When changing the thermal policy using the platform profile API,
a Vivobook thermal policy is stored in throttle_thermal_policy_mode.
However everywhere else a normal thermal policy is stored inside this
variable, potentially confusing the platform profile.
Fix this by always storing normal thermal policy values inside
throttle_thermal_policy_mode and only do the conversion when writing
the thermal policy to hardware.

the original patch that i submitted did actually have the remapping
of the different fan profiles in the throttle_thermal_policy_write() methods
because it was the cleaner solution [1]. however after having a discussion with luke,
he shared that he might be planning to remove the throttle_thermal_policy sysfs interface
in favour of platform_profiles [2] because of a refactoring he had been working on.
currently to control fan profiles through this driver you could use
either /sys/devices/platform/asus-nb-wmi/throttle_thermal_policy
(redundant and might get removed in the future) or through platform profiles which is the
better way of doing things.
for the reasons mentionned above, I decided to keep
throttle_therma_policy_write() unchanged and to move the remapping logic
to the asus_wmi_platform_profile_set(). this adopts the approach of
having a logical mapping stored in asus_wmi struct that has to be
converted to a physical mapping whenever needed [3].
so, if luke thinks that this won't cause any merge conflicts with his
work [4] then i see no problem with this approach even though it might cause an
order change when calling throttle_thermal_policy_switch_next()

Ok, i will wait for Luke to give feedback on this series. In my opinion the order change is
ok since users likely expect the "old" Asus switching order.

Talking about throttle_thermal_policy_switch_next() we also
have platform_profile_cycle() and since asus-wmi supports
platform-profiles now I'm wondering if it would not be better
to simply completely drop throttle_thermal_policy_switch_next()
and call platform_profile_cycle() instead?
This will also keep the cycle order the same for "normal" vs
vivo even after Armin's patch.
Anyways I'll go and apply patch 1/2 to pdx86/fixes since that one is
obviously correct and fixes th Lunar Lake performance issues.
And we can keep discussing what to do wrt 2/2 and maybe also drop
throttle_thermal_policy_switch_next() if favor of
platform_profile_cycle().

Hans

Good idea, using platform_profile_cycle() would also solve a potential locking issue here.

You say "potentially confusing the platform profile", but did you
spot any actual issues when reviewing the code ?

The problem with this approach is that it changes the order in which
we step through the modes in throttle_thermal_policy_switch_next()
after this change we have:
Normal Asus: balanced -> performance -> silent -> balanced -> etc.
Vivobook: balanced -> silent -> performance -> balanced -> etc.
where if we see "silent" as lower performance then the other 2,
the vivobook order is a bit weird.
I wonder if this is a big enough issue to really worry about it
though; and I do like the cleanup / simpler code.
Note that this also causes a behavior change in
fan_curve_get_factory_default() as I mentioned in my cover-letter.
I think that that behavior change might be a good thing to do actually,
but at a minimum it needs to be documented in the commit msg.

Hans

Yes, for example:
1. User sets thermal policy to "1" (overboost) through the throttle_thermal_policy sysfs attr.
2. "1" gets stored inside throttle_thermal_policy_mode.
3. Platform profile will now think that ASUS_THROTTLE_THERMAL_POLICY_SILENT_VIVO (1) is set.
4. Platform profile reports current mode as PLATFORM_PROFILE_QUIET.
=> error!

I think users expect the normal Asus switching behavior, but you are right
that this change should be explained inside the commit message.

Since fan_curve_get_factory_default() was introduced before commit bcbfcebda2cb,
i think this patches actually fixes the behavior of this function.

I will wait till the maintainer of asus-wmi can clarify whether or not
fan_curve_get_factory_default() expects normal Asus thermal policy values
or not.
Once we resolved this i will send an updated series.
