| * | rfnoc: Add clock selection to blocks | Martin Braun | 2019-11-26 | 1 | -0/+5 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | During registration, blocks must now specify which clock they are using for the timebase (i.e., for timed commands) and for the ctrlport (this is used to determine the length of sleeps and polls). For example, the X300 provides bus_clk and radio_clk; typically, the former is used for the control port, and the latter for the timebase clock. Another virtual clock is called "__graph__", and it means the clock is derived from property propagation via the graph. The actual clocks are provided by the mb_iface. It has two new API calls: get_timebase_clock() and get_ctrlport_clock(), which take an argument as to which clock exactly is requested. On block initialization, those clock_iface objects are copied into the block controller. The get_tick_rate() API call for blocks now exclusively checks the timebase clock_iface, and will no longer cache the current tick rate in a separate _tick_rate member variable. Block controllers can't manually modify the clock_iface, unless they also have access to the mb_controller (like the radio block), and that mb_controller has provided said access. This commit also adds the clock selection API changes to the DDC block, the Null block, and the default block. | ||||
| * | rfnoc: Make a chdr_ctrl_xport using the new link APIs | Alex Williams | 2019-11-26 | 1 | -5/+46 |
| | | | | | | | | | | | These changes add APIs to instantiate the new transports. However, only the control/management transport is currently implemented. It uses the chdr_ctrl_xport. Also update the mgmt_portal to use an ephemeral reference to the shared transport, to indicate that it has no ownership of the transport's memory. | ||||
| * | rfnoc: Added link/graph specific stream managers | Ashish Chaudhari | 2019-11-26 | 1 | -27/+25 |
| | | | | | | - Fleshed out mb_iface - Managers currently only export ctrl APIs. Data APIs TBD | ||||
| * | rfnoc: Moved chdr types/packet class out of chdr dir | Ashish Chaudhari | 2019-11-26 | 1 | -1/+1 |
| | | | | | | | - Moved chdr_packet and chdr_types from rfnoc/chdr to rfnoc and updated all references - Moved non-CHDR definitions to rfnoc_common.hpp | ||||
| * | rfnoc: Add rfnoc_device base class | Martin Braun | 2019-11-26 | 1 | -0/+1 |
| | | | | | | All USRP device impls that are RFNoC devices will need to derive from this (instead of device3). | ||||
| * | rfnoc: Add rfnoc::mb_iface interface class | Martin Braun | 2019-11-26 | 1 | -0/+76 |
| Its purpose is to provide a device-agnostic back-channel interface into the device guts for all rfnoc_graph devices. | |||||
