Subject: [PATCH 2/2] perf script: Support dso filter
Date: Mon, 25 Jan 2021 07:27:50 +0800 [thread overview]
Message-ID: <20210124232750.19170-2-yao.jin@linux.intel.com> (raw)
In-Reply-To: <20210124232750.19170-1-yao.jin@linux.intel.com>
Other perf tool builtins have already supported dso filter.
For example,
perf report --dso, which only considers symbols in these dsos.
Now dso filter is supported for perf-script.
root@kbl-ppc:~# ./perf script --dso "[kernel.kallsyms]"
