* rfnoc: Fix block buffer sizes referring to MTUWade Fife2022-03-048-17/+23
| | | | | | | In the HDL, the parameter named 'MTU' is clog2 of the size of the desired MTU. For example, when the 'MTU' parameter is 10, that means the actual MTU setting is 2**MTU or 1024. So we need to set our buffers to 2**MTU if we want them to be one MTU in size.

* rfnoc: Refactor ctrlport_endpoint; fix MT issuesAaron Rossetto2022-03-031-121/+170
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit refactors ctrlport_endpoint and fixes several issues related to multiple threads sending and receiving control transfers. First, it refactors the change that Martin Braun implemented in 0caed5529 by adding a tracking mechanism for control requests where clients have explicitly asked to receive an ACK when the corresponding control response is received. When a client wants to wait for an ACK associated with a control request, a combination of that request's opcode, address, and sequence number is added to a set when the request is sent. When a control response is received, the set is consulted to see if the corresponding request is there by matching the packet field data listed above. If so, the control response is added to the response queue, thus notifying all threads waiting in `wait_for_ack()` that there is a response that the thread may be waiting on. If the request is not in the set, the request is never added to the response queue. This prevents the initial problem that 0caed5529 was addressing of the response queue growing infinitely large with control responses that would never be popped from the queue. Secondly, it addresses issues when multiple threads have sent a request packet and are waiting in `wait_for_ack()` on the corresponding response. Originally, the function contained a loop which would sleep the calling thread until the control response queue had at least one element in it. When awakened, the thread would pop the frontmost control response off the queue to see if it matches the corresponding control request (i.e., has the same sequence number, opcode, and address elements). If so, the response would be handled appropriately, which may include signalling an error if the response indicates an exceptional status, and the function would return. If the response is not a matching one, the function would return to the top of the loop. If the corresponding response is not found within a specified period, the function would throw an op_timeout exception. However, there is a subtle issue with this algorithm when two different calling threads submit control requests and end up calling `wait_for_ack()` nearly simultaneously. Consider two threads issuing a control request. Thread T1 issues a request with sequence number 1 and thread T2 issues a request with sequence number 2. The two threads then call `wait_for_ack()`. Let's assume that neither of the control reponses have arrived yet. Both threads sleep, waiting to be notified of a response. Now the response for sequence number 1 arrives and is pushed to the front the response queue. This generates a signal that awakes one of the waiting threads, but which one is awakened is completely at the mercy of the scheduler. If T1 is awakened first, it pops the response from the queue, finds that it matches the request, and handles it as expected. Later, when the reponse for sequence number 2 is pushed onto the queue, the still-sleeping T2 will be awakened. It pops the response, finds it to be matching, and all is well. But if the scheduler decides to wake T2 first, T2 ends up popping the response with sequence number 1 off the front of the queue, but it doesn't match the request that T2 sent with sequence number 2, so T2 goes back to the top of the loop. At this point, it doesn't matter if T2 or T1 is awakened next; because the control response for sequence number 1 was already popped off the queue, T1 never sees the control response it expects, and will throw uhd::op_timeout back up the stack. This commit modifies the `wait_for_ack()` algorithm to search the queue for a matching response rather than indiscriminately popping the frontmost element from the queue and throwing it away if it doesn't match. That way, the order in which threads are awakened no longer matters as they will be able to find the corresponding response regardless. Furthermore, when a response is pushed onto the response queue, all waiting threads are notified of the condition via `notify_all()`, rather than just waking one thread at random (`notify_one()`). This gives all waiting threads the opportunity to check the queue for a response. Finally, the `wait_for_ack()` loop has been modified such that the thread waits to be signalled regardless of whether the queue has elements in it or not. (Prior to this change, the thread would only wait to be signalled if the queue was empty.) This effectively implements the behavior that all threads are awakened when a new control response is pushed into the queue, and combined with the changes above, ensures that all threads get a chance to react and check the queue when the queue is modified.
* mpm: fix ref_locked sensor on n320David Raeman2022-03-031-0/+15
| | | | | | | | | | | | | | | | The ref_locked mboard sensor on the n320 always returned true without querying hardware. On this device family, mboard sensor callback in n3xx.py returns the "and" of its daughterboard LMK PLLs by querying the get_ref_lock() function on each dboard manager. However, that function only existed for the Magnesium daughterbaord. For the Rhodium daughterboard, the function didn't exist and so a true value was automatically returned. This commit adds the get_ref_lock() implementations for Rhodium and EISCAT daughterboards, which are identical to the implementation already present for Magnesium.

* examples: replay: Improve rfnoc_replay_samples_from_fileMartin Braun2022-03-021-127/+87
| | | | | | | | | | - Use connect_through_blocks() to create connections - Remove check for spp being an integer multiple of the word size, the atomic item size feature will do that for us now - When using --nsamps, automatically terminate application after samples have been tx'd. - Added sleep statements to throttle empty while loops - Minor formatting changes
* rfnoc: replay: Add atomic item size propertyMartin Braun2022-03-021-0/+37
| | | | | | | This adds the atomic item size property to the replay block, which was originally introduced in 3e5e4eb. The effect is that it enforces streaming data to and from the block that is an integer multiple of the word size.

* tests: Add conversion benchmarking testsAaron Rossetto2022-02-281-38/+571
| | | | | | | | | | | | | This commit adds Boost test cases for benchmarking each of the existing conversions that are tested in convert_test. The benchmarks do take some time, and we do not want to run they as part of every CI run, so they are marked with a test decorator that disables the benchmark by default. To run the benchmarks, invoke convert_test with `--run-test=+benchmark*` to explicitly enable all disabled tests that begin with the word 'benchmark'. Individual benchmark test cases can be enabled by specifying the full name of the benchmark test or by crafting a wildcard that includes all benchmark test cases of interest.

* convert: Minor cleanupAaron Rossetto2022-02-282-115/+38
| | | | | | | | | | | | | | | | | | | This commit implements some minor cleanup of various converter- and convert test-related code: * Improves the log messages regarding which converter was returned for a request. * Modifies the result checking code in the converter tests to only report an out-of-range sample error once, rather than reporting every out-of-range sample encountered during the test. This vastly cuts down on the output when a conversion has failed. * Adds a function `reverse_converter()` which, given a `convert::id_type` describing a conversion from C1 to C2, returns a `convert::id_type` describing the reverse conversion (C2 to C1). * Removes two redundant test cases from the converter test.

* mpm: eeprom: Fix default values in EEPROM utilitiesMartin Braun2022-02-245-34/+113
| | | | | | | | | | | | | | | | | | | | | | | | When executing eeprom-init on E320 (which was originally written for N310), it would use defaults from N310, potentially causing issues. These issues would have arisen if we letter-revved the E320 one more time (because at rev 5, N310 had a compatibility cutover). Summary of changes: - eeprom-init will now read values *not* given on the command line from the existing content of the EEPROM, if it contains valid data. This means that DT, MCU, and rev compat values will no longer get auto-derived if the EEPROM already contained "good" values. - If the EEPROM is empty or corrupted, eeprom-init will no longer run if the pid value is not provided. This is to avoid N310 defaults being written to E320 EEPROMs. - A README is added to explain which devices use which utilities. - PID checks are more strict now. It is unlikely we'll build new devices using the old EEPROM format (prior to TLV), so we can check specifically for E320, N3x0. - The hard-coded list of PIDs for the EEPROM tools are moved to a central location (eeprom-pids.h). - The code to derive values for DT/MCU/rev compat from the rev is now pid-specific and no longer device-agnostic.

| | | | | | | | When connecting an Rx streamer to a replay block, this now allows requesting data from the replay block using a stream command. This will automatically request data from all ports the streamer is connected to, and even if there are blocks in between (depending on their action forwarding policies).

| | | | | | | rfnoc::connect_through_blocks(), unlike rfnoc_graph::connect(), did not have an argument to declare a back-edge. This patch remedies this situation by adding a skip_property_propagation argument that works exactly as with rfnoc_graph::connect().

* cmake: doxygen: Make MATHJAX_RELPATH configurable via CMakeMartin Braun2022-02-242-1/+5
| | | | | | | | | | | | | | | | | This is a Doxygen setting where to find MathJax. The default might not be suitable for everyone, and in particular, if people already have MJ installed on their local system, they might prefer using that instead of an online one. Example usage: Assume you have MathJax installed locally, e.g., through the mathjax package on Fedora, or the libjs-mathjax package on Debian/Ubuntu. Then you could build UHD as such: cmake -DMATHJAX_RELPATH=/usr/share/javascript/mathjax This will now use the local version. Note that locally generated HTML documentation can now no longer be copied to other machines, unless they also have MathJax installed to the same path.
