Subject: [PATCH RFC 02/10] crypto: sun8i-ce: increase task list size
Date: Tue, 14 Jan 2020 14:59:28 +0100 [thread overview]
Message-ID: <20200114135936.32422-3-clabbe.montjoie@gmail.com> (raw)
In-Reply-To: <20200114135936.32422-1-clabbe.montjoie@gmail.com>
The CE can handle more than 1 task at once, so this patch increase the size of
the task list up to 8.
For the moment I did not see more gain beyong this value.
