QEMU startup options '-device kvaser_pci,canbus=canbus0,host=vcan0' CAN bus Kvaser PCI CAN-S (single SJA1000 channel mapped into IO space) board.QEMU startup options '-device pci_can,chardev=canbus0,model=SJA1000' simple PCI memory space mapped SJA1000 which maps the chip registers directly into the first BAR of emulated device.When QEMU with CAN PCI support is compiled then next two CAN boards can be selected The sources of QEMU with CAN PCI board and SocketCAN interfacing can be found in branch " can-pci" More details can be found in article presented on RTLWS 2015 ( PDF), ( Slides). To SocketCAN (Linux kernel standard CAN API/drivers) on QEMU host side to connect emulated controllerĬAN bus to the virtual CAN network, host side monitoring tools or to the real CAN bus wired network. Use more these cards in our projects and can compare emulated HW behavior with real hardware. As for theĬoncrete card, we have selected Kvaser PCI because we (mentors from We decided to focus on SJA1000 chip, because it is widespread standalone controller variant. Such device can be easily connected to systems with different CPU architectures (x86, PowerPC, ARM, etc.). The PCI addon card hardware has been selected as the first CAN interface to be implement because In fact donated to work on CAN hardware emulation implementation for QEMU project.
#QEMU SYSTEM X86 64 PCI DRIVERS#
On preparation of complete emulated environment for CAN drivers testing and RTEMS GSoC slot has been Of common environment for code and RTEMS testing lead to the GSoC goal change. The intention to provide generic CAN subsystem for RTEMS was initial idea for Jin Yang GSoC 2013 project.
