runway — Runway
bus
uturn* at mainbus?
The runway bus is a CPU and memory bus on
systems based on the PA-7200, PA-8000, and later CPUs. The
runway bus is a 64-bit multiplexed address/data bus
with support for cache coherency and allows up to 4-way SMP system
configurations.
One or two uturn(4)
bridges connect the runway bus to the system's
gsc(4) or
pci(4) buses.
The runway driver first appeared in
OpenBSD 3.7.
