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.
