Intel Rewrites TurboStat Plus IVB CPU Idle Support
Phoronix: Intel Rewrites TurboStat Plus IVB CPU Idle Support
Another one of the pulls going into the Linux 3.6 kernel this week is the ACPI and power management updates courtesy of Intel. The two prominent changes for this next Linux kernel release is a rewrite of the "turbostat" tool and the "intel_idle" CPU idle driver now supports Ivy Bridge processors...
Would be nice if you could measure intel_idle on Ivy Bridge. Kernel 3.5 will be on Ubuntu 12.10 so it will be almost a year from Ivy Bridge release to users getting this new code.
