* multi_usrp: Fix ALL_CHAN and ALL_MBOARDS API calls for Gen-3 devicesMartin Braun2020-03-311-105/+64
| | | | | | | | Most of the API calls that default an arg to ALL_CHANS or ALL_MBOARDS were in fact broken. This adds a macro to efficiently mux out API calls that take such wildcard arguments so we don't have to repeat the same loop all over the place, even for those API calls that already correctly implemented wildcards (for consistency).
* utils: uhd_usrp_probe: Output frontend infoMichael West2020-03-311-5/+13
| | | | | | Add output of frontend info for RFNoC devices. Signed-off-by: Michael West <michael.west@ettus.com>
* docs: Update Basic/LF dboard references to use new operating modemattprost2020-03-312-21/+31
| | | | | | | | | | | | | | | On the new RFNoC with UHD 4.0 architecture, Basic/LF dboards use a new operating paradigm. The streaming mode (real mode or complex) is determined by setting the antennas (to A/B or AB/BA respectively). Basic/LF RX dboards also support 2 frontends (0 and 1), and Basic/LF TX dboards support 1 frontend (0). This new behavior only applies to applicable RFNoC devices (currently X300/X310). All pre-RFNoC devices (i.e. USRP2/N200 and earlier) maintain legacy behavior. RFNoC with UHD 3.xx branches also maintains old behavior. Signed-off-by: mattprost <matt.prost@ni.com>
* examples: Change benchmark_rate default thread priorityAaron Rossetto2020-03-271-1/+1
| | | | | | | | | | | | | | | | | | This commit modifies the benchmark_rate example to use the operating system's default thread priority, instead of real-time thread priority, by default. UHD 4.0 includes a number of significant improvements to the streaming architecture that allow for best performance to be achieved without having to resort to elevating the process thread priority to real-time. Internal testing shows degraded streaming performance in common use cases (i.e. non-DPDK) when the process thread priority is set to real-time. It should be noted that applications which use DPDK may still experience better performance when the process thread priority is set to real-time. Users may continue to manually override the process thread priority in benchmark_rate using the --priority=high command-line option. The need to elevate the process thread priority will be application- and deployment-dependent.

* uhd: cal: Add database classMartin Braun2020-03-2612-0/+542
| | | | | | This class contains methods to store and retrieve data from the local calibration database. Note that in this case, the "database" is just a bunch of files on the local filesystem.
* uhd: paths: Add get_cal_data_path() API callMartin Braun2020-03-263-1/+25
| | | | This points to the location where cal data is stored.
* x300: lf/basic antenna API implementationmattprost2020-03-234-110/+234
| | | | | | | | | | | | | | | | This results in a change of operation for LF/Basic Boards on X300/X310 devices. The RX streaming mode will now be specified by the antenna rather than the subdev: (AB or BA for complex streaming, and A or B for real-mode streaming, with AB being the default antenna value). For real-mode streaming, data is collected as complex data with zeroed-out values in the quadrature domain. The subdevs for these boards have been changed to 0 and 1 for the RX channels, and 0 for the TX channel, in order to align with subdev specs of other RFNoC devices. Note: the old streaming mode paradigm is still in place for the N210.
* utils: uhd_images_downloader: use HTTPS instead of HTTP to avoid redirectMarcus Müller2020-03-201-1/+1
| | | | | | | | Since the webserver responding to requests at http://files.ettus.com replies with a redirect to the same URL, but using the https:// transport, this isn't only the safer thing we should be doing, anyways, but also the quicker, since it saves the user from one unnecessary redirect.
* uhd: math: Add linear_interp()Martin Braun2020-03-182-7/+30
| | | | This lets you linearly interpolate between two points.
* debian: Rename control file for libuhd to contain 4.0.0 versionMartin Braun2020-03-181-0/+0

* debian: Fixes to copyright fileMartin Braun2020-03-181-389/+385
| | | | | | - FindGit.cmake is no longer part of UHD, removed from copyright list - The file list includes FPGA code, which needs to be updated to point to fpga/ instead of fpga-src/
* cmake: Add CMakeRC module and ::rc namespaceMartin Braun2020-03-184-1/+665
| | | | | | | | | | | | | | | | | | | | | | | | | | This module allows to add binary files into UHD (e.g., for cal data storage) in a platform-independent way. The upstream CMakeRC.cmake is modified in the following way to allow linkage against a shared object: ```diff # Generate the actual static library. Each source file is just a single file # with a character array compiled in containing the contents of the # corresponding resource file. add_library(${name} STATIC ${libcpp}) set_property(TARGET ${name} PROPERTY CMRC_LIBDIR "${libdir}") set_property(TARGET ${name} PROPERTY CMRC_NAMESPACE "${ARG_NAMESPACE}") target_link_libraries(${name} PUBLIC cmrc::base) set_property(TARGET ${name} PROPERTY CMRC_IS_RESOURCE_LIBRARY TRUE) + set_property(TARGET ${name} PROPERTY POSITION_INDEPENDENT_CODE ON) ``` This forces the -fPIC flag for the static object that CMakeRC generates, allowing to link it into a shared object file. The version of CMakeRC used is: a7e355290, cloned from git@github.com:vector-of-bool/cmrc.git.
* lib: deps: Add FlatBuffers 1.11.0 header filesMartin Braun2020-03-1817-0/+9179
| | | | | | | | | | FlatBuffers is used to (de-)serialize calibration data. For most use cases, only a few headers are required, so we provide them with UHD instead of requiring all UHD users to install their own version of FlatBuffers. This adds the headers to host/lib/deps, and updates the Debian copyright file appropriately.
* lib: Use from_str<bool> in constrained_device_args_tAaron Rossetto2020-03-181-17/+7
| | | | | | | This modifies `constrained_device_args_t::bool_arg::parse()` to use `uhd::cast::from_str<bool>` to interpret strings as Boolean values, deduplicating the string parsing code and single-sourcing it from `uhd::cast`.
* utils: Add bool specialization to cast::from_str()Aaron Rossetto2020-03-183-0/+60
| | | | | | | This adds a specialization to `uhd::cast::from_str()` to handle `bool` as a target type and interpret strings like 'y', 'Y', 'n', 'No', 'True', 'False', etc. as Boolean values, as well as the traditional '0' and '1' (which also work).
* tests: Allow custom name for mock terminatorAaron Rossetto2020-03-131-4/+6
| | | | | | | Allow a unit test to instantiate a mock_terminator_t and provide a custom name to be displayed when get_unique_id() is called (generally for logging purposes). The custom name is optional and the generic 'MOCK_TERMINATOR' is used if unset.
* tests: Allow custom mock_reg_iface_t in mock blockAaron Rossetto2020-03-132-8/+10
| | | | | | Allow clients to pass a custom instance of a mock_reg_iface_t for use with mock_block_container. This is especially useful when a block test subclasses mock_reg_iface_t to implement specialized behaviors.
* utils: cal: Replace property tree accesses with other API callsMartin Braun2020-03-121-43/+35
| | | | | | | | | | The cal utils read the property tree to identify the daughterboard information (serial, type, etc.). The paths for properties have changed in UHD 4.0, causing these utilities to fail. Instead of conditionally parsing the property tree, this commit changes the utilities such that dictionaries are pulled out of the multi_usrp object, which work regardless of the device type.
* multi_usrp: Provide valid return value for multi_usrp::get_device()Martin Braun2020-03-123-8/+72
| | | | | | | | | | | | For RFNoC devices, multi_usrp::get_device() no longer returns a device pointer, rather, it returns a nullptr. This is intentional because access to the underlying device is no longer allowed. However, legacy code can segfault (e.g. portions ofr gr-uhd). This patch returns a faux uhd::device class, which almost mimicks the original behaviour perfectly, by redirecting its class methods back to multi_usrp_rfnoc. The only exception is recv_async_msg(), which requires a TX streamer. This function will always return false now.
* utils/C API: Fix property tree accessMartin Braun2020-03-123-8/+8
| | | | | | | | | | The introduction of multi_usrp_rfnoc caused multi_usrp::get_device()->get_tree() to segfault for gen3 devices. In defcb174, we introduced a fix for this (multi_usrp::get_tree()) but we didn't apply it to internal utilities. That means the uhd_cal_* utilties were broken, along with certain sections of the C API, and the latency test suite. This fixes the segfault issue.
* python: Export UHD paths utility functionsMartin Braun2020-03-123-0/+30
| | | | | | | | | All of the functions defined in uhd/utils/paths.hpp are now available in Python, with the exception of get_module_paths(). #!/usr/bin/env python3 import uhd print(uhd.get_lib_path()) # Prints location of libuhd
* python: Remove Python2-specific codeMartin Braun2020-03-121-7/+0

* lib: gain_group: Remove spurious logsMartin Braun2020-03-121-2/+0
| | | | | | Whenever gains where set through a gain_group, it would output spurious log messages that must stem from someone's debug code, since the log messages are not very useful by themselves.
* python: Arrange file in Python module into uhd/ subdirectoryMartin Braun2020-03-108-21/+54
| | | | | | | | | | | | | | | This adds the host/python/uhd subdirectory, which will add all files that go into the actual Python module once installed. Before, all Python files were directly in host/python and got sorted into their appropriate destination folders during configuration and installation. This change doesn't change anything (Python modules will look the same as they do now), except that it makes the source tree a tad neater, but more importantly, it creates a consistent directory structure when adding submodules to the uhd module. Apart from the PyBind11-generated shared object file (which gets generated during build time), the uhd/ subdirectory in host/python exactly resembles the Python module once installed, so it's more obvious where to add new submodules and files.

* sim: Parameterize chdr_word_t data typeWade Fife2020-03-092-2/+12
| | | | | | | | | | | | | | | | | | This replaces chdr_word_t, which was a statically defined 64-bit data type, with a paramaterizable data type that matches the defined CHDR_W. Code that formerly referenced the chdr_word_t data type can now define the data type for their desired CHDR_W and ITEM_W as follows: // Define the CHDR word and item/sample data types typedef ChdrData #(CHDR_W, ITEM_W)::chdr_word_t chdr_word_t; typedef ChdrData #(CHDR_W, ITEM_W)::item_t item_t; ITEM_W is optional when defining chdr_word_t if items are not needed. Static methods in the ChdrData class also provide the ability to convert between CHDR words and data items. For example: // Convert CHDR data buffer to a buffer of samples samples = ChdrData#(CHDR_W, ITEM_W)::chdr_to_item(data);
* uhd: Apply clang-format against all .cpp and .hpp files in host/Martin Braun2020-03-03432-22914/+24827
| | | | | Note: template_lvbitx.{cpp,hpp} need to be excluded from the list of files that clang-format gets applied against.
* docs: n3xx/x3xx: Fix links to DPDK pagesteviez2020-02-272-2/+2
| | | | | | | The n3xx and x3xx device pages both link to the DPDK page. However, the link was setup as type "subpage" instead of "ref". The result was that both device pages thought they owned the DPDK page which caused non-intuitive behavior when clicking through links in the manual

* rfnoc: Reuse the graph objectAndrew Lynch2020-02-261-1/+20
| | | | | Keep a reference to the graph object so that when a new multi_usrp is opened to the same device, the same graph is also used.

* examples: Wrap get_gpio_src() with try/catch blocksteviez2020-02-191-7/+14
| | | | | Non-RFNoC devices do not support get_gpio_src() entrypoing so wrap call with a try/catch block
* utils: images downloader: Add support for UHD_IMAGES_URL, clean upMartin Braun2020-02-191-35/+29
| | | | | | - Remove Python2 compat hacks - Read the UHD_IMAGES_URL environment variable. If set, it overrides the default value for --base-url
* utils: images downloader: Handle missing content-length responseMartin Braun2020-02-191-7/+18
| | | | | | If the content-length header is not available, uhd_images_downloader will now ask the user if she wants to continue. Previously, the tool would throw an exception.
* rfnoc: actions: Cleanup rx_event_action_info ctorsteviez2020-02-183-13/+18
| | | | | Set error code member variable in rx_event_action_info constructor instead of relying on the caller to set it after object creation
* rfnoc: actions: Fix uninitialized timestampssteviez2020-02-183-11/+18
| | | | | | tx_event_action_info objects were being created with uninitialized timestamp members which led to uhd::tx_streamer::recv_async_msg() returning with invalid timestamps
* utils: image_downloader: check write conditionssteviez2020-02-181-0/+13
| | | | | | | | | | Prior to downloading any images, check that the images destination: - Is a valid directory - Has valid permissions for images to be written Images are downloaded to a temporary location before being written to image destination, so these checks help avoid situation where images are downloaded but unable to be written
* x300: add front-panel GPIO source controleklai2020-02-186-47/+164
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a ZPU register to control the FP GPIO source. These are 2bits per GPIO pin, totalling 24 bits. 0 corresponds to RF-A, 1 corresponds to RF-B. The following Python code will control the upper 6 bits of the front-panel GPIO from the B-side radio on an X300: >>> import uhd >>> U = uhd.usrp.MultiUSRP("type=x300") >>> U.get_gpio_src_banks() ['FP0'] >>> U.get_gpio_src("FP0") ['RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA'] >>> U.set_gpio_src("FP0", ['RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFB', 'RFB', 'RFB', 'RFB', 'RFB', 'RFB']) >>> U.get_gpio_src("FP0") ['RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFA', 'RFB', 'RFB', 'RFB', 'RFB', 'RFB', 'RFB'] >>> # Make all GPIOs outputs: >>> U.set_gpio_attr("FP0A", "DDR", 0xFFF) >>> U.set_gpio_attr("FP0B", "DDR", 0xFFF) >>> # Control all GPIOs from software (not ATR): >>> U.set_gpio_attr("FP0A", "CTRL", 0x000) >>> U.set_gpio_attr("FP0B", "CTRL", 0x000) >>> # Bottom 3 pins go high from radio A >>> U.set_gpio_attr("FP0A", "OUT", 0x007) >>> # Top 3 pins go high from radio B >>> U.set_gpio_attr("FP0B", "OUT", 0xE00) Amends the gpio.cpp example to allow switching the source.

| | | | | - Apply clang-format - Remove unnecessary boost::format
* lib: utils: Don't use hard-coded path constantsRyan Volz2020-02-072-2/+27
| | | | | | | | | | | | | This replaces the package path constant with a runtime library path lookup. The package path is taken to be the parent directory of the library directory. When boost >= 1.61 is not available, this maintains the current behavior of using CMake to set path contants. Runtime path determination is preferable for making a relocatable library so that it is not necessary to do string substitution on relocated binaries (as with, for example, building a conda package).
* python: Set python module suffix to conform with PEP 3149.Ryan Volz2020-02-071-1/+10
| | | | | | | | | This adds the python implementation, major and minor version numbers, and any additional flags (debug, pymalloc, wide unicode) to the extension module suffix as specified in PEP 3149. Hat tip to @isuruf: https://github.com/conda-forge/staged-recipes/pull/10076#discussion_r348721448
* python: Do not link against python lib for building an extension module.Ryan Volz2020-02-071-1/+10
| | | | | | | | | | | | This fixes a segmentation fault when trying to use the python module on OSX when built with conda (unsure why it doesn't arise otherwise). Instead of linking against the python library, it is proper to not link against the library and, for OSX builds, add linker options for "-undefined" and "dynamic_lookup". This is precisely what the CMake FindPython module does for linking against the Python::Module target. See https://blog.tim-smith.us/2015/09/python-extension-modules-os-x and https://bugs.python.org/issue36721
* python: Fix internal library name (incl. suffix) to match filename.Ryan Volz2020-02-071-7/+7
| | | | | | Instead of renaming the library file, this sets the suffix in CMake so that the filename turns out as desired and also linker references know the correct name.
* rfnoc: ddc: Make scaling optional, prefer to change decimMartin Braun2020-02-071-28/+53
| | | | | | | | | | | This combines two intertwined changes: - The scaling_in and scaling_out properties of the DDC now start off uninitialized. This is to avoid invalid loops of property resolution: When the block is first initialized in a graph context, the default values for scaling over-constrain the resolution problem. - The resolver for samp_rate_in used to prefer changing samp_rate_out, it now prefers to modify the decimation. This is necessary to allow calling set_output_rate() before the graph is committed.
