Configuration options: [Disabled] [Enabled] [Auto]
Location of private memory regions [Auto]
Controls whether or not the private memory regions (PSP, SMU, and CC6) are
at the top of DRAM or distributed. Note that distributed requires memory on
all dies. Note that it will always be at the top of DRAM id some dies don’t have
memory regardless of this option’s setting.
Configuration options: [Distributed] [Consolidated] [Consolidated to 1st DRAM

ACPI SLIT Distance Control [Auto]
This option determines how the SLIT distances are declared.
Configuration options: [Manual] [Auto]
The following items appear only when ACPI SLIT Distance Control is set to [Auto].
ACPI SLIT remote relative distance [Auto]
Allows you to set the remote socket distance for 2P systems as near (2.8) or
far (3.2).
Configuration options: [Near] [Far] [Auto]
The following items appear only when ACPI SLIT Distance Control is set to [Manual].
ACPI SLIT same socket distance [C]
Specify the distance to other physical domains within the same socket.
ACPI SLIT remote socket distance [20]
Specify the distance to domains the remote socket.
ACPI SLIT local SLink distance [32]
Specify the distance to an SLink domain on the same socket.
ACPI SLIT remote SLink distance [3C]
Specify the distance to an SLink domain on the other socket.
ACPI SLIT local inter-SLink distance [FF]
Specify the distance between two SLink domains on the same socket.
ACPI SLIT remote inter-SLink distance [FF]
