The turbostat utility is useful on Linux systems for reporting idle/power-state statistics, temperatures, and other useful metrics for modern CPUs. It's also able to dive deeper and provide various MSR values and counters and other intriguing CPU bits. For much of these features root access is required and thus turbostat has bailed out up to this point if not running as root. But as a number of the metrics can still be obtained without root access, turbostat is finally being adapted to handle running better as a non-root user...

Intel's FFmpeg Cartwheel is where they maintain their various yet-to-be-upstreamed patches for the FFmpeg multimedia library either to enhance/enable new Intel graphics hardware support or improve/add extra functionality to this widely-used open-source library.
