Subject: [PATCH v2 0/2] drivers/perf: hisi: Add support for PCIe PMU
Date: Fri, 9 Apr 2021 17:05:55 +0800	[thread overview]
Message-ID: <1617959157-22956-1-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 v1:
- Drop the internal Reviewed-by tag.
- Fix some build warnings when W=1.
