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 siba
Alternatively, to load the driver as a module at boot time, place the following
line in
loader.conf(5):
DESCRIPTION¶
The
siba
driver supports the Sonic Inc.
Silicon Backplane, the interblock communications architecture that can be
found in most Broadcom wireless NICs.
A bus 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 NIC uses a chip from the same chip family. Each member of the family
contains a different set of cores, but shares basic architectural features
such as address space definition, interrupt and error architecture, and
backplane register definitions.
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.
All cores other than PCMCIA have a target agent.
