Intel Dynamic Platform and Thermal Framework (DPTF) participants
ACPI helpers for Intel's Dynamic Platform and Thermal Framework, which exposes power and thermal "participants" (battery power limits, PCH voltage regulator controls, and similar) on Intel laptops and tablets so the OS can balance performance, power draw, and skin temperature. Present on most Intel client systems from roughly the last decade through current 2025 platforms.
recommendation
It should stay because the hardware is still being sold and the code is under active development: in late 2025 Intel posted patches enabling DPTF on its upcoming Nova Lake platform, and Google contributors are refactoring the INT340X enumeration into modules. There is no deprecation signal, and the ACPI IDs it binds (INT3407, INT3532, and several INTC10xx parts) are widely present in Intel laptops in the field.

LKDDb shows CONFIG_DPTF_POWER remains present through current mainline/HEAD and binds ACPI IDs INT3407 and INT3532.

Intel community thread includes a February 17, 2025 user report on Windows 11 with DPTF participant devices, evidencing an ongoing installed base on Intel laptops.
codex reasoning notes (technical)
Real driver: Kconfig/Makefile plus module_platform_driver() in 2 .c files. `lore_file_timeline` on dptf_power.c and dptf_pch_fivr.c showed substantial 2025 traffic, including Nova Lake enablement and INT340X modularization; no removal-series signal surfaced. LKDDb URLs were obtained via web search and confirm the configs are still carried in current kernels. The Intel Community URL was obtained via web search and is used only as installed-base evidence. `hardware_still_sold_new_in_2025=true` is an inference from late-2025 upstream enablement for new Intel platforms; deployments are not universal, but still meaningful on Intel client systems exposing these ACPI participant IDs.
