    ACPICA: Parser: Fix for SuperName method invocation
    
    ACPICA commit 4b86d1046d06e462dae83ebcd5a66cc132a08f8f
    
    SuperName parameters that are in fact control method invocations were
    not handled correctly by the parser. This change fixes the problem
    by identifying these properly as method invocations. This affects
    about 14 different ASL operators that contain SuperName parameters.
    ACPICA BZ 1002.

It looks like there are some dynamically loaded SSDTs, I would like to see these.

#1325939

From"Moore, Robert" <robert.moore@intel.com>
Date2016-02-03 21:50 +0100
Message-ID<qYcxc-6PH-27@gated-at.bofh.it>
In reply to#1325212
After a bit of investigation, this looks to me like a latent bug in the ASL code, namely this SSDT:

DefinitionBlock ("ssdt10.aml", "SSDT", 1, "PmRef", "CpuPm", 0x00003000)

Here is the offending code:

    Scope (\_PR.CPU0)
    {
        Name (HC0, 0x00)
        Method (_PDC, 1, NotSerialized)  // _PDC: Processor Driver Capabilities
        {
            Store (CPPC, \_PR.CPU0._PPC) /* External reference */
        }


    Scope (\_PR.CPU0)
    {
        Method (_PPC, 0, NotSerialized)  // _PPC: Performance Present Capabilities
        {
            Store (CPLT, Local0)
            If (LLessEqual (Local0, 0x03))
            {
                Return (0x00)
            }

            Store (Subtract (Local0, 0x03), Local0)
            Return (Local0)
        }

This change:
>     ACPICA: Parser: Fix for SuperName method invocation

            Store (CPPC, \_PR.CPU0._PPC) /* External reference */


Causes \_PR.CPU0._PPC to actually be invoked -- As per the ACPI specification.

However, Windows doesn't actually invoke the method. In fact, as far as we can tell, it simply ignores the entire statement. So, the bug was never caught until we made the change.

So, we are going to have to revert the change, regardless of the ACPI specification.

Bob
