Processor Configuration Registers
4RO 0bUncore
Required Write-Buffer Flushing (RWBF)
0 = No write-buffer flushing is needed to ensure changes to
memory-resident structures are visible to hardware.
1 = Software must explicitly flush the write buffers to ensure
updates made to memory-resident remapping structures are
visible to hardware.
3RO 0bUncore
Advanced Fault Logging (AFL)
0 = Advanced fault logging is not supported. Only primary fault
logging is supported.
1 = Advanced fault logging is supported.
2:0 RO 010b Uncore
Number of domains supported (ND)
000 = Hardware supports 4-bit domain-ids with support for up to
16 domains.
001 = Hardware supports 6-bit domain-ids with support for up to
64 domains.
010 = Hardware supports 8-bit domain-ids with support for up to
256 domains.
011 = Hardware supports 10-bit domain-ids with support for up
to 1024 domains.
100 = Hardware supports 12-bit domain-ids with support for up
to 4K domains.
100 = Hardware supports 14-bit domain-ids with support for up
to 16K domains.
110 = Hardware supports 16-bit domain-ids with support for up
to 64K domains.
111 = Reserved.
