WAX research
I've spent some time trying to evaluate what it would be like to get WAX support into Linux, and have nothing new to report.
Why this mail? Because I actually dug through some code and thought I'd mail it here so it'd get archived and because maybe someone here has something to add.
HP hasn't released docs on WAX and I can see why. WAX hasn't been used in ages (the latest one is probably the D270, but they are in all 715s), and finding the docs is probably hard.
So... alternative information that's a bit hard to find...
1. OpenBSD
There is some mention of WAX in here, but it's ancient. Maybe I'm not looking at the latest version, it is stamped with
/* $OpenBSD: wax.c,v 1.1 1998/11/23 03:04:10 mickey Exp $ */
The file in question is src/sys/arch/hppa/dev/wax.c. You can get download instructions from http://www.openbsd.org/hppa.html .
That version of wax.c just has some WAX detection code, although we know how to do that already.
2. Mach4/Lites
You can get this code from flux.cs.utah.edu/ftp://flux/mach/ALPHA/pa-snapshot2.tar.gz
I had actually thought that these guys had seen WAX code under NDA, but the docs say that wax is unsupported. The code for wax in usr/src/mach4/mach4-parisc/kernel/hpsgc/busconf.c looks like the code for asp with the variables replaced. It looks like this is a dead end too.
Mach4 actually also has some viper and ASP code that might be helpful.
If anyone has any corrections on any of this, or anything else to add, let me know. If there's some public info to go on, it'd enable someone to actually build up WAX support.
