From 0de6c0df4ecc32ffaf064fea3a43846ba4474bd0 Mon Sep 17 00:00:00 2001 From: Len Brown Date: Wed, 15 Feb 2017 21:45:40 -0500 Subject: [PATCH] tools/power turbostat: use wide columns to display large numbers When a counter overlfows 7 columns, it shifts the remaining columns to the right, so they no longer line up under their column header. Update turbostat to dectect when it is handling large numbers, and switch to wider columns where, necessary.
