Re: [Discuss-gnuradio] gnuradio on ARM: gr_vmcircbuf_sysv_shm: shmat (3): Invalid argument

[Philip Balister]

The circular buffer allocator chooses form about three different ways of
setting up the buffer. The shm version does not work on ARM.

The circular buffer is going to become more and more painful as we try
to do cool stuff with Zynq.

That is all.
