From b7a4706f66e5dfbb981c4f669e5b3fa92ad80fe1 Mon Sep 17 00:00:00 2001 From: Armin Wolf Date: Thu, 23 Nov 2023 01:48:18 +0100 Subject: hwmon: (dell-smm) Add support for WMI SMM interface MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some Dell machines like the Dell Optiplex 7000 do not support the legacy SMM interface, but instead expect all SMM calls to be issued over a special WMI interface. Add support for this interface so users can control the fans on those machines.
