Add support for various PMU counters found on the Cavium ThunderX and OcteonTx SoC. The PMU driver provides common "uncore" functions to avoid code duplication and support adding more device PMUs (like L2 cache) in the future. Changes to v9: - Fix build error in first EDAC patch - Use alphabetic ordering in some places - Store pmu name in struct pmu - Use devm_* - Remove mapping of LMC events, expose hardware event numbers directly - Simplify event removal Changes to v8: - Wrapper for PCI devices Jan Glauber (7): edac: thunderx: Remove suspend/resume support perf: export perf_event_update_userpage() edac,soc: thunderx: Add wrapper for EDAC LMC PCI device edac,soc: thunderx: Add wrapper for EDAC OCX PCI device perf: cavium: Support memory controller PMU counters perf: cavium: Support transmit-link PMU counters perf: cavium: Add Documentation Documentation/perf/cavium-pmu.txt | 75 +++++ drivers/edac/Kconfig | 3 + drivers/edac/thunderx_edac.c | 92 +----- drivers/perf/Kconfig | 15 + drivers/perf/Makefile | 1 + drivers/perf/cavium_pmu.c | 660 ++++++++++++++++++++++++++++++++++++++ drivers/soc/Kconfig | 1 + drivers/soc/Makefile | 1 + drivers/soc/cavium/Kconfig | 14 + drivers/soc/cavium/Makefile | 2 + drivers/soc/cavium/cavium_lmc.c | 53 +++ drivers/soc/cavium/cavium_ocx.c | 49 +++ include/linux/cpuhotplug.h | 1 + include/linux/soc/cavium/lmc.h | 12 + include/linux/soc/cavium/ocx.h | 12 + kernel/events/core.c | 1 + 16 files changed, 913 insertions(+), 79 deletions(-) create mode 100644 Documentation/perf/cavium-pmu.txt create mode 100644 drivers/perf/cavium_pmu.c create mode 100644 drivers/soc/cavium/Kconfig create mode 100644 drivers/soc/cavium/Makefile create mode 100644 drivers/soc/cavium/cavium_lmc.c create mode 100644 drivers/soc/cavium/cavium_ocx.c create mode 100644 include/linux/soc/cavium/lmc.h create mode 100644 include/linux/soc/cavium/ocx.h -- 2.9.0.rc0.21.g7777322
