Subject: [PATCH v2 perf,bpf 09/11] perf-top: add option --bpf-event
Date: Thu, 14 Feb 2019 16:00:10 -0800	[thread overview]
Message-ID: <20190215000010.2590505-8-songliubraving@fb.com> (raw)
In-Reply-To: <20190215000010.2590505-1-songliubraving@fb.com>

bpf events are only tracked when opts->bpf_event is enabled. This patch
adds command line flag to enable this for perf-top.
