Subject: [RFC PATCH 0/2] acpi: video: Allow forcing native backlight on non win8 laptops
Date: Tue,  3 Mar 2015 08:39:08 +0100	[thread overview]
Message-ID: <1425368350-4028-1-git-send-email-hdegoede@redhat.com> (raw)

Hi All,

I've long wanted to have a way for users to force native-backlight behavior as
that makes debugging backlight problems a bit easier.

And now a laptop has shown up which needs native backlight behavior for things
to work, has a non win8 ready bios, and I cannot use a quirk in the vendor
backlight driver as it implements both the acer-wmi and ideapad-laptop vendor
interfaces and putting the same quirk in 2 places is just wrong.

So I've finally written a small patch to allow forcing native-backlight
behavior as well as a second patch using this to add a quirk for said laptop.

For now this is just a RFC series as I'm waiting for confirmation from the
user that this actually fixes things, but I wanted to get the discussion going
beforehand in case anyone has any objections against the solution I've come
up with.

Regards,

Hans
