Subject: [PATCH AUTOSEL 5.15 15/16] tools/power turbostat: fix decoding of HWP_STATUS
Date: Wed, 22 Mar 2023 16:01:19 -0400 [thread overview]
Message-ID: <20230322200121.1997157-15-sashal@kernel.org> (raw)
In-Reply-To: <20230322200121.1997157-1-sashal@kernel.org>
From: Antti Laakso <antti.laakso@intel.com>
[ Upstream commit 92c25393586ac799b9b7d9e50434f3c44a7622c4 ]
The "excursion to minimum" information is in bit2
in HWP_STATUS MSR. Fix the bitmask used for
decoding the register.
