NAME

lscpu - CPU architecture information helper  

SYNOPSIS

lscpu [-hp]  

DESCRIPTION

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

OPTIONS

-h, --help
Print a help message.
-p, --parse
Print out in parsable instead of printable format.
-x, --hex
Use hexadecimal masks for CPU(s) sets (e.g. 0x3). The default is print the sets in the 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 kernel reports wrong data.
