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.
