platform/x86: hp-bioscfg: Fix class device unregistration

2025-06-30T09:12:13Z

Devices under the firmware_attributes_class do not have unique a dev_t. Therefore, device_unregister() should be used instead of device_destroy(), since the latter may match any device with a given dev_t.

platform/x86: hp-bioscfg: Replace deprecated strncpy() with strscpy()

2025-03-03T12:57:32Z

Since kstrtol() requires a NUL-terminated string as input and strncpy() is deprecated for NUL-terminated destination buffers, use strscpy() instead. Compile-tested only.

platform/x86: hp: Use -y instead of -objs in Makefile

2025-02-24T15:15:04Z

The `objs` suffix is reserved for user-space tools. Use the `y` suffix instead, which is usually used for kernel drivers.

platform/x86: hp-bioscfg: Use wmi_instance_count()

2025-02-24T11:19:18Z

The WMI core already knows the instance count of a WMI guid. Use this information instead of querying all possible instances which is slow and might be unreliable.

platform/x86: hp-wmi: Add fan and thermal profile support for Victus 16-s1000

2025-01-20T12:13:14Z

The following patch adds support for HP Victus 16-s1000 laptop series, by adding and fixing the following functionalities, which can be accessed through hwmon and platform_profile sysfs: - Functional measured fan speed reading - Ability to enable and disable maximum fan speed - Platform profiles full setting ability for CPU and GPU It sets appropriates CPU and GPU power settings both on AC and battery power sources, for low-power, balanced and performance modes. It has been thoroughly tested on a 16-s1034nf laptop based on a 8C9C DMI board name, and behavior of the driver on previous boards is left untouched thanks to the separated lists of DMI board names.

ACPI: platform_profile: Remove platform_profile_handler from exported symbols

2025-01-17T17:15:59Z

In order to protect the platform_profile_handler from API consumers, allocate it in platform_profile_register() and modify it's signature accordingly. Remove the platform_profile_handler from all consumer drivers and replace them with a pointer to the class device, which is now returned from platform_profile_register(). Replace *pprof with a pointer to the class device in the rest of exported symbols.

ACPI: platform_profile: Add `probe` to platform_profile_ops

2025-01-16T15:26:30Z

Add a `probe` callback to platform_profile_ops, which lets drivers initialize the choices member manually. This is a step towards unexposing the struct platform_profile_handler from the consumer drivers.
