That is for all of the zero copy implementations so far, commit cannot really error (being asynchronous). libusb zero copy impl was reworked to support the new interface. USRP1 io_impl with the psuedo managed buffer was replaced with safe_make. Also, usrp1 io_impl was simplified greatly due to commit returning void now. UDP zero copy asio was disabled (in this commit, until its reworked). Phony send and recv interfaces were removed completely. --- host/include/uhd/transport/zero_copy.hpp | 112 +++++++--------------- host/lib/transport/CMakeLists.txt | 4 +- host/lib/transport/libusb1_zero_copy.cpp | 149 +++++++----------------------- host/lib/transport/vrt_packet_handler.hpp | 4 +- host/lib/transport/zero_copy.cpp | 121 +++++++++--------------- host/lib/usrp/usrp1/io_impl.cpp | 65 ++++--------- 6 files changed, 130 insertions(+), 325 deletions(-) (limited to 'host/lib/usrp/usrp1') diff --git a/host/include/uhd/transport/zero_copy.hpp b/host/include/uhd/transport/zero_copy.hpp index ba19b193c..9dd16280c 100644 --- a/host/include/uhd/transport/zero_copy.hpp +++ b/host/include/uhd/transport/zero_copy.hpp @@ -19,10 +19,10 @@ #define INCLUDED_UHD_TRANSPORT_ZERO_COPY_HPP #include -#include #include #include #include +#include namespace uhd{ namespace transport{ @@ -34,14 +34,27 @@ namespace uhd{ namespace transport{ class UHD_API managed_recv_buffer : boost::noncopyable{ public: typedef boost::shared_ptr sptr; + typedef boost::function release_fcn_t; + + /*!
