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. This patchset is based on 5.13-rc1. 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 | 6 + drivers/perf/Kconfig | 2 + drivers/perf/Makefile | 1 + drivers/perf/pci/Kconfig | 16 + drivers/perf/pci/Makefile | 2 + drivers/perf/pci/hisilicon/Makefile | 3 + drivers/perf/pci/hisilicon/hisi_pcie_pmu.c | 1016 ++++++++++++++++++++++ include/linux/cpuhotplug.h | 1 + 9 files changed, 1151 insertions(+) create mode 100644 Documentation/admin-guide/perf/hisi-pcie-pmu.rst create mode 100644 drivers/perf/pci/Kconfig create mode 100644 drivers/perf/pci/Makefile create mode 100644 drivers/perf/pci/hisilicon/Makefile create mode 100644 drivers/perf/pci/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
