Hi,

This is the first public release of my ACPI driver for IBM ThinkPad laptops. The features currently supported are:

- hot keys (Fn key combinations)
- docking and undocking
- some basic fan speed control

Note that I've only tested on a ThinkPad X40 with the X4 UltraBase. I suspect many other recent models are sufficiently similar to work with this driver but I have no such reports yet.

I'll release this on the linux-thinkpad list as well, but I thought I'd get some comments here first. This is my first foray into the ACPI code, so do let me know if I'm doing something horribly wrong. :-)

(Sorry, no web page yet. One thing at a time.)

Thanks,
Boris

Ok, I've a IBM ThinkPad R32 but no docking station, so I can't test it.

Good for you :-). Do they generate ACPI events or do they just do the right thing? On the X40, Fn-F4 generates button/sleep, Fn-F7 switches to external display by itself, the other keys do nothing.

Same here, I've never used the Fn-F3 and Fn-F12 thing cause I don't need them ..... wait, F3 and F12 are also not workin... :-( But the keys for dimming the display (on a german Keyboard Fn-Pos1 and Fn-Ende and for this cool little led-light Fn-Bild^ are working without a problem and this are the usual buttons I use..... so keep on hacking

ps: if there is some time I'll test the patch... (then F3 and F12 should also generate acpi events??)

It (unsurprisingly) works well on my X40. I've added a script to use the video switch to call i855switch (i810crt works badly on the X40). I'm entertained to see that you're using the same workaround as me for video corruption after closing the lid :)

Hi Boris,

On a T41 it inserts in the kernel only if I replace _SB.GDCK with _SB.PCI0.PCI1.DOCK.
If I don't, I get the following message:
insmod ./ibm_acpi.ko
insmod: error inserting './ibm_acpi.ko': -1 No such device

and in dmesg I found:
ibm_acpi: acpi_get_handle(\_SB.GDCK) failed

At a fist glance, hot-keys work, but the Fn-F5 does not enable bluetooth anymore.
I will get back with more feedback.

Thanks,
Paul

Hi Boris,

Some more feedback from my T41.
First, the environment:
Fedora Core 2, Kernel 2.6.8-rc2 vanilla with acpica-20040715 patch. This is the first version of kernel and acpi that does s3 suspend to ram reliably on my T41. If you want my dsdt, just tell me and I will send you privately, because PAN is not able to attach anything to news posts. (maybe is not even possible).

now:
cd /proc/acpi/ibm
cat fan

current:        -1 -1 -1
preset1:        3000 3720 4410
preset2:        3120 3520 3800
preset3:        3120 3520 3800
commands:       <low> <medium> <high>, preset1, preset2, preset3

and i found this in dmesg:
ibm_acpi: acpi_invokef(FAN9, d, ...) failed
ibm_acpi: acpi_invokef(FANB, d, ...) failed
ibm_acpi: acpi_invokef(FAND, d, ...) failed
ibm_acpi: acpi_invokef(FAN9, d, ...) failed
ibm_acpi: acpi_invokef(FANB, d, ...) failed
ibm_acpi: acpi_invokef(FAND, d, ...) failed

if I echo preset1 > fan, I got this in dmesg:

ibm_acpi: acpi_invokef(FANS, vddd, ...) failed
ibm_acpi: FANS(3000, 3720, 4410) failed

As for docking, I don't have the dock right now, but I'll test it some other time.

The hotkey is the only thing working right now, but not completely. Like I said before, the Fn+F5 should enable/disable the wlan AND the bluetooth, but with this acpi driver, the bluetooth is not enabled any more.
The bluetooth is an internal USB device, which gets connected and disconnected from the USB bus when pressing Fn+F5:

usb 3-1: new full speed USB device using address 4
Bluetooth: HCI USB driver ver 2.6
usbcore: registered new driver hci_usb

Quoted 44 lines

On a T41 it inserts in the kernel only if I replace _SB.GDCK with _SB.PCI0.PCI1.DOCK.
If I don't, I get the following message:
insmod ./ibm_acpi.ko
insmod: error inserting './ibm_acpi.ko': -1 No such device
and in dmesg I found:
ibm_acpi: acpi_get_handle(\_SB.GDCK) failed
At a fist glance, hot-keys work, but the Fn-F5 does not enable bluetooth anymore.
I will get back with more feedback.
Thanks,
Paul

Thanks a lot, Paul, that was very helpful. It looks like I have some work to do.

If it's not too much trouble, I'd appreciate it. In the mean time, I'm looking at a hacked one off http://acpi.sf.net, so it's not very important.

Interesting. It seems that the T41 has the fan presets but no methods to use them. No standard ACPI fan device either. Does it actually have a fan? :-) I don't think there's much I can do for now apart from disabling the fan control.

Quoted 4 lines

The hotkey is the only thing working right now, but not completely. Like I said before, the Fn+F5 should enable/disable the wlan AND the bluetooth, but with this acpi driver, the bluetooth is not enabled any more.

That was to be expected. The code for the hot keys usually does something like this:

if hot key events enabled
generate event
else
invoke default hot key behaviour

In this case, the default behaviour is toggling bluetooth on and off. This should be easy to fix, though - a /proc/acpi/ibm/bluetooth control would allow you to toggle the state from the ACPI handler for Fn-F5.

I'll make it look for that. As Shaohua noted, though, I'm not yet scanning the PCI bus on the dock.

I saw that you use idectl for enabling the cdrom on the docking station. I also use idectl to enable my cdrom or secondary hard-disk in the UltraBay slim, but I have the following problems: DMA is not working any more for hdc after "idectl 1 rescan" After some rescan cycles I will have a lot of ide1 in /proc/ide/
See http://bugme.osdl.org/show_bug.cgi?id=2261
Do you have the same problems ?

Yes, although I hadn't noticed DMA was off. I found all these posts saying that both IDE and ACPI hot plugging are basically not supported yet, so I was happy to get docking and undocking with the CD drive working at all...

Thanks,
Boris

But in this case I think it would be less flexible. Maybe somebody does not want to enable bluetooth by default with Fn-F5, but only the wlan. In windows you can specify what action to have for Fn-F5, like enable/disable for bluetooth, wlan, or bluetooth+wlan.
If you enable/disable the bluetooth from notify handler, then you could not just enable/disable the wlan with Fn-F5.

It's still easier to do that from the notify handler and provide an interface to enable / disable the specific bits at user request. By moving it completely to userspace you add another layer of redirection which most users won't need (as they don't give a damn about writing and configuring glue scripts) as opposed to having your driver do as expected for most non-developers. As I said, it's easy to come up with an interface to change the default behaviour if anybody should wish so.

As I said, it's easy to come up with an interface to change the default behaviour if anybody should wish so.

Come to think of it, that interface already exists. Here is what the DSDT does for Fn-F5 (I slightly oversimplified in my previous message):

if a particular bit is set in the mask
if hot key events are enabled
generate ACPI event
else
invoke default hot key behaviour

This means that if the driver leaves the mask alone on insmod, the function keys will continue with their default behavior (e.g. Fn-F5 will toggle bluetooth, Fn-F7 will switch the screens, etc.). Once the mask is set to include the relevant bits, the default behavior is stopped and instead ACPI events are generated.

Version 0.1 set the mask on insmod for convenience, but the plan is to not do that in 0.2. If you want hotkey events, after insmod you'll have to:

echo enable > /proc/acpi/ibm/hotkey
echo ffff > /proc/acpi/ibm/hotkey

How's that?

I guess it might still be a good way to go with both, i.e. do the AML magic to turn the device on _and_ generate an event in case the user wanted to run hciattach for example. On the other hand, if that's a USB device hotplug may suffice.

Hi Boris,

Right now, I am using the way you mentioned above, with the hotkey mask, but it does not provide enough flexibility.
That is because now I can have one or another, but I cannot have both. What should I do if I want to activate both bluetooth and wireless ? I have to enable bluetooth AND have an hotkey event for activating the wireless, because by default is taken care only of the USB bluetooth, but nothing is done for the wireless.

Thanks,
Paul

Make wireless interface up and activate Bluetooth by executing

To make wireless interface up, I need the hotkey
event.
Anyway, this will be solved in next release.

Hmm, SBDC, GBDC method under HKEY device may be related. SBDC takes two mask value.( 0x2 seems Wireless lan related and 0x4 is Bluetooth attach method, it seems).
I tried to activate wireless lan in my environment by calling the method.
But the wireless LED was not changed so I imageine that it is not useless for wireless LAN.

Wireless LED seems to be connected to MINI PCI GPIO register.

Atheros drivers will take care of that if compiled with a special option.

That's what I'm using to control bluetooth in 0.2. As far as I can tell, 0x2 turns bluetooth on and off, but I have no idea what 0x4 does. It doesn't seem to affect the wireless in any way, so I think it's also bluetooth-related. I've left it as "unknown" in /proc/acpi/ibm/bluetooth, hopefully somebody who has bluetooth support and devices can figure out what it does.

Consider doing that from the notify handler, I'd bet that's what the Windows driver does.

That'd be easier but a lot less flexible. Besides, I'd like to expose the bluetooth presence and status to user space anyway. Any particular reason not to give full control to user space? That'd be more in line with how the other keys work, too. All of them now just generate ACPI events and it's up to the acpid handler to make them do whatever is necessary. I find that very useful for taking pre- and post-event actions, or for remapping keys.

From my experience, users find it confusing if something works before the

module loads but stops afterwards (and that would be common since you can't force a sane configuration, especially that you'll probably find machines that do the BT stuff differently).

The hotkey is the only thing working right now, but not completely. Like I said before, the Fn+F5 should enable/disable the wlan AND the bluetooth, but with this acpi driver, the bluetooth is not enabled any more.
That was to be expected. The code for the hot keys usually does something like this:
if hot key events enabled
generate event
else
invoke default hot key behaviour

Yes, I know that. I managed to test a T50p in a dock, but it doesn't work as expected. So there may be some IBM magic added in here.

Do you have the same problems ?
Yes, although I hadn't noticed DMA was off. I found all these posts saying that both IDE and ACPI hot plugging are basically not supported yet, so I was happy to get docking and undocking with the CD drive working at all...

Well, they are not supported, but somewhat working half way. Anyway, if you put a secondary hard disk in the bay as I do, then you WILL want DMA for sure.

Boris,

First, I want to apologize if this is a little bit off-topic for this list, but I think that maybe this could be interesting for the others too.

I saw that you use idectl for enabling the cdrom on the docking
station. I also use idectl to enable my cdrom or secondary hard-disk in the UltraBay slim, but I have the following problems: DMA is not working any more for hdc after "idectl 1 rescan" After some rescan cycles I will have a lot of ide1 in /proc/ide/

See http://bugme.osdl.org/show_bug.cgi?id=2261

Hi Boris,
On a T41 it inserts in the kernel only if I replace _SB.GDCK with _SB.PCI0.PCI1.DOCK.
If I don't, I get the following message:
insmod ./ibm_acpi.ko
insmod: error inserting './ibm_acpi.ko': -1 No such device
and in dmesg I found:
ibm_acpi: acpi_get_handle(\_SB.GDCK) failed
At a fist glance, hot-keys work, but the Fn-F5 does not enable bluetooth anymore.
I will get back with more feedback.

Hi,
This is the first public release of my ACPI driver for IBM ThinkPad laptops. The features currently supported are:
- hot keys (Fn key combinations)
- docking and undocking
- some basic fan speed control
Note that I've only tested on a ThinkPad X40 with the X4 UltraBase. I suspect many other recent models are sufficiently similar to work with this driver but I have no such reports yet.

I'll release this on the linux-thinkpad list as well, but I thought I'd get some comments here first. This is my first foray into the ACPI code, so do let me know if I'm doing something horribly wrong. :-)

Hi Alan,

As far as I remember, I had the same problems with 2.4.26. But I will try 2.4.27 these days.

You can easily try on your computer to do:
idectl 1 off
idectl 1 on

now see if hdparm -D1 /dev/hdc works anymore (assuming you have something on /dev/hdc)

and also you will have two of ide1 in /proc/ide

Just give it a try if you have 2.4.x kernel.

Thanks,

Hi Boris,

I found this in the README file:

TODO

The following features are planned but not yet implemented:
- LCD on/off switching
- LCD / external display switching
- LED status and control

Other features I'd like to support but don't yet have any information on:
- TrackPoint tap enable/disable
- motion sensor support

And I can add more ideas to it:

Methods for adjusting LCD brightness and sound volume, and then we can use an external keyboard to control them. (something like /proc/acpi/ibm/brightness and /proc/acpi/ibm/volume )

Method to soft eject/insert the device in UltraBay, and capture the event generated by the pull-off device-from-bay button.

As for the tapping on Trackpoint, I think it can be programed with the synaptic driver which can do more than that.
See: http://w1.894.telia.com/~u89404340/touchpad/

And the motion sensor I don't think is an acpi device.

Thanks,
Paul

Hi Erik,

Even now, without proper ACPI support, you don't have to reboot your thinkpad to do that.
If you are using an ACPI enabled kernel, then you can just "idectl 1 off"
pull out your cdrom
insert your battery
use the battery
eject the battery
insert the cdrom
"idectl 1 on" or "idectl 1 rescan"
use the cdrom

however the DMA on the cdrom will not work because of this bug:
http://bugme.osdl.org/show_bug.cgi?id=2261

Also, you can use hotplug utility instead of idectl.

Good luck,
Paul

In reply to Borislav Deianov

Hi,

This is the second alpha release of my ACPI driver for IBM ThinkPad laptops. The features currently supported are:

- Fn key combinations
- Bluetooth enable and disable
- limited docking and undocking

So far, it has been tested on several T and X series ThinkPads. I appreciate any user reports, either successful or unsuccessful. Please see the included README for more information.

Changes since 0.1:

- fixed problems preventing insmod on the T series and the X20
- implemented bluetooth enable/disable
- hotkey events are disabled by default, need explicit enable
- fixed compilation problem on vanilla 2.6.7
- dropped fan control, was useless in its current state

(Sorry, no web page yet. One thing at a time.)

Thanks,
Boris

Hello Boris,

This is the second alpha release of my ACPI driver for IBM ThinkPad laptops. The features currently supported are:
Argh, forgot to actually attach the .tar.gz.

thanks a lot for programming the ibm-acpi support.

I guess my R31 is currently not yet supported, well since no path could be found ibm_acpi first could not be loaded. Without further knowledge of what I'm doing ;-) I added an entry for it:

char *ibm_hkey_paths[] = {
        "\\_SB.PCI0.ISA.EC.HKEY", /* X20 */
        "\\_SB.PCI0.LPC.EC.HKEY", /* X31, X40, T30, T40, T41 */
        "\\_SB.PCI0.ICH3.HKEY", /* R31 */
        NULL,
};

Could you please verify from the attached deassembled dstd if this is correct?

The next problem to load the module was docking support, though the R31 has a docking slot I'm not so sure if docking is supported at all.For a first test and to get the module loading I simply removed the hole docking stuff from "struct ibm_struct ibms".
This worked, but has to be improved of course.

No I can enable hotkey, but setting any mask fails:

beno:/proc/acpi/ibm# cat hotkey
state:          disabled
mask:           0000
commands:       enable, disable, reset, <mask>

beno:/proc/acpi/ibm# echo enable >hotkey
beno:/proc/acpi/ibm# cat hotkey
state:          enabled
mask:           0000
commands:       enable, disable, reset, <mask>

beno:/proc/acpi/ibm# echo "ffff" >hotkey
beno:/proc/acpi/ibm# cat hotkey
state:          enabled
mask:           0000
commands:       enable, disable, reset, <mask>

The most wanted feature from my side is certainly fan control. After I sent my R31 to repair last summer since it got much to hot, IBM rejusted the fan control which made the fan running permanently, though they only needed to make the cooler fitting properly on the cpu.

In v0.1 there was some basic fan control stuff, unfortunality I currently have no access to those sources to compare what happend with it. Is there any chance to get this working? As I really hate noisy fans, I'm willing to investigate time to get some basic fan control, I just need a pointer into the right direction.

Thanks,
Bernd

Hi,
This is the second alpha release of my ACPI driver for IBM ThinkPad laptops. The features currently supported are:
- Fn key combinations
- Bluetooth enable and disable

Without your driver, Bluetooth enable/disable already works fine on my T42p.

When I press Fn+F5, the led lights up and the following messages show up in dmesg:

usb 4-1: new full speed USB device using address 2
Bluetooth: Core ver 2.6
NET: Registered protocol family 31
Bluetooth: HCI device and connection manager initialized
Bluetooth: HCI socket layer initialized
Bluetooth: HCI USB driver ver 2.6
usbcore: registered new driver hci_usb

When I press Fn+F5 again, the led turns off and I get:

usb 4-1: USB disconnect, address 2

Does it work differently on older ThinkPads? Can I use your driver without messing up the already working Bluetooth enable/disable?

Yes, you can. When you first load the driver, Fn-F5 will continue to work the same way. If you then enable hotkey events and set the mask to include Fn-F5 (see the README for the full details), Fn-F5 will instead generate an ACPI event. Using acpid, you can set a script to run on this event. You can do whatever you want in the script, including controlling Bluetooth via /proc/acpi/ibm/bluetooth.

Boris

Does it work differently on older ThinkPads?

Yes. My A31p, at least, will only enable the Bluetooth adapter when I hit a dedicated hardware button on the screen.

This module, presumably, will allow me to control it from software, just like Windows does.

hotkey/video framework [was: ibm-acpi-0.2]

In reply to a message not in the archive

Hi,

'Fn key combination' is common on machines,
so I think we need some abstraction layer or framework on acpi core.

I wrote acpi driver for Panasonic Let's note laptops recentry. It supports lcd brightness control and hotkey. Toshiba and asus driver also support hotkey combination.

How do you think about hotkey framework?
Does anyone already work for it?

eg)

proc interface:

/proc/acpi/hotkey/keymap   --- key num - event meaning map
/proc/acpi/hotkey/mask     --- hotkey enable/disable mask.
/proc/acpi/event           --- send hotkey event to acpid

/proc/acpi/video/lcd/brightness --- control lcd brightness
/proc/acpi/video/outdev --- control video output (lcd/crt)
/proc/acpi/ibm/* --- vendor specific devices conrol

Source tree:
drivers/acpi/video.c -- video/lcd abstraction driver.
drivers/acpi/hotkey.c -- hotkey abstraction driver.
drivers/acpi/oem/asus_acpi.c
drivers/acpi/oem/toshiba-acpi.c
drivers/acpi/oem/pcc-acpi.c
drivers/acpi/oem/ibm-acpi.c -- vendor specific drivers.
which implement hotkey, video, and lcd etc.

Hi,
'Fn key combination' is common on machines,
so I think we need some abstraction layer or framework on acpi core.

One possibility is to just agree on the proc file format and ACPI events for the common features, then have each driver implement them separately. This would probably be simpler than trying to come up with some sort of a wrapper framework as the code involved is fairly simple and there probably isn't much we can share. Then again, there might be, I haven't looked.

I'd be up for something like this, although I'll be busy for a while getting all the ThinkPad features to work.

ibm-acpi-0.3

In reply to Borislav Deianov

Hi,

This is the third alpha release of my ACPI driver for IBM ThinkPad laptops. The features currently supported are:

- Fn key combinations
- Bluetooth enable and disable
- turning the LCD off, brightness control
- ThinkLight on/off
- limited docking and undocking

So far, it has been tested on several T, X and R series ThinkPads. I appreciate any user reports, either successful or unsuccessful. Please see the included README for more information.

Changes since 0.2:

- fixed problems preventing insmod on the R40
- implemented LCD brightness control and turning off
- implemented ThinkLight on/off

I just noticed that turning the LCD off only works in X, not on the console, at least for me. I'll need to look into this further.

Finally, a download URL:

http://bkernel.sf.net/tmp/ibm-acpi-0.3.tar.gz

Still no web page.

I'll be on vacation for the next three weeks, so I'll be a little slow with replies to email. If you are replying to the lists, I'd appreciate a CC, I'd see it sooner that way.

Re: ibm-acpi-0.3

Hi Boris,

Here is the feedback for the new features of ibm_acpi-0.3 on IBM T41/R50p :

ThinkLight works (on/off)
LCD (up/down/off) does not work, but it does increment the brightness level reported by "tpb".
This means that if I "echo up > lcd", the tbp OSD increments, but the LCD is at the same level of brightness.
Moreover "echo off > lcd" triggers an AccessIBM button event in "tpb"

And have a happy holiday.

Thanks,
Paul

The radio hot key sends an ACPI event,
and the acpid example calls this radio.sh:

Does this means that the button press magically changed the state of the radio in hardware? I didn't see any processing inside the driver to do that.

No. The listed radio.sh script just unloads the ipw2100 module from memory which effectively disables the wireless network connection.

So rather than actually disabling the radio, we're diabling the network by unloading the driver? Is there an indicator light that says if the radio is enalbed? Does is stay on?

IBM hotkey has a unique ID. In T40, it's 'IBM0068'. I guess other IBM laptops also use it. Using a hardcode path in the patch possibly isn't a good idea.

Agreed. I was originally using acpi_bus_register_driver() and refering to devices by HID but that turned out to not work very well for the dock (ACPI drops it if it's not present at boot) and embedded controller (the ec driver has already grabbed it). So I switched to looking things up by the path. I see your point, though, I'll see what I can do.
please stick with the HID method if you can.

I'd like to, but, for the most part, I can't. The two problems above still stand: I need to access devices not present at boot time, and I need to access devices already grabbed by other drivers. In addition, I need to access devices and methods which just don't have HIDs. Basically, out of the six features currently supported by ibm-acpi, two can be done via acpi_bus_register_driver(). For the other four, I need to call acpi_get_handle() (with several hard-coded alternative paths). I use the latter method for all features, simplifies the structure of the driver quite a bit.

Would you consider something like acpi_get_handle_by_hid() (which can also access non-present devices)? That would help a lot.

The "antenna" LED goes off and power consumption goes down a bit, so I assume unloading the module does turn off the radio. My laptop doesn't have a software kill switch, so not much else I can do.

The laptop might not actually have any RF switch circuitry to signal the GPIO pin -- so on detection of keypress, it fully removes and reloads the module (which will have the result of powering off/on the radio with the side effect of loading/unloading any modules and services also listed in the network service)

As of 0.53 (since the proc entries are all broken in 0.52) the script could be changed to do something more along these lines (until we change from proc to sysfs and from strings to ints):

#!/bin/sh
if grep -q disabled /proc/net/ipw2100/eth1/state; then
echo 0 > /proc/net/ipw2100/eth1/state
else
echo 1 > /proc/net/ipw2100/eth1/state
fi

The above will check the state of the RF kill switch. If the radio is disabled, it enables it (by turning off the kill state), etc. The link state will toggle based on whether the device is associated -- and that is likely what the various service scripts should be tied to (vs. whether or not the module is loaded)

Surely going to /sys/bus/pci/devices/whatever/power/state is more useful? In the long run that'll probably also power down the device, which seems to save me a few hundred mW over just removing the module.

Hi,
This is the first public release of my ACPI driver for IBM ThinkPad laptops. The features currently supported are:
- hot keys (Fn key combinations)
- docking and undocking
- some basic fan speed control
Note that I've only tested on a ThinkPad X40 with the X4 UltraBase. I suspect many other recent models are sufficiently similar to work with this driver but I have no such reports yet.

I'll release this on the linux-thinkpad list as well, but I thought I'd get some comments here first. This is my first foray into the ACPI code, so do let me know if I'm doing something horribly wrong. :-)
(Sorry, no web page yet. One thing at a time.)
