MAINBUS(4) | Device Drivers Manual | MAINBUS(4)

# NAME

`mainbus` — device tree root

# SYNOPSIS

`mainbus0 at root`

# DESCRIPTION

`mainbus` provides an abstraction for all system buses to attach to. It is the start of the device tree and always attached. It is not a physical device as such, but an abstraction to which other devices may attach.

The actual buses which attach are largely machine-dependent; refer to the individual man pages for more information.
