Intel's LPMD "Low Power Mode Daemon" Now Identifies As The "Energy Optimizer"

The Intel LPMD open-source project is a user-space daemon for optimizing active idle power handling on Linux and can be useful particularly for modern Intel Core hybrid processors. LPMD is short for the "Low Power Mode Daemon" while with today's v0.0.7 release it's now re-identified itself as the "Energy Optimizer" instead.

The Low Power Mode Daemon name is quite straight-forward and especially with the "LPMD" mentions in the binary names and throughout the project. The first noted change though with the LPMD v0.0.7 release is adopting the Energy Optimizer name:
Change lpmd description from "Low Power Mode Daemon" to "Energy Optimizer (lpmd)" because it covers more scenarios.

Though as of writing the README and other assets still note LPMD as the Low Power Mode Daemon and haven't transitioned to the Energy Optimizer.

Among the technical changes in LPMD v0.0.7 is the new "--ignore-platform-check" option to allow overriding the platform check so that the daemon will launch on unvalidated hardware platforms. There are also Autotool build system improvements and various fixes in this new version.

Downloads and more details on the LPMD Energy Optimizer v0.0.7 release via GitHub. I've been meaning to run some benchmarks showing the power and performance impact to LPMD on modern Intel Core hardware, which given the timing I may end up doing after the Lunar Lake laptop testing gets underway.
