Memory Addressing
NUMA nodes per socket [Auto]
Specifies the number of desired NUMA nodes per socket. Zero will attempt to
interleave the two sockets together.
Configuration options: [NPS0] [NPS1] [NPS2] [NPS4] [Auto]
Memory interleaving [Auto]
This items allows for disabling memory interleaving. Note that NUMA nodes per socket
will be honored regardless of this setting.
Configuration options: [Disabled] [Auto]
Memory interleaving size [Auto]
This item controls the memory interleaving size. The valid values are AUTO, 256 bytes,
512 bytes, 1 Kbytes, or 2 Kbytes. This also determines the starting address of the
interleave (bit 8, 9, 10, or 11).
Configuration options: [256 Bytes] [512 Bytes] [1 KB] [2 KB] [Auto]
1TB remap [Auto]
Attempt to remap DRAM out of the space just below the 1TB boundary. The ability to
remap depends on DRAM configuration, NPS, and interleaving selection, and may not
always be possible.
Configuration options: [Do not remap] [Attempt to remap] [Auto]
DRAM map inversion [Auto]
Inverting the map will cause the highest memory channels to get assigned the lowest
addresses in the system.
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 if some dies don’t have memory regardless of this
option’s setting.
Configuration options: [Distributed] [Consolidated] [Auto]
Disable DF to external IP SyncFloodPropagation [Auto]
This item allows you to disable SyncFlood to UMC & downstream slaves.
Configuration options: [Sync flood disabled] [Sync flood enabled] [Auto]
Disable DF sync flood propagation [Auto]
Configuration options: [Sync flood disabled] [Sync flood enabled] [Auto]
Freeze DF module queues on error [Auto]
Configuration options: [Disabled] [Enabled] [Auto]
CC6 memory region encryption [Auto]
This item allows you to control whether or not the CC6 save/restore memory is encrypted.
Configuration options: [Disabled] [Enabled] [Auto]
