@Eric Burgess:
Hi Eric,
Your machine probably has one of the _DSM ACPI calls. Doing a grep on one of
the existing Dell DSDT gives me:
3863: Method (_DSM, 4, NotSerialized)
3903: Return
(\_SB.PCI0.IXVE.IGPU.PLAT (Arg3))
3909: Return
(\_SB.PCI0.IXVE.IGPU.DSMS (Arg3))
3971: Device (CRT0)
3980: Device (LCD0)
3989: Device (SVD0)
3998: Device (DPV0)
4092: Scope (\_SB.PCI0)
4188: Scope (\_SB.PCI0.IXVE.IGPU)
4190: OperationRegion (IGPU, PCI_Config, 0x40, 0x04)
4196: Name (DSMF, 0x00)
4197: Method (_DSM, 4, NotSerialized)
4199: Store ("------- DSM --------", Debug)
4217: Store (One, DSMF)
4243: CreateByteField (Arg3, 0x00, DSM2)
4244: If (And (DSM2, 0x10))
4246: And (DSM2, 0x0F, Local0)
4248: Notify (\_SB.PCI0.IXVE.IGPU,
0xD9)
4271: \_SB.PCI0.XVR0.Z01I.DGON ()
4277:
\_SB.PCI0.XVR0.Z01I.DGOF ()
4281:
\_SB.PCI0.XVR0.Z01I.HSTA ()
4295: Return (DSMS (Arg3))
So you should be able to take one of the existing acpi modules and
modify the acpi_get_handle call to use your specific ACPI method:
\_SB.PCI0.IXVE.IGPU.DSMS or something like that.
