The socket is commonly used across all vhost-devices to +communicate with the vhost-user frontend device. + +The 'can-out' represents +the actual CAN/FD device appears in the host system which vhost-device-can will +forward the messages from the frontend side. Finaly, the 'can-in' is again a +CAN/FD device connected on the host systems and vhost-device-can reads CAN/FD +frames and sends them to the frontend. The 'can-in' and 'can-out' can be find +by "ip link show" command. Also, the vhost-device-can may have the same CAN/FD +device name for both 'can-in' and 'can-out', if the user desires to setup a +loopback configuration. + + +This program is tested with Virtio-loopback's `-device vhost-user-can`. +Examples section below. + +## Synopsis + +**vhost-device-can** [*OPTIONS*] + +## Options + +.. program:: vhost-device-gpio + +.. option:: -h, --help + + Print help. + +.. option:: -s, --socket-path=PATH + +.. option:: -i, --can-int='CAN/FD interface name' + + The name of the input CAN interface to retrive CAN frames by + +.. option:: -o, --can-out='CAN/FD interface name' + + The name of the ouput CAN interface to send the CAN frames + +## Examples + +The daemon should be started first: + +:: + + host# vhost-device-can --socket-path=can.sock --can-in="can0" --can-out="can1" + +The virtio-looback invocation needs to insert the [virtio-loopback-transport](https://git.virtualopensystems.com/virtio-loopback/loopback_driver/-/tree/epsilon-release) driver +and then start the [virito-loopback-adapter](https://git.virtualopensystems.com/virtio-loopback/adapter_app/-/tree/epsilon-release) which is the intermediate between +vhost-device and virtio-loopback-transport driver. + +:: + + host# sudo insmod loopback_driver.ko + host# sudo ./adapter -s /path/to/can.sock0 -d vhucan + +## License + +This project is licensed under either of + +- [Apache License](http://www.apache.org/licenses/LICENSE-2.0), Version 2.0 +- [BSD-3-Clause License](https://opensource.org/licenses/BSD-3-Clause) diff --git a/meta-egvirt/recipes-extended/vhost-device-can/vhost-device-can-0.1.0/src/backend.rs b/meta-egvirt/recipes-extended/vhost-device-can/vhost-device-can-0.1.0/src/backend.rs new file mode 100644 index 00000000..177c76cc --- /dev/null +++ b/meta-egvirt/recipes-extended/vhost-device-can/vhost-device-can-0.1.0/src/backend.rs @@ -0,0 +1,170 @@ +// VIRTIO CAN Emulation via vhost-user +// +// Copyright 2023 VIRTUAL OPEN SYSTEMS SAS.
