Subject: [virtio-dev] [PATCH v2] virtio-tee: Reserve device ID 46 for TEE device
Date: Mon, 25 Sep 2023 16:47:09 +0530 [thread overview]
Message-ID: <80a2e4337affb043909c348395fb45aeeb693dc7.1695640593.git.JESHWANTHKUMAR.NK@amd.com> (raw)
In a virtual environment, an application running in guest VM may want
to delegate security sensitive tasks to a Trusted Application (TA)
running within a Trusted Execution Environment (TEE). A TEE is a trusted
OS running in some secure environment, for example, TrustZone on ARM
CPUs, or a separate secure co-processor etc.
A virtual TEE device emulates a TEE within a guest VM. Such a virtual
TEE device supports multiple operations such as:
VIRTIO_TEE_CMD_OPEN_DEVICE – Open a communication channel with virtio
TEE device.
VIRTIO_TEE_CMD_CLOSE_DEVICE – Close communication channel with virtio
TEE device.
VIRTIO_TEE_CMD_GET_VERSION – Get version of virtio TEE.
VIRTIO_TEE_CMD_OPEN_SESSION – Open a session to communicate with
trusted application running in TEE.
VIRTIO_TEE_CMD_CLOSE_SESSION – Close a session to end communication
with trusted application running in TEE.
VIRTIO_TEE_CMD_INVOKE_FUNC – Invoke a command or function in trusted
application running in TEE.
VIRTIO_TEE_CMD_CANCEL_REQ – Cancel an ongoing command within TEE.
We would like to reserve device ID 46 for Virtio-TEE device.
