Optimizing Chromium Low-Power Workloads on Intel Notebooks

Explore a prototype implementation of the Energy Quality of Service (EQOS) API for optimizing low-power workloads in Chromium on Intel notebooks. Learn about the results of discussions from LPC 2022 and how this API enables user-space applications to inform the kernel about their energy efficiency requirements. Discover how the prototype demonstrates significant power savings during video playback and video conferencing without compromising performance. Understand the two main ways the EQOS API differentiates tasks: utilizing Intel's Hardware Performance-State "Energy Performance Preference" setting and influencing the scheduler's ASYM-PACKING feature. Gain insights into the potential benefits of per-task EQOS class implementation across different hardware architectures and consider the unaddressed aspects of latency preferences in relation to EQOS.
