[PATCH v6 0/2] perf: Fujitsu: Add Uncore MAC/PCI PMU driver

[Koichi Okuno]

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

Changes in v6:
- Modify the code as suggested. (Peter Zijlstra)
  - Added PERF_PMU_CAP_NO_INTERRUPT which means not being able to sample.
- Link to v5:https://lore.kernel.org/all/20250617102819.3685543-1-fj2767dz@fujitsu.com/
