Optimizing Software Applications for Power: Part 2 (of 13)

Part 2: Hardware Platform Power States

On a hardware platform level, ACPI defines a set of power states pertaining to various aspects of the system: global system states (Gx) like “off” and “working”, sleep states (Sx), device power states (Dx), processor power states (Cx), device and processor performance states (Px), and throttling states (Tx). Of interest to this discussion are C-states and P-states.

Sun + Intel + OpenSolaris + 2 Years = The Year of Core

Today is the second anniversary of the Sun and Intel joint agreement to optimize the Solaris operating system for Intel Xeon processors. Like last year, when I wrote this summary of our work, I decided to recap where we are to date.

Like last year’s edition, this is pretty much off the top of my head.

OpenSolaris and Centrino 2

Last summer, Intel launched our latest mobile computing platform, branded Intel Centrino 2 processor technology. For a long time as we were doing OpenSolaris development, I used to know this platform by its codename "Montevina", but that's all history now. Long live Centrino 2!

This new mobile platform has some great features, like a multi-core processor, great battery life, new graphics and wireless technologies.
