From 4c2122d42116ebaa1665ad0fbef2c558fdc0e3c6 Mon Sep 17 00:00:00 2001 From: Len Brown Date: Wed, 6 Jun 2018 17:44:48 -0400 Subject: [PATCH] tools/power turbostat: add optional APIC X2APIC columns Add APIC and X2APIC columns to the topology section. They are disabled-by-default -- enable like so: --debug or --enable APIC,X2APIC Signed-off-by: Len Brown --- tools/power/x86/turbostat/turbostat.8 | 2 +- tools/power/x86/turbostat/turbostat.c | 75 ++++++++++++++++++++++++--- 2 files changed, 68 insertions(+), 9 deletions(-) diff --git a/tools/power/x86/turbostat/turbostat.8 b/tools/power/x86/turbostat/turbostat.8 index ca9ef7017624..d39e4ff7d0bf 100644 --- a/tools/power/x86/turbostat/turbostat.8 +++ b/tools/power/x86/turbostat/turbostat.8 @@ -56,7 +56,7 @@ name as necessary to disambiguate it from others is necessary.
