Subject: [PATCH v4 0/2] drivers/perf: hisi: Add support for PCIe PMU
Date: Wed, 19 May 2021 17:48:59 +0800 [thread overview]
Message-ID: <1621417741-5229-1-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.
This patchset is based on 5.13-rc1.
Changes since v3:
- Fix some warnings when build under 32bits architecture.
- Address the comments from John.
