Subject: [PATCH 18/22] perf record: Support custom vmlinux path
Date: Wed, 23 Sep 2015 11:22:39 +0000 [thread overview]
Message-ID: <1443007363-124182-19-git-send-email-wangnan0@huawei.com> (raw)
In-Reply-To: <1443007363-124182-1-git-send-email-wangnan0@huawei.com>
From: He Kuang <hekuang@huawei.com>
Make perf-record command support --vmlinux option if BPF_PROLOGUE is on.
'perf record' needs vmlinux as the source of DWARF info to generate
prologue for BPF programs, so path of vmlinux should be specified.
Short name 'k' has been taken by 'clockid'. This patch skips the short
option name and use '--vmlinux' for vmlinux path.
