Dear Nikita and other, my student Matyas Bobek has chosen to work on QEMU CAN support in a frame of his study final project.
We have identified iMX6 FlexCAN as the next interesting CAN controller for emulation. One of our industrial partners is using iMX6 based system with CAN and iMX6 SabreLite is supported by QEMU. iMX6 is often used in industry still and FlexCAN has use even for iMX8 emulation if it is added into QEMU in the future. In the preparatory work, we want to setup shared directory between host and guest kernel using 9P FS on PCI virtio. The development environment is based on current mainline QEMU and mainline Linux kernel sources. We use standard QEMU options -virtfs local,path=shareddir,security_model=none,mount_tag=shareddir and the 1af4:1009 is seen by monitor command "info pci" but on the guest kernel side only "16c3:abcd" DWC_usb3 / PCIe bridge is seen but none from the mapped devices, virtio (1af4:1009), CTU CAN FD, Kvaser CAN. The imx6q-sabrelite DTS is used with standard device-tree https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/nxp/imx/imx6q-sabrelite.dts We hope that all required drivers are enabled in the kernel. But it is possible that something has been overlooked. Do you have some hint or some kernel and QEMU working example for iMX6 PCIe device mapping? Thanks in advance.
