Subject: [PATCH] tools/power turbostat: fix decoding of HWP_STATUS
Date: Wed, 25 Jan 2023 15:17:50 +0200 [thread overview]
Message-ID: <20230125131750.1279959-1-antti.laakso@linux.intel.com> (raw)
From: Antti Laakso <antti.laakso@intel.com>
The "excursion to minimum" information is in bit2
in HWP_STATUS MSR. Fix the bitmask used for
decoding the register.
