Subject: [dpdk-dev] [PATCH v4 5/5] lib/distributor: use wait event scheme
Date: Wed, 20 Oct 2021 16:45:23 +0800
Message-ID: <20211020084523.1309177-6-feifei.wang2@arm.com> (raw)
In-Reply-To: <20211020084523.1309177-1-feifei.wang2@arm.com>

Instead of polling for bufptr64 to be updated, use
wait event for this case.
