Date: Wed, 19 Jul 2017 14:08:44 +0200 From: Jan Glauber <jglauber@...ium.com> To: Mark Rutland <mark.rutland@....com> Cc: Will Deacon <will.deacon@....com>, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, Jan Glauber <jglauber@...ium.com> Subject: [PATCH v7 0/3] Cavium ARM64 uncore PMU support Add support for various PMU counters found on the Cavium ThunderX and OcteonTx SoC. 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
