Subject: [PATCH] platform/x86: hp-wmi: add support for quiet thermal profile

The quiet profile is available only on models without dGPU,
so we enable it when the device has only one GPU onboard.

Thank you for your patch.

I have just landed a very similar patch form Jorge from HP:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/commit/?h=for-next&id=00b1829294b7c88ecba92c661fbe6fe347b364d2

The first 3 hunks of the patch are the same, only the conditions
under which the:

set_bit(PLATFORM_PROFILE_QUIET, platform_profile_handler.choices);

call is made are different, Jorge's patch does this essentially like this:

if (!is_omen_thermal_profile())
set_bit(PLATFORM_PROFILE_QUIET, platform_profile_handler.choices);

which seems a bit cleaner to me and hopefully works just as well
or maybe even better.

Regards,

Hans

Sorry for the duplicate I hadn’t seen Jorge’s patch.

The only thing I want to point out is that in this way the patch
enables a quiet profile on my non-omen notebook (HP Spectre x360 15-
df0006nl) that doesn't support it or at least the HP Command Center app
on windows doesn't offer it as choice.

Maybe this is a bug in windows implementation, if Jorge can kindly give
a feedback on this.

Regards,
Elia
