Subject: Re: acer-wmi is unnecessarily loaded on a Lenovo Ideapad S12

Message-ID: <20110304235927.GA31464@srcf.ucam.org> (raw)

Looking at this, it seems that the affected machines have AMW0_GUID1 but
none of the WMID GUIDs. By the looks of things this is just a
semi-standardised way to trigger an SMM trap and communicate with the
firmware. This makes things tricker to track down (because once we're in
SMM we have no way of knowing what the firwmare's doing), but
potentially there's some method to identify the machine here. Carlos, do
we have any idea what the inputs and outputs for this method mean other
than what's in AMW0_set_capabilities()?
