From: Xiong Yining <xiongyining1...@phytium.com.cn>
To align the CPU topology information recognized by the operating system
with the CPU topology information configured by QEMU, we need to make
use of the CPU topology information to create complex PPTT tables
setups.
We can get the CPU topology information via SMC.
