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.
