unnecessary character escape - replay example: remove unreferenced noc_id - adfXXXX: Fixing qualifiers to match between parent and derived classes - rpc, block_id: Removing unused name in try...catch
* examples: Add options to benchmark_rateMichael West2020-01-021-19/+39
| | | | | | | | - Add option for high or normal thread priority with default set to high - Add rx_delay and tx_delay options to dynamically set start delays (default of 0.25 seconds for TX and 0.05 seconds for RX) Signed-off-by: Michael West <michael.west@ettus.com>
* examples: benchmark_rate dpdk recv/send thread priority elevationmattprost2019-12-201-0/+13
| | | | | | | | | | Improves dpdk streaming performance for benchmark_rate by elevating thread priority of the send and recv threads. It does this conditionally, if use_dpdk=1 was passed in through the command line args. Admittedly, this is not a perfect solution, as it does not account for the case when a dpdk user is utilizing a config file to pass in that information. The scope of this fix does seem appropriate for an example.
* examples: gpio: Replace get_time_now() with steady_clock::now()Martin Braun2019-11-261-12/+17
| | | | | | | | | | The gpio example would continously call get_time_now() to time a loop. There is no need to query a device here, so we query the system timer instead. This fixes an issue where the large amounts of control traffic could slow down TX, causing the TX and FDX tests to fail. This was only ever seen on the X300_HG over 1GigE.
* examples: gpio: Fix minor issuesMartin Braun2019-11-261-3/+3
| | | | | - Use GPIO_BIT(x) instead of 1<<x where appropriate - Correctly use rx_buff/tx_buff in recv/send, respectively
* examples: benchmark_rate.py: Add ?x_stream_args argsMartin Braun2019-11-261-2/+9
| | | | | | | | | | | | | This allows adding stream args to the Python version of benchmark_rate in the same way as for the C++ version, e.g.: python3 ./benchmark_rate.py \ --args addr=192.168.40.2,num_poll_offload_threads=4 \ --rx_stream_args \ recv_offload=1,num_recv_frames=32,recv_offload_wait_mode=poll \ --tx_stream_args \ send_offload=1,num_send_frames=32,send_offload_wait_mode=poll \ [... other arguments ...]
* examples: gpio: Add note on which bank is being usedMartin Braun2019-11-261-0/+1
| | | | | This will print the currently-used GPIO bank's name before starting the test.
* examples: Send only single packets in test_messagesMartin Braun2019-11-261-3/+3
| | | | | | | | | | | | | | | | For the burst ACK test, test_messages would send 3 packets. However, that assumes that the underlying link is fast enough to send three packets in time, and some devices are hard to operate without underruns without also specifying a start-of burst timestamp. Often, test_messages would report that no ACK was received, but instead, an underrun was received. test_messages also doesn't need to send three packets. The three packets came from the "start of burst" flag, which no device in UHD supports. The change is thus to send a single packet with an EOB marker for the burst ACK test. This will work regardless of the link speed and CPU power.

* examples: gpio: Add --list-banks optionMartin Braun2019-11-261-0/+9
| | | | | | | The gpio example can now list all available banks before running tests. Use like this: gpio --args $args --list-banks
* examples: benchmark_rate: Add --rx_spp and --tx_sppMartin Braun2019-11-261-5/+23
| | | | These command line arguments control the spp values used for streaming.

* uhd: Replace all occurrences of boost::bind with std::bindMartin Braun2019-11-265-7/+11
| | | | | | | | | | | | | | | | | | | | | Note: Replacing everything with a lambda would be even better, but that can't be easily scripted so we'll do this as a first step to reduce the Boost footprint. This also removes occurences of #include <boost/bind.hpp>, and makes sure all usages of std::bind have an #include <functional>. clang-format wasn't always applied to minimize the changeset in this commit, however, it was applied to the blocks of #includes. Due to conflicts with other Boost libraries, the placeholders _1, _2, etc. could not be directly used, but had to be explicitly called out (as std::placeholders::_1, etc.). This makes the use of std::bind even uglier, which serves as another reminder that using std::bind (and even more so, boost::bind) should be avoided. nirio/rpc/rpc_client.cpp still contains a reference to boost::bind. It was not possible to remove it by simply doing a search and replace, so it will be removed in a separate commit.
* examples: updating radio loopbackBrent Stapleton2019-11-262-113/+155
| | | | Modified to run with the new RFNoC API.
* examples: benchmark_rate: Remove usage of boost::posix_timeMartin Braun2019-11-261-18/+25
| | | | | Replace with std::chrono functions instead, in our effort to reduce Boost footprint.

* uhd: Replace boost::function with std::functionMartin Braun2019-11-261-1/+1
| | | | | | | This is mostly a search-and-replace operation, with few exceptions: - boost::function has a clear() method. In C++11, this is achieved by assigning nullptr to the std::function object. - The empty() method is replaced by std::function's bool() operator
* uhd: Replace BOOST_FOREACH(v, c) with for(v : c)Martin Braun2019-11-262-3/+2
| | | | | Also removes all references to boost/foreach.hpp. BOOST_FOREACH is no longer necessary since all headers require C++11 anyway.
* uhd: Replace usage of boost smart pointers with C++11 counterpartsMartin Braun2019-11-264-12/+12
| | | | | | | | | | | | | | | | | | | This removes the following Boost constructs: - boost::shared_ptr, boost::weak_ptr - boost::enable_shared_from_this - boost::static_pointer_cast, boost::dynamic_pointer_cast The appropriate includes were also removed. All C++11 versions of these require #include <memory>. Note that the stdlib and Boost versions have the exact same syntax, they only differ in the namespace (boost vs. std). The modifications were all done using sed, with the exception of boost::scoped_ptr, which was replaced by std::unique_ptr. References to boost::smart_ptr were also removed. boost::intrusive_ptr is not removed in this commit, since it does not have a 1:1 mapping to a C++11 construct.
* Remove proto-RFNoC filesMartin Braun2019-11-264-14/+5
| | | | | | | This commit removes all files and parts of files that are used by proto-RFNoC only. uhd: Fix include CMakeLists.txt, add missing files
* rfnoc: examples: Porting examples to new RFNoCBrent Stapleton2019-11-263-206/+203
| | | | | | | | | | | | | rfnoc_nullsource_ce_rx, rfnoc_rx_to_file: These examples are modified so they can be run with the new RFNoC API. test_messages: Fixes failures in the time test when it is executed immediately after an underrun test. The DUC considers time specs on a per burst basis, so when the underrun test leaves a burst unfinished, a time spec on the next burst is ignored.
* uhd: Remove deprecated objects and methodsMartin Braun2019-11-263-19/+1
| | | | | | | | | This removes the following symbols: - otw_type_t - clock_config_t - Any functions that use those symbols - Non-standard args from examples (e.g., --total-time is deprecated in favour of --duration)
* cmake: Bump dependency versions for UHD 4.0.0.0Martin Braun2019-11-261-2/+2
| | | | | | | | | | | | - Boost >= 1.58 - CMake >= 3.5.1 - gcc >= 5.4.0 - Clang >= 3.8, AppleClang >= 600 - Python >= 3.5 (Py2k no longer supported) - Numpy >= 1.11 - C++14 for lib, include may now use C++11 constructs. - Because there is no more code requiring C++03 syntax, we remove the include-specific clang-format file

* examples: test_pps_input: Also test for ref_locked on E31xMartin Braun2019-11-211-9/+26
| | | | | | | | | The E31x will always have a valid PPS, because it is generated internally. The external PPS however is used to drive the ppsloop, which means the ref_locked sensor can be a substitute for the PPS, but only on in this case. This commit also removes some superfluous includes from this example.
* examples: remove thread priority elevationCiro Nishiguchi2019-10-2226-62/+0
| | | | | | | Remove UHD call to elevate thread priority to realtime. Setting all threads to the same realtime priority can cause the threads to not share access to the network interface fairly, which adversely affects operation of the worker threads in UHD.
* cmake: Use new UHDBoost.cmake in init_usrp and toolsMichael Dickens2019-10-151-38/+22
| | | | | | | Modifies the CMake for the following utilities: - init_usrp (example) - kitchen_sink - nirio_programmer
* examples: Add mode to remove latency of RX samples in latency_testAlex Williams2019-10-071-3/+16
| | | | | | | | The timestamp from the streamer corresponds to the first sample, but a better indicator of transport latency will use the time of the last RX sample. Otherwise, nsamps will reduce the timing budget to send the TX samples. Include this mode to allow latency_test to have a version where there is largely no dependence amongst the variables.

| | | | | | | | - When printing statistics, the number of TX and RX timeouts were mixed up. - Fixing main() docstring Fixes e735a63ff9e ("python: Adding Python API benchmark rate")
* uhd: mpm: update all license header w/ "-or-later"Brent Stapleton2019-03-083-3/+3
| | | | Updating all SPDX license identifiers to include "-or-later"
* examples: tx_samples_c: Fix memory leakMoritz Fischer2019-02-151-2/+5
| | | | | | | | | Fix memory leak: 'buff' was never freed. While we're at it replace the kludgy malloc(n*y*sizeof(float)) by calloc(sizeof(float), n*y). Signed-off-by: Moritz Fischer <moritz.fischer@ettus.com>
* examples: benchmark_rate: Remove dead store to is_lockedMoritz Fischer2019-02-151-1/+0
| | | | | | | Remove dead store to is_locked. The variable isn't read before being overwritten, so the extra store is useless. Signed-off-by: Moritz Fischer <moritz.fischer@ettus.com>
* examples: Fix boundary condition in ascii_art_dft plottingMartin Braun2019-01-211-1/+1
| | | | | | There was a corner case where the data could be such that the FFT plot symbol selection would cause an out-of-bounds access on the symbols table, and abort the example with an uncaught exception.
* uhd: mpm: apply clang-format to all filesBrent Stapleton2019-01-1630-3081/+3517
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Applying formatting changes to all .cpp and .hpp files in the following directories: ``` find host/examples/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/tests/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/dboard/neon/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/dboard/magnesium/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/device3/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/mpmd/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/x300/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/utils/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find mpm/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file ``` Also formatted host/include/, except Cpp03 was used as a the language standard instead of Cpp11. ``` sed -i 's/ Cpp11/ Cpp03/g' .clang-format find host/include/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file ``` Formatting style was designated by the .clang-format file.
* ascii_art_dft: move example within include guardBrent Stapleton2019-01-161-2/+1
| | | | | Moving the example `main` within the include guards for the file. This is mostly to help clang-format's include guard detection.
* examples: utils: skip formatting program optionsBrent Stapleton2019-01-1627-0/+54
| | | | | | Turning off clang formatting around the program option declarations. clang-format makes them looks bad an unreadable because it thinks the options are function calls or something.
* examples: Improved error message in tx_waveformsDerek Kozel2019-01-141-2/+6

* examples: change boost to std for time commandsmguyler-ni2019-01-081-40/+58
| | | | | | - examples affected: rfnoc_rx_to_file - fixes UHD build error with Boost 1.67: boost::posix_time::seconds no longer supports double argument as of version 1.67
* examples: optimize tx_waveforms memory allocationsBrent Stapleton2019-01-031-5/+10
| | | | | | | Move filling the TX buffer outside the critical path. Now, we pre-fill the TX buffer before entering the send loop (and before setting the TX stream time), and fill the TX buffer after calling send() (for the next iteration).
* examples: formatting in tx_waveformsBrent Stapleton2019-01-031-2/+8
| | | | | - Format `if` statements to multiple lines - Add quick comment on the exit checks
* examples: optimize benchmark_rate start timeBrent Stapleton2019-01-031-3/+3
| | | | | | | | Move the setting of the streaming start times back as late as possible. Currently, there are memory allocations in between setting the time_spec in the TX metadata and actually starting streaming. This will lessen the need for an INIT_DELAY and decrease the probability of late packets.
* uhd: Add benchmark_streamer support for multi-channel streamerCiro Nishiguchi2018-12-171-275/+478
| | | | | | | | Add support for benchmarking multi-channel streamers. This also simplifies the way the test parameters are specified to avoid confusion due to the additional dimension. For rx, multi-channel streamer configurations require split_stream noc blocks so that timestamps of packets in the same streamer align. Add support for loopback FIFOs.
* examples: Add keyboard controls to rx_ascii_art_dftRakesh Peter2018-12-171-3/+116
| | | | | | | | | - Add keyboard controls for sample rate, gain, analog bandwidth, frequency, as well as the display's dynamic range, reference level, and frame rate. - The current values for these properties, as well as the keys to control them, are displayed in a small window at the top of the display. This control window can be toggled by pressing 'c'
