* cmake/doxygen: Fix FPGA manual post-FPGA-mergeMartin Braun2020-02-063-39/+7
| | | | | | | While merging the FPGA code into the UHD codebase, the manual building process was not modified, resulting in either a link to the website instead of building the FPGA manual as part of the rest, or by using a residual submodule.
* rfnoc: Provide make_args_t dtor in rfnoc_blocks_testAaron Rossetto2020-02-041-0/+3
|
* examples: benchmark_rate clean print outmattprost2020-02-041-8/+12
| | | | | | Cleans up the print out for the benchmark rate example. Removes race condition that would cause send and receive initialization messages to interleave to stdout.
* octoclock: Change type of EEPROM property to mboard_eeprom_tMartin Braun2020-02-043-6/+10
| | | | | | | | | Before, the type was octoclock_eeprom_t, which was incompatible with mboard_eeprom_t and would cause issues with uhd_usrp_probe. octoclock_eeprom_t is a superset of mboard_eeprom_t, and there is no necessity for exposing the additional features to the public. This harmonizes the Octoclock prop tree with the rest of UHD, and fixes an issue where the Octoclock won't allow uhd_usrp_probe on master branch.
* octoclock: Avoid usage of uninitialized memoryMartin Braun2020-02-045-41/+48
| | | | | | | | The Octoclock host code would send uninitialized memory over the network, which would be flagged by tools such as Valgrind. This patch creates a factory function for OctoClock packets that initializes the memory to zero, defaults the proto version to the OctoClock default, and can provide a random sequence number if none is given.
* octoclock: Apply clang-formatMartin Braun2020-02-048-659/+753
|
* multi_usrp: Add get_tree() API callMartin Braun2020-02-043-0/+14
| | | | | | This allows access to the underlying property tree without having to refer to the device object. Useful for RFNoC objects, where the device object is not accessible.
* docs: fix typo in stream.hppMichael Dickens2020-01-291-1/+1
|
* rfnoc: Create mock factoryMartin Braun2020-01-297-69/+135
| | | | | | This is an API that allows creating mock block controllers, to write unit tests for block controllers. See rfnoc_blocks_test for an example how to use them.
* log: Remove LOG statement from _get_log_level()Martin Braun2020-01-291-2/+1
| | | | | | _get_log_level() is an internal function that only gets called during setup, so the logger isn't ready yet. It thus now logs to stderr instead of the logger.
* utils: log: Name all threadsMartin Braun2020-01-291-5/+16
| | | | | | Logging creates two threads, one for regular logging, and one for fastpath logging. Now these threads are named using uhd::set_thread_name()
* thread: Remove log messages for set_thread_name() when not supportedMartin Braun2020-01-291-10/+14
| | | | | | | | | | | On systems like Windows, set_thread_name() is not supported, and would previously log an error message telling the user that it can't set the thread name. However, that prevents set_thread_name() to be called before the logger is being set up, and the logger would like to use this function. Since it is obvious to the user if threads can be named or not, the log message is considered redundant and is removed.
* rfnoc_device: Remove spurious commentMartin Braun2020-01-231-2/+1
| | | | | This removes a comment that refers to Boost smart pointers, which were removed in UHD.
* docs: e3xx/n3xx: Add sections on FP-GPIOs and how to drive themMartin Braun2020-01-232-0/+109
| | | | This gives examples of how to use the set_gpio_src() API and friends.
* multi_usrp: Amend APIs for GPIO source controlMartin Braun2020-01-233-13/+50
| | | | | | | | | | | This adds a new API call to multi_usrp: get_gpio_src_banks(). This returns a list of GPIO banks who's source can be controlled through the motherboard controller. The remaining GPIO source methods' docstrings are improved, to explain the difference between GPIO banks for set_gpio_attr() and set_gpio_src(). The former controls the actual value on a GPIO bank, and the latter who drives it. These can be different banks.
* mpm/mpmd: Expose APIs to drive GPIO sourcesMartin Braun2020-01-232-0/+48
| | | | | | | | | | | | | | | | | | | The N310 has a feature that allows the front panel GPIOs to be driven by various sources: The PS, or any of the radio channels. The MPM-based APIs did not expose any way to change that. Changes: - Add MPM APIs to PeripheralManagerBase and n3xx classes - Improve comments and explanations - Add host-side hooks into these new APIs in mpmd_mb_controller - Implement these APIs for N3xx The N3xx devices will have the option to set the GPIO source to "PS", or to one of "RF0", "RF1", "RF2", "RF3" (if there are four channels; the N300 and N320 can only go up to RF1). Note: The N310 radio does not have separate FP-GPIO banks for channels 0 and 1, which needs to be fixed in a separate commit.
* mpmd: Use dpdk_simple for MTU discoveryAlex Williams2020-01-221-91/+16
| | | | And delete the stale code for the DPDK-specific version.
* x300: Remove early x300_device_args usageAlex Williams2020-01-221-7/+6
| | | | | | | | Args were being parsed in x300_eth_manager::find(), before UHD could ascertain the args were intended for an X300 device (and not some other device). This caused unwarranted error messages to print in some cases. The changes here fix this and prevent the premature parsing and error messages.
* cmake: Find DPDK via pkg-config, if availableAlex Williams2020-01-226-29/+62
| | | | | | Debian uses pkg-config without the libdpdk.so linker script. Use the pkg-config file to grab the installed libraries and determine what to link to.
* transport: liberio: correctly release resources on destructionJoerg Hofrichter2020-01-221-6/+8
| | | | | | | | | | Stop the streaming and free the allocated buffers on destruction of the liberio xport object. Note: There is a lingering resource leak in the kernel module, this patch merely orders the resource release correctly. Signed-off-by: Joerg Hofrichter <joerg.hofrichter@ni.com>
* fixup! docs: e320: Add documentation for gpio and eeprom-flagsJoerg Hofrichter2020-01-221-2/+2
|
* docs: n3xx: document eeprom flagsJoerg Hofrichter2020-01-221-0/+34
| | | | | | | | Add a subsection to both N310- and N320 specific features to document the EEPROM flags simliar to as it is done in the E320 documentation. Signed-off-by: Joerg Hofrichter <joerg.hofrichter@ni.com>
* utils: images_downloader: adding usage docsBrent Stapleton2020-01-221-2/+29
| | | | | Adding more details on uhd_images_downloader usage, as well as some technical details.
* examples: Fix tx timeout caused by initial delayCiro Nishiguchi2020-01-201-3/+4
| | | | | | Using default values, the initial delay for tx is larger than the default timeout of tx_streamer::send. Changing the example to always specify a timeout in send.
* nirio: use `realpath` instead of `relpath`Michael Dickens2020-01-151-6/+6
| | | | | | | The latter causes issues with some builds using `/tmp` as the build directory. Ref: https://github.com/EttusResearch/uhddev/commit/9517de45709adaea8b574011573a565007149d5d This commit changed these from `abspath` to `relpath` for Windows needs. Trying `realpath` as an alternative to both of those.

* uhd: Correct rx/tx EEPROM typoToni Jones2020-01-071-5/+5
| | | | Correct a typo differentiating RX and TX EEPROM paths.
* python: rfnoc: finishing noc_block_base::get_mtuBrent Stapleton2020-01-062-0/+28
| | | | | | | Adding bindings for res_source_info, which allows us to use noc_block_base::get_mtu. Fixes: 400b00c34338 ("rfnoc: adding RFNoC Python API")
* python: rfnoc: make block_id_t more compatible with stringsBrent Stapleton2020-01-061-0/+3
| | | | | Allows the RFNoC Python API to automatically convert strings to block_id_t's.
* rfnoc: adding RFNoC Python APIBrent Stapleton2020-01-025-0/+273
| | | | | | | | Adding Python bindings for the RFNoC API. This includes the rfnoc_graph, noc_block_base, and several other supporting classes. Templated functions are not currently supported. For example, `rfnoc_graph::get_block` can only return the basic block controller.
* rfnoc: fix typosBrent Stapleton2020-01-021-2/+2
| | | | Fixes: 967be2a4e82b ("uhd: mpm: apply clang-format to all files")
* uhd: fix for exception due to use of unconstructed mutexPatrick Sisterhen2020-01-021-4/+5
| | | | | | In chdr_ctrl_endpoint recv_thread, _recv_thread was starting at construction time and trying to lock mutex, but due to member declaration in class, mutex was not yet constructed
* 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>
* multi_usrp: unify GPIO access typeBrent Stapleton2019-12-301-1/+1
| | | | | | | | GPIOs in the property tree are registered as uint32_t's, so the get_gpio_attr function should use that type as well. This resolves a property tree runtime_error when running the `gpio` example with a B2xx device.
* tests: fixup compiler warningBrent Stapleton2019-12-301-1/+1
| | | | Fixes cb40069b ("tests: Port polling-mode dpdk_test to new DPDK...")
* 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.
* dpdk: Change client to wait on member variableCiro Nishiguchi2019-12-201-8/+12
| | | | | | Waiting on queue status seems to not always work, the queue state seems to not be updated immediately after pushing an item onto it when queried from a different thread.
* usrp: Change default number of data frames for X300Ciro Nishiguchi2019-12-201-16/+20
| | | | | | Change the default number of frames so that it works well when using offload threads, including DPDK. This matches the default number of frames in mpmd.
* transport,usrp: Make available packet-based flow controlAlex Williams2019-12-207-46/+61
| | | | | | | | DPDK provides a fixed number of fixed-size buffers for the receive window, so it needs packet-based flow control to avoid dropping packets. This change enables counting by packets. Co-authored-by: Ciro Nishiguchi <ciro.nishiguchi@ni.com>
* tests: Port polling-mode dpdk_test to new DPDK frameworkAlex Williams2019-12-203-83/+121
| | | | | | The mock_send_transport and mock_recv_transport are used, which ends up with two layers of flow control. More work may be needed here for comparisons with the old data.
* rfnoc: Make chdr_ctrl_xport recv_io callbacks have symbolsAlex Williams2019-12-202-26/+50
| | | | This helps a little with debugging (for breakpoints).
* transport: Fix comment on recv_io_if::fc_callback_tAlex Williams2019-12-201-1/+1
| | | | It referenced the wrong function for releasing recv buffers.
* usrp: Add I/O service manager for DPDKCiro Nishiguchi2019-12-203-0/+93

* lib: Remove dpdk_zero_copy filesMartin Braun2019-12-2014-3420/+0
| | | | These were left here as a reference.
* x300,mpmd: Enable DPDKMartin Braun2019-12-2012-465/+216
| | | | | | | | | | | | | | x300: - Remove obsolete variables from x300_eth_mgr and X300 motherboard components - Added some documentation / comments - Use constrained device args in more places - Enables the use of use_dpdk=1 - Switches between regular (kernel-based) and DPDK UDP mpmd: - Merge link_if_ctrl for udp and dpdk_udp - Update cmake options
