2022-08-26platform/x86: asus-wmi: Modify behaviour of Fn+F5 fan keyLuke D. Jones
Some more recent TUF laptops have both fan_boost and thermal_throttle. The key code for Fn+F5 is also different and unmapped. This patch adjusts the asus_wmi_handle_event_code() match to match for both 0x99 and 0xAE, and run both mode switch functions for fan_boost and/or thermal_throttle if either are available. It is required that both are tried, as in some instances the ACPI set-method for one may not have any code body within it even though it was returned as supported by the get method.

2022-08-25platform/x86: asus-wmi: Simplify tablet-mode-switch handlingHans de Goede
Simplify tablet-mode-switch handling: 1. The code is the same for all variants, the only difference is the dev_id and notify event code. Store the dev_id + code in struct asus_wmi and unify the handling 2. Make the new unified asus_wmi_tablet_mode_get_state() check dev_id has been set and make it a no-op when not set. This allows calling it unconditionally at resume/restore time 3. Simplify the tablet_mode_sw module-param handling, this also allows selecting the new lid-flip-rog type through the module-param.

2022-04-27platform/x86: asus-wmi: Fix driver not binding when fan curve control probe ↵Hans de Goede
fails Before this commit fan_curve_check_present() was trying to not cause the probe to fail on devices without fan curve control by testing for known error codes returned by asus_wmi_evaluate_method_buf(). Checking for ENODATA or ENODEV, with the latter being returned by this function when an ACPI integer with a value of ASUS_WMI_UNSUPPORTED_METHOD is returned. But for other ACPI integer returns this function just returns them as is, including the ASUS_WMI_DSTS_UNKNOWN_BIT value of 2. On the Asus U36SD ASUS_WMI_DSTS_UNKNOWN_BIT gets returned, leading to: asus-nb-wmi: probe of asus-nb-wmi failed with error 2 Instead of playing whack a mole with error codes here, simply treat all errors as there not being any fan curves, fixing the driver no longer loading on the Asus U36SD laptop.

The fan curve control patches introduced a regression for at least the TUF FX506 and possibly other TUF series laptops that do not have support for fan curve control. As part of the probing process, asus_wmi_evaluate_method_buf is called to get the factory default fan curve . The WMI management function returns 0 on certain laptops to indicate lack of fan curve control instead of ASUS_WMI_UNSUPPORTED_METHOD. This 0 is transformed to -ENODATA which results in failure when probing.

2021-11-16platform/x86: asus-wmi: Add support for custom fan curvesLuke D. Jones
Add support for custom fan curves found on some ASUS ROG laptops. These laptops have the ability to set a custom curve for the CPU and GPU fans via two ACPI methods. This patch adds two pwm<N> attributes to the hwmon sysfs, pwm1 for CPU fan, pwm2 for GPU fan. Both are under the hwmon of the name `asus_custom_fan_curve`. There is no safety check of the set fan curves - this must be done in userspace. The fans have settings [1,2,3] under pwm<N>_enable: 1. Enable and write settings out 2. Disable and use factory fan mode 3. Same as 2, additionally restoring default factory curve. Use of 2 means that the curve the user has set is still stored and won't be erased, but the laptop will be using its default auto-fan mode. Re-enabling the manual mode then activates the curves again. Notes: - pwm<N>_enable = 0 is an invalid setting. - pwm is actually a percentage and is scaled on writing to device.

2020-10-28platform/x86: asus-wmi: Add support for SW_TABLET_MODE on UX360Samuel Čavoj
The UX360CA has a WMI device id 0x00060062, which reports whether the lid is flipped in tablet mode (1) or in normal laptop mode (0). Add a quirk (quirk_asus_use_lid_flip_devid) for devices on which this WMI device should be used to figure out the SW_TABLET_MODE state, as opposed to the quirk_asus_use_kbd_dock_devid. Additionally, the device needs to be queried on resume and restore because the firmware does not generate an event if the laptop is put to sleep while in tablet mode, flipped to normal mode, and later awoken. It is assumed other UX360* models have the same WMI device. As such, the quirk is applied to devices with DMI_MATCH(DMI_PRODUCT_NAME, "UX360"). More devices with this feature need to be tested and added accordingly. The reason for using an allowlist via the quirk mechanism is that the new WMI device (0x00060062) is also present on some models which do not have a 360 degree hinge (at least FX503VD and GL503VD from Hans' DSTS collection) and therefore its presence cannot be relied on.

The new SW_TABLET_MODE support (naively?) assumed that non Transformer devices would either not support the 0x00120063 WMI-device-id at all, or would NOT set ASUS_WMI_DSTS_PRESENCE_BIT in their reply when querying the device-id. Unfortunately this is not true and we have received many bug reports about this change causing the asus-wmi driver to always report SW_TABLET_MODE=1 on non Transformer devices. This causes libinput to think that these are 360 degree hinges style 2-in-1s folded into tablet-mode. Making libinput suppress keyboard and touchpad events from the builtin keyboard and touchpad. So effectively this causes the keyboard and touchpad to not work on many non Transformer Asus models. This commit fixes this by using the existing DMI based quirk mechanism in asus-nb-wmi.c to allow using the 0x00120063 device-id for reporting SW_TABLET_MODE on Transformer models and ignoring it on all other models.

2020-06-01platform/x86: asus_wmi: Reserve more space for struct bias_argsChris Chiu
On the ASUS laptop UX325JA/UX425JA, most of the media keys are not working due to the ASUS WMI driver fails to be loaded. The ACPI error as follows leads to the failure of asus_wmi_evaluate_method. ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [IIA3] at bit offset/length 96/32 exceeds size of target Buffer (96 bits) (20200326/dsopcode-203) No Local Variables are initialized for Method [WMNB] ACPI Error: Aborting method \_SB.ATKD.WMNB due to previous error (AE_AML_BUFFER_LIMIT) (20200326/psparse-531) The DSDT for the WMNB part shows that 5 DWORD required for local variables and the 3rd variable IIA3 hit the buffer limit. Method (WMNB, 3, Serialized) { .. CreateDWordField (Arg2, Zero, IIA0) CreateDWordField (Arg2, 0x04, IIA1) CreateDWordField (Arg2, 0x08, IIA2) CreateDWordField (Arg2, 0x0C, IIA3) CreateDWordField (Arg2, 0x10, IIA4) Local0 = (Arg1 & 0xFFFFFFFF) If ((Local0 == 0x54494E49)) .. } The limitation is determined by the input acpi_buffer size passed to the wmi_evaluate_method. Since the struct bios_args is the data structure used as input buffer by default for all ASUS WMI calls, the size needs to be expanded to fix the problem.

2020-05-12platform/x86: asus-wmi: Add support for SW_TABLET_MODEHans de Goede
On Asus 2-in-1s with a detachable keyboard the Asus WMI interface reports if the tablet is attached to the keyboard or not. Report if the 2-in-1 is in tablet or clamshell mode to userspace by reporting SW_TABLET_MODE events to userspace. This has been tested on a T100TA, T100CHI, T100HA and T200TA.

Move the asus_wmi_input_init() and asus_wmi_input_exit() functions to below the WMI helpers, so that further patches in this patch-set can use the WMI helpers inside asus_wmi_input_init() without needing a forward declaration. Note this commit makes no functional changes, the moved block of code is completely unchanged.

2020-03-20platform/x86: asus-wmi: Support laptops where the first battery is named BATTKristian Klausen
The WMI method to set the charge threshold does not provide a way to specific a battery, so we assume it is the first/primary battery (by checking if the name is BAT0). On some newer ASUS laptops (Zenbook UM431DA) though, the primary/first battery isn't named BAT0 but BATT, so we need to support that case.

2020-01-31platform/x86: asus-wmi: switch to use <linux/units.h> helpersAkinobu Mita
The asus-wmi driver doesn't implement the thermal device functionality directly, so including <linux/thermal.h> just for DECI_KELVIN_TO_CELSIUS() is a bit odd. This switches the asus-wmi driver to use deci_kelvin_to_millicelsius() in <linux/units.h>. The format string is changed from %d to %ld due to function returned type.
