Subject: Re: [PATCH] dell-smm-hwmon.c: Add XPS 9570 to supported devices list
Date: Wed, 28 Nov 2018 12:30:31 +0000 [thread overview]
Message-ID: <fee13b89-90d1-0c62-84f1-4f282ca36c61@autistici.org> (raw)
In-Reply-To: <20181127230637.8673-1-michelesr@autistici.org>
The output of sensors related to the is:
dell_smm-virtual-0
Adapter: Virtual device
fan1: 0 RPM
fan2: 0 RPM
This suggests that temperature sensors are not discovered.
Speeds reported in the hwmon interface are consistent with the others.
