From 5d76958de124af3877f9b399a4ec8a6377fe4ffd Mon Sep 17 00:00:00 2001 From: Andrey Petrov Date: Thu, 23 Apr 2020 10:54:18 -0700 Subject: soc/intel/xeon_sp/cpx: Calculate number of threads based on sockets Assuming given system is populated with multiple CPUs of same SKUs, calculate number of threads based on MAX_SOCKET. This is a stop gap solution until proper way of identifying total number of sockets is determined.
