* formatting: preparing for uhd::math cleanupBrent Stapleton2019-01-185-971/+1129
| | | | Formatting files that will be touched in upcoming changes to uhd::math
* rfnoc: Fix detection of outstanding acks by ctrl_ifaceMartin Braun2019-01-172-5/+4
| | | | | | | There was a bug where the number of outstanding ACKS in RFNoC's ctrl_iface was derived from the number of recv frames, which was wrong. A number that was too low would effectively break timed commands on tune, which would, e.g., affect phase alignment.
* lib: rfnoc: apply clang-formatMartin Braun2019-01-1729-1905/+1859
| | | | | | This is a continuation of 967be2a4. $ clang-format -i -style=file host/lib/rfnoc/*.cpp
* formatting: Add modified clang-format for headersMartin Braun2019-01-171-0/+94
| | | | | | | Because our headers do not require C++11, they need a different syntax (e.g., vector<vector<int> >, note the space between the >). Since some editors automatically pick up a .clang-format from a parent dir, this helps when editing headers.

* uhd: mpm: apply clang-format to all filesBrent Stapleton2019-01-16279-20123/+20150
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Applying formatting changes to all .cpp and .hpp files in the following directories: ``` find host/examples/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/tests/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/dboard/neon/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/dboard/magnesium/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/device3/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/mpmd/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/x300/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/utils/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find mpm/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file ``` Also formatted host/include/, except Cpp03 was used as a the language standard instead of Cpp11. ``` sed -i 's/ Cpp11/ Cpp03/g' .clang-format find host/include/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file ``` Formatting style was designated by the .clang-format file.
* ascii_art_dft: move example within include guardBrent Stapleton2019-01-161-2/+1
| | | | | Moving the example `main` within the include guards for the file. This is mostly to help clang-format's include guard detection.
* formatting: remove vim hints in headersBrent Stapleton2019-01-1643-43/+0
| | | | | Remove trailing vim hints in header files. This functionality will be replaced by clang-format.
* examples: utils: skip formatting program optionsBrent Stapleton2019-01-1642-0/+84
| | | | | | Turning off clang formatting around the program option declarations. clang-format makes them looks bad an unreadable because it thinks the options are function calls or something.
* uhd: skip formatting misc arrays, maps, etc.Brent Stapleton2019-01-168-1/+20
| | | | | | Various data structures are nicely formatted to be human-readable. clang-format makes these structures harder to read, so we can skip formatting these sections.
* transport: Move uhd-dpdk header to uhdlibAlex Williams2019-01-154-3/+3

* tests: Add arguments to dpdk_test to control core mappingAlex Williams2019-01-151-40/+100
|
* tests: Add unit test for DPDK transportAlex Williams2019-01-152-0/+353
| | | | | | | | | This commit adds a loopback benchmark for a PC with 2 DPDK-compatible NIC ports that are connected together via a cable. It sends messages with embedded sequence numbers (outgoing and last-seen) for maintaining a flow control window of packets in flight. It tracks the number of bytes sent/received and reports the time the test took and average throughput.
* transport: Add dpdk_zero_copy transportAlex Williams2019-01-153-0/+527
| | | | | This transport is based on uhd-dpdk, and it includes a global context that must be initialized prior to creating any dpdk_zero_copy objects.
* transport: Add blocking recv calls to uhd-dpdkAlex Williams2019-01-1511-220/+704
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds an internal wait queue API to uhd-dpdk. Socket configuration requests had their blocking calls re-implemented on top of this API, and it is also used to service requests to wait on RX packets (w/ timeout). The wait API involves a multi-producer, single-consumer queue per I/O thread (waiter_ring), with a condition variable used for sleeping. The data structure is shared between user thread and I/O thread, and because timeouts make resource release time non-deterministic, we use reference counting on the shared resource. One reference is generated by the user thread and passed to the I/O thread to consume. A user thread that still needs the data after waking must get() another reference, to postpone the destruction of the resource until it is done. Timeouts are based on CLOCK_MONOTONIC. For recv, a timeout of 0 indicates blocking indefinitely, and a negative timeout indicates no timeout is desired. Also drop timeout for closing sockets in uhd-dpdk. The timeout would allow a user thread to pre-empt the I/O thread's cleanup process. The user thread would free data structures the I/O thread still needed to function. Since this timeout is superfluous anyway, let's just get rid of it. Also add some more input checking and error reporting.
* uhd-dpdk: Add ARP responder, set MTU, and clean up APIAlex Williams2019-01-155-7/+75
| | | | | | | | | | | | Set MTU of Ethernet ports: Some NICs (like the Mellanox ones) require this to work. Add ARP responder to uhd-dpdk. Clean up pending ARP request list when done: Threads waiting for an ARP request to complete would be woken up when the request completed, but they wouldn't get removed from the list of pending requests. This fixes the issue.
* docs: Add comments for TwinRX and MCRMartin Braun2019-01-152-0/+25
| | | | | | The TwinRX dboards only support a master clock rate of 200 MHz, which is now emphasized in the manual. In addition, the meaning of tick rate, sampling rate, and master clock rate in the TwinRX context is explained.
* includes: Make sure BOOST_VERSION is always availableMartin Braun2019-01-151-0/+1
| | | | | Boost changed the includes, and boost/version.hpp was being implicitly imported. This makes the include explicit.
* examples: Improved error message in tx_waveformsDerek Kozel2019-01-141-2/+6
| | | | Non-CONST type waveforms require a non-zero wave freq
* mpmd: increase claim_rpc call timeout.Trung Tran2019-01-142-3/+6
| | | | | | | | | | | During certain RPC calls (e.g. update_component), the MPM RPC server is slow to respond to reclaim requests, which can causes RPC timeouts. These changes fix those timeouts. By setting the reclaiming timeout to twice the timeout of an RPC call, we have some margin for error on the host side, while not affecting the underlying claiming logic in MPM. The loop should still operate on a 5 second period, but now has more leeway during stressful conditions.
* rpc,mpmd: replace all set_timeout() to new apiTrung Tran2019-01-144-58/+11
| | | | | Using new rpc client new API that ensure atomic setting of timeout on each rpc call.
* mpmd_impl: move timeout constants to headerTrung Tran2019-01-142-9/+13
|
* utils:rpc: set rpc timeout during rpc callTrung Tran2019-01-141-3/+120
| | | | | | | | | | | | | The current implementation of the UHD RPC client has a timeout that is being accessed non-atomically. Many calls follow the pattern: 1. set_timeout(value) 2. request_rpc() 3. set_timeout(default) which is not atomic. Other concurrent calls on the same rpc client may change the timeout value; leads to unexpected behavior These new set of function will, instead, handle setting and re-setting the timeout atomically in the RPC request.

| | | | | Add a benchmark of packet handlers and device3 flow control. Benchmarks use mock transport objects.
* uhd: Move device3 flow control functions to header for benchmarkCiro Nishiguchi2019-01-102-291/+306
| | | | | Moving device3 flow control functions to a header file so they can be included in benchmark utility.

* lib: experts: Add potentially missing but sometimes inferred includeMartin Braun2019-01-091-0/+1
| | | | | This adds an include for boost/core/noncopyable.hpp. Without it, builds would potentially fail on Boost 1.69++.
* rh: adjust frequencies for lo filter bankMark Meserve2019-01-081-1/+1
| | | | | - Moves the cutover frequency for the 900 MHz LO filter from 900 to 975 MHz. This fixes an image issue in TX when transmitting near 325 MHz or 900 MHz.

| | | | Some versions of MSVC report issues without it.
* b200: Fix compiler warnings related to type conversionsMartin Braun2019-01-072-8/+8
| | | | | | | These compiler warnings mostly pop up on MSVC. Most of them are due to inconsistent usage of size_t, uint{8,16,32}_t, and even int. This commit changes types mostly such that variables have the correct type to begin with, although it also contains a few explicit type-casts.
* x300: Fix compiler warnings related to type conversionsMartin Braun2019-01-074-15/+15

* devtest: Fix CMake `endif` warningBrent Stapleton2019-01-031-1/+1
| | | | When adding E320 devtests, the `endif` clause had the wrong argument, which resulted in a CMake warning.
* transport: Fix MSVC warning by replacing size_t with uint32_tMartin Braun2019-01-031-1/+1
| | | | This fixes a C4267 which pops up a lot when compiling UHD with MSVC.
* log: Fix MSVC warnings by changing a size_t to unsigned intMartin Braun2019-01-031-1/+1
| | | | This fixes a warning C4267 which pops up a lot in this file.
* examples: optimize tx_waveforms memory allocationsBrent Stapleton2019-01-031-5/+10
| | | | | | | Move filling the TX buffer outside the critical path. Now, we pre-fill the TX buffer before entering the send loop (and before setting the TX stream time), and fill the TX buffer after calling send() (for the next iteration).
* examples: formatting in tx_waveformsBrent Stapleton2019-01-031-2/+8
| | | | | - Format `if` statements to multiple lines - Add quick comment on the exit checks
* examples: optimize benchmark_rate start timeBrent Stapleton2019-01-031-3/+3
| | | | | | | | Move the setting of the streaming start times back as late as possible. Currently, there are memory allocations in between setting the time_spec in the TX metadata and actually starting streaming. This will lessen the need for an INIT_DELAY and decrease the probability of late packets.
