Subject: [PATCH 0/2] drivers/perf: hisi: Add support for PCIe PMU
Date: Wed, 7 Apr 2021 17:49:01 +0800 [thread overview]
Message-ID: <1617788943-52722-1-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.
