+#!/bin/bash
+#
+# This test runs on Intel x86 based hardware which support the intel_pstate
+# driver. The test checks the frequency settings from the maximum turbo
+# state to the minimum supported frequency, in decrements of 100MHz. The
+# test runs the aperf.c program to put load on each processor.
+#
+# The results are displayed in a table which indicate the "Target" state,
+# or the requested frequency in MHz, the Actual frequency, as read from
+# /proc/cpuinfo, the difference between the Target and Actual frequencies,
+# and the value of MSR 0x199 (MSR_IA32_PERF_CTL) which indicates what
+# pstate the cpu is in, and the value of
+# /sys/devices/system/cpu/intel_pstate/max_perf_pct X maximum turbo state
+#
+# Notes: In some cases several frequency values may be placed in the
+# /tmp/result.X files. This is done on purpose in order to catch cases
+# where the pstate driver may not be working at all. There is the case
+# where, for example, several "similar" frequencies are in the file:
+#
+#
+#/tmp/result.3100:1:cpu MHz : 2899.980
+#/tmp/result.3100:2:cpu MHz : 2900.000
+#/tmp/result.3100:3:msr 0x199: 0x1e00
+#/tmp/result.3100:4:max_perf_pct 94
+#
+# and the test will error out in those cases. The result.X file can be checked
+# for consistency and modified to remove the extra MHz values. The result.X
+# files can be re-evaluated by setting EVALUATE_ONLY to 1 below.
