https://bugzilla.kernel.org/show_bug.cgi?id=217020 Bug ID: 217020 Summary: hp-wmi: Unable to change platform profile: Operation not supported Product: Drivers Version: 2.5 Kernel Version: 6.2.0-rc7 Hardware: Intel OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Platform_x86 Assignee: drivers_platform_x86@xxxxxxxxxxxxxxxxxxxx Reporter: luisbocanegra17b@xxxxxxxxx Regression: No Created attachment 303711 --> https://bugzilla.kernel.org/attachment.cgi?id=303711&action=edit ACPI table Hi, I have a hp omen 15-dc1004la (board 8575, latest BIOS installed) and currently can't change the thermal profile, I get this error: # echo cool > /sys/firmware/acpi/platform_profile bash: echo: write error: Operation not supported # cat /sys/firmware/acpi/platform_profile_choices cool balanced performance # cat /sys/firmware/acpi/platform_profile balanced I see no errors in dmesg I remember being able to change it before (could hear fans spin up/down) so I rebuilt older versions of the module (on top of mainline) and these are my findings: >From 4c51ba9af42dff0ef6a2ca3edcefa76f3466959e to be9d73e64957bbd31ee9a0d11adc0f720974c558 can change power profiles with the above command, but the value in /sys/firmware/acpi/platform_profile stays the same. After 4b4967cbd2685f313411e6facf915fb2ae01d796 /sys/firmware/acpi/platform_profile_choices disappears, it comes back on dc6a6ab58379f25bf991d8e4a13b001ed806e881 but I get the Operation not supported error, same until HEAD(ce95010ef62d4bf470928969bafc9070ae98cbb1). Attached a ACPI dump in case that's useful. I'm not a developer so that's all the information I can give at the moment, but I'm open to provide more information if needed, also testing patches to debug/test this bug. -- You may reply to this email to add a comment.
