Subject: [dpdk-dev] [PATCH v6 4/7] virtio-user: add vhost adapter layer
Date: Thu, 2 Jun 2016 09:54:34 +0000 [thread overview]
Message-ID: <1464861277-130265-5-git-send-email-jianfeng.tan@intel.com> (raw)
In-Reply-To: <1464861277-130265-1-git-send-email-jianfeng.tan@intel.com>
This patch is to provide vhost adapter layer implementations. Instead
of relying on a hypervisor to translate between device emulation and
vhost backend, here we directly talk with vhost backend through the
vhost file. Depending on the type of vhost file,
- vhost-user is used if the given path points to a unix socket;
- vhost-kernel is used if the given path points to a char device.
Here three main APIs are provided to upper layer (device emulation):
- vhost_user_setup(), to set up env to talk to a vhost user backend;
- vhost_kernel_setup(), to set up env to talk to a vhost kernel backend.
- vhost_call(), to provide a unified interface to communicate with
vhost backend.
