[gentoo-dev] ACPI in gentoo

[gentoo-dev] ACPI in gentoo

[Gertjan]

Hi,

I use the gentoo-sources kernel on my ASUS L3400D laptop. I would like to
get suspend to RAM working... When I execute "echo 3 > /proc/acpi/sleep"
nothing happens. Sleep states 1 and 5 work perfectly. I would like to know
if somebody can help me with this. Also, I would like to know what version
of the ACPI4Linux patch is included with gentoo-sources, or at least where
I can find that version.

Actually, I don't even know if suspend is already supported in the
kernel... Maybe this is the wrong place to ask these questions, but I
first want to know what version of the ACPI patch is in the Gentoo kernel,
before I inquire at the ACPI mailing lists. Hopefully there are people on
this list that can answer my other questions too.

Gertjan

No surprise:-) In 2.4 kernels S States aren't officially supported. Wait until the 2.6 kernels..
Perhaps there are some backports..

Yep, I think it is...

See @ acpi-mail-archive on sf. A lot people asked already the same questions...

Do you know if ACPI S states are already supported in the 2.5 kernels? I
had a laptop with APM support and I loved the suspend feature. So I really
am looking forward using it again.

Yeah, I already browsed there, but I was wondering if the latest patches
are applied to the gentoo kernels too? That's why I turned to this mailing
list.

I'm sorry, I'll check the ACPI mailing lists.

be careful! ACPI is typically not fully implemented in the available
hardware. so trying a sleep-state may cause your system to crash both
because of kernel or hardware problems! and it's _very_ difficult to
find out who's to blame! with my sony-vaio S3 causes the system to
freeze to death immediately .. to, the kernel seems to support the
function, since something happens ;)

anyway, acpi will most likely be "fully" implemented in the 2.6 kernel -
then you will have a real chance to find out, what your hardware is
capable of :)

cat /proc/acpi/info should tell you what version it's using.

There's also the acpi-sources ebuild that has newer acpi patches.  It's 
a little behind at the moment, I think it has a December release.  I had 
  to modify it to pull in the latest acpi patch.  lolo-sources usually 
has newer acpi too.  It might work for you.

Brandon, if you're listening, acpi-sources needs to be version bumped.
I changed these variables:
ACPI_PATCH="acpi-20030218-2.4.21-pre4.diff.gz"
KERN_PATCH="patch-2.4.21-pre4.bz2"

and uncommented the KERN_PATCH bits later in the ebuild.
