In this case, would a patch ripping off asus_acpi, ibm_acpi and
toshiba_acpi  from the kernel be accepted ?

I don't really care much about sony_acpi (since I'm not maintaining it
anymore, even if I still answer support requests about it), but this is
just silly. This has been going on for more than one and a half year now.

Meanwhile (at least from what I've seen), the ACPI subsystem still doesn't
provide this "generic" API which platform specific driver need to
implement. drivers/acpi/{hotkey.c,video.c} are just rudimentary, and there
is no indication that this is going forward:

hotkey.c was expected to replace all platform specific driver under
acpi directory, and I have ever expected that ACPI spec would define
standard device ID, and AML method name and event number for common keys
such as brightness control, output switch. So, I was expecting the hotkey.c
could become the generic driver when such spec was published and accepted
by OEMs. But, I don't know if such kind of things will happen.

So, if there are NO standards, and we don't want mess up user space tools with
a dozen of totally different acpi proc interface for different platform 
drivers. We have to use  generic code to create  unified interface for the 
sake of clean user space tool.  Some technique are:
1. use input layer to translate any hot-key event into key code defined in 
input.h
2. use backlight class (driver/video/backlight.c)  to hook generic brightness 
control interface for brightness control under sysfs. 
3. use output class to hook generic output switch control interface for 
display output switch control under sysfs.
4. other generic code.

I think the maintainer of asus_acpi, toshiba_acpi, ibm_acpi, sony_acpi, 
panasonic_acpi, msi_acpi, ... should use the techniques mentioned above.
for new platform, Please don't just fork a new driver from toshiba_acpi.c, or
the existing ones in drivers/acpi. They also need to use  generic code 
mentioned above.   Then, the platform specific driver could be accepted into 
mainline. Otherwise, I don't know how these kind of platform specific driver
can be maintained, and deployed by OSV.

You are right.  And the reason is that platform specific drivers are not part of ACPI.
They must either be vendor documented/supplied or reverse-engineered.
Vendors have not been forthcoming with documentation or code to support
Linux laptops, and our happy team here at Intel is not allowed to be in
the reverse enginering business.

So I concur that hotkey.c is a failed experiment, and I'm going to delete it.
There is more different than common on these boxes, so it makes no sense.

video.c, however, is standard, and stays for those machines that actually
do follow the public specification.

Still true, though it is clear we'll never be able to delete platform specific parts --
just the parts that duplicate the generic standard functions..

How about 2.6.21?
What needs to happen is
1. a maintainer for sony_acpi.c needs to step forward
    I can't do this, I'm not allowed to be in the reverse engineering business.

2. /proc/acpi/sony API needs to be deleted

3. source needs to move out of drivers/acpi, and into drivers/misc along with msi.

Luming has a sony laptop and can help with this, but
he can't be the permanent maintainer any more than I can, for the same reason.
If we can get past #1, then I recommend we apply the patch series in -mm to
the acpi-test tree and go from there.

Well, I can't do this either, because I just don't have the required
hardware anymore.

If someone want to step forward now it is a great time !

Sensible suggestions, the new maintainer will have to work on this.

I have the hw and I'd be happy to do some basic working on the code
but:
- I'll probably need some help;
- I'll have an almost-blackout between the end of February and the end
  of April as I'm moving to a different country and I'll need some time
  before I can be active again (I hope I'll have at least easy mail
  access for all the time though).
Anyway if it is still ok I can maintain the thing, to months seems
enough to give the driver a shape.

And turn extra-backlight features into platform_device stuff? So 2 and 3
can come together.

Moreover, I own an SZ72B and an older GR7 and have come to the same
findings of Cacy, plus a patch to allow a smarter "debug" mode.
So, how to proceed? (I've just cloned the linux-acpi-2.6 tree)

Thanks Len, Thanks Stelian

I have a VGN-something-or-other notebook and I use this driver regularly.

The place to start (please) is the patches in -mm:

2.6-sony_acpi4.patch
sony_apci-resume.patch
sony_apci-resume-fix.patch
acpi-add-backlight-support-to-the-sony_acpi.patch
acpi-add-backlight-support-to-the-sony_acpi-v2.patch
video-sysfs-support-take-2-add-dev-argument-for-backlight_device_register-sony_acpi-fix.patch

It presently has both the /proc and /sys/.../backlight/.. interfaces, so the first
job would be to chop out the /proc stuff.

Ok, I'll import all of them and start from there.
Is it ok to wipe all the /proc stuff without notice?

spose so.  I don't know if any apps are dependent upon the /proc file,
but the driver isn't in mainline yet so it's unlikely that there's a
mountain of software depending upon existing interfaces.

Not a mountain, but still a few applications support that interface.

At least the powersave daemon 'powersaved' and HAL support the
brightness interface of the Sony driver.

The responsible developers are following the linux-acpi list.

Well, HAL has used it for changing the brightness for the last year or
so: /proc/acpi/sony/brightness

Although if you use a new enough HAL (CVS), the laptop will be supported
via the shiny new backlight class.

great, -mm already has the /sys/class/backlight in place for sony_acpi
and I suppose the /proc entry can be kept until 2.6.20 is released, i.e.
just before pushing things for .21.

Len, would you allow it?

Well, I am the current "maintainer" for this and it has probably been a
year since I left Sony's laptop world, so I guess it won't make much
difference if you're not very active for a month or two :)

:)

Well, it seems that on some Vaios (including Nilton's pcg-frv26 but not
only this one), the Fn key events aren't seen by sonypi or sony_acpi
GHKE method, but do generate an ACPI notify event.

For those laptops, the patch forwards the ACPI event to the ACPI system
and can be later interpreted in userspace using
acpid's /etc/acpi/default.sh (example directly from Nilton):

Is this safe? I would not want normal users to poke on that.

Hi,

  I own a Sony Vaio VGN-SZ340 and I had problems regarding acpi + it's
dual core processor. The guys from Intel gave me a workaround and now
it recognises both cores.

  The problem is that it does not do cpu frequency scaling for both
cores, just for cpu0...And when I boot with acpi the Nvidia graphic
card doesnt work also.

  I don't know if you know about these problems regarding sony acpi.
The guys from Intel said that this notebook have 2 dst's. So to detect
both cores the workaround just uses the second dst (although frequency
scaling does work for both.)

  I can help you to fix this bug...I have the machine where we can do
some tests..


Best regards,

Hmmm, seconded. It also seems quite a gratuitous change and I have a
different patch that takes care of permissions and the /proc stuff is
going away in any case.

Oh, sorry, I'll try again :)

There are several ways of detecting the Fn key events, depending on the
Vaio series:
	- some Vaios report them using the SPIC device (driven by sonypi)
	- some Vaios let the driver poll for the Fn key status using the GHKE
ACPI method of the SNC device (driven by sony_acpi)
	- some Vaios generate an ACPI notify event on the SNC device when a Fn
key is pressed - this is what the latest patch is for.

Unfortunately there are way too many different Vaio series, and no
information about what series support what method. I should have
maintained some sort of wiki to let the users build themselves a
comprehensive list, but I never get around to do it. Maybe Mattia could
do it if he has the time and will...

Well, there was an /etc/acpi/default.sh in an older version of acpid...
I'm not sure what it looks like now on a recent Fedora but on my Ubuntu
I still have an acpid package, which has some files in /etc/acpi/
looking familiar.

Well, you got the events from evdev, which means you probably got them
directly from sonypi (or the regular keyboard..)

Unless your distribution does some neat tricks and somehow feeds the
events coming from somewhere into the event subsystem (like Ubuntu's
acpi_fakekey for example...).

FYI, sonypi is also searching for a new maintainer, and it is quite
closely related to sony_acpi...

Yes, probably the FnKeys stuff needs to worked out into a single driver
to ease it usage (I still remember some very old discussion about making
sonypi use the acpi methods to access the hw).

Let's see if I can come up with something, I have also an ux50 that is
not very happy with current sonypi

Feel free to contact me for testing on U3.
FnKey is done through sonypi here, if I unload it, `showkey` does not give
keycodes for them anymore.

Sure, no problem.
Checking it into my tree with /proc/acpi/sony is
no different than what is in -mm today.

When we push upstream, however, the /proc/acpi/sony part should be gone,
or at least scheduled for removal.

I suggest a sub CONFIG option under CONFIG_SONY_ACPI, say,
CONFIG_SONY_ACPI_PROCFS so you can #ifdef the code that
is going away.

thanks for stepping forward Mattia,

The frequency scaling issue sounds like a BIOS/Linux incompatibility.
Please open a bugzilla, if you haven't already, and include the
output from acpidump.

The nvidia issue sounds like an interrupt issue, so please reproduce
it using the open source nvidia driver (not the nvidia binary),
and include the lspci -vv output, dmesg, and /proc/interrupts.

  I agree that it sound like a BIOS/Linux incompatibility. You can
find my acpidump and DSDT inside the link above. That bug is still
opened.

I'd rather avoid pushing mainline something already scheduled for
removal. Also, a workaround can eventually be implemented in the
userspace tools using /proc/acpi/sony

Ah yes, the duplicate MADT issue is clearly a BIOS bug.
It is possible that we can tweak our Linux workaround for it to be more
Microsoft Windows Bug Compatbile(TM).

It looks like this issue results from that above,
rather than being an additional problem.

If interrupts fail using the open source nvidia driver, (and using the workaround
from the bug above to use the right MADT, please open a new bug report
as I think it would be an independent issue.

Maybe Windows discovers processors using the namespace rather
than the MADT.

Nod.

Based on the fact that the 1st MADT on this box is toast, they're not using that.
If the last one also doesn't work universally, then they must be using the namespace.

For us to do the same would be a relatively significant change -- as it means
we either have to push SMP startup after the interpreter init, or move the
interpreter init yet sooner.

In general, over the last couple of years, we've been forced for compatibility
with various systems to move ACPI initialization sooner and sooner.
(I think the last issue was getting the HW into "ACPI mode" sooner
 because some stuff I don't recall didn't work if we didn't)
It would probably make sense to experiment with what the soonest we
can initialize ACPI, as I have a feeling we're going to have to head that way.

If any of the two tables does not work, may be we need both together?

Yes, the idea of generic code and sysfs things can
remove the supportable issues as to complete different
user interface exposed in /proc/acpi/ by different
platform specific drivers such as ibm_acpi.c,
asus_acpi.c, and toshiba_acpi.c,....

Please take a look at drivers/video/backlight..
And here is a example to use backlight class for acpi video driver:
http://marc.theaimsgroup.com/?l=linux-acpi&m=115574087203605&w=2

Please let me know if you have any other ideas to consolidate the
platform specific drivers such as ibm_acpi.c ,asus_acpi.c, toshiba_acpi.c
panasonic_acpi.c, sony_acpi.c , msi s270.c .....

Thanks,
Luming

well, for us, users/owners of newest vaio, there's no choice. with default
brightness it's impossibile, really impossibile, to read even the
characters of the console, in daylight.

having sex at all?".

Is there a such example code under kernel now, so one could look at it and fix 
sony_acpi driver.

Nope, not as it is.  Useful != supportable.

1. It must not create any files under /proc/acpi
    This is creating a machine-specific API, which
    is exactly what we don't want  Nobody can maintain
    50 machine specific APIs.

    These objects must appear generic and under sysfs
    as if acpi were not involved in providing them.

2. its source code shall not live in drivers/acpi
    it is not part of the ACPI implementation after all --
    it is a platform specific driver.

With 2.6.18-mm1 it works fine.

Will sony_acpi ever make it to the mainline? Its very useful for new Vaio 
models.

/proc/acpi/sony comes from the sony_acpi driver, not sonypi.

You should get the latest sony_acpi driver, preferably from the -mm tree 
which hosts the most up to date version.

Hi,
	I've got a Sony Vaio VGN-SZ1VP (dmidecode[1] and lspci[2]).
	Using default kernel (linux-image-2.6.15-27-686) of Ubuntu
	Dapper I've got /proc/acpi/sony/brightness and it works well
	(yes, Ubuntu drivers/char/sonypi.c is patched).
	With any other newer vanilla kernel, 2.6.15/16/17/18, /proc/acpi/sony
	doesn't appear, and it's impossibile to set brigthness, of
	course. Same thing with Ubuntu kernel package
	(linux-image-2.6.17-9-386).
	I tried to port Ubuntu sonypi.c patches to 2.6.18, but it doesn't
	work (I mean, it compiles clean, it "modprobes"[3] clean, but no
	/proc/acpi/sony/ directory).

Thanks a lot for your time and work,
