The fw_attributes_class provides a much cleaner interface to all of the
attributes introduced to asus-wmi. This patch moves all of these extra
attributes over to fw_attributes_class, and shifts the bulk of these
definitions to a new kernel module to reduce the clutter of asus-wmi
with the intention of deprecating the asus-wmi attributes in future.
The work applies only to WMI methods which don't have a clearly defined
place within the sysfs and as a result ended up lumped together in
/sys/devices/platform/asus-nb-wmi/ with no standard API.
Where possible the fw attrs now implement defaults, min, max, scalar,
choices, etc. As en example dgpu_disable becomes:
/sys/class/firmware-attributes/asus-armoury/attributes/dgpu_disable/
├── current_value
├── display_name
├── possible_values
└── type
as do other attributes.

This is kinda a big patch that I feel might have done some justice to
split into smaller logical pieces. These are much easier to review.
For example:
1) You've clearly got 3 "groups" of attributes, maybe those should come
in a separate series each.
2) Some of the helper functions that are exported should be exported in
their own patches (for example asus_wmi_get_devstate_dsts)
3) panel_hd_mode is a new attribute not leveraged from asus-wmi AFAICT,
with a new define. It probably could have been it's own patch to "add
panel_hd_mode".
More comments inline below.

Two problems:
1. Seems to be a circular depedency.
2. Selects can't have extra depends or selects (FW_ATTR_CLASS stands out).
I feel this select should just be droped.

I go back and forth on the existence of tuning knobs for all these
values. As a tinkerer it's of course nice to see so many knobs.
However thinking about how this would be exposed to userspace and what
users will drag for a "slider" for performance it's really confusing.
Which knob is tuned? What's different for CPU vs platform? What's slow
vs fast?
As a result, I think I would rather see these (specifically) relegated
to debugfs attributes and instead export an ACPI platform profile. The
ACPI platform profile can then give users a clearer set of expectations; IE:
"power-saver", "balanced", "performance"
Bifurcating it this way will enable both audiences. The people who want
to drag a slider in a UI to save power or consume power can do so, and
those that know what all these mean and want to spend more time
tinkering can go to debugfs to do so.
But with this idea there would essentially be two sets of knobs that
change the same thing. So I think that if the debugfs knobs were tuned
away from the defaults the platform profile needs to be reset to an error.

Shouldn't you only update this if no error? IE move to the end of the

Good points yeah. I've split things in to smaller more easily digestible chunks now.

I fully understand the concern here and share it. But one thing I think that should be considered is that *most* users won't be going directly to the attributes, or even be aware of them. Those that do I would hope at least know what they are or the name/desc is enough to provide hints to find more info.
And then a usersapce app exposing these should explain what they are, and be much more usable. A tangible benefit of fw_attr class is that it makes userspace apps easier to do.

This would at least address that changing these values deviates from the platform_profile, and also the system fan profile - so it puts the onus on the user to ensure the settings they use are safe to use.
My main concern is perhaps that I lose the easy to use fw_attr class. But I suppose I can also recreate the minimum of /path/attr_name/{min/max/default/current} without too much hassle.
Moving to debugfs:
pros:
- setting unsafe values moves responsibility to user
- simplifies things a little
- hides a possible danger from users
cons:
- setting unsafe values moves responsibility to user
- a userspace app then also takes on that responsibility
- loses the fw_attr class API
- makes it harder to access
For now these are moved to a new patch to make it easier to review as well as change.

Never really been clear on this myself. A massive amount of other code does include the comma so that's what I followed. And then a massive amount of other code uses the opposite so I could follow that too.. but I work in most of the asus stuff and it looks like that's what is common there so I'll remove the comma.
Many thanks for taking the time to review.

Implement the APU memory size control under the asus-armoury module using
the fw_attributes class.
This allows the APU allocated memory size to be adjusted depending on
the users priority. A reboot is required after change.

This doesn't seem right. If you requested "0", you just set APU memory
to 0GB?

What exactly is the unit for 0-8? It's obviously not a a multiple of
base memory, is it a multiple of an adder?
Is this changing the VRAM allocation? Like does 0 mean 256MB, 1 is 512 etc?

Yep.. I know it seems wrong but it's true. GHelper on windows does the same thing https://github.com/seerge/g-helper/blob/ab08bd8ab45774b3e1961ddff69b6281a2f6e733/app/AsusACPI.cs#L666

There is a log entry above that clarifying it but I thought I'd done the same here. Fixed now.

Implement Intel core enablement under the asus-armoury module using the
fw_attributes class.
This allows users to enable or disable preformance or efficiency cores
depending on their requirements. After change a reboot is required.

With the existence of the asus-bioscfg module the attributes no-longer
need to live under the /sys/devices/platform/asus-nb-wmi/ path.
Deprecate all those that were implemented in asus-bioscfg with the goal
of removing them fully in the next LTS cycle.
