Subject: [PATCH v2 0/1] perf: Add --pmu-filter option for filtering PMUs
Date: Tue, 10 Mar 2026 12:06:06 +0800 [thread overview]
Message-ID: <20260310040607.1780971-1-xiaqinxin@huawei.com> (raw)
This patch adds a new --pmu-filter option to perf-stat command to allow
filtering events on specific PMUs. This is useful when there are
multiple PMUs with same type (e.g. hisi_sicl2_cpa0 and hisi_sicl0_cpa0).
