BCMA(4) FreeBSD Kernel Interfaces Manual BCMA(4)
NAME bcma - Broadcom AMBA Backplane driver
SYNOPSIS To compile this driver into the kernel, add the following lines to the kernel configuration file:
device bhnd device bcma
To load the driver as a module at boot, add this line to loader.conf(5):
bcma_load="YES"
DESCRIPTION The bcma driver provides bhnd(4) support for devices using the ARM AMBA- based backplane architecture found in later Broadcom Home Networking Division's network chipsets and embedded systems.
A common interconnect connects all of the backplane's functional blocks. These functional blocks, known as cores, use the ARM AMBA AXI or APB interface to communicate with devices attached to the interconnect.
The IP cores used in siba(4) devices were adapted by Broadcom for compatibility with the new interconnect.
SEE ALSO bhnd(4), intro(4), siba(4)
HISTORY The bcma device driver first appeared in FreeBSD 11.0.
AUTHORS The bcma driver was written by Landon Fuller <landonf@FreeBSD.org>.
