Subject: [dpdk-dev] [PATCH 6/7] vhost: get callfd before device setup
Date: Fri, 2 Feb 2018 18:28:56 -0500 [thread overview]
Message-ID: <1517614137-62926-7-git-send-email-zhihong.wang@intel.com> (raw)
In-Reply-To: <1517614137-62926-1-git-send-email-zhihong.wang@intel.com>
From: Xiao Wang <xiao.w.wang@intel.com>
This patch is to make sure device is configured with all needed guest
info. According to QEMU vhost message sequence, the real callfd comes
just before SET_VRING_ENABLE.
