From 27d47356b6dfa92042a17a0b474f08910d4c8e8f Mon Sep 17 00:00:00 2001 From: Len Brown Date: Sat, 27 Feb 2016 00:37:54 -0500 Subject: [PATCH] tools/power turbostat: show GFXMHz Under the column "GFXMHz", show a snapshot of this attribute: /sys/class/graphics/fb0/device/drm/card0/gt_cur_freq_mhz This is an instantaneous snapshot of what sysfs presents at the end of the measurement interval. turbostat does not average or otherwise perform any math on this value.
