2.5.69-mm5: reverting i8259-shutdown.patch

2.5.69-mm5: reverting i8259-shutdown.patch

[Felipe Alfaro Solana]

Hi again, Andrew,

Besides the "make_KOBJ_NAME-match_BUS_ID_SIZE.patch" causing "pccard"
oopses, I've also found that, with 2.5.69-mm5 compiled with ACPI
support, my laptop is unable to power off. The kernel invokes
"acpi_power_off" and stays there forever.

I've found that reverting the "i8259-shutdown.patch" fixes the problem
and my laptop is able to shutdown properly (init 0) when using ACPI.

A hardware bug? A kernel bug?

Thanks!

And thanks again, again.

That's the below patch.  It looks pretty innocuous.  I'd be assuming that
there's something in the shutdown sequence which needs 8259 functionality
after the thing has been turned off.

This could well depend upon .config contents and linkage order.

Eric, maybe we need to turn it off by hand at the right time rather than
relying on driver model shutdown ordering?

Interesting. This is yet more proof that system-level devices cannot be
treated as common, everyday devices. Sure, it's nice to see them show up
in sysfs with little overhead, and very nice not to have to work about
them during shutdown or power transitions. But there are just too many
special cases (like getting the ordering right ;) that you have to worry
about.

So, what do we do with them?

Does the PIC shutdown callback get called _just_ before acpi_power_off?

It may or may not be. It depends on which order it gets registered in, 
which is arbitrary (*). One can enable DEBUG in drivers/base/power.c and 
crank up the console log level to see the order that devices get shutdown 
in on their system.

(*) - Ok, we can control the registration via link order, but that's 
something we'll be tweaking until our dying days in absence of a good 
solution.

The registration is somewhat unfair here, it depends on device_initcall 
and we initialise the 8259 in init_IRQ.

I'd say that as long as the shutdown routines are executed in reverse
order of startup, then the core driver stuff has fulfilled its
obligations.

In this case we need to understand why the lockup is happening - what
code is requiring 8259 services after the thing has been turned off?
Could be that the bug lies there.

Felipe, please send your .config.   (again - in fact you may as well do
cp .config ~/.signature)

Pat what do you say to some late shutdown callbacks? I'll drop you a 
patch sometime tommorrow.

OK, I've changed "#undef DEBUG" to "#define DEBUG" in
drivers/base/power.c, but during shutdown, I can see no extra debug
messages. What am I doing wrong?

Config attached...
Don't understand what do you mean with "cp .config ~/.signature" :-?

Bah. It would work, but it's a hack. We'll get caught in a game similar to 
the leap-frogging initcalls. In fact, we could just get really twisted and 
define various levels of exitcalls. [ Or, do them implicitly with some 
linkser-section-fu by calling the modules' exit functions in the reverse 
order in which they were initialized, but that's another story. ]

I just think that system level devices need to be treated specially in 
every case. They just don't work as normal devices because of the ordering 
issue. We can keep a separate list of them and deal with them explicitly 
after regular devices. It's not that bad of a change, but will take a few 
days, unless someone wants to take a stab at it..

Nothing. No one has shutdown methods in their drivers. This patch should 
give you a little more info. For me, it says the i8259 is getting shutdown 
very early in the process, which surely can't be good..

I guess shutdown needs to be treated like suspend, and needs to have
"level". There should be no shutdown, you should do suspend(5, ) and
go through all levels properly.

Unable to reproduce, appears to be machine specific, 1 laptop and 2 test

The machine is a NEC (Packard Bell) Chrom@. Could an lspci be of
interest?

Hmm perhaps /var/log/dmesg, also can you try this ugly patch?

With the previous patch applied, I can't make the kernel to printk
anything interesting after "Halting the computer". Now, I can't even see
the "acpi_power_off" message I was seen before.

Attached is "/var/log/dmesg" of a 2.5.69-mm6 kernel.
Thanks!
