2009-09-04Untested fixes for getting serdes onto the new fifo system. Compiles, at leastMatt Ettus
2009-09-04Implement Eth flow control using pause framesMatt Ettus
Not fully tested, but it seems to work without frame errors, sequence number errors or ethernet overruns. Still of course will get tx underruns on a slow machine, and the transmitted signal has some issues though.

* 'new_eth' of http://gnuradio.org/git/matt: properly set the address filter stop sending short ethernet command packets. Fix problem with commands timing out (specifically stop_rx_streaming) Fix race condition that caused commands such as stop_rx_streaming to fail. Fixing a line in the clock recovery algorithm. This works with a bit larger error than there proably should be. Better fix for broken AC_PROG_F77 macro Fix Python header check failure due to invalid cached state waterfall and fft use a common autoscale function Fix so that the waterfall texture is initialized with a buffer of the same size. Modifications to usrp2 source and sink so that set center freq is called afer set lo offset. Modifications to the usrp blocks and wrapper so that the lo offset is set with the lo frequency. Removed subversion related configuration info. Expand frequency ranges to match hardware capability. Modified log power fft block so ref scale is peak to peak. Adding clock sync algorithm using PFB. This works, but needs a bit more work.

The old mac used to do this automatically.

2009-09-04Fix problem with commands timing out (specifically stop_rx_streaming)Eric Blossom
After fixing the race, this change uses Tom's idea to stop enqueuing data when trying to stop, and adds a new flush_rx_samples method to drop any samples that may have already been accumulated. I ran Tom's test case 500 times with 0 failures ;-)
2009-09-04Fix race condition that caused commands such as stop_rx_streaming to fail.Eric Blossom
This fixes the bulk of the problem. Next step is to drop data packets while waiting for the reply.

2009-09-02Fix so that the waterfall texture is initialized with a buffer of the same size.Josh Blum
If the fft size was a non power of two, the buffer would be a different size. This would cause a segfault. Particularly because fft_window was throwing out a bin.

* Modified log power fft block so ref scale is peak to peak. * Tweaked fft sink autoscale routine to come up with better numbers. * Modified scope sink ac couple block to use constant tap. The previous tap calculation would cause failure for very small sample rates.
