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 PMU Events Specification v1.1 URL: https://github.com/fujitsu/FUJITSU-MONAKA Changes in v5: - Update PMU events for FUJITSU-MONAKA to latest(v1.1) spec. The changed events are as follows: - Removed events: ea-memory-mac-read ea-memory-mac-pwrite - Description changed events: read-count-return read-count-return-pftgt-hit read-count-return-pftgt-miss ea-mac ea-memory ea-ha ea-pci - Modify the code as suggested. (Jonathan Cameron) - Added include mod_devicetable.h. - EA events that share the same description as MAC events have been removed. These events will remain in the specification, but will be removed from the code. These events will be supported in future enhancements as the specification changes. - Changed MAC events with the same description to different description. - Changed some programming styles as suggested. - Link to v4:https://lore.kernel.org/all/20250116045911.3382537-1-fj5100bi@xxxxxxxxxxx/ Koichi Okuno (2): perf: Fujitsu: Add the Uncore MAC PMU driver perf: Fujitsu: Add the Uncore PCI PMU driver .../admin-guide/perf/fujitsu_mac_pmu.rst | 73 +++ .../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 | 569 ++++++++++++++++++ drivers/perf/fujitsu_pci_pmu.c | 553 +++++++++++++++++ 7 files changed, 1267 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 -- 2.43.0
