Subject: [PATCH 05/24] perf report/top TUI: Support hotkey 'a' for annotation of unresolved addresses
Date: Wed, 25 Mar 2020 09:41:05 -0300	[thread overview]
Message-ID: <20200325124124.32648-6-acme@kernel.org> (raw)
In-Reply-To: <20200325124124.32648-1-acme@kernel.org>

From: Jin Yao <yao.jin@linux.intel.com>

In previous patch, we have supported the annotation functionality even
without symbols.

For this patch, it supports the hotkey 'a' on address in report view.
Note that, for branch mode, we only support the annotation for "branch
to" address.
