.TH SMTSTATE 8 "January 2020" Linux "Linux on Power Service Tools"
.SH NAME
smtstate \- Save and restore the current SMT state
.SH SYNOPSIS
.B /usr/sbin/smtstate [ option ]
.SH DESCRIPTION
The
.I smtstate
script is used to persist the current SMT state and to restore it at a convenient time. The idea behind it is to use the script together with a systemd service to save SMT state at any shutdown event and to restore it at an early stage of the boot process. Such implementation creates a way to persist the SMT state across reboots, without requiring any other configuration from system administrators.
