2009-09-15 | Applied libusb-1.0 patch set from Thomas Tsou <ttsou@vt.edu>: | Johnathan Corgan | |
This patch set updates the usrp to support libusb-1.0. Asynchronous I/O through libusb is added with fusb_libusb1.*, which is heavily based on fusb_linux.*. In short, URB's and ioctl calls are replaced with libusb_transfer structs and native calls. Transfer reaping is handled by libusb and associated callbacks. I get 32Mb/s on all of my machines using test_usrp_standard_rx or tx. Due to the API rewrite in 1.0 from 0.12, there are alot of changes, many are simply name changes. Known Issues: Transmit and receive both work, but not at same time (e.g. usrp_benchmark_usb.py). libusb does not create any internal threads, so for a single session fusb_libusb1 works in the same manner as fusb_linux with the callback called at controlled times. With multiple libusb sessions the callback may occur at any time and threading issues come into play causing behavior to become undefined. The use of separate libusb_contexts _might_ solve this issue; I have not had the time to look into it. | |||

* Public USRP(1) header files are now in their own source directory and install into $(includedir)/usrp. This was done to avoid name clashes in the top-level include directory. Only users who are developing directly to libusrp in C++ are affected; the GNU Radio C++ and Python APIs are unchanged. The simple change required by this update is to change: #include <usrp_*.h> to #include <usrp/usrp_*.h> ...in your source code. * Removed usrp-inband code from tree (put into limbo directory.) This code has become unmaintained and has started to suffer from bitrot. A checkpoint tag has been made for anyone still needing to use it: http://gnuradio.org/svn/gnuradio/tags/checkpoints/trunk-20090708-pre-usrp-reorg The plan during the 3.2->3.3 development cycle is to replace the functions done by the in-band code with extensions to the existing gr-usrp blocks using the new message passing architecture. The USRP hardware FPGA code that provided the inband interface has not been removed; however, it too has become unmaintained and will likely be rewritten/replaced during the 3.3 timeframe. The trunk passes distcheck. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@11394 221aa14e-8319-0410-a670-987f0aec2ac5 | |||
