Broadcom AMBA Backplane driver
SYNOPSISTo 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" DESCRIPTIONThebcma 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 ALSObhnd(4), intro(4), siba(4)HISTORYThebcma device driver first appeared in
FreeBSD 11.0.
