WebJun 15, 2015 · Changes since V3: - Split CPPC backend methods into separate files. - Add frontend driver which plugs into existing CPUfreq governors. - Simplify PCC driver by moving communication space mapping and read/write into client drivers. Changes since V2: - Select driver if !X86, since intel_pstate will use HWP extensions instead. WebRe-parenting to intermediate clock is supported now by the clock driver and thus there is no need in a customized CPUFreq driver, all that code
