This patchset adds support for HiSilicon PCIe Performance Monitoring
Unit(PMU). 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-rc3.
Changes since v5:
- Fix some errors when build under ARCH=xtensa.
- Link: https://lore.kernel.org/linux-arm-kernel/[email protected]/
Changes since v4:
- Replace irq_set_affinity_hint() with irq_set_affinity().
- Link: https://lore.kernel.org/linux-arm-kernel/[email protected]/
Changes since v3:
- Fix some warnings when build under 32bits architecture.
- Address the comments from John.
- Link: https://lore.kernel.org/linux-arm-kernel/[email protected]/
Changes since v2:
- Address the comments from John.
- Link: https://lore.kernel.org/linux-arm-kernel/[email protected]/
Changes since v1:
- Drop the internal Reviewed-by tag.
- Fix some build warnings when W=1.
- Link: https://lore.kernel.org/linux-arm-kernel/[email protected]/
