** Description changed: [ Impact ] * Changing the Power Mode from PPD (Perfomance/Balance/Power Saver), the USTT(User Selectable Thermal Table) setting will also be changed. Add the feature to support Power Mode and ACPI platform profile sychornization. The mapping relationship PPD to platform profile: performance <-> performance balanced <-> balanced/balanced_performance/cool power saver <-> low-power/quiet [ Test Plan ] * On machine supports ACPI platform profile, which has sysfs node /sys/firmware/acpi/platform_profile - * Change the platform profile in the BIOS + * Try to modify power mode by $ sudo powerprofilectl set <power-mode> - * Boot into Ubuntu desktop and open PPD - - * The settings would be updated against the mapping - - * Try to modify power mode in PPD - - * Check if BIOS update the platform profile accordingly + * Check if BIOS update the platform profile accordingly [ Where problems could occur ] * The change tries to categorize of different strings defined in platform_profile driver If the PPD working on the platform output unexpected platform_profile string the PPD won't adjust the power mode correctly. [ Other Info ] * Upstream commit: https://gitlab.freedesktop.org/upower/power- profiles-daemon/-/commit/6b565b0b05a2bc92e3c546a567b394f415937265 * The patch is in 25.04 and 25.10 already.
