NAME
bonito —
memory and PCI or PCI-X
controller
SYNOPSIS
bonito0 at mainbus0
pci0 at bonito?
DESCRIPTION
The bonito driver supports both the
Algorithmics Bonito64 memory and PCI controller on Loongson 2E-based
systems, or the onboard memory and PCI-X controller found on Loongson
2F-based systems, which is a very close design, albeit not compatible with
the original Bonito.
Differences between the two models of controllers are hidden at
the bonito driver level.
The bonito driver also handles PCI
interrupt routing; on systems featuring a glxpcib(4) PCI-ISA bridge to which legacy devices are
connected, it will also handle legacy interrupts.
