DSDT errors

DSDT errors

[Mark Eaton]

I am looking at my DSDT for an acer ferrari 300 laptop. It hangs on resume and 
I believe the problem (at least partially) is the _WAK function which doesn't 
return a value. The question is what should it return ?

The method is as below.

    Method (\_WAK, 1, NotSerialized)
    {
        Store (0x01, \_SB.PCI0.ISA.LIDP)
        If (LEqual (Arg0, 0x03))
        {
            \_SB.Z001 (0x91)
            Acquire (\_SB.PSMX, 0xFFFF)
            Store (0x80, \_SB.BCMD)
            Store (0x07, \_SB.DID)
            Store (Zero, \_SB.SMIC)
            Release (\_SB.PSMX)
        }

        If (LEqual (Arg0, 0x04))
        {
            Acquire (\_SB.PSMX, 0xFFFF)
            Store (0x80, \_SB.BCMD)
            Store (0x04, \_SB.DID)
            Store (Zero, \_SB.SMIC)
            Release (\_SB.PSMX)
            Store (\_SB.INF, Local0)
            If (LEqual (Local0, 0x07)) {}
            Else
            {
                Store (Local0, Local1)
                Store (Local0, Local2)
                Store (Local0, \_SB.PCI0.AGP.VGA.DABL)
                And (Local1, 0x01, \_SB.PCI0.AGP.VGA.CRTA)
                And (Local2, 0x02, \_SB.PCI0.AGP.VGA.LCDA)
            }
        }

        Store (0xBA, \_SB.PCI0.ISA.Z002)
        \_SB.Z001 (0x97)
    }


thanks.
If this has nothing to do with my problem I can supply the entire dsdt for 
someone to have a look at.

RE: DSDT errors

[Moore, Robert]

7.3.7   \_WAK (System Wake)
After the system wakes from a sleeping state, it will invoke the \_WAK method and pass the sleeping state value that has ended. This operation occurs asynchronously with other driver notifications in the system and is not the first action to be taken when the system wakes. The AML code for this control method issues device, thermal, and other notifications to ensure that OSPM checks the state of devices, thermal zones, and so on, that could not be maintained during the system sleeping state. For example, if the system cannot determine whether a device was inserted or removed from a bus while in the S2 state, the _WAK method would issue a devicecheck type of notification for that bus when issued with the sleeping state value of 2 (for more information about types of notifications, see section ‎5.6.3, “Device Object Notifications”). Notice that a device check notification from the \_SB node will cause OSPM to re-enumerate the entire tree .
Hardware is not obligated to track the state needed to supply the resulting status; however, this method must return status concerning the last sleep operation initiated by OSPM. The result codes can be used to provide additional information to OSPM or user. 
Arguments:
0	The value of the sleeping state (1 for S1, 2 for S2, and so on).
Result Code (2 DWORD package):
Status	Bit field of defined conditions that occurred during sleep.
	0x00000000	Wake was signaled and was successful
	0x00000001	Wake was signaled but failed due to lack of power.
	0x00000002	Wake was signaled but failed due to thermal condition.

	Other	Reserved
PSS	If non-zero, the effective S-state the power supply really entered. 

This value is used to detect when the targeted S-state was not entered because of too much current being drawn from the power supply. For example, this might occur when some active device’s current consumption pushes the system’s power requirements over the low power supply mark, thus preventing the lower power mode from being entered as desired.

RE: DSDT errors

[Moore, Robert]

But actually, we don't look at the return value anyway (yet)

    Status = AcpiEvaluateObject (NULL, METHOD_NAME__WAK, &ArgList, NULL);
    if (ACPI_FAILURE (Status) && Status != AE_NOT_FOUND)
    {
        ACPI_REPORT_ERROR (("Method _WAK failed, %s\n", AcpiFormatException (Status)));
    }
    /* TBD: _WAK "sometimes" returns stuff - do we want to look at it? */

Ok so the problem probably isn't the dsdt.
Thanks.
