/proc/cpuinfo represents online CPUs only, and the number of CPUs is limited by the 'maxcpus' option. /sys/devices/system/cpu/possible is a better option for our purpose since it represents the possible CPUs that can ever be available in the system, including the offline CPUs. And it's not limited by 'maxcpus'. Though the Linux command line parameter nr_cpus and possible_cpus still have impact on /sys/devices/system/cpu/possible.

board_parser.py will collect all board related info and then generate a board info file for acrn-config host tool usage. usage: python3 board_parser.py <board_name> [--out board_info_file] board_name : the name of board that run ACRN hypervisor, like apl-up2/nuc7i7dnb. It will be used as name of the board configurations folder which created by acrn-config host tool. board_info_file : (optional) the name of board info file. if it is not specified, a name of <board_name>.xml will be generated under ./out/ folder by default. Please run this script under native Linux environment with root privilege. OS requirement: Release: Ubuntu 18.04+ or ClearLinux 30210+ Tools: cpuid, rdmsr, lspci, dmidecode kernel cmdline: "idle=nomwait intel_idle.max_cstate=0 intel_pstate=disable"
