From 0bd233e64210c6605e8a6ec1424fa81f9ea8a681 Mon Sep 17 00:00:00 2001 From: Aaron Rossetto Date: Thu, 17 Oct 2019 08:44:11 -0500 Subject: uhd: Introduce I/O service manager - Implement I/O service detach link methods - The I/O service manager instantiates new I/O services or connects links to existing I/O services based on options provided by the user in stream_args. - Add a streamer ID parameter to methods to create transports so that the I/O service manager can group transports appropriately when using offload threads. - Change X300 and MPMD to use I/O service manager to connect links to I/O services. - There is now a single I/O service manager per rfnoc_graph (and it is also stored in the graph) - The I/O service manager now also knows the device args for the rfnoc_graph it was created with, and can make decisions based upon those (e.g, use a specific I/O service for DPDK, share cores between streamers, etc.) - The I/O Service Manager does not get any decision logic with this commit, though - The MB ifaces for mpmd and x300 now access this global I/O service manager - Add configuration of link parameters with overrides Co-Authored-By: Martin Braun Co-Authored-By: Aaron Rossetto --- host/lib/include/uhdlib/transport/io_service.hpp | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) (limited to 'host/lib/include/uhdlib/transport/io_service.hpp') diff --git a/host/lib/include/uhdlib/transport/io_service.hpp b/host/lib/include/uhdlib/transport/io_service.hpp index 69a3a523e..399b693dc 100644 --- a/host/lib/include/uhdlib/transport/io_service.hpp +++ b/host/lib/include/uhdlib/transport/io_service.hpp @@ -282,10 +282,19 @@ public: */ virtual void attach_send_link(send_link_if::sptr link) = 0; - /* TODO: Cleanup functions + /*! + * Detach a recv_link_if previously attached to this I/O service. + * + * \param link the recv_link_if to detach + */ virtual void detach_recv_link(recv_link_if::sptr link) = 0; + + /*! + * Detach a send_link_if previously attached to this I/O service. + * + * \param link the send_link_if to detach + */ virtual void detach_send_link(send_link_if::sptr link) = 0; - */ /*! * Create a send_io_if so a transport may send packets through the link. -- cgit v1.2.3
