Real Time UNIX

[Dave Decot]

Hewlett-Packard offers a broad range of technical systems which run HP-UX, a
version of UNIX conforming to Version 3 of AT&T's System V Verification Suite
(SVVS) that verifies conformance to the System V Interface Definition (SVID).

HP-UX also includes most of the important 4.2BSD features (such as vi, csh,
Berkeley-based kernel and fast file system, job control, rlogin, rcp,
ARPA networking (TCP/IP), sockets), many defacto standards (such as NFS,
ksh, kermit, etc.), plus many HP enhancements.

The HP enhancements for real-time include the following:

	Non-degrading process priorities
	Kernel is pre-emptable by high-priority user processes
	Virtual, real, and user interval timers
	Reliable signal mechanism based on that of 4.2BSD
	Multiplexed I/O arbitration based on that in 4.2BSD
	Locking of processes or parts of processes in physical memory
	Pre-allocation of disc space for important files
