That is, with a smaller booty, the managed buffers will get freed up and the call to get buffer will never block waiting for a buffer to become free. This has several side effects: 1) Overflows are more likely to occur in the pirate thread. Pirate-based overflows will overwrite old packets, whereas socket-based overflows will discard newer incoming packets. 2) The pirate thread will continue to pull in async packets rather than loosing them in a socket-based overflow. --- host/lib/usrp/usrp2/io_impl.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'host/lib/usrp') diff --git a/host/lib/usrp/usrp2/io_impl.cpp b/host/lib/usrp/usrp2/io_impl.cpp index eba704059..bbe9c273f 100644 --- a/host/lib/usrp/usrp2/io_impl.cpp +++ b/host/lib/usrp/usrp2/io_impl.cpp @@ -46,7 +46,7 @@ struct usrp2_impl::io_impl{ io_impl(size_t num_frames, size_t width): packet_handler_recv_state(width), - recv_pirate_booty(alignment_buffer_type::make(num_frames, width)), + recv_pirate_booty(alignment_buffer_type::make(num_frames-3, width)), async_msg_fifo(bounded_buffer::make(100/*messages deep*/)) { /* NOP */ -- cgit v1.2.3 From c861f98c55c38250a0d87ed91f5c19b10192a4b8 Mon Sep 17 00:00:00 2001 From: Josh Blum Date: Sat, 16 Oct 2010 18:07:10 -0700 Subject: usrp: created multi-usrp (multi chan, multi board), and deprecated mimo-usrp --- host/include/uhd/usrp/CMakeLists.txt | 1 + host/include/uhd/usrp/mimo_usrp.hpp | 4 +- host/include/uhd/usrp/multi_usrp.hpp | 259 +++++++++++++++++++++ host/include/uhd/usrp/single_usrp.hpp | 6 +- host/lib/usrp/CMakeLists.txt | 1 + host/lib/usrp/mimo_usrp.cpp | 6 + host/lib/usrp/multi_usrp.cpp | 422 ++++++++++++++++++++++++++++++++++ host/lib/usrp/single_usrp.cpp | 4 - 8 files changed, 694 insertions(+), 9 deletions(-) create mode 100644 host/include/uhd/usrp/multi_usrp.hpp create mode 100644 host/lib/usrp/multi_usrp.cpp (limited to 'host/lib/usrp') diff --git a/host/include/uhd/usrp/CMakeLists.txt b/host/include/uhd/usrp/CMakeLists.txt index f973e401a..abddf3951 100644 --- a/host/include/uhd/usrp/CMakeLists.txt +++ b/host/include/uhd/usrp/CMakeLists.txt @@ -42,6 +42,7 @@ INSTALL(FILES simple_usrp.hpp single_usrp.hpp mimo_usrp.hpp + multi_usrp.hpp DESTINATION ${INCLUDE_DIR}/uhd/usrp ) diff --git a/host/include/uhd/usrp/mimo_usrp.hpp b/host/include/uhd/usrp/mimo_usrp.hpp index bdd84a148..7c250b2fd 100644 --- a/host/include/uhd/usrp/mimo_usrp.hpp +++ b/host/include/uhd/usrp/mimo_usrp.hpp @@ -32,12 +32,12 @@ namespace uhd{ namespace usrp{ /*! - * The MIMO USRP device class: + * The MIMO USRP device class (DEPRECATED): * A mimo usrp facilitates ease-of-use for multi-usrp scenarios. * The wrapper provides convenience functions to control the group * of underlying devices as if they consisted of a single device. */ -class UHD_API mimo_usrp : boost::noncopyable{ +class UHD_API UHD_DEPRECATED mimo_usrp : boost::noncopyable{ public: typedef boost::shared_ptr sptr; diff --git a/host/include/uhd/usrp/multi_usrp.hpp b/host/include/uhd/usrp/multi_usrp.hpp new file mode 100644 index 000000000..65c7e9044 --- /dev/null +++ b/host/include/uhd/usrp/multi_usrp.hpp @@ -0,0 +1,259 @@ +// +// Copyright 2010 Ettus Research LLC +// +// This program is free software: you can redistribute it and/or modify +// it under the terms of the GNU General Public License as published by +// the Free Software Foundation, either version 3 of the License, or +// (at your option) any later version. +// +// This program is distributed in the hope that it will be useful, +// but WITHOUT ANY WARRANTY; without even the implied warranty of +// MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
