that was what i wrote it on originally (wrote is a little strong; it's
basically philb's hil driver from linux/m68k).  however, i haven't tested
it recently (eg since we moved to 2.3).

[parisc-linux] HIL support on 715/old ?

[Chris Snow]

Has anyone tested the HIL support on 715/old [33,50] ?  We are seeing
hangs here and I was wondering if that might be the problem ...

We'll try to narrow down the problem.  Any "it is broken" or "you are
dumb, it works fine!" messages are appreciated :)

alright, well I'll do some more testing on it.  Probably not until after
OLS though (ie: next week)...

As I wrote earlier to this list ( see
http://puffin.external.hp.com/mailing-lists/parisc-linux/2000/06-Jun/0018.html
) the linux-2.3-pre8 is not able to boot on a 715/old.
It hangs during the initialization of the ASP chip. So
I guess that HIL (which depends on ASP) is not working
right now either.

Tara Dear had a similiar problem on a 715/50. So I
suspect that this is not a problem related to my
715/33 or my build environment.

I haven't had the time yet to look at the code, which
I really honestly truthfully do hope to work on :-),
but someone at some point fixed it for the 715/64,
which meant changing HIL_BASE.  Someone else mentioned
that there's no PCIish bus/device tree yet, so maybe they j
ust re#defined it rather than probing.  The 715/64 used to 
hang there and it was because the HIL_BASE was wrong.

It is the parallell port. I had the same problem last week. I have not
looked in to why, I just disabled it in .config

That would be great.
Since I'm moving to a new town, I won't have time in the next 2-3 weeks.

Yes, that was me. In the current code HILBASE refers to the variable hil_base
from drivers/gsc/hil.c. The address of the HIL-controller is
automatically set there by the detection routines.

No. The base-address is taken from the parisc-hw-tree. But maybe the choosen
interrupt-line is wrong for 715/old.
The HIL-bus itself has no PCIish tree (I mean: a list of the attached 
devices) yet.

Hmmm. ?
My 715/64 used to work with HIL-keyboard (keys come through, but the
translataion was wrong), but I haven't tested it in the last few weeks.

actually, the hang happens during parport initialization, when it tests
for ps2 (bi-directional) support.

It works fine without parport support.

Thanks for the tip. Now the kernel boots until the
sash prompt.
