* rfnoc: Change Block-ID format to 0/FFT#1Martin Braun2019-11-261-1/+1
| | | | | | | Previously, it was 0/FFT_1. The counter was separated by an underscore. Now, we separate by a # symbol to allow for underscores in block names. This means 'FIR_Filter' is now a valid blockname.
* rfnoc: Add block registry/factory and make_argsMartin Braun2019-11-263-0/+108
| | | | | | - noc_block_base now has a ctor defined - The registry stores factory functions to the individual Noc-Block implementations
* rfnoc: Add block_poke support to reg_iface async msgAshish Chaudhari2019-11-261-4/+4
| | | | | The async message callback now has a vector of data words instead of a single one
* rfnoc: adding client_zeroBrent Stapleton2019-11-262-0/+214
| | | | | | | | | | - Adding client_zero class, which gathers information about our device form the global registers on port 0 of the RFNoC backend registers. - adding unit tests to exercise client_zero - mock_reg_iface class: adding fake register_iface so we can run unit tests in software only Co-authored-by: Martin Braun <martin.braun@ettus.com>
* rfnoc: Added impl for reg_iface and ctrl_endpointAshish Chaudhari2019-11-264-1/+655
| | | | | | | | - Added new register_iface class that translates high-level peek/poke calls into CHDR control payloads - Added new chdr_ctrl_endpoint class that emulates a control stream endpoint in SW. It can create and handle multiple register interfaces
* rfnoc: node: Add default command time APIMartin Braun2019-11-261-0/+23
|
* rfnoc: Add action APIMartin Braun2019-11-264-0/+187
| | | | | | | | - Added action_info class - Allow to send actions from node to node - Allow to post actions into nodes - Allow to set default forwarding policies - Added unit tests
* rfnoc: Added initial impl for mgmt_portalAshish Chaudhari2019-11-262-1/+998
| | | | | | | - The management portal is the interface for the framework to allow discovering the data topology, setup routes between stream endpoints and configure streamers - Use a zero_copy_if and the mgmt_paylod to send/recv packets
* rfnoc: Refactored CHDR packet interfacesAshish Chaudhari2019-11-264-0/+656
| | | | | | | - Moved packet interface code from public to private include - Split packet interface into two files: payload paring and packet iface - Added support for all CHDR packet types - Added more test cases to unit test
* rfnoc: Add property propagation, Boost.Graph storageMartin Braun2019-11-263-9/+764
| | | | | | | | | | | | - Adds a detail::graph_t class, which handles the propagation - Adds methods to node_t to aid with propagation - Adds unit tests - Adds dynamic property forwarding: Nodes are now able to forward properties they don't know about by providing a forwarding policy. A good example is the FIFO block which simply forwards most properties verbatim. - node: Temporarily disabling consistency check at init
* rfnoc: Add detail::block_container_t classMartin Braun2019-11-262-0/+75
| | | | | This is a storage for the noc_block_base derivatives. It supports finding blocks.
* rfnoc: Add noc_block_base classMartin Braun2019-11-262-0/+12
| | | | This is a parent class for all block controllers.
* rfnoc: Add properties, nodes, and accessorsMartin Braun2019-11-262-0/+120
| | | | | | | | | | | | | | Adds the following classes: - uhd::rfnoc::node_t, the base class for RFNoC nodes - uhd::rfnoc::node_accessor_t, a class to access private properties - uhd::rfnoc::res_source_info, a struct that identifies where properties come from - uhd::rfnoc::property_t, and property_base_t (its parent) - uhd::rfnoc::prop_accessor_t, a class to access properties Add always dirty property (dirtifier). Also adds unit tests for properties.
* rfnoc: block_id: Add more info when ctor failsMartin Braun2019-11-261-1/+2

* rfnoc: Read cmd FIFO size from blocks & configure ctrl_ifaceMartin Braun2019-09-042-4/+18
| | | | | | | | | | This requires noc_shell compat number 6.0. It will allow sending as many command packets, but no more, than there is space. Updated FPGA images for devices: - X310/X300 - N300/N310/N320 - E310/E320
* RFNoC: Re-enable flow ctrl for blocks on same xbarMichael West2019-08-141-1/+1
| | | | | | | | | | | Prior commit disabled flow control for all lossless links, including links between blocks on the same crossbar. That caused packets to jam up the crossbar leading to control packets failing to ACK under certain conditions. This reverts it so flow control is enabled and the crossbar is kept clear.

* rfnoc: fix multidevice graph connectionsMark Meserve2019-08-061-96/+107
| | | | | | | - Fixes an issue where a multi-device device3 object would cause connections to be generated across devices in legacy_compat - The connect_blocks function previously assumed that find_blocks would always return blocks in the same device number order
* rfnoc: Add update_graph() API callMartin Braun2019-07-153-12/+9
| | | | | | Blocks that change scaling, tick rate, or sampling rate can now notify the graph to update streamers. Before, this was handled only by mult_usrp, and only for DDC and DUC blocks.
* device3: Remove unused 'rate' argument from update_?x_streamers()Martin Braun2019-07-151-2/+2

* device3: rfnoc: formatting changesBrent Stapleton2019-07-152-9/+10

* rfnoc: tick_node: Search all nodes for tick ratesMartin Braun2019-05-081-3/+5
| | | | | | | | | | | | | | | | | The tick_node was trying to find the current tick rate by only querying active blocks (i.e., blocks that were flagged active-streaming). However, this is not necessary since we require all blocks to run at the same tick rate. In theory, querying active-only ports should be fine, but due to some idiosyncrasies in our current graph code, connecting a single streamer to channel 1 (out of 0, 1) would try and get the info from the wrong port. This is not a fix to the graph code, but the change to tick_node is also appropriate and is sufficient to fix the "late packets on channel 1" issue. This issue would manifest when sending timed packats to channel 1 in a single-channel streamer. The problem is that it wouldn't be able to read the correct tick rate.
* device3: Constraint send/recv_frame_size based on down/upstream MTUSugandha Gupta2019-05-013-5/+27
| | | | | | We need to properly contraint the send/recv_frame_size based on the minimum MTU of all the down/upstream blocks. This fixes the issue with E310 tx/rx streaming as it has smaller MTU sizes than the other usrps.
* TwinRX: Fix duplicate write to N value in DDCmichael-west2019-03-261-2/+1
| | | | | | | The N value was getting written twice and the second value being written was 1, which works for all use cases except when using TwinRX. This change fixes several issues with TwinRX including streaming failing to stop cleanly and incorrect decimation.
* uhd: mpm: update all license header w/ "-or-later"Brent Stapleton2019-03-082-2/+2
| | | | Updating all SPDX license identifiers to include "-or-later"
* RFNoC: Remove incorrect flushMichael West2019-03-051-19/+0
| | | | | | | | | | | | Removing the flush in configure_flow_control_out(). The flush is done incorrectly because it just disables flow control and allows packets to dump onto the crossbar, which could lock it up. It is also incorrect to flush when connecting blocks. A connect should just configure the SID and flow control and let any existing data flow to the newly connected block. Flushing of a block should only be done during creation or destruction of the block. Signed-off-by: Michael West <michael.west@ettus.com>
* Revert "RFNoC: Fix flush in source_block_ctrl_base"Michael West2019-03-051-1/+18

* lib: Fix various type-conversion compiler warningsMartin Braun2019-02-284-5/+7
| | | | | This makes more type-conversions explicit, to reduce the number of warnings specifically for MSVC.
* RFNoC: Fix flush in source_block_ctrl_baseMichael West2019-02-181-18/+1
| | | | | | | | | | The configure_flow_control_out function was set to dump any packets onto the crossbar, which could cause issues on the crossbar and in downstream blocks. Replacing wil a call to the _flush() function in the block_ctrl_base parent class, which drops the packets so they do not get put onto the crossbar.

* RFNoC: Disable FC ACK packets for lossless linksMichael West2019-02-182-8/+15
| | | | | | | FC ACK packets are unnecessary on lossless links and degrade overall performance. This change disables those packets on all lossless links. Signed-off-by: Michael West <michael.west@ettus.com>

* X300: Fix tick and sample rate settingmichael-west2019-01-311-6/+8
| | | | | | | | | | | | - Removed incorrect function call to set tick rate in x300_radio_ctrl_impl. - Modified legacy compat layer to properly set tick and sample rates. These changes eliminate the tick and sample rate warnings during X300 initialization if TwinRX is used and allow for TwinRX to be used alongside other types of daughterboards in the same X300.

* RFNoC: Fix scaling of M and N values in DDC/DUCmichael-west2019-01-312-3/+10
| | | | | | | Scale the M and N values if the tick_rate differs from the sample rate. Fixes timestamps in packets when using TwinRX on X300. Signed-off-by: michael-west <michael.west@ettus.com>

* transport: muxed_zero_copy_if fixesmichael-west2019-01-211-1/+1
| | | | | | | | | | Changed muxed_zero_copy_if to make each stream buffer the same number of frames as the underlying transport and changed the size of the underlying control transport for X300 and MPMD devices to match the size of the command FIFO in order to prevent starvation of any single control transport. Added some constants to remove hard coded values. Signed-off-by: michael-west <michael.west@ettus.com>
* rfnoc: Fix detection of outstanding acks by ctrl_ifaceMartin Braun2019-01-171-4/+3
| | | | | | | 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

* RFNoC: Fix stream command propagationmichael-west2018-12-201-1/+1
| | | | | | - Corrects parameter from output port to input port of node - Fixes issue on nodes with different number of input and output connections
* RFNoC: Fix graph traversalmichael-west2018-12-193-14/+16
| | | | | | - Allows different TX sample rates on separate channels - Prevents stream commands from being issued on wrong ports - Prevents some receive timeout errors
* Device3: Fix block control flushingBrent Stapleton2018-12-171-18/+25
| | | | | | | | | | | | | | | | | | | - Factor out the _start_drain helper function, which starts flushing data out of the block. We should always be disabling flow control after we write to the flushing registers. - Always attempt to flush when calling the _flush function. Previously, we would check if data appeared to be moving when _flush was called, and only write to the flush registers if data was moving. However, if data is stuck for some reason (for example, the block ran out of flow control credits), this check will give us a false positive, and we won't flush. Instead, we need to always begin the flushing process, then check those counters, and return once the counters stop changing. Note: we need to start flushing before disabling flow control so that the flushed data isn't flooded onto the crossbar.

* Device3: Set default block control response SIDsBrent Stapleton2018-12-171-0/+4
| | | | | | | | | | | In the block controllers, set the default response SIDs for input and output ports. If we don't do this, the blocks may send their responses to other blocks' responses ports. For example, without this change, the DDC may send an error packet to port 0x0000, which is assigned to the DmaFIFO. With this change, the DDC would send that packet to 0xFFFF, which isn't assigned to any other block.
* rfnoc: Add halt to replay APIWade Fife2018-11-271-0/+4
| | | | | The HALT feature allows a command that takes a long time to run to be stopped while it is in progress.
* rfnoc: Fix default SPP for replayWade Fife2018-11-271-4/+3
| | | | Consolidate two constants for default replay packet size down to one.
* cmake: Update coding style to use lowercase commandsMartin Braun2018-11-141-4/+4
| | | | | | | | | | | | | | | | | Also updates our coding style file. Ancient CMake versions required upper-case commands. Later command names became case-insensitive. Now the preferred style is lower-case. Run the following shell code (with GNU compliant sed): cmake --help-command-list | grep -v "cmake version" | while read c; do echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g' done > convert.sed \ && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' \ '*CMakeLists.txt' | xargs -0 gsed -i -f convert.sed && rm convert.sed (Make sure the backslashes don't get mangled!)
