ebus
is a virtual device for the Extensible I/O BUS
realized with eMIPS on FPGA boards such as the BEE3, Xilinx XUP, and Xilinx
ML40x systems.
Devices on the BUS can generally be relocated and can be found by scanning the Peripheral Mapping Table at the top of the BUS physical space. The driver is responsible for identifying devices that are currently available, and to map them into the kernel virtual space during the kernel startup procedure.
The ebus
driver manages the Extensible I/O
BUS on eMIPS and provides
ebus
is always required to run the
NetBSD kernel.
