It is a PCIe Root Complex integrated End Point(RCiEP) device added on Hip09. Each PCIe Core has a PMU RCiEP to monitor multi root ports and all Endpoints downstream these root ports. HiSilicon PCIe PMU is supported to collect performance data of PCIe bus, such as: bandwidth, latency etc. Changes since v7: - Drop headerfile cpumask.h and cpuhotplug.h. - Rename events in perf list: bw->flux, lat->delay, as driver doesn't process bandwidth and average latency data. - Link: https://lore.kernel.org/linux-arm-kernel/1624532384-43002-1-git-send-email-liuqi115@huawei.com/ Changes since v6: - Move the driver to drivers/perf/hisilicon. - Treat content in PMU counter and ext_counter as different PMU events, and export them separately. - Address the comments from Will and Krzysztof. - Link: https://lore.kernel.org/linux-arm-kernel/1622467951-32114-1-git-send-email-liuqi115@huawei.com/ Changes since v5: - Fix some errors when build under ARCH=xtensa. - Link: https://lore.kernel.org/linux-arm-kernel/1621946795-14046-1-git-send-email-liuqi115@huawei.com/ Changes since v4: - Replace irq_set_affinity_hint() with irq_set_affinity(). - Link: https://lore.kernel.org/linux-arm-kernel/1621417741-5229-1-git-send-email-liuqi115@huawei.com/ Changes since v3: - Fix some warnings when build under 32bits architecture. - Address the comments from John. - Link: https://lore.kernel.org/linux-arm-kernel/1618490885-44612-1-git-send-email-liuqi115@huawei.com/ Changes since v2: - Address the comments from John. - Link: https://lore.kernel.org/linux-arm-kernel/1617959157-22956-1-git-send-email-liuqi115@huawei.com/ Changes since v1: - Drop the internal Reviewed-by tag. - Fix some build warnings when W=1. - Link: https://lore.kernel.org/linux-arm-kernel/1617788943-52722-1-git-send-email-liuqi115@huawei.com/ Qi Liu (2): docs: perf: Add description for HiSilicon PCIe PMU driver drivers/perf: hisi: Add driver for HiSilicon PCIe PMU Documentation/admin-guide/perf/hisi-pcie-pmu.rst | 104 +++ MAINTAINERS | 2 + drivers/perf/hisilicon/Kconfig | 9 + drivers/perf/hisilicon/Makefile | 2 + drivers/perf/hisilicon/hisi_pcie_pmu.c | 967 +++++++++++++++++++++++ include/linux/cpuhotplug.h | 1 + 6 files changed, 1085 insertions(+) create mode 100644 Documentation/admin-guide/perf/hisi-pcie-pmu.rst create mode 100644 drivers/perf/hisilicon/hisi_pcie_pmu.c -- 2.7.4 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
