commit b5488a63ba68277127797f24c809a846d34ab065 Author: Aladyshev Konstantin aladyshev@nicevt.ru Date: Tue Dec 18 23:15:55 2012 +0400
Supermicro H8QGI: Fix routing from 16 to 55 in ACPI table
H8QGI board has 2 IO-APICS with 56 IRQ’s:
IOAPIC[0]: GSI 0-23 - SB700 southbridge IOAPIC[1]: GSI 24-55 - RD890 northbridge
`gDefaultApicDeviceInfoTable[]` structure in northbridge code
vendorcode/amd/cimx/rd890/nbIoApic.c
has IO-APIC interrupt mapping for HT and IOMMU set to last 31 IRQ pin (24+31=55).
CONST APIC_DEVICE_INFO gDefaultApicDeviceInfoTable[] = { // Group Swizzling Port Int Pin {0, 0, 31}, //HT {0, 0, 31}, //IOMMU […]
Also the same value (55) can be found in original Supermicro BIOS ACPI DSDT.
