Processor Configuration Registers 

This register specifies the base address of the memory-resident fault-log region. This 
register is treated as RsvdZ for implementations not supporting advanced translation 
fault logging (AFL field reported as 0 in the Capability register).

Fault Log Address (FLA) 
This field specifies the base of 4 KB aligned fault-log region in 

system memory. Hardware ignores and does not implement bits 

63:HAW, where HAW 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 return the 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 2^X * 4KB, where X is 

the value programmed in this register. 
When implemented, reads of this field return the value that was 

last programmed to it.
