This adds two new dynamic PMUs to the Perf Events framework to program and control the Uncore MAC/PCI PMUs in Fujitsu chips. These drivers were created with reference to drivers/perf/qcom_l3_pmu.c. These drivers export formatting and event information to sysfs so they can be used by the perf user space tools with the syntaxes: perf stat -e mac_iod0_mac0_ch0/ea-mac/ ls perf stat -e mac_iod0_mac0_ch0/event=0x80/ ls perf stat -e pci_iod0_pci0/ea-pci/ ls perf stat -e pci_iod0_pci0/event=0x80/ ls FUJITSU-MONAKA Specification URL: https://github.com/fujitsu/FUJITSU-MONAKA Changes in v2: - Remove changes to arch/arm64/configs/defconfig (will post patch separately) (Krzysztof Kozlowski) - Add document file name to Documentation/admin-guide/perf/index.rst (Jonathan Cameron) - Modify files according to the suggestions (Jonathan Cameron) - Link to v1: https://lore.kernel.org/all/20241108054006.2550856-1-fj5100bi@xxxxxxxxxxx/ Yoshihiro Furudera (2): perf: Fujitsu: Add the Uncore MAC PMU driver perf: Fujitsu: Add the Uncore PCI PMU driver .../admin-guide/perf/fujitsu_mac_pmu.rst | 75 +++ .../admin-guide/perf/fujitsu_pci_pmu.rst | 50 ++ Documentation/admin-guide/perf/index.rst | 2 + drivers/perf/Kconfig | 18 + drivers/perf/Makefile | 2 + drivers/perf/fujitsu_mac_pmu.c | 570 ++++++++++++++++++ drivers/perf/fujitsu_pci_pmu.c | 550 +++++++++++++++++ include/linux/cpuhotplug.h | 2 + 8 files changed, 1269 insertions(+) create mode 100644 Documentation/admin-guide/perf/fujitsu_mac_pmu.rst create mode 100644 Documentation/admin-guide/perf/fujitsu_pci_pmu.rst create mode 100644 drivers/perf/fujitsu_mac_pmu.c create mode 100644 drivers/perf/fujitsu_pci_pmu.c -- 2.34.1
