Subject: [RFC PATCH 0/7] Introducing ZIO, a new I/O framework
Date: Sat, 26 Nov 2011 18:30:08 +0100 [thread overview]
Message-ID: <cover.1322328073.git.rubini@gnudd.com> (raw)
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:
