National Semiconductor PC87560 Legacy IO
The ssio
driver provides support for the National
Semiconductor PC87560 Legacy IO chip on systems with PA-8500 and later 64-bit
CPUs. It configures the Programmable Interrupt Controllers integrated on the
chip to route interrupts for the integrated
ohci(4) USB controller (which
appears as a separate PCI device).
NetBSD provides support for the following
devices:
- com(4)
- serial communications interface
- lpt(4)
- parallel port driver
The ssio
driver appeared in OpenBSD
4.2. It was ported to NetBSD 6.0 by Nick
Hudson.
