내 문제는 내 장치 트리의 네트워킹 장치가 안정적이지 않기 때문에 qemu와 호스트 시스템간에 폴더를 공유하는 가장 좋은 방법은 양쪽에 캐시없이 동일한 img를 마운트한다고 생각했지만 qemu의 -hda 옵션은 만들 수 없다는 것입니다 / dev /에서 사용 가능한 hd
다음은 내가 실행하는 명령입니다.
./qemu-xilinx/arm-softmmu/qemu-system-arm -M xilinx-zynq-a9 -m 1024 -serial null -serial mon:stdio -dtb resources/devicetree.dtb -kernel resources/zImage -initrd resources.qemu/ramdisk.img -nographic -s
질문은 : 네트워킹을 피하면서 qemu와 호스트 사이에 공유 디렉토리를 가지고있는 방법이 있습니까?
편집 : 나는 함께 컴파일
./configure --target-list="arm-softmmu,microblazeel-softmmu" --enable-fdt --disable-kvm --enable-virtfs
필요한 것을 활성화해야합니다. 그러나 내가 달릴 때
./qemu-xilinx/arm-softmmu/qemu-system-arm -M xilinx-zynq-a9 -m 1024 -serial null -serial mon:stdio -dtb /homes/cperivol/Sandbox/xilinx-zynq-bootstrap/resources/devicetree.dtb -kernel /homes/cperivol/Sandbox/xilinx-zynq-bootstrap/resources/zImage -initrd /homes/cperivol/Sandbox/xilinx-zynq-bootstrap/resources.qemu/ramdisk.img -nographic -s -fsdev local,path=/homes/cperivol/Sandbox/xilinx-zynq-bootstrap/qemu-sandbox/,security_model=passthrough,id=host0 -device virtio-9p-pci,fsdev=host0,mount_tag=host_tag0
또는
./qemu-xilinx/arm-softmmu/qemu-system-arm -M xilinx-zynq-a9 -m 1024 -serial null -serial mon:stdio -dtb resources/devicetree.dtb -kernel resources/zImage -initrd resources.qemu/ramdisk.img -nographic -s -virtfs local,path=/homes/cperivol/Sandbox/xilinx-zynq-bootstrap/qemu-sandbox/,mount_tag=host0,security_model=passthrough,id=host0
나는 얻다
No 'PCI' bus found for device 'virtio-9p-pci'
어쩌면 나는 arm-softmmu/config-devices.mak
거기 CONFIG_PCI=y
에 있고 pci의 객체 파일이 충분히 있음을 언급 해야 할 것입니다 hw/pci
.
EDIT2 : qemu에 의해 덤프 된 장치 트리를보고 에뮬레이트 된 시스템에는 PCI 버스가 포함되어 있지 않습니다.
