sony-laptop for acpi-test

Hi Len,

here is a first submission with some of the backlog I accumulated in these months.
The target is 2.6.29.

Thanks

Creating Type4 was a mistake in the first place. Some users report that also Type3 vaios require the same extra hotkey handling which the Type4 for was menat to guard from.
Merging down Type4 into Type3 will just remove a useless distinction.

This laptop has 5 SPIC managed buttons above the keyboard:
sound + and - as well as brightness, zoom and S1. Possibly the entire VGN-A serie behaves the same.

Sony laptops have a single hardware rfkill switch, which controls several wireless devices: wifi, bluetooth, wwan. The code to selectively control bluetooth and wwan is already present. This patch adds handling of wifi.

Please don't add more custom radio control switches. It'd be better to add rfkill support. Otherwise we have even more stuff in /sys to carry around for ages before deprecating.

Matthew Garrett | [email protected]

My Vaio VGN-TX770P has ipw2200, which IIUC understands hardware rfkill switch state. At the same time, when there is no wifi network around and I am on internal GRPS modem link, I would like global switch to be on, but wifi to be off. The main reason is to save power. The device has a dedicated key combination for this, on which Windows drivers by Sony operates.

Do you mean that the patch should use some other file instead of /sys/devices/platform/sony-laptop/wifipower for input/output?

If so, could you please provide some pointers on what should be done, and where in the source tree to look for references?

Cheers,
Sergey Yanovich

Yes. It should register an rfkill device, which will then be exposed via /sys/class/rfkill. Checkout out Documentation/rfkill.txt.

Matthew Garrett | [email protected]

In patch [PATCH 1/7] [sony-laptop] merge Type4 into Type3,
type 3 and type 4 spic models are merged, and type 5 model I added (of cause It is not problem, it is completly same as type 4) are dropped.

So I think spic_types[4] is invalid. This line should be as
bellow (Use Type 3 on ICH9_1 machines):

  dev->control = &spic_types[2];

gosh!
/me looks for his emergency brown paperbag

Len,
I'll resend the patchset in the next days, I'll also see if I can rework the rfkill one to use the proper subsystem.

thanks

Hi Mattia,

I tried your patches on top of 2.6.28-rc3 and the tests showed:
- backlight is working via sys interface and xbacklight
- hardkeys are still not working
- wifipower, wwanpower, bluetoothpower sys files do not work

All on Sony Vaio VGN-Z11

Best wishes

--- Douglas Adams, The Meaning of Liff

Hi, thanks for testing.

what do you mean? some Fn backlight button (F5/F6 usually) or a separate button?
Can you see if the kernel driver reports the events (pressing releasing keys) but loading it with debug=1 ?
If it does it's just a matter for you to configure acpid or hal to behave as you expect.

can you send the kernel output after loading sony-laptop with debug=1 and echoing some value to those files?

thanks

mattia
:wq!

Hi Mattia,

F5 and F6 does not work. No message of events in the kernel log.

Nothing.

I did load with debug=1 and

# pwd
/sys/devices/platform/sony-laptop
# cat wifipower 
0
# echo 1 >wifipower 
# cat wifipower 
1
# cat wwanpower 
0
# echo 1 >wwanpower 
# cat wwanpower 
1
# cat bluetoothpower 
255
# echo 1 > bluetoothpower 
# cat bluetoothpower 
1

Output of dmesg starting from loading the sony-laptop module is attached.

If you need more tests just let me know, I can patch/hack things into the sony-laptop if you need it.

Best wishes

Norbert
