Should we? Why? We lose information doing that. Instead of a nice linear
0-100% brightness scale, you are now back to an 8 or 16-level non-linear
brightness scale.

That will work well with any firmware, and it will not remove functionality
from any box, while at the same time plugging the current issues

Heck, back to the video.c driver, you shouldn't even assume _BCL gives you a
sorted list after the second element. I admit it takes an special kind of
weird firmware to screw with _BCL like that, but the ACPI spec

Indeed. The ACPI spec provides a range of 0-100, without specifying what
this actually means (it gives

So be it, then. But my request that we get a way to add the information we

The thing is does this 0-100 value have a use to userspace? Its

Rounding to the nearest supplied _BCL value before we call _BCM apparently

As I said, give thinkpad-acpi the brightness_enable=1 parameter, and it will
export its backlight interface,

For thinkpad-acpi at least, it is not a regression. 2.6.23/0.16 did NOT
