Subject: [PATCH v4 3/4] perf report: Add SPE options to --itrace argument
Date:   Tue, 11 Feb 2020 14:04:44 +0000

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Tan Xiaojun <tanxiaojun@huawei.com>

The previous patch added support in "perf report" for some arm-spe
events(llc-miss, tlb-miss, branch-miss, remote_access). This patch
adds their help instructions.
