 Despite being an OS-oriented tool, PMCTrack still allows gathering PMC values from user space, enabling kernel developers to carry out the necessary offline analysis and debugging to assist them during the scheduler design process. In addition, the tool provides both the scheduler and the userspace PMCTrack components with other insightful metrics available in modern processors that are not directly exposed as PMCs, such as cache occupancy or energy consumption.

 ## System requirements
 
 To support PMCTrack, a patched Linux kernel must be installed on the machine. A number of kernel patches for various Linux versions can be found in the `src/kernel-patches` directory. The name of each patch file encodes the Linux kernel version where the patch must be applied to as well as the processor architecture supported. The format is as follows:
