This register specifies the interrupt message address. For platforms supporting only
interrupt messages in the 32-bit address range, this register is treated as read-only
(0).

Description
Core
Message upper address (MUA): This register need to be
implemented only if hardware supports 64-bit message
address. If implemented, the contents of this register
specify the upper 32-bits of a 64- bit MSI write transaction.
If hardware does not support 64-bit messages, the register
is treated as read only (0).
12.3.13 AFLOG_REG—Advanced Fault Log Register

64 bits
This register specifies the base address of memory-resident fault-log region. This
register is treated as read only (0) for implementations not supporting advanced
translation fault logging (AFL field reported as 0 in the Capability register). This register
is sticky and can be cleared only through powergood reset or via software clearing the
RW1C fields by writing a 1.

Core
Fault Log Address (FLA): This field specifies the base of
size-aligned fault-log region in system memory. Hardware
may ignore bits 63: N, where N is the host address
width.
Software specifies the base address and size of the fault
log region through this register, and programs it in
hardware through the SFL field in the Global Command
register.
When implemented, reads of this field returns value that
was last programmed to it.
Fault Log Size (FLS): This field specifies the size of the
fault log region pointed by the FLA field.
The size of the fault log region is 2X * 4KB, where X is the
value programmed in this register.
When implemented, reads of this field returns value that
was last programmed to it.
