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. This series depends on previously posted series: - platform/x86/intel: Intel TPMI enumeration driver Change History v2 - Rebased on top of review-hans branch of platform-drivers-x86 - Removed patches which are already present in this branch from the last review So number of patches are reduced from 12 to 8. - Rework patch for MSR 0x54 support - Use suggestion from Hans for suspend/resume callbacks - Add Reviewed-by and Test-by tags Srinivas Pandruvada (8): platform/x86: ISST: Add support for MSR 0x54 platform/x86: ISST: Enumerate TPMI SST and create framework platform/x86: ISST: Parse SST MMIO and update instance platform/x86: ISST: Add SST-CP support via TPMI platform/x86: ISST: Add SST-PP support via TPMI platform/x86: ISST: Add SST-BF support via TPMI platform/x86: ISST: Add SST-TF support via TPMI platform/x86: ISST: Add suspend/resume callbacks .../x86/intel/speed_select_if/Kconfig | 4 + .../x86/intel/speed_select_if/Makefile | 2 + .../intel/speed_select_if/isst_if_common.c | 28 + .../x86/intel/speed_select_if/isst_tpmi.c | 72 + .../intel/speed_select_if/isst_tpmi_core.c | 1438 +++++++++++++++++ .../intel/speed_select_if/isst_tpmi_core.h | 18 + include/uapi/linux/isst_if.h | 303 ++++ 7 files changed, 1865 insertions(+) create mode 100644 drivers/platform/x86/intel/speed_select_if/isst_tpmi.c create mode 100644 drivers/platform/x86/intel/speed_select_if/isst_tpmi_core.c create mode 100644 drivers/platform/x86/intel/speed_select_if/isst_tpmi_core.h -- 2.34.1
