From: Armin Wolf Date: Thu, 10 Apr 2025 16:54:54 +0000 (+0200) Subject: ACPI: OSI: Stop advertising support for "3.0 _SCP Extensions" X-Git-Tag: v6.16-rc1~162^2~5 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8cf4fdac9bdead7bca15fc56fdecdf78d11c3ec6;p=thirdparty%2Flinux.git ACPI: OSI: Stop advertising support for "3.0 _SCP Extensions" As specified in section 5.7.2 of the ACPI specification the feature group string "3.0 _SCP Extensions" implies that the operating system evaluates the _SCP control method with additional parameters. However the ACPI thermal driver evaluates the _SCP control method without those additional parameters, conflicting with the above feature group string advertised to the firmware thru _OSI. Stop advertising support for this feature string to avoid confusing the ACPI firmware.
