This series implements TPMI as Intel Speed Select Technology (Intel SST) HW interface. TPMI has several advantages for Intel SST. This replaces legacy mailbox and MMIO with architectural interface over TPMI. This improves performance for HPC type applications. One single IOCTL command replaces 10s of IOCTLs for mailboxes. This allowed to offer many more performance levels and SST configurations. Users use intel-speed-select utility to configure Intel SST. User of the tool still can use the same commands. The utility uses new IOCTLs based on the new API version. The TPMI documentation can be downloaded from: https://github.com/intel/tpmi_power_management This series depends on previously posted series: - platform/x86/intel: Add TPMI support Uses 6.2-rc1 as baseline, so the patchset needs to be rebased.
