RE: [PATCH] [RESEND] Add Dell laptop backlight brightness display

[Michael_E_Brown]

Yes, the list of things to do is called the token table. I am working on
getting permission to release it. As it is, I am releasing tokens as
people ask for them, on a case by case basis.

I, personally, do not build or design our laptops, nor do I have any
sway with those that do. Crying about it isn't going to help, sorry.

If you would care to move the discussion to libsmbios-devel, I would be
more than happy to help you get the token you need and write a
util/lib/whatever to do what you need.

Oh, heavens. Could you people (and here I include pretty much everyone
who manufactures laptops) please (please!) just implement the ACPI video
extension? We're going to end up having to ship a 200K library for each
and every laptop manufacturer who's decided to implement basic
functionality in a proprietary manner, and it's going to make me cry.

(Which SMI do I need for brightness control? The libsmbios docs seem to
be remarkably quiet on what functionality is actually available, and I'm
not keen on calling things randomly :))
