100 1.1 PCC interface
117 The PCC driver (pcc-cpufreq) allows OSPM to take advantage of the PCC
126 1.1 PCC interface:
128 The complete PCC specification is available here:
141 The following commands are supported by the PCC interface:
161 the system. Therefore, PCC is capable of performing "group" updates. With PCC
182 The PCC driver will load on any system where the platform firmware:
188 platforms PCC is the "default" choice.
192 is not implemented, the PCC driver will fail to load silently.

554 depends on PCC
557 The PCC Address Space also referred as PCC Operation Region pertains
558 to the region of PCC subspace that succeeds the PCC signature.
560 The PCC Operation Region works in conjunction with the PCC Table
561 (Platform Communications Channel Table). PCC subspaces that are
562 marked for use as PCC Operation Regions must not be used as PCC
564 MPST. These standard features must always use the PCC Table instead.
