Hi, Thanks for providing relevant information. FYI I am using Qemu version *4.2.94 (v5.0.0-rc4-dirty).* I am using *virt* board.
Where we need to set *user creatable *to true? Any other modification is needed to allow sysbus device support? Below is the script which I am using to boot linux image with pl061 device on virt board. #!/bin/bash > > KERNEL="/lhome/priyamvad/debian_qemu_arm32/vmlinuz-3.16.0-6-armmp-lpae" > > INIT_IMAGE="/lhome/priyamvad/debian_qemu_arm32/initrd.img-3.16.0-6-armmp-lpae" > DISK="/lhome/priyamvad/debian_qemu_arm32/hda30.qcow2" > > ./qemu-system-arm \ > -M virt \ > -m 1024 \ > -smp 4 \ > -kernel $KERNEL \ > -object rng-random,filename=/dev/urandom,id=rng0 \ > -device virtio-rng-device,rng=rng0 \ > -initrd $INIT_IMAGE \ > -append 'root=/dev/vda2' \ > -drive if=none,file=$DISK,format=qcow2,id=hd \ > -device pl061 \ > -device virtio-blk-device,drive=hd \ > -device virtio-net-device,netdev=usernet \ > -netdev user,id=usernet,hostfwd=tcp::2222-:22 \ > -nographic > Is the above script correct to boot linux image with pl061 device on virt board?
