Intel developers of the Open-Source Technology Center are working on Dynamic Refresh Rate Switching (DRRS) support for Linux.

Per the Intel developer summary, "Dynamic Refresh Rate Switching (DRRS) is a power conservation feature which enables swtiching between low and high refresh rates based on the usage scenario. This feature is applciable for internal eDP panel. Indication that the panel supports DRRS is given by the panel EDID, which would list multiple refresh rates for one resolution."

The patch series can be found on the intel-gfx mailing list and the work will hopefully be merged for the Linux 3.15 kernel merge window.
