What does Intel NPU Linux driver frequency limiting do?

It lets you set min/max clock speeds on NPU 50XX+ hardware to cut power use and tame thermals—readable on older gens too.

Will Intel NPU frequency controls work on Lunar Lake?

No, it's for Panther Lake and newer (NPU5+). Lunar's NPU4 stays read-only.

Does this mean NPUs are power hogs?

Kinda—shows they're not the effortless AI sippers Intel hyped. Throttling's now table stakes.
