Subject: [PATCH] DSPBRIDGE: wait less and check the mailbox more.
Date: Wed,  4 Mar 2009 12:11:36 -0600	[thread overview]
Message-ID: <1236190296-21667-6-git-send-email-x0095840@ti.com> (raw)
In-Reply-To: <1236190296-21667-5-git-send-email-x0095840@ti.com>

Performance is increased if we wait less and check the mailbox more when it's
full.
