this might be a daft question.......


what causes the power led to go out on the 712 systems ?

is it software controlled ?

I don't think so.
The power button is under software control but I think
the LED is wired to the power supply directly.

was just wondering - mine goes out after the system starts loading - flashes
before that

when it had hp-ux on it, it stayed on

another question...

is it possible to hook the power button to the shutdown command like it is
in hp-ux ?

Thanks

The LED and the powerswitch work as expected on my 712/80 at least since
the 0.9.3 ISO timeframe. I remember the LED was not working at some point
in the past, though,

I was testing a fresh install with 2.4.17-pa23 kernel last night on 712.
When I hit the power button it did a orderly shutdown and then powered
off.  Very nice.

It depends.
I know the power button works correctly on my c3000 and 715/64. Both
systems shuts down the computer cleanly.
But on another Apollo/50 machine (712/50 or 715/50 - I don't remember) 
pressing the power-button turns off the machine immediately. This is a bug
and should be fixed if possible.

We had the same problem here, and we solved it as follow:

When in Boot Admin, check the 'chassis' command.
We suppose that Chassis Codes must be turned 'on' so that the LED does 
not go out after booting.

The 715/50 Apollo has a hard wired power button, and a full array
of leds on the front to indicate power/heartbeat/rx-tx/disk access.

My 712/60 definatley has a soft button (since I routinely pull
the rear power plug when my "tinkering" causes a kernel crash), 
and the led stays on after booting.

Re: [parisc-linux] Power LED

[Christoph Plattner]

YES !!! The LED is software controlled !

I know, that my LED on the 712/60 flashed, as long as I am in
the PDC boot loader, after booting the OS, the LED stays on,
shutting down the switched off the LED.

I think the LED is normally controlled by the PDC LED control,
where RUN/WARNING/CAUTION/FATAL/.... can be defined, but on the
712 I never tried it. On the E55 I could control the LEDs in this
way, which is definitly different to the 720/730 and to the
machines with LCD.

Re: [parisc-linux] Power LED

[Christoph Plattner]

On the Apollo machine (720/50, 730, etc) the Power-Switch is NOT 
under software control. The switch is simple a "shortcut to ground"
and is a direct input line of the power supply unit (I know this,
because I have troubles with my power supply and studied the electrical
wirering, etc.).

On E55 I also think, that the switch is controlling the power supply
also, as I can switch off at any moment in Linux and HP-UX.

In the 712, the switch is definitly under software control, as the
software can simple ignore it ... and much more...

[parisc-linux] MySQL Server

[Tilo Jandt]

Hi,

I've got a problem whe installing the MySQL-server.
Last time when I updated my system with apt-get the MySQL Server should also
be updated but after downloading the File, extracting and preconfigurating
the update proces stopped after "Stopping Mysql-server".
I waited 2 hours but nothing happend. The MySQL couldn't be started and if I
remove the new mysql-server and install the old one with dpkg the same
procedure happens.
Every time after the preconfiguration the install hangs.

I don't know what to do. I cleaned up my system and wan't to new install
MySQL, but everytime the same procedure. Does anyone solved this problem or
does anyone have any idea?

Thanx,
Tilo

Re: [parisc-linux] MySQL Server

In case you have libc6-2.2.5 installed you might try
to downgrade to libc6-2.2.4-7 again. 
Could be worth a try...

the MySQL server never worked for me. With the old libc6, one thread keeps
looping (100% CPU time) and with the new one it simply hangs.

When I push the power-button on my 715/80, it prints a
message on the screen, that a shuwdown is requested,
and then shuts down immediatly. On the next start up a
fsck is required.
It seems to be software controlled, or it would not
print that message(I think).
Maybe a shutdown signal is emmited from the kernel at
one point, but the runlevel isn't changed before.
So it should be possible to isolate that signal and
use it seperately in the atx style.
(I'm not a kernel hacker, but maybe this is a starting
point?)
Just speculating.

715/64, 715/80 and 715/100 belong to the so-called
715/new machines and all of those support the soft-power
switch, else you wouldn't have received the 
"Shutdown requested..." message. 
In your case I assume, that your filesystems wasn't clean
before you did shutdown your system....

BTW, the shutdown is initiated by the kernel by sending
a SIGINT to the PID (cad_pid) of the init process. This
is done in the file power.c:
http://cvs.parisc-linux.org/linux/arch/parisc/kernel/power.c?rev=1.5&content-type=text/vnd.viewcvs-markup
After receiving this signal the init process switches the runlevel,
shuts down your system cleanly and runs /sbin/poweroff
or /sbin/halt. This is already the case and is also done
that way for ATX systems.

Helge

But if I push the power button, the init process
doesn't seem do change the runlevel, and power off
immediatly.
I can see the message "Shutdown requested..." and then
- power off -.
I think this souldn't be so.
Also I think it is a bit dangerous if everyone can
switch of the system, clean or unclean, just by
pushing the button.
Maybe a 5 second push-time would be good (like ATX)
but with a gracefull shutdown.
After all the halt script does not power off my
715/80.
I have to switch it off manually.

Yes, that's wrong. But you seem to be the only one
who has such problems with 715/new. As I said in another
mail my Scorpio (715/50) machine shuts down immediately too - 
but this machine doesn't support the soft-power switch either.
BTW, which kernel are you using ?

> Also I think it is a bit dangerous if everyone can

That's right, but that's also the behaviour on Non-ATX PC's.

> but with a gracefull shutdown.

That's not that easy.
On some systems the switch will send a key-down signal from
the first press on, independantly if you released the button again or
not. Other machines just send the signal while the button
is down and stops it again if it was released.

That said, this is how I wrote the code. 
In process_shutdown() you'll find:
       /* wait until the button was pressed for 1 second */
        if (shutdown_timer == HZ) {
                static char msg[] = "Shutting down...";
	    printk(KERN_INFO "%s\n", msg);

This means, that the kernel will just shutdown, if you pressed
the button for at least 1 second. You might change that to 5*HZ if
you want the 5 second push-time. 
But, as I said, the kernel can't recognize on some systems if
you have released the button again and so it will always 
time-out and initiate the shutdown request. Your 715/80 seems
to fall into this category of systems.

[parisc-linux] Power LED

[Hinrich Aue]

I use 2.4.17-pa26

I tried to increase push-time to 5*HZ.
But as you said, the machine doesn't seem to recognize
when I release the button. So the shutdown is
initiated correctly, but after 5 sec the machine shuts
down, ignoring whether the runlevel 6 is reached or
not.
BTW why does the halt command not shut down the
machine?
I heared it would work. :-<
Is it possible to change the bit 0 if CPU diagnose
register 25 by hand?

Yep.

process_shutdown() calls after 5 seconds poweroff(), which in
turn calls deferred_poweroff() again. deferred_poweroff() then
sends the SIGINT signal to the init process which then
initiates the normal shutdown. There is no other kernel-code
which powers off your computer directly.
This works perfectly for me on the 715/64 and many others here.
Maybe your PDC (BIOS/Firmware) handles that differentlly ? Maybe
you could verify that you have the most recent PDC version ?

> BTW why does the halt command not shut down the
> machine?

I've not found any direct PDC (BIOS/Firmware) call which does this.
pdc_soft_power_shutdown() doesn't seem to do want it's name
suggests. It instead seems to set a flag in the PDC so that when 
you reboot your system it will shut off during the main PDC tests. 
So there seems to be a way to turn off the system immediately,
but it seem to be _very_ system dependant too.

> I heared it would work. :-<

I tried it, but it didn't worked.
If we would find a way to reset bit 0 in reg 25 we would
have a solution.

playing mp3s on my 712/60 works fine with xmms and mpg123, the cpu is
powerful enough to handle mp3 decoding.

Yes. You need the harmony driver, which was recently added to defconfig and 
should be in recent pre-build kernels ftp site and kernel-image packages in 
the Debian archive.

You need to enable CONFIG_SOUND_HARMONY in the kernel config when you build a 
kernel. If you're using a prebuilt kernel from the ftp site the tarball 
contains the config file it was built with. If you are using

ftp://ftp.parisc-linux.org/kernels/32/32-2.4.17-pa27.tar.gz

that kernel contains the harmony driver and it should just work. I've used 
xmms and mpg321 and they work great.

Good luck,
