2023-10-25platform/x86: asus-wmi: Only map brightness codes when using asus-wmi ↵Hans de Goede1-11/+4
backlight control commit a5b92be2482e5f9ef30be4e4cda12ed484381493 upstream. Older Asus laptops change the backlight level themselves and then send WMI events with different codes for different backlight levels. The asus-wmi.c code maps the entire range of codes reported on brightness down keypresses to an internal ASUS_WMI_BRN_DOWN code: define NOTIFY_BRNUP_MIN 0x11 define NOTIFY_BRNUP_MAX 0x1f define NOTIFY_BRNDOWN_MIN 0x20 define NOTIFY_BRNDOWN_MAX 0x2e if (code >= NOTIFY_BRNUP_MIN && code <= NOTIFY_BRNUP_MAX) code = ASUS_WMI_BRN_UP; else if (code >= NOTIFY_BRNDOWN_MIN && code <= NOTIFY_BRNDOWN_MAX) code = ASUS_WMI_BRN_DOWN; This mapping is causing issues on new laptop models which actually send 0x2b events for printscreen presses and 0x2c events for capslock presses, which get translated into spurious brightness-down presses. This mapping is really only necessary when asus-wmi has registered a backlight-device for backlight control. In this case the mapping was used to decide to filter out the keypresss since in this case the firmware has already modified the brightness itself and instead of reporting a keypress asus-wmi will just report the new brightness value to userspace. OTOH when the firmware does not adjust the brightness itself then it seems to always report 0x2e for brightness-down presses and 0x2f for brightness up presses independent of the actual brightness level. So in this case the mapping of the code is not necessary and this translation actually leads to spurious brightness-down presses being send to userspace when pressing printscreen or capslock. Modify asus_wmi_handle_event_code() to only do the mapping when using asus-wmi backlight control to fix the spurious brightness-down presses.

[ Upstream commit fdcc0602d64f22185f61c70747214b630049cc33 ] Commit 1ea0d3b46798 ("platform/x86: asus-wmi: Simplify tablet-mode-switch handling") unified the asus-wmi tablet-switch handling, but it did not take into account that the value returned for the kbd_dock_devid WMI method is inverted where as the other ones are not inverted. This causes asus-wmi to report an inverted tablet-switch state for devices which use the kbd_dock_devid, which causes libinput to ignore touchpad events while the affected T10x model 2-in-1s are docked. Add inverting of the return value in the kbd_dock_devid case to fix this.

2022-09-03platform/x86: asus-wmi: Drop DMI chassis-type check from backlight handlingHans de Goede1-7/+0
Remove this check from the asus-wmi backlight handling: /* Some Asus desktop boards export an acpi-video backlight interface, stop this from showing up */ chassis_type = dmi_get_system_info(DMI_CHASSIS_TYPE); if (chassis_type && !strcmp(chassis_type, "3")) acpi_video_set_dmi_backlight_type(acpi_backlight_vendor); This acpi_video_set_dmi_backlight_type(acpi_backlight_vendor) call must be removed because other changes in this series change the native backlight drivers to no longer unconditionally register their backlight. Instead these drivers now do this check: if (acpi_video_get_backlight_type(false) != acpi_backlight_native) return 0; /* bail */ So leaving this in place can break things on laptops with a broken DMI chassis-type, which would have GPU native brightness control before the addition of the acpi_video_get_backlight_type() != native check. Removing this should be ok now, since the ACPI video code has improved heuristics for this itself now (which includes a chassis-type check). Signed-off-by: Hans de Goede <hdegoede@redhat.com>

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.

2022-02-05platform/x86: asus-wmi: Fix regression when probing for fan curve controlHans de Goede1-1/+1
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. Jones1-5/+562
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.

Because throttle_thermal_policy is used by platform_profile and is writeable separately to platform_profile any userspace changes to throttle_thermal_policy need to notify platform_profile. In future throttle_thermal_policy sysfs should be removed so that only one method controls the laptop power profile. Signed-off-by: Luke D.

2021-08-12asus-wmi: Add dgpu disable methodLuke D. Jones1-0/+98
In Windows the ASUS Armory Crate program can enable or disable the dGPU via a WMI call. This functions much the same as various Linux methods in software where the dGPU is removed from the device tree. However the WMI call saves the state of dGPU (enabled or not) and this then changes the dGPU visibility in Linux with no way for Linux users to re-enable it. We expose the WMI method so users can see and change the dGPU ACPI state. Signed-off-by: Luke D.

2020-10-28platform/x86: asus-wmi: Add support for SW_TABLET_MODE on UX360Samuel Čavoj1-0/+40
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.
