sci - The total number of times the ACPI SCI
has claimed an interrupt.
Expand All @@ -89,13 +89,6 @@ Description:

error - an interrupt that can't be accounted for above.

invalid: it's either a wakeup GPE or a GPE/Fixed Event that
doesn't have an event handler.

disable: the GPE/Fixed Event is valid but disabled.

enable: the GPE/Fixed Event is valid and enabled.

Root has permission to clear any of these counters. Eg.
# echo 0 > gpe11

Expand All @@ -104,43 +97,3 @@ Description:

None of these counters has an effect on the function
of the system, they are simply statistics.

Besides this, user can also write specific strings to these files
to enable/disable/clear ACPI interrupts in user space, which can be
used to debug some ACPI interrupt storm issues.

Note that only writting to VALID GPE/Fixed Event is allowed,
i.e. user can only change the status of runtime GPE and
Fixed Event with event handler installed.

Let's take power button fixed event for example, please kill acpid
and other user space applications so that the machine won't shutdown
when pressing the power button.
