Subject: [PATCH 03/13] HW-latency: Use get_random_bytes_arch
Date: Sun, 4 Nov 2012 20:59:34 -0500 [thread overview]
Message-ID: <1352080784-30839-4-git-send-email-luming.yu@gmail.com> (raw)
In-Reply-To: <1352080784-30839-1-git-send-email-luming.yu@gmail.com>
To test rdrand on CPU like Ivy Bridget, we need feature aware random function.
