Detailed Description

template<typename channel_t = int>
class dxd::streaming::channels< channel_t >

one client's planar channel double buffers for one pin

Kernel streaming staging: the client's engine works on these instead of the ring, and the device's tick de-/interleaves them against it. The control block carries the frame counter and the last two buffer switch timestamps.
