+Abstract:
+
+ IGD OpRegion/Software SCI Reference Code for the Baytrail Family.
+ This file contains the interrupt handler code for the Integrated
+ Graphics Device (IGD) OpRegion/Software SCI mechanism.

+
+
+//NOTES:
+//
+// (1) The code contained in this file inherits the scope in which it
+// was included. So BIOS developers must be sure to include this
+// file in the scope associated with the graphics device
+// (ex. \_SB.PCI0.GFX0).
+// (2) Create a _L06 method under the GPE scope to handle the event
+// generated by the graphics driver. The _L06 method must call
+// the GSCI method in this file.
+// (3) The MCHP operation region assumes that _ADR and _BBN names
+// corresponding to bus 0, device0, function 0 have been declared
+// under the PCI0 scope.
+// (4) Before the first execution of the GSCI method, the base address
+// of the GMCH SCI OpRegion must be programmed where the driver can
+// access it. A 32bit scratch register at 0xFC in the IGD PCI
+// configuration space (B0/D2/F0/R0FCh) is used for this purpose.
+
+// Define an OperationRegion to cover the GMCH PCI configuration space as
+// described in the IGD OpRegion specificiation.
