Skylake processor supports a new set of RAPL registers for controlling entire SoC instead of just CPU package called PSys. This change adds support in two sub systems:
x86/perf: Adds basic support for Skylake RAPL and PSys support powercap/rapl: A new platform domain to the current power capping Intel RAPL driver. v4 Perf: - Rebased the patch as msr-index file changed. - Added a new Skylake H/L model - Changed RAPL_IDX_SKL to RAPL_IDX_SKL_CLN to avoid clash with SKL server domain once we add SKL server support Powercap/rapl: - Fix kbuild test robot compliant about invalid domain error in dmesg v3: As suggested by tglx adding support first in perf-rapl. Perf RAPL was missing RAPL support for Skylake Added support including Psys v2: Moved PSYS MSR defines to intel_rapl.c as suggested by Boris Srinivas Pandruvada (2): perf/x86/intel/rapl: support Skylake RAPL domains powercap: intel_rapl: PSys support arch/x86/events/intel/rapl.c | 51 +++++++++++++++++++++++++++-- arch/x86/include/asm/msr-index.h | 2 ++ drivers/powercap/intel_rapl.c | 69 ++++++++++++++++++++++++++++++++++++++++ 3 files changed, 120 insertions(+), 2 deletions(-) -- 1.9.1
