[Qemu-devel] [PATCH v1 4/7] numa: Classify the numa nodes as memory initiators and memory targets

[Liu Jingqi]

An initiator proximity domain (memory initiator) is any device
such as a CPU or a separate memory I/O device that can initiate
a memory request. A target proximity domain (memory target)
is a CPU-accessible physical address range.
