* docs: DPDK Linux kernel underruns solutionmattprost2022-07-201-5/+21
| | | | | | | | | Previously we had documented a known issue involving the Linux kernel, which was causing a streaming performance regression. This resulted in periodic underruns. We now know what is causing the regression. Document the procedure to restore the original behavior. Signed-off-by: mattprost <matt.prost@ni.com>
* rfnoc: Fix warnings in replay_block_controlMartin Braun2022-07-201-3/+4
| | | | | | | - Missing override statements - Rephrase logical statement when reading command FIFO space. The statement was correct, but Clang12 issues a warning because it considers the choice of syntax error-prone.
* usrp2: Remove unused code segmentsMartin Braun2022-07-201-6/+0
| | | | This fixes compiler warnings under Clang12.
* uhd: refactor get_all_addrs to remove duplicatesSteven Koo2022-07-201-8/+17
| | | | | | | | | | This commit refactors the existing register definitions, so that duplicate entries don't get added to the get_all_addrs method. Duplicates caused long builds on macOS/Clang, where build times would go from sub 5 min to 50 min or more likely because of the compiler trying to optimize.

* examples: gpio: output before end of streammattprost2022-07-201-1/+1
| | | | | | | | The gpio values should be output before the stream ends. This matches the behavior of other tests in this file and prevents strange logs for passing tests. Signed-off-by: mattprost <matt.prost@ni.com>
* x300: Fix invalid GPIO source bank error messageAaron Rossetto2022-07-201-2/+2
| | | | | | | | | | | | | | | When calling `get_gpio_srcs()` or `get_gpio_src()` with an invalid bank parameter, the error text associated with the `uhd::runtime_error` that is thrown prints the expected bank, not the erroneous bank, e.g.: >>> my_x310.get_gpio_srcs('BAD_BANK', 0) [ERROR] [X300::MB_CTRL] Invalid GPIO source bank: BAD_BANK. Only supported bank is FP0 Traceback (most recent call last): File "<stdin>", line 2, in <module> RuntimeError: RuntimeError: Invalid GPIO source bank: FP0 The invalid source bank on the last line should read BAD_BANK, not FP0.

* ci: Fix mgmt_addr=None entry for X310 DPDK caseSteven Koo2022-06-101-1/+7
| | | | | | | | X310 differs from X410 in that it doesn't require the mgmt_addr to function. This does a check to see if the field has been added, instead of assuming that it has a value. Signed-off-by: Steven Koo <steven.koo@ni.com>
* Revert "tests: streaming: temporarily mark b210 dropped samples as an xfail"Steven Koo2022-06-101-12/+4
| | | | This reverts commit 50bda84c75c2087caebc2bfd5f8e8cd64b41e739.
* ci: Add recv and send frame tuning for streamingSteven Koo2022-06-102-1/+26
| | | | | | | | This adds the ability to tune the recv and send frames as a parameter. This is useful since some rates will fail with jitter in the system with the default settings. Signed-off-by: Steven Koo <steven.koo@ni.com>
* ci: set benchmark rate priority to highSteven Koo2022-06-101-0/+1
| | | | | | | | This change increases the benchmark rate priority to high, which reduces the jitter. This prevents UI interactions from causing overruns and underruns. Signed-off-by: Steven Koo <steven.koo@ni.com>

* tests: Remove packet_handler_benchmarkMartin Braun2022-06-102-380/+0
| | | | | | This was a test written in the early stages of re-writing UHD for the 4.0 release. It tests things that are no longer in use for UHD 4, thus, the test can go as well.
* zbx: Remove stray includeMartin Braun2022-06-101-1/+0
|
* utils: Remove usrp_e3x0_network_modeMartin Braun2022-06-101-72/+0
| | | | | | This was removed from CMake ages ago, and hasn't been built in years. It also no longer compiles. And since we do MPM on E310, it is also completely pointless.
* fixup! examples: gpio: Refactor exampleMartin Braun2022-06-101-14/+32
| | | | | | The example refactoring required usage of the get/set source API, which isn't available on B2xx series. This patch tests for the existence of said API, and disables its usage if appropriate.
* fixup! examples: gpio: Refactor exampleMartin Braun2022-06-101-4/+13
| | | | | | | | | | The refactoring changed the behaviour of --bitbang: before, it would terminate after one readback unless --repeat was specified, in which case it would require a Ctrl-C (SIGINT). After the refactoring, it always required a SIGINT. This changes the behaviour back to prior to 727141d, and will now only read back once, unless --repeat is provided. This also fixes the bitbang devtest, which would go on indefinitely.
* rfnoc: Add atomic_item_size property to FFT blockMartin Braun2022-06-102-1/+41
| | | | | | The atomic item size for the FFT block is always equal to the length of the FFT, multiplied by bytes-per-sample (4). For now, this is all the FFT block supports.
* examples: gpio: Refactor exampleMartin Braun2022-06-101-286/+368
| | | | | | | | | | | | | | | | The example had organically grown and was getting hard to read, and also had some known issues. Summary of fixes: - Default GPIO bank and connector are now derived from the device. This allows this example to pass without throwing an exception on E3xx and X4xx series when using default arguments. - The bitbang test is moved into its own code section, to make the rest more readable. - We move all the streamer-related code into a helper struct - Some repetitive parts of the code are moved into their own functions - The argument --require-loopback is added, which will fail tests if GPIO pins are not correctly looped back externally - --list-banks is renamed to --list_banks for consistency
* x300: Change order of GPIO banksMartin Braun2022-06-101-1/+1
| | | | | FP0 is now listed first. This helps with determining a default GPIO bank.
* tests: streaming: temporarily mark b210 dropped samples as an xfailMatthew Crymble2022-06-101-4/+12
|
* tests: streaming: use assert instead of pytest.fail for underruns/overrunsMatthew Crymble2022-06-101-2/+2
| | | | | | | When an assert statement fails, pytest will determine whether that should be a fail or an xfail. By explicitly calling pytest.fail, we were preventing pytest from doing that determination, so an individual test case that had an xfail mark would have been a hard failure.
* rfnoc: Fix vector use in replay_block_control_implAaron Rossetto2022-06-101-2/+2
| | | | | | | | | | | | | This commit fixes an issue in `replay_block_control_impl` with the initialization of the `_cmd_fifo_spaces` vector member variable. `std::vector<>::reserve()` only allocates memory for the vector items; it does not resize the vector (i.e., instantiating an `std::vector<>` and then calling `reserve()` leaves it with a size of 0). Attempting to index a zero-sized vector causes some C++ debug mode runtimes to throw an index out-of-range exception. The commit instantiates the vector using the constructor variant that allocates memory sufficient for the entries and default initializes them so that it can be indexed without issue.
* rfnoc: Fix register_xport_hop_cfg_fns() usageMartin Braun2022-06-102-4/+11
| | | | | | Note: This function is currently unused. However, it is not correctly implemented. During init, it would call the routing configuration function instead of the init configuration function.
* rfnoc: Improve comments regarding streaming and mgmt. codeMartin Braun2022-06-108-13/+74
| | | | | This commit *only* touches comments in the code for RFNoC streaming, link management and management portal.

* tests: streaming: add support for B210 DUTsMatthew Crymble2022-06-101-2/+7
| | | | | | The use_dpdk will be false for all B210 test cases, but still needs to be defined since the main test_streaming() function requires a value for it.
* tests: streaming: include dual_SFP parameter for all casesMatthew Crymble2022-06-101-20/+18
| | | | | | The dual_SFP test case parameter will be false for all B210 and E320 test cases, but it still needs to be defined since the main test_streaming() function requires a value for it.
* tests: streaming: add support for more DUTsMatthew Crymble2022-06-101-0/+4
| | | | | | | | | | This commit enables runs for X310, X310 TwinRx, E320, and N310. By default, python's argparse module will expect a value to be provided for each argument defined. Specifying an nargs value of '?' for the pytest options allows us to use a single pytest invocation in our pipeline configuration, even though some options don't apply to some DUT types.
* n320: Fix reading DB serial in applying correctionsMartin Braun2022-06-101-2/+2
| | | | | | The frontend corrections for N320 (IQ imbalance, DC offset) require the DB serial. However, there was an error in reading the DB serial in the code that applies the corrections.
* rfnoc: fix double conversionsLars Amsel2022-06-101-4/+3
| | | | | result of get double was saved in an int value instead of double replaced C cast by static_cast
* n320: Improve comments regarding low bandMartin Braun2022-06-102-4/+6
| | | | | The N320 code include some constants that were either unused or incorrect. This clarifies the lowband frequency.
* fpga: rfnoc: Remove rfnoc_version from target YAMLWade Fife2022-06-101-1/+0
| | | | | | This causes the latest RFNoC protocol version to be used by default and avoids the need to update YAML files every time the RFNoC protocol version gets bumped.

* utils: uhd_images_downloader: Increase default image download size limitmattprost2022-06-101-5/+4
| | | | | | | | | | Prompt users for download confirmation of files larger than 1 GiB instead of 100 MiB. Improve messaging to make this process less concerning for users. The defined limit is only for the user's convenience. A 1 GiB limit should allow users to download most uhd images and related files without being prompted.

* uhd: change default into option flag in register definitionLars Amsel2022-06-103-35/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for read only registers in generated interfaces. For this the default is extended to an option string. The old format is still supported for backward compability, so if options string is just a number it will be handled as a writable number. The option string is a comma separated list with key=value pairs. The value is optional and treated as None if missing. common.py now allows to pass in **kwargs to the generate method which is used by gen_zbx_cpld_regs.py to pass a filter function for registers used by mpm only. get_all_addr now has an additional (optional, defaults to false) flag to indicate whether read only addresses are to be returned or not. It also supports type generic for the result to align with get_changed_addr function. The ZBX CPLD CTRL map is adapted accordingly to reflect read only registers. The power registers are flagged as MPM scope only (and not used in ZBX CPLD control of UHD). Co-authored-by: Martin Braun <martin.braun@ettus.com>
* cmake: Add support for fedora rpm versioningmattprost2022-06-103-16/+24
| | | | | | | | | Adds cmake option for replacing dashes in the UHD Component version with underscores. This is necessary as Fedora package management is now enforcing the format <Package>-<Version>-<Release> for all rpm builds, so dashes in the UHD_VERSION from dev branches is not supported. Signed-off-by: mattprost <matt.prost@ni.com>
* n310: Improve LO source control options for ALL and LO2 casesmattprost2022-06-101-19/+40
| | | | | | | | If ALL option is specified, set lo source for both lo's. Do not report an error if user sets LO2 to internal. Enforce single lo target for queries about lo state. Signed-off-by: mattprost <matt.prost@ni.com>
* cmake: Drop .deb generation via cpack in favour of better toolsMartin Braun2022-06-101-49/+18
| | | | | | Building .deb files has an entire ecosystem dedicated to it which is superior to cpack, and we don't test cpack, either. Users wanting to build .deb files should take a look at tools/debs/uhd_ubuntu_deb.py.
* utils: uhd_images_downloader: Print name of file that exceeds limitWade Fife2022-06-101-5/+5
| | | | | When a file exceeds the download limit, print the name of the file in the message that asks if we want to continue downloading.
