Cover letter [RFC PATCH 0/7] Introducing ZIO, a new I/O framework
This RFC patch-set introduces the ZIO framework for input/output, which will be used in the new series of drivers by the BE-CO-HT group at CERN.
The use-case it is meant to cover is very fast I/O with hardware-provided timestamps. The first production driver we will support is a 100Ms/s 4-channel 14-bit ADC (developed on ohwr: see
http://www.ohwr.org/projects/fmc-adc-100m14b4cha ). We need similar bandwidth on output.
The synchronization engine of that FMC card and other ones is going to be White Rabbit (http://www.ohwr.org/projects/white-rabbit).
Currently, the patch-set includes one example driver (zio-zero) that behaves like /dev/zero and /dev/urandom. Other drivers will come soon, both demo and real hardware.
Slides for a tutorial on the design ideas are online here:
