While the terms to refer to CPU topology levels are originally borrowed from MSR listings in SDMs (i.e. thread, core, die and package), we now align the topology information with the CPUID topology enumeration leaf (which does not have a "package" level) in the implementation. However, some hard-coded level types are not updated accordingly, leading to strangely organized nodes in the generated board XML. This patch refines the CPU extractor of the board inspector by removing such hard code. Also the XPATH counting the total number of threads is refined to tolerate the variance of reported intermediate levels. Tracked-On: #6689 Signed-off-by: Junjie Mao <junjie.mao@intel.com>
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_inspector.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 the current working directory by default. Please run this script under native Linux environment with root privilege. OS requirement: Release: Ubuntu 18.04+ Tools: cpuid, rdmsr, lspci, lxml, dmidecode (optional) kernel cmdline: "idle=nomwait iomem=relaxed intel_idle.max_cstate=0 intel_pstate=disable"
