Please describe the issues you have.
Fixing in DSDT is not a decent way.

Thanks

Re: sony vaio pcg-k45 hell

[Thom Cherryhomes]

well, to start:

(1) battery meter most of the time shows zero
(2) I get maybe 1 hour battery time.
(3) S3 suspend does NOT work at all (using hibernate-ram script)
(4) i get unusual time readings that seem to keep incrementing when
the battery is charging (when I DO see the battery meter)
(5) no fan control
(6) display does not dim when disconnected.
(7) hotkeys for changing brightness etc do not work.

arrggghhhhh

I tried to find a PSS table in the DSDT, and couldn't.. it seems the
acpi on this laptop is insanely broken. :-(

Hi,

Just to recall my experience with a vaio vgn-fs115b running
SUSE 10.0:

cpufreq active? This has not much to do with ACPI, though.

Probably not a general ACPI problem. Read Documentation/power/video.txt

sony crap bios, no ACPI fan control methods => not an ACPI problem

you need Stelian Pop's sony_acpi module for that (and a mechanism to adjust
the brightness on ac adapter plug/unplug, powersaved does this on SUSE).
It might also work with the generic_hotkey module, but i could not figure
out how to do it (i remember posts on acpi-devel that claimed that all
vendor specific acpi drivers are obsoleted by generic_hotkey, still have
to find out how to control the brightness of my panasonic with it).

> (7) hotkeys for changing brightness etc do not work.

SONY crap. These are no ACPI hotkeys, all the hotkeys on the vgn-fs115
emitted a standard keycode. Unfortunately all emitted the same keycode.

> arrggghhhhh

SONY notebooks are just badly designed IMO, even the Windows XP drivers
and utilities looked and felt very hackish.
Although the hardware / case / display / keyboard were fine, i would
probably not buy a SONY if i had to pay it with my own money.

Most of the problems you have are probably not ACPI problems.

There are lots of laptops where you will never get S3 working anyway
(e.g. Dell Inspiron 4150).

Try swsusp instead.

Most laptops have no fan control using ACPI, sometimes using SMI.

It probably works as on most laptops, the special keystrokes are handled
by the keyboard controller itself, so you'll never be able to
catch/control them from a user app.

Please note that almost all laptops are built by two or three factories.
I am willing to bet a large sum of money that Sony does not build them
themselves.

Also ACPI implementation itself on most laptops seems to be more or less
broken...

Some progress are made on generic_hotkey driver.  There is an example of
leverage generic_hotkey driver for sony laptop.

Please post acpidump output for vgn-fs115, Let me check if there are any
ACPI hotkey support.

i have the same.

no, no acpi interrups for hotkeys :-(

I'm trying this out but may only get to it on monday or tuesday next week.

ACPI generic hotkey working on SONY (was: sony vaio pcg-k45 hell)

setting brightness works on the vgn-f115b with the patch after fixing it up
for 2.6.14.2 (attached, the most nasty one was the missing
EXPORT_SYMBOL(acpi_scan_ids) :-)

I have of course some other questions:
- what will happen on other machines if i load the hotkey module and issue
  echo "10001:1:1:0" >/proc/acpi/hotkey/action
  - will it crash?
  - will it just not work?
  - will it just work, so this is a generic solution?
- will it also work on my panasonic which right now needs pcc_acpi?
  (i will check this one out soon)
- if the "10001:1:1:0" is not a generic string for all machines (i am afraid
  it isn't), how do i find out what to put into /proc/acpi/hotkey/action?

Another problem is that for distributions to be able to use this stuff, it
must not depend on the "acpi_generic_hotkey=1" parameter. Can't we decide at
module load time if we want to use the generic or the vendor specific hotkey
interface?
Having the user select which machine he has _before_ installing with some
cryptic boot parameter is something i'd like to avoid.

Also i see that now some sony-specific stuff is in the generic hotkey driver.
Will we have to add specific stuff for all other vendor specific drivers if
we want to merge their functionality into hotkey.c?

To be honest, the generic hotkey driver seems to be something of a nasty 
hack. It effectively exposes large parts of ACPI to userspace, but with 
a very limited API and various artificial limitations. Is there any 
reason why we don't shift to dev_acpi 
(http://free.linux.hp.com/~awilliam/acpi/dev_acpi/) and have a userspace 
application dealing with hotkey events? It would seem to be much more 
flexible.

I won't argue against this. However, i stopped hoping to get all the drivers
i need included into the kernel, so i will concentrate on getting all 
machines working with the generic hotkey driver and include this support
in powersaved. Unfortunately, i am totally AML illiterate, so all i can
do is provide DSDTs and test any instructions given to me :-)

This would be fine with me also, i do not really care what i have to do to
get this hotkey events, as long as i can get them :-)
