The driver provides common "uncore" functions to avoid code duplication and support adding more device PMUs (like L2 cache) in the future. Patches are on top of 4.13-rc1. Changes to v6: - Make driver stand-alone again without hooking into EDAC - depend on ARCH_THUNDER Changes to v5: - Only allow built-in CONFIG_CAVIUM_PMU - Drop unneeded export of perf_event_update_userpage() - Simplify callbacks in edac code, move CONFIG_CAVIUM_PMU check to header file - Fix some sparse static warnings - Add documentation - Fix OCX TLK event_valid check - Add group validation in event_init - Add a guard variable to prevent calling init twice - Use kasprintf and fix pmu name allocation - Remove unneeded check for embedded pmu - Loop around local64_cmpxchg - Simplify cvm_pmu_lmc_event_valid - Fix list_add error case Jan Glauber (3): perf: cavium: Support memory controller PMU counters perf: cavium: Support transmit-link PMU counters perf: cavium: Add Documentation Documentation/perf/cavium-pmu.txt | 74 +++++ drivers/perf/Kconfig | 8 + drivers/perf/Makefile | 1 + drivers/perf/cavium_pmu.c | 632 ++++++++++++++++++++++++++++++++++++++ include/linux/cpuhotplug.h | 1 + 5 files changed, 716 insertions(+) create mode 100644 Documentation/perf/cavium-pmu.txt create mode 100644 drivers/perf/cavium_pmu.c -- 2.9.0.rc0.21.g7777322
