Benim sorunum, cihaz ağacımdaki ağ aygıtlarının çok kararlı olmaması, bu nedenle qemu ile ana bilgisayar sistemi arasında bir klasörü paylaşmanın en iyi yolunun her iki tarafta önbellek olmadan aynı img'yi bağladığını düşündüm, ancak qemu'daki -hda seçeneği yapmıyor / dev / içinde mevcut olan hd.
İşte çalıştırdığım komut.
./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
Yani soru şudur: ağ oluşturmayı önlemenin ve qemu ile ana bilgisayar arasında paylaşılan bir dizininin olması için bir yol var mı?
EDIT: ile derledim
./configure --target-list="arm-softmmu,microblazeel-softmmu" --enable-fdt --disable-kvm --enable-virtfs
bu da gereken her şeyi mümkün kılmalıdır. Ancak koştuğumda
./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
veya
./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
alırım
No 'PCI' bus found for device 'virtio-9p-pci'
Belki de arm-softmmu/config-devices.mak
orada, CONFIG_PCI=y
pci'nin nesne dosyalarının yeterince olduğundan emin olmalıyım hw/pci
.
EDIT2: Aygıt ağacına qemu tarafından atıldığı gibi bakıldığında, taklit sistemde bir PCI veri yolu yoktur.
