Hello!

I rebased these series on top of review-ilpo-next branch to pick up
platform_profile latest changes.

v3->v4:
  - First 6 patches are already applied so they are not included

[01/14]
  - Reordered some lines in alienfx_probe() for aesthetic purposes

[10/14]
  - Removed pr_fmt from header file

[11/14]
  - Copy pr_fmt to each linked file

[PATCH v4 01/14] platform/x86: alienware-wmi: Add a state container for LED control feature

[Kurt Borja]

Add a state container for the "alienware-wmi" platform device and
initialize it on the new alienfx_probe(). Migrate all LED control functions
to use this state container, as well as hdmi, amplifier, deepslp group
visibility methods, to support upcoming file split.

Additionally move the led_classdev registration to the platform driver
probe and make it device managed.

Drop alienware_zone_init() and alienware_zone_exit() because they are no
longer needed.

Where does this patch touch the visibility methods of the attribute groups?

[PATCH v4 02/14] platform/x86: alienware-wmi: Add WMI Drivers

[Kurt Borja]

Add WMI drivers for LEGACY and WMAX devices.

This involves moving platform driver and device registration to a helper
function, which is now called from the driver's preferred WMI device
driver probe. However this is only done if !quirks->thermal because
newer WMAX interface doesn't support any of the features exposed by this
device.

Only one driver is registered on module initialization to prevent
registering duplicate platform driver and device.

Additionally, create_thermal_profile() now takes wmi_device * instead of
platform_device *.

Can you register this platform driver during module initialization? Otherwise we might encounter
a kernel crash should a WMI driver probe multiple devices and thus calling this method more than once.

Please note however that platform_device_register_data() can be called multiple times (it simply returns
an error should the "alienware-wmi" device already exist).

Please make this device id table const.

Other than that the code looks promising.

Makes sense, I will register it on module init.

That's good to know. Then it should be ok to set .no_singleton = true
after the above change.

[PATCH v4 03/14] platform/x86: alienware-wmi: Add a state container for thermal control methods

[Kurt Borja]

Refactor all thermal control methods to use the newly defined awcc_priv
state container instead of global variables. While at it, rename
create_thermal_profile to alienware_awcc_setup and use it to set up the
WMI device "awcc" driver data.

[PATCH v4 04/14] platform/x86: alienware-wmi: Refactor LED control methods

[Kurt Borja]

Both WMI devices handled by this module specify a distinct interface for
LED control. Previously this module handled this by dynamically adapting
arguments passed to wmi_evaluate_method() based on the `interface`
global variable.

To avoid the use of global variables, and enable the migration to
non-deprecated WMI methods, let the WMI drivers define upd_led and
upd_brightness operations, which completely replace
alienware_update_led() and wmax_brightness().

Also define alienware_wmi_command(), which serves as a wrapper for
wmidev_evaluate_method(). This new method is very similar to
alienware_wmax_command() but is WMI device agnostic.

Please return an error here if out_data is true but obj is NULL or not of ACPI_TYPE_INTEGER.

[PATCH v4 05/14] platform/x86: alienware-wmi: Refactor hdmi, amplifier, deepslp methods

[Kurt Borja]

Refactor show/store methods for hdmi, amplifier, deepslp sysfs groups to
use alienware_wmi_command() instead of alienware_wmax_command() which
uses deprecated WMI methods.

[PATCH v4 06/14] platform/x86: alienware-wmi: Refactor thermal control methods

[Kurt Borja]

Refactor thermal control methods to use alienware_wmi_command() instead
of alienware_wmax_command().

Drop alienware_wmax_command() as there is no more users left.

[PATCH v4 07/14] platform/x86: alienware-wmi: Split DMI table

[Kurt Borja]

Split thermal features into a new DMI table to support upcoming file
split. While at it:

Rename quirk_entry -> alienfx_features,
Rename quirks -> alienfx

and change hdmi_mux, amplifier and deepslp types to bool, because they are
already being implicitly used as bools.

[PATCH v4 11/14] platform/x86: Split the alienware-wmi driver

[Kurt Borja]

Split alienware-wmi WMI drivers into different files. This is done
seamlessly by copying and pasting, however some blocks are reordered.

So far i am quite pleased with the current state of the patch series. The issues
i found a relatively minor. I am already looking forward to reviewing the (hopefully
final) v5 patch series :).

Besides that: Did you test this changes on a real Alienware machine?

Thanks,
Armin Wolf

Hi Armin,

Hopefully.

Thank you so much for your work on this :)

>

Yes, this was tested on an Alienware x15 R1. I tested all quirks
including those that are not supported by my machine, of course WMAX
would return err on those.
