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.
