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

 Hi Matthias,
 It looks like the Ssdt generator on x201/nehalem doesn't work as expected.
 It was broken and has been fixed in commit https://review.coreboot.org/#/c/coreboot/+/26287/
 Do you see "ACPI:    * H8" in coreboot console log ?
 Do you see any HBDC method in disassembled ACPI ?
 Regards Patrick
