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>.
