NAME
       lscpu - CPU architecture information helper

SYNOPSIS
       lscpu [-hpx] [-s directory]

DESCRIPTION
       lscpu gathers CPU architecture information like number of CPUs, threads, cores, sockets, NUMA nodes, information about CPU caches, CPU fam-
       ily, model, bogoMIPS, byte order and stepping from sysfs and /proc/cpuinfo, and prints it in a human-readable  format.	It  supports  both
       online  and  offline  CPUs.  It can also print out in a parsable format, including how different caches are shared by different CPUs, which
       can be fed to other programs.

OPTIONS
       -h, --help
	      Print a help message.

       -p, --parse
	      Print out in parsable instead of human-readable format.

       -s, --sysroot directory
	      Use the specified directory as system root.  This allows you to inspect a snapshot from a different system.

       -x, --hex
	      Use hexadecimal masks for CPU sets (e.g. 0x3).  The default is to print the sets in list format (e.g. 0,1).

BUGS
       The basic overview about CPU family, model, etc. is always based on the first CPU only.

       Sometimes in Xen Dom0 the kernel reports wrong data.
