The Linux kernel contains multiple energy-saving features. Some of them act on the system as a whole while the others are concerned with individual processors or I/O devices. The majority of them have been developed in isolation and they work reasonably well individually, but that is often insufficient to address problems related to the progressing integration of hardware and growing user expectations. For this reason, it will be necessary to make them work more closely together and I am going to talk about that in my presentation. I will describe the current status of the kernel's energy-saving features, the most important problems they are facing and some possible ways to address those problems.
The presentation should be comprehensible to everyone interested in the Linux kernel at a reasonably high level, although basic knowledge of the kernel's internals is recommended.
Software Engineer, Intel OTC
I am the maintainer of the Linux kernel's core power management code (PM core), cpuidle, cpufreq, and the ACPI subsystem. I work at Intel Open Source Technology Center as a Software Engineer with focus on the Linux kernel. I have been actively contributing to the Linux kernel since January 2005, working on the suspend and hibernate subsystem, on power management in general (including runtime PM, PM QoS etc.), and on the ACPI and PCI subsystems.
