            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

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.

--- Comment #1 from Luis Bocanegra (luisbocanegra17b@gmail.com) ---
So tried to debug this issue the best I could and these are my findings
omen_get_thermal_policy_version() (HPWMI_GET_SYSTEM_DESIGN_DATA) reads as 0x03,
same as windows using ec-probe tool

Bypassing the return in omen_get_thermal_policy_version()
seems to allow platform_profile_omen_set() to change the power profile, at
least with 
cool because I hear the fans spin up and then down when setting balanced, just
like the gaming hub on windows

But omen_thermal_profile_get() (HP_OMEN_EC_THERMAL_PROFILE_OFFSET) always 
returns 0 making the sysfs entry always stay on balanced and breaking the
funcionality of power-profiles-daemon

Here the logs of changing to cool then performance profiles

[Thu Apr 13 21:29:40 2023] hp_wmi: omen_thermal_profile_get > data = 0x0
[Thu Apr 13 21:29:42 2023] hp_wmi: platform_profile_omen_set > profile = 0x1
[Thu Apr 13 21:29:42 2023] hp_wmi: omen_get_thermal_policy_version > ret = 0x3
[Thu Apr 13 21:29:42 2023] hp_wmi: omen_get_thermal_policy_version > buffer[3]
= 0x0 //bypassed
[Thu Apr 13 21:29:42 2023] hp_wmi: omen_thermal_profile_set 2 > ret = 0x0
[Thu Apr 13 21:29:43 2023] hp_wmi: omen_thermal_profile_get > data = 0x0
[Thu Apr 13 21:29:49 2023] hp_wmi: platform_profile_omen_set > profile = 0x5
[Thu Apr 13 21:29:49 2023] hp_wmi: omen_get_thermal_policy_version > ret = 0x3
[Thu Apr 13 21:29:49 2023] hp_wmi: omen_get_thermal_policy_version > buffer[3]
= 0x0
[Thu Apr 13 21:29:49 2023] hp_wmi: omen_thermal_profile_set 1 > ret = 0x0
[Thu Apr 13 21:29:52 2023] hp_wmi: omen_thermal_profile_get > data = 0x0

Is this a very edge case bug or the controller somehow broken? Happy to provide
more information/test patches as needed.

Looking at the registers on windows the HP_OMEN_EC_THERMAL_PROFILE_OFFSET
(0x95) doesn't change on windows when switching modes either, could it be that
the gaming hub is doing something different or straight up ignoring the
readings due to a bug in firmware?

Here is an updated log with more debug prints:
