* dpdk: Add new DPDK stack to integrate with I/O servicesAlex Williams2019-12-2018-352/+2633
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | docs: Update DPDK docs with new parameters: Parameter names have had their hyphens changed to underscores, and the I/O CPU argument is now named after the lcores and reflects the naming used by DPDK. transport: Add new udp_dpdk_link, based atop the new APIs: This link is tightly coupled with the DPDK I/O service. The link class carries all the address information to communicate with the other host, and it can send packets directly through the DPDK NIC ports. However, for receiving packets, the I/O service must pull the packets from the DMA queue and attach them to the appropriate link object. The link object merely formats the frame_buff object underneath, which is embedded in the rte_mbuf container. For get_recv_buff, the link will pull buffers only from its internal queue (the one filled by the I/O service). transport: Add DPDK-specific I/O service: The I/O service is split into two parts, the user threads and the I/O worker threads. The user threads submit requests through various appropriate queues, and the I/O threads perform all the I/O on their behalf. This includes routing UDP packets to the correct receiver and getting the MAC address of a destination (by performing the ARP request and handling the ARP replies). The DPDK context stores I/O services. The context spawns all I/O services on init(), and I/O services can be fetched from the dpdk_ctx object by using a port ID. I/O service clients: The clients have two lockless ring buffers. One is to get a buffer from the I/O service; the other is to release a buffer back to the I/O service. Threads sleeping on buffer I/O are kept in a separate list from the service queue and are processed in the course of doing RX or TX. The list nodes are embedded in the dpdk_io_if, and the head of the list is on the dpdk_io_service. The I/O service will transfer the embedded wait_req to the list if it cannot acquire the mutex to complete the condition for waking.

* transport: Fix uninitialized offload I/O service _client_typeAlex Williams2019-12-201-5/+2
| | | | | | The client type is kept in _offload_thread_params, but a separate, unitialized field is checked in member functions. Remove the duplicate and switch the checks over. This fixes offload_io_srv_test.
* tests: Add more tests for max rate streamingCiro Nishiguchi2019-12-184-89/+469
| | | | | Add more tests to compare streaming rates with previous releases. Changed the output string to a table.

|
* tests: Add script to execute batch of benchmark_rate runsCiro Nishiguchi2019-12-065-0/+424
| | | | | Script runs benchmark_rate repeatedly, parses results, and calculates average, min, and max of each value reported.
* utils: algorithm: Add missing include uhd/config.hppMartin Braun2019-12-051-0/+1

* ddc: fixup decimation propertyBrent Stapleton2019-12-051-2/+2
| | | | | | | | - Use coerce_decim(), not int(), to coerce the decimation rate - Fix typo Fixes: a36fc4604f9b ("rfnoc: DDC: Fix property propagation") Fixes: 36853315741a ("rfnoc: Add DDC block controller")
* prefs: Set init_done flag to true after loading config filesMartin Braun2019-12-051-0/+1
| | | | | | | The prefs API is supposed to load the config files once, and stash them away for the process to consume at will. Because the init_done is never set, it will read the config files every time it's asked for them. This is usually not a problem, but it causes the logging output to be messy.

* e31x: Fix filter bank and antenna switching for channel 0Sugandha Gupta2019-12-023-43/+60
| | | | | | The filter bank and antenna switches have different configuration for channel 0 and channel 1. This commit fixes the issue where channel 0 produces only noise due to incorrect switches.
* rfnoc: DDC/DUC: Fix fp-issues with samp_rate propertiesBrent Stapleton2019-11-272-6/+67
| | | | | | Only update DDC/DUC samp_rate properties if the number is substantially different (don't update for sub-1Hz property calculations). This fixes resolver exceptions for certain rates.

* utils: tasks: Use uhd::set_thread_name()Martin Braun2019-11-261-3/+1
| | | | | This is a more portable option to set thread names. References to pthreads are now limited to thread.cpp, where they belong.
* mpmd: Name the claimer task threadMartin Braun2019-11-261-13/+15
| | | | | We call set_thread_name() on the claimer loop so the thread can be identified using OS utilities.

* rfnoc: fix incorrect long fifo wait timeoutsVirendra Kakade2019-11-261-2/+2
| | | | | | | This fixes behavior where we would get long 100 sec timeouts on fifo waits instead of 100 ms timeouts. Signed-off-by: Virendra Kakade <virendra.kakade@ni.com>
* mg: Turn the set-lock into a recursive mutexMartin Braun2019-11-262-15/+15
| | | | | Individual API calls might have to call each other (e.g., like set_rate() will call set_rx_frequency()), which would cause a deadlock.
* mg: Always set MCR on both daughterboardsMartin Braun2019-11-263-12/+33
| | | | | | | | | | | | | | | | | The N310 cannot set the MCR for its daughterboards separately. This patch modifies the radio block controller such that any block controller, when requested to change the master clock rate, will first change Radio 0, and then Radio 1. This fixes the following issues: - In multi_usrp, calling set_master_clock_rate() will not necessarily call set_rate() on the radios in any particular order, which will break when calling Radio 1 first - In RFNoC apps, it wasn't possible to run off of slot B alone without this change. Note: When calling set_rate() on one radio, the other radio is in an invalid state until its set_rate() is also called.
* lib: Add DPDK service queueAlex Williams2019-11-262-0/+302
| | | | | | | This is a data structure intended for use by the DPDK I/O service. It uses DPDK's lockless ring in multi-producer, single-consumer mode to allow clients to submit requests to the DPDK I/O service's worker thread. Clients can specify a timeout for the requests to be fulfilled.
* rfnoc: fix invalid access when sending packet with no samplesCiro Nishiguchi2019-11-261-1/+3

* mpmd: Fix get_mboard_name()Martin Braun2019-11-261-1/+1
| | | | | It used to produce the individual name of the USRP, but it should return a product name.
* rfnoc: Fix RAM port direction in YAMLWade Fife2019-11-269-98/+98

* 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
* n310: Fix GPIO registersMartin Braun2019-11-261-3/+6
| | | | | This enables the use of the dboard and FP GPIOs. The problem was that the register offset of 8 was not encoded.
* mg/rh/rfnoc: Harmonize peripheral registersMartin Braun2019-11-264-21/+29
| | | | | - Move the SPI addresses out of radio_control_impl - Fix the GPIO address spaces for N310/N300
* gpio_atr_3000: Fix return value for pin control registerMartin Braun2019-11-261-1/+3
| | | | | | | | | | | | | | | This fixes a bug where get_gpio_attr(bank, "CTRL") would return the inverted value of what was written. Reason is that the underlying register was an ATR disable register. The fix is to invert the cached values of the register. Now, the following Python code will work: >>> U = uhd.usrp.MultiUSRP("type=x300") >>> atr_enable = 0xF # Enable ATR on lower 4 pins, rest is GPIO >>> U.set_gpio_attr("FP0A", "CTRL", atr_enable) >>> U.get_gpio_attr("FP0A", "CTRL") == atr_enable True
* 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 ...]
* detail::graph: Add shutdown capabilityMartin Braun2019-11-263-14/+35
| | | | | | | | | | | | In the existing graph, when the shutdown was simply a release. However, any outstanding actions would trigger warnings (because released graphs aren't supposed to still have actions being passed around), which would sometimes be visible at the end of an application. This is a safer solution than simply releasing, because it explicitly sets a shutdown flag that all graph-affecting functions (property propagation and action handling) respect. Once the flag is set, the graph can no longer be booted up again.
* 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.
* devtest: Add test_messages_test to X310Martin Braun2019-11-263-12/+14
| | | | | | - Fixes issues with test_messages_test (it had inverted the pass/fail condition) - Improve Pylint scores in affected files
* devtest: Use with() statement to open filesMartin Braun2019-11-261-5/+9
| | | | | | | | | | | | | | This fixes warnings such as this during devtest: /home/mbr0wn/src/uhddev/host/tests/devtest/uhd_test_base.py:112: ResourceWarning: unclosed file <_io.TextIOWrapper name='./results_x300_F457AD.log' mode='r' encoding='UTF-8'> self.results = yaml.safe_load(open(self.results_file).read()) or {} /path/to/uhd/host/tests/devtest/uhd_test_base.py:150: ResourceWarning: unclosed file <_io.TextIOWrapper name='./results_x300_F457AD.log' mode='w' encoding='UTF-8'> yaml.dump(self.results, default_flow_style=False)) ok
* 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.
* e310: Fix issues in MPM and UHDMartin Braun2019-11-261-7/+3
| | | | | | | | | | | - Remove superfluous INFO logging - Improve formatting in many places - Improve Pylint score in various places - Add tear_down to DB object - Simplify custom EEPROM code for E310 - Fix time source selection code - Remove references to GPS_CTRL and GPS_STATUS (are E320 only) - Move clock source control out of MboardRegs object
* mpm/mpmd: Remove token requirement for device infoMartin Braun2019-11-261-2/+2
| | | | | This removes the token requirement for get_proto_ver() and get_chdr_width().
