SIBA(4) FreeBSD Kernel Interfaces Manual SIBA(4)
NAME
siba - Sonic Inc. Silicon Backplane driver
SYNOPSIS
To compile this driver into the kernel, add the following lines to the
kernel configuration file:
device bhnd
device siba
To load the driver as a module at boot, add this line to loader.conf(5):
siba_load="YES"
DESCRIPTION
The siba driver provides bhnd(4) support for devices based on the Sonic
Inc. Silicon Backplane, an interblock communications architecture found
in earlier Broadcom Home Networking Division wireless chipsets and
embedded systems.
A common interconnect connects all of the Silicon Backplane's functional
blocks. These functional blocks, known as cores, use the Open Core
Protocol (OCP) interface to communicate with agents attached to the
Silicon Backplane.
Each core can have an initiator agent that passes read and write requests
onto the system backplane and a target agent that returns responses to
those requests. Not all cores contain both an initiator and a target
agent. Initiator agents are present in cores that contain host
interfaces (PCI, PCMCIA), embedded processors (MIPS), or DMA processors
associated with communications cores.

HISTORY
The siba device driver first appeared in FreeBSD 8.0. The driver was
rewritten for FreeBSD 11.0 to support the common Broadcom bhnd(4) bus
interface.
AUTHORS
The siba driver was originally written by Bruce M. Simpson
<bms@FreeBSD.org> and Weongyo Jeong <weongyo@FreeBSD.org>. The driver
was rewritten for FreeBSD 11.0 by Landon Fuller <landonf@FreeBSD.org>.
