The amd_pmc_get_smu_version() and amd_pmc_idlemask_read() functions are used in the probe / suspend/resume code, so they are also used when CONFIG_DEBUGFS is disabled, move them outside of the #ifdef CONFIG_DEBUGFS block. Note this purely moves the code to above the #ifdef CONFIG_DEBUGFS, the code is completely unchanged.

Adds support for: - Dell Inspiron 2in1 tablet mode switch notifications. These are delivered by a type 0x0011 message with code 0xe070, followed by a flag (1 for laptop mode, 0 for tablet mode). - Recognising (but not otherwise processing) the Dell Ultra Performance mode request switch. This is delivered by a type 0x0012 message with code 0x000d, followed by a parameter that is either 1 or 2. It is not clear what (if anything) should be done with this notification, so it is ignored.

When DELL_WMI=y, DELL_WMI_PRIVACY=y, and LEDS_TRIGGER_AUDIO=m, there is a linker error since the LEDS trigger code is built as a loadable module. This happens because DELL_WMI_PRIVACY is a bool that depends on a tristate (LEDS_TRIGGER_AUDIO=m), which can be dangerous. ld: drivers/platform/x86/dell/dell-wmi-privacy.o: in function `dell_privacy_wmi_probe': dell-wmi-privacy.c:(.text+0x3df): undefined reference to `ledtrig_audio_get' Fixes: 8af9fa37 ("platform/x86: dell-privacy: Add support for Dell hardware privacy") Signed-off-by:

IdleMask is the metric used by the PM firmware to know the status of each of the Hardware IP blocks monitored by the PM firmware. Knowing this value is key to get the information of s2idle suspend/resume status. This value is mapped to PMC scratch registers, retrieve them accordingly based on the CPU family and the underlying firmware support. Co-developed-by:

The current code carries out the following ACPI status mapping: AE_NOT_FOUND -> AE_OK AE_OK -> AE_OK AE_$X -> AE_$X That is, everything is mapped to itself, except AE_NOT_FOUND. The current code does not do it in the most straighforward way. Simplify the logic. Signed-off-by:

Previously, `__query_block()` would fail if the second WCxx method call failed. However, the WQxx method might have succeeded, and potentially allocated memory for the result.

A number of upcoming notebook computer designs drive the internal display panel's backlight PWM through the Embedded Controller (EC). This EC-based backlight control can be plumbed through to an ACPI "WMAA" method interface, which in turn can be wrapped by WMI with the GUID handle 603E9613-EF25-4338-A3D0-C46177516DB7. Add a new driver, aliased to the WMAA WMI GUID, to expose a sysfs backlight class driver to control backlight levels on systems with EC-driven backlights. Signed-off-by:

This patch adds support for HP Omen laptops. It adds support for most things that can be controlled via the Windows Omen Command Center application. - Fan speed monitoring through hwmon - Platform Profile support (cool, balanced, performance) - Max fan speed function toggle Also exposes the existing HDD temperature through hwmon since this driver didn't use hwmon before this patch. This patch has been tested on a 2020 HP Omen 15 (AMD) 15-en0023dx. - V1 Initial Patch - V2 Use standard hwmon ABI attributes Add existing non-standard "hddtemp" to hwmon - V3 Fix overflow issue in "hp_wmi_get_fan_speed" Map max fan speed value back to hwmon values on read Code style fixes Fix issue with returning values from "hp_wmi_hwmon_read", the value to return should be written to val and not just returned from the function - V4 Use DMI Board names to detect if a device should use the omen specific thermal profile method. Select HWMON instead of depending on it. Code style fixes. Replace some error codes with more specific/meaningful ones. Remove the HDD temperature from HWMON since we don't know what unit it's expressed in. Handle error from hp_wmi_hwmon_init - V5 Handle possible NULL from dmi_get_system_info() Use match_string function instead of manually checking Directly use is_omen_thermal_profile() without the static variable.
