[parisc-linux] GSC cards

[Philipp Rumpf]

Hi,
even if there was not much list traffic in the last weeks, development is
going on and even making real progress.  We expect to run our first user
space program RSN.

One of the areas we now have code for is GSC bus walking.  This code is
basically engineered from some hints in the Dino documentation and not
tested with any other device (Lasi, Artist, and the CPU, though on the
GSC bus, do not use the HPA pages and are not auto-detectable in the
same way as Dino.

Therefore, if any of you have access to other machines than 712's or 
A180[c]s (this includes 715s), or machines with GSC cards other than
Dino-on-a-card based ones in them, please try to boot them with the Image
at ftp://sunsite.auc.dk/pub/os/linux/parisc/testing/image-2.2.1-gsctest
and send the lines between "GSC init" and "mem_init bla bla bla" here
(it might be a good idea to keep the subject line "Re: GSC cards" instead
to avoid annoying anybody).

TIA,

	Philipp Rumpf

Rather than depend on just one implementation, look at the PA I/O
Architecture documents. Dino is an implementation of a PA I/O device.
BTW, GSC and HP-PB bus walk are basically the same - both follow PA
I/O architecture.

AFAIK, these documents are not publically available.  If they indeed are,
could someone send the URLs ?

What you need are the early chapters of the I/O Architecture Reference.  You're
right that these have not (yet) been released by HP, but I've just started the
process to get these chapters released to you.

Apologies - I thought the entire PA I/O Arch reference was available.
Given most of the platform stuff (Lasi/Dino/PA 1.1) has been released,
I didn't realize PA I/O Architecture Reference would contain anything
HP wanted to keep internal.
