[PATCH v5 0/1] ARM Sbsa-ref: Enable CPU cluster topology

Posted by Xiong Yining 5 months, 2 weeks ago

Enable CPU cluster support on SbsaQemu platform, so that users can
specify a 4-level CPU hierarchy sockets/clusters/cores/threads. And this
topology can be passed to the firmware through /cpus/topology Device Tree.
