[ltp] thinkpad-acpi (T6x/R6x/X6x): requesting testers for wireless switch behaviour

[Henrique de Moraes Holschuh]

In order to add rfkill support to thinkpad-acpi, and have it work really
well, I need to know how the BLUETOOTH and WWAN switches (those
reported/modified by /proc/acpi/ibm/wan and /proc/acpi/ibm/bluetooth)
behave IN RELATION TO the *hardware* slider radio switch (not the fn+f5
hotkey).

I believe this hardware slider switch is only present on R6x/T6x/X6x,
but if your X300, Z6x or R5x has one, I'd like to hear from you as well.

Basically, I need to know some data points and I'd appreciate if some
T6x/R6x/X6x owners could run the tests below and report back.  I'd
appreciate even more if I could get a report for every thinkpad model to
make sure the behaviour stays the same (i.e. one for the T60, one for
the T61, one for the X60, one for the X61...).


1. ThinkPad Model and BIOS version (dmidecode can tell you this)

2. Turn all radios ON (including bluetooth and wwan if you have it), and
make sure you do it with the radio switch in the "on" position.  Now,
move the switch to the radios-off position.

2a. What state does /proc/acpi/ibm/wan and /proc/acpi/ibm/bluetooth
report?

2b. If they report that WWAN and BT are off, are they *really* off?

2b1. Can you force WWAN and BT to the ON state even while the radio
switch is in the off position?

2c. If they report that WWAN and BT are on, are they *really* on?

3. Turn all radios *off* through /proc/acpi/ibm/wan and
/proc/acpi/ibm/bluetooth and also by sliding the radio switch to the off
position.

3a. are all radios really off?

3b. Now, slide the radio switch to the "on" position

3c. What state does /proc/acpi/ibm/wan and /proc/acpi/ibm/bluetooth
report?

3d. is that state true (i.e. if it says off, are the radios really off?
if it says on, are the radios really on)?


I believe turning WWAN and bluetooth off through the thinkpad firmware
actually unplugs them from the USB bus.  If that's true, it should be a
really simple matter to know if it is working or not, as they will show
up and disappear from lsusb output (run lsusb as root)...
