![INTEL](/assets/categories/intel.webp)
Speed Select Core-Power (SST-CP) has been one of the features of Intel SST to begin with for allowing users to define per-core priorities when encountering power constraints. Intel SST to date has supported the performance profile and base/turbo frequency knobs while this SST-CP support is on the way and currently available in patch form.
There are 5 patches adding the Intel SST-CP support with new mailbox commands necessary kernel-side while the other work is to the intel-speed-select user-space tool. Intel-speed-select is the user-space tool for manipulating the SST behavior and is developed in-tree with the Linux kernel, similar to turbostat and other select utilities.
