Subject: [dpdk-dev] [PATCH v1 2/4] vhost: skip access lock when vDPA is configured
Date: Thu, 18 Jun 2020 16:28:04 +0000 [thread overview]
Message-ID: <1592497686-433697-3-git-send-email-matan@mellanox.com> (raw)
In-Reply-To: <1592497686-433697-1-git-send-email-matan@mellanox.com>
No need to take access lock in the vhost-user massage handler when
vDPA driver controls all the data-path of the vhost device.
It allows the vDPA set_vring_state operation callback to configure
guest notifications.
