[Feature request] PCIe compression for cards running over PCIe x1?

Hello,

It is my understanding that nVidia drivers on Windows can compress PCIe traffic if the card is running over an x1 PCIe link and if a supported Intel integrated GPU is installed (so-called Optimus compression).

This compression can improve performance by as much as 300%. This is something that many external GPU users depend on for maximizing GPU performance in Windows. Would it be possible to enable the same functionality in the Linux driver as well?
