    Subject[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:

    Alessandro Rubini (5):
    Documentation: add docs for drivers/zio
    include/linux: add headers for drivers/zio
    drivers/zio: add triggers and buffers
    drivers/zio: add user-space tool zio-dump
    zio: insert in Kbuild so it is actually compiled

    Federico Vaga (2):
    drivers/zio: core files for the ZIO input/output framework
    drivers/zio: add the zio-zero device driver
