The Ongoing Work Of Nouveau Power Management / Re-Clocking

In addition to the Nouveau status update talk at XDC2016, Nouveau contributor Karol Herbst had carried out an additional presentation on Friday dedicated to this open-source NVIDIA driver's work on power management and re-clocking.

In the presentation he covered how the power sensors support will become "useful" in Linux 4.9, how clock gating can yield up to 25% power savings, and the ongoing work around GPU Boost. As covered previously, Nouveau will partially support GPU Boost with the Linux 4.9 kernel. There are also various other re-clocking efforts still ongoing with the project.

For some of my past testing and coverage of the recent Nouveau Boost work, see Linux 4.9 To Begin Landing Nouveau "Boost" Support For Faster Performance and Nouveau With Boost Patches Are Now Competitive To Radeon/AMDGPU With RadeonSI.
