Hello, I'm programming CoreFreq to monitor Core's performance counters, based on a Linux Kernel module. CoreFreq can be easily built from source code at http://github.com/cyring/CoreFreq

Hello, To test my algorithm with processors I don't have, is there a way to fake cpuid & msr returned bits in a virtualized environment ? For instance: in a VirtualBox guest it still reads the brand signature id from the host cpuid.

Intel SDE is a nice software

Intel SDE is a nice software to emulate processors. In userspace, my XFreq daemon reports the faked cpuid, thus processor brand signature. msr registers appear to remain the host ones.
