NAME

     siba — Sonic Inc. Silicon Backplane driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

           device bhnd
           device siba

     Alternatively, to load the driver as a module at boot time, place the following line in 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.
