Zio -- the Ultimate I/O framework
This project hosts a new I/O framework for the Linux kernel.
We plan to submit it, sooner or later, but currently the git tree on
ohwr is the official development place.
Our initial analysis of existing framework revealed they are not
matching our requirement list.
Documentation
The documentation lives within the repository.
Sometimes we release a pdf to the
files section of ohwr.
As I write this, the latest manual is
https://www.ohwr.org/project/zio/uploads/3a3217597796f47d3c108e98541922c1/zio-manual-130121-v1.0.pdf
(little has changed since release 1.0, as the framework is stable and
solid).
In the same place you find the slides for the presentations we held, at
conferences
or internally.
Initial documents
- requirements: A list of requirements for your I/O machinery
- comedi: A discussion of comedi, and why it doesn't suit our needs
- iio: A discussion of iio, and why it doesn't suit our needs
Technical pages only available on the wiki
- types: list of types and data structures used in ZIO beta2 and later
- readme: the readme for beta2 that quicky summarizes current zio code
-
performance: a measure of the overhead of ZIO over
plain
readof data - todo: things we need to fix or add and a tentative schedule
