ACPI update

Contributed by marco on 2006-10-12 from the acpi-r-us-AGAIN dept.

After many hours of hacking all over the world Jordan has rewritten the ACPI parser and evaluator once more to fix some serious memory leaking issues. Today we committed the latest instalment of ACPI into the tree. My laptop, a Dell D810, now runs ACPI happily and detects insertions and removals of batteries and power supplies. It also reacts to pushing the power button by powering off.

All that said, we need some serious testing. Please test ACPI by applying this diff (i386):

Please report success or failure to jordan@ and marco@.

If you run into issues send us a dmesg and a dsdt dump. Create a dsdt dump by running the following command: "acpidump -o foo.dsdt" and replace foo with a useful description of your system (ex: dell_d810.dsdt).

Congratulations guys! That's a very good job :)

I love when the power button works!

My laptop has a buggy pcibios which prevents the inbuilt intel wireless card from working (I get memory locking errors). The card works fine under linux with ACPI enabled. Is this update likely to allow me to finally get the card working under OpenBSD or should I keep being patient?
Thanks

  acpi only works on i386 and amd64. and by 'works' I mean "its only in the bios for those archs".

Is there any way I can switch off screen when lid button is pressed on ACPI enabled kernel. Can I somehow read status of ACPI buttons?

Does this mean there is support for ACPI version 2?

now, the latest commits to the acpi code breaks out the kernel.
