SBST support

SBST support

[Pavel Machek]

Hi!

I was asked to do SBST support for Linux. What is strange that all
info except "design capacity critical" can be read from _BIF, linux
does that and it seems to work.

Is SBST some kind of legacy table? Should it be supported? What if it
returns different value from _BIF?

Excerpt from APCI 2.0 Spec:
-----------------------------

"If the platform supports batteries as defined by the Smart Battery 
Specification 1.0 or 1.1, then an Smart Battery Table (SBST) is 
present. [...] OSPM uses these tables with the capabilities of the 
batteries to determine the different trip points."

As far as i understand this, it is no legacy table, but one many 
tables inside the ACPI subsystem.

Hope this helped,

Stefan
