However, hotkeys are not documented in the ACPI specification, so the drivers used undocumented vendor-specific hooks and turned out to be more different than the same. Further, the keys and the features supplied by each platform are different, so there will always be a need for platform-specific drivers. So the new plan is to delete hotkey.c and instead, work on the platform specific drivers to try to make them look the same to the user when they supply the same features. hotkey.c has always depended on CONFIG_EXPERIMENTAL Who: Len Brown <len.brown@intel.com> --------------------------- What: /sys/firmware/acpi/namespace When: 2.6.21 Why: The ACPI namespace is effectively the symbol list for the BIOS. The device names are completely arbitrary and have no place being exposed to user-space. For those interested in the BIOS ACPI namespace, the BIOS can be extracted and disassembled with acpidump and iasl as documented in the pmtools package here: http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/utils Who: Len Brown <len.brown@intel.com> --------------------------- What: /proc/acpi/button When: August 2007 Why: /proc/acpi/button has been replaced by events to the input layer since 2.6.20.
