From 34537ddd208d614dbefeb97823ae1c79e7771588 Mon Sep 17 00:00:00 2001 From: Patryk Wlazlyn Date: Tue, 10 Dec 2024 18:27:38 +0100 Subject: [PATCH] tools/power turbostat: Return default value for unmapped PMT domains When requesting PMT counters with --add command, user may want to skip specifying values for all the domains (that is, cpu, core, package etc). For the domains that user did not provide information on how to read the counter, return default value - zero.
