I'm somewhat interested in getting some of the APM stuff working
on my laptop, which is a Compaq Concerto. It's a little old, so
if this just isn't going to happen, it's no big deal.
On the off chance that any of these observations help advance the
cause, I'm sending them. Feel free to ignore all of this -- I'm
just tinkering for the fun of it.
There's a couple things I'll mention. First, I've got two PCMCIA
cards in it, and they both work fine. One's an Intel Faxmodem
14.4, and the other is a Linksys Ethernet card. (Don't buy these,
by the way -- the dongle for the ethernet connection is loose and
fragile. I'm on my second dongle, and they're not cheap.)
Nate, you mentioned a while back that some people have to use sio.c
with some of the probes commented out to get the modem card to
work. I'm one of them. So, if anyone wants to run that issue
down, I'd be happy to try your code. Since it works with the probes
(3, 5 and 6, if I recall correctly) commented out, I'm happy with
it the way it is. I might look at it after I get around the APM
things.
First of all, here's the output from apm. Is that APM version
possible?? Maybe I'm too far back on this old machine to be able
to get this stuff working.
APM version: 0.27
APM Managment: Enabled
AC Line status: on-line
Battery status: charging
Remaining battery life: 100%
Next, here's the boot output from a kernel with APM_DEBUG defined.
The thing that I think might be useful for people working on the
APM stuff is the part where "Add hook" is called for BOTH Cirrus Logic
and Intel PCIC hardware. Is this right? It doesn't look right.
Plus, both are in there multiple times.
Oh, I suppose I should mention what doesn't work: if I do a
"zzz", I get a panic. The stack trace from DDB has a zillion
calls to "apm_processevent" and "apm_suspend" -- as if they're
calling each other in an infinite loop. Interestingly, the
machine DID suspend right after the debugger prompt
comes up -- so it's almost like the suspend would work if the
routines weren't calling each other to death. Resuming from
suspend brings it back up with the debugger active, so the resume
almost seems to work, too.
If this helps anyone trying to get the APM stuff working in
a general fashion, great. If not, I'll just continue to
poke at it myself.
