315 The Intel(R) SST-BF and the Intel(R) SST-TF features are built on a foundation
316 technology called Intel(R) Speed Select Technology - Core Power (Intel(R) SST-CP).

530 Some features like Intel(R) SST-TF can only be enabled when CLOS based prioritization
531 is enabled. For this reason, disabling while Intel(R) SST-TF is enabled can cause
532 Intel(R) SST-TF to fail. This will cause the "disable" command to display an error
533 if Intel(R) SST-TF is already enabled. In turn, to disable, the Intel(R) SST-TF

547 Performance Profile (Intel(R) SST-PP) performance level configuration. It is
548 possible that only certain performance levels support Intel(R) SST-BF. It is also
