Tue, 26 May 2026 18:42:23 +0200

can: virtio: Add virtio CAN driverAdd virtio CAN driver based on Virtio 1.4 specification (seehttps://github.com/oasis-tcs/virtio-spec/tree/virtio-1.4). The driverimplements a complete CAN bus interface over Virtio transport,supporting both CAN Classic and CAN-FD Ids. In term of frames, itsupports classic and CAN FD. RTR frames are only supported with classicCAN.Usage:- "ip link set up can0" - start controller- "ip link set down can0" - stop controller- "candump can0" - receive frames- "cansend can0 123#DEADBEEF" - send framesSigned-off-by: Harald Mommer Co-developed-by: Harald Mommer Signed-off-by: Mikhail Golubev-Ciuchea Co-developed-by: Marc Kleine-Budde Signed-off-by: Marc Kleine-Budde Cc: Damir Shaikhutdinov Reviewed-by: Francesco Valla Tested-by: Francesco Valla Signed-off-by: Matias Ezequiel Vara Larsen Signed-off-by: Michael S.
