Subject: [PATCH v5 3/4] perf report: Add SPE options to --itrace argument
Date: Tue, 25 Feb 2020 11:57:38 +0000 [thread overview]
Message-ID: <20200225115739.18740-4-james.clark@arm.com> (raw)
In-Reply-To: <20200225115739.18740-1-james.clark@arm.com>
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.
