acpi_ec_gpe_query in ec.c is a function which should query the
execution of _Qxx events of
EC. You could try to insert some printk()s around...

Hello,
some new Vaio models are notifing hotkeys to the SNC device through the
EC (dsdt snippet[1]):
Device (EC)
{
Name (_HID, EisaId ("PNP0C09"))
...
Name (HF5P, 0x85)
Name (HF5R, 0x05)
...
Method (_Q50, 0, NotSerialized)
{
P8XH (Zero, 0x50)
SECR (HF5P)
Notify (SNC, 0x92)
}
Method (_Q51, 0, NotSerialized)
{
P8XH (Zero, 0x51)
SECR (HF5R)
Notify (SNC, 0x92)
}
...
}
and a kernel log[2] while pressing FnF5 with
/proc/acpi/debug_layer=0xFFFF0004
/proc/acpi/debug_level=0xffffffff
is appended below. I would expect to find some traces of the _Q50/_Q51
evaluation and sequent notification. And yes, sony-laptop (which handles
the SNC) registers a notify_handler (line 771 in current code) this way:
acpi_install_notify_handler(sony_nc_acpi_handle,
ACPI_DEVICE_NOTIFY,
sony_acpi_notify, NULL);
any clues why I don't get anything from that?
BTW: I'm Cc-ing one such vaio owner so that he can help answering some
questions if necessary.
