290 "speed-select-turbo-freq" (Intel(R) SST-TF) is supported at both performance
293 The Intel(R) SST-BF and the Intel(R) SST-TF features are built on a foundation
294 technology called Intel(R) Speed Select Technology - Core Power (Intel(R) SST-CP).

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