Depending on the value of the use_alt_lcd_levels module parameter, one
of two functions is used for setting LCD brightness level. These

Haswell-based Fujitsu laptops (Lifebook E734/E744/E754) have a touchpad
toggle hotkey (Fn+F4) which is handled transparently to the operating
system: while an ACPI notification is sent to FUJ02B1 when Fn+F4 is
pressed, touchpad state is properly toggled without any explicit support
for this operation in fujitsu-laptop.
Skylake-based models (Lifebook E736/E746/E756) also have that hotkey,
but the touchpad is not toggled transparently to the operating system.
When Fn+F4 is pressed, an ACPI notification is sent to FUJ02E3. A
subsequent call to S000 (FUNC_RFKILL) can be used to determine whether
the touchpad toggle hotkey was pressed so that an input event can be
sent to userspace.
Relevant ACPI code:
Method (_L21, 0, NotSerialized)
{
...
If (AHKF)
{
Notify (\_SB.FEXT, 0x80)
}
...
}
Method (S000, 3, Serialized)
{
Name (_T_0, Zero)
Local0 = Zero
While (One)
{
_T_0 = Arg0
If (_T_0 == Zero)
{
Local0 |= 0x04000000
Local0 |= 0x02000000
Local0 |= 0x00020000
Local0 |= 0x0200
Local0 |= 0x0100
Local0 |= 0x20
}
ElseIf (_T_0 == One)
{
...
If (AHKF & 0x08)
{
Local0 |= 0x04000000
AHKF ^= 0x08
}
...
} ...
Break
}
Return (Local0)
}
Pressing Fn+F4 raises GPE 0x21 and sets bit 3 in AHKF. This in turn
results in bit 26 being set in the value returned by FUNC_RFKILL called
with 1 as its first argument. On Skylake-based models, bit 26 is also
set in the value returned by FUNC_RFKILL called with 0 as its first
argument (this value is saved in fujitsu_hotkey->rfkill_supported upon
module initialization), which suggests that this bit is set on models
which do not handle touchpad toggling transparently to the operating
system.
Note that bit 3 is cleared in AHKF once FUNC_RFKILL is called with 1 as
its first argument, which requires fujitsu-laptop to handle this hotkey
in a different manner than the other, GIRB-based hotkeys: two input
events (press and release) are immediately sent once Fn+F4 is pressed.
