I am using the following command to boot "xlnx-versal-virt" board with "canbus" and connect it to host machine using "canbus"
$ qemu-system-aarch64 -M xlnx-versal-virt -m 4G -serial mon:stdio -display none -kernel ~/linux_kernel/linux-5.15.157/arch/arm64/boot/Image \ -device virtio-rng-device,bus=virtio-mmio-bus.0 -drive if=none,index=0,file=rootfs.img,format=raw,id=hd0 \ -device virtio-blk-device,drive=hd0 -append root=/dev/vda -nic user \ -object can-bus,id=canbus0 -machine canbus0=canbus0 -object can-bus,id=canbus1 -machine canbus1=canbus1 \ -object can-host-socketcan,id=socketcan0,if=vcan0,canbus=canbus0 ->I am using the cansend and candump application to test it. ->After sending certain packets the buffer is getting full. I am seeing that while ":request_irq" from xilinc_can driver gets called it should invoke "xcan_interrupt" function. I have added prints in those functions. "xcan_interrupt" function is not getting called. ->If i check the interrupts on cpu for 'can' interface the count is 0. Thank You in Advance!!
