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.
