Firewire (IEEE 1394) driver Interface Guide
===========================================

Introduction and Overview
=========================

The Linux FireWire subsystem adds some interfaces into the Linux system to
 use/maintain+any resource on IEEE 1394 bus.

The main purpose of these interfaces is to access address space on each node
on IEEE 1394 bus by ISO/IEC 13213 (IEEE 1212) procedure, and to control
isochronous resources on the bus by IEEE 1394 procedure.

Two types of interfaces are added, according to consumers of the interface. A
set of userspace interfaces is available via `firewire character devices`. A set
of kernel interfaces is available via exported symbols in `firewire-core` module.
