Attached patch adds a kernel thread to do polling on Toshiba hardware. Toshiba hardware is a little oddball, and does not provide ACPI events on some key presses, typically Fn hotkey buttons. The key interface is now polled, and events now matched to a list of toshiba specific scancodes, and are squirted to userspace using the INPUT subsystem. This means that toshiba laptops buttons "just work" without any userspace daemon (using uinput) such as fnfx or bodges such as using a userspace hal addon. Doing the polling in kernel is more efficient, and makes stuff just work out of the box. You can assign the keys using standard X keymaps, or using tools such as gnome-keybinding-properties. This is similar to other patches sent for the thinkpad_acpi driver, and is part of the "Unf*ck my keyboard" initiative to make multimedia keys just work. Changes from the first patch involve switching to a workqueue for the polling, not breaking the spaces in "hotkeys_via_input" and also masking out the fn key button up. toshiba_acpi.c | 228 +++++++++++++++++++++++++++++++++++++++++++++++++++------ 1 file changed, 206 insertions(+), 22 deletions(-) Signed-off-by: Richard Hughes
