Summary:	F5 and F6 keys on Macbook Air (and possibly other macbooks)

Attachments:	add (and correct) FN+F5 and FN+F6 keys for macbook air

Description Henrik Rydberg 2008-06-21 07:30:19 UTC

Latest working kernel version: unknown
Earliest failing kernel version: unknown
Distribution: ubuntu hardy
Hardware Environment: macbook air
Software Environment: kernel source from git tree
Problem Description: hid-input.c contains no mapping for F5 and F6 keys

Steps to reproduce: none

Being a complete newcomer to kernel work, this might have other solutions (based on quirks?), but here it is anyway:

In drivers/hid/hid-input.c, the apple_fn_keys translation table contains no entries for the F5 and F6 keys, and the FN+F3 key is mysteriously mapped to FN_F5. A patch is attached which maps the F5 and F6 keys to KBDILLUMDOWN and UP, respektively, which make them work as keyboard backlight control keys. Again, please note that this is only checked on the macbook air, and if there are other means of solving this, please disregard the patch.
