NAME
firewire —
IEEE1394 High-performance Serial
Bus
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device firewireAlternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
firewire_load="YES"
DESCRIPTION
FreeBSD provides machine-independent bus support and raw drivers forfirewire interfaces.
The firewire driver consists of two
layers: the controller and the bus layer. The controller attaches to a
physical bus (like pci(4)). The firewire bus attaches to
the controller. Additional drivers can be attached to the bus.
Up to 63 devices, including the host itself, can be attached to a
firewire bus. The root node is dynamically assigned
with a PHY device function. Also, the other firewire
bus specific parameters, e.g., node ID, cycle master, isochronous resource
manager and bus manager, are dynamically assigned, after bus reset is
initiated. On the firewire bus, every device is
identified by an EUI 64 address.
Debugging over the firewire interace is possible with the dcons(4) driver. Please see https://wiki.freebsd.org/DebugWithDcons for details on how to setup debugging with firewire.
