Re: [coreboot] ACPI Errors on Lenovo X201i

[Matthias Gazzari]

Hi Patrick,

I built with the current origin/master, so the Nehalem fix
https://review.coreboot.org/#/c/coreboot/+/26287/ is already included. I
see "ACPI:    * H8" and have the following mentions of HBDC inside the
dsdt.dsl:

External (HBDC, IntObj)

and

Method (GBDC, 0, NotSerialized)
{
    If (HBDC)
    {
    	Local0 = One
    	If (BTEB)
    	{
    		Local0 |= 0x02
    	}

Local0 |= 0x04
    	Return (Local0)
    }
    Else
    {
    	Return (Zero)
    }
}

Method (SBDC, 1, NotSerialized)
{
    If (HBDC)
    {
    	Local0 = ((Arg0 & 0x02) >> One)
    	BTEB = Local0
    }
}

Hope that helps.

Cheers,
Matthias
