Interpretation of ACPI spec?

Hi all --

I've just sent the message below to the email address ([email protected]) given on the ACPI homepage for questions, comments, etc. And I've just received back a Host Unknown error.

Does anyone know whom I should contact for an interpretation on the specification?

cheers,

Rich

Dear Sirs,

I am currently implementing a Linux driver for the Smart Battery sections of the ACPI specification. I am writing to request clarification of the specification regarding Alarm Notify events issued by Smart Batteries.

The Smart Battery Data specification indicates that such events, typically triggered by low charge capacity or hardware failures, will be sent over the SMBus to the host at address 0x08. However, the ACPI specification is unclear what then happens to these events.

Indeed, the specification discusses what happens to Alarm Notify events from a Smart Battery Charger (section 10.1.1.2) or a Smart Battery System Manager/Selector (sections 10.1.1.3 & 10.1.1.4). However, the discussion of Smart Battery objects (section 10.1.2) makes no mention of the handling of Alarm Notify objects.

Please could you clarify

a) how I should detect Alarm Notify events dispatched by Smart Batteries

and

b) how I should determine which particular batteries issued the events

Many thanks for your assistance,
