Subject: [PATCH v7 0/2] drivers/perf: hisi: Add support for PCIe PMU
Date: Thu, 24 Jun 2021 18:59:42 +0800 [thread overview]
Message-ID: <1624532384-43002-1-git-send-email-liuqi115@huawei.com> (raw)
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.
Changes since v6:
- Move the driver to drivers/perf/hisilicon.
- Treat content in PMU counter and ext_counter as different PMU events, and
export them separately.
- Address the comments from Will and Krzysztof.

Changes since v5:
- Fix some errors when build under ARCH=xtensa.
- Link: https://lore.kernel.org/linux-arm-kernel/1621946795-14046-1-git-send-email-liuqi115@huawei.com/
Changes since v4:
- Replace irq_set_affinity_hint() with irq_set_affinity().

Changes since v3:
- Fix some warnings when build under 32bits architecture.
- Address the comments from John.
