Interrupt/SMM Region
This 4 MB range is used for processor specific applications. This region lies between
FEC0 0000h and FEFF FFFFh and is split into four 1 MB segments.
Interrupt/SMM Region
This region is used to support various processor and system functions. These functions
include I/O APIC control range which is used to communicate with I/O APIC controllers
located on Intel
enabled under register control. Transactions directed to this range are redirected to
physical memory located in the compatible (legacy) SMM space; 0A 0000h - 0B FFFFh.
The interrupt range is used to deliver interrupts. Memory read or write transactions
from the processor are illegal.
I/O APIC Controller Range
This address range FEC0 0000h to FEC8 FFFFh is used to communicate with the IOAPIC
controllers in the Intel
The APIC ranges are hard coded. Reads and writes to each IOAPIC region should be
sent to the appropriate ESI or PCI Express* port as indicated below.
