Thus this option is a debug option that helps to write ACPI drivers
and can be used to identify ACPI code or EC firmware bugs.
-config ACPI_PROC_EVENT
- bool "Deprecated /proc/acpi/event support"
- depends on PROC_FS
- default y
- help
- A user-space daemon, acpid, typically reads /proc/acpi/event
- and handles all ACPI-generated events.
-
- These events are now delivered to user-space either
- via the input layer or as netlink events.
-
- This build option enables the old code for legacy
- user-space implementation. After some time, this will
- be moved under CONFIG_ACPI_PROCFS, and then deleted.
-
- Say Y here to retain the old behaviour. Say N if your
- user-space is newer than kernel 2.6.23 (September 2007).
