Week7:

• This week: need to compare and update the flags used for runqemu to run jailhouse in qemux86-64
• Now this requires making changes and adding more tags to the basic script used by runqemu:-

• tmp/work/x86_64-linux/qemu-helper-native/1.0-r1/recipe-sysroot-native/usr/bin//qemu-system-x86_64 -device virtio-net-pci,netdev=net0,mac=52:54:00:12:34:02 \

   -netdev tap,id=net0,ifname=tap0,script=no,downscript=no -drive file=tmp/deploy/images/qemux86-64/agl-demo-platform-qemux86-64-20180206055341.rootfs.ext4,if=virtio,format=raw \

   -show-cursor -usb -usbdevice tablet -device virtio-rng-pci -vga virtio  -machine q35 -cpu kvm64 -cpu qemu64,+ssse3,+sse4.1,+sse4.2,+popcnt -enable-kvm -m 2048 \

   -serial mon:vc -serial mon:stdio -serial null -kernel tmp/deploy/images/qemux86-64/bzImage--4.10.17+git0+40ee48ac09_c1d8c4408b-r0-qemux86-64-20171214150211.bin \

   

   -append 'root=/dev/vda rw highres=off  console=ttyS0 mem=2048M ip=192.168.7.2::192.168.7.1:255.255.255.0 vga=0 uvesafb.mode_option=1024x768-32 oprofile.timer=1 uvesafb.task_timeout=-1 '

  
  
• The early realisation was-
  • to remove all the unwanted spaces & make it cleaner (works wonders)
  • go about checking the qemu manual and all the flags given (and qemu has alot of them.)
  • my qemu was at v2 and required am upgrade to v5
  • compare script with the script made by jailhouse for its isar build based images which can be found here: https://github.com/siemens/jailhouse-images/blob/master/start-qemu.sh

• Another part of this task is to modify the QB variables so that runqemu does the right thing, using the following links to get there :
  • https://git.yoctoproject.org/cgit.cgi/poky/plain/meta/classes/qemuboot.bbclass
  • https://git.yoctoproject.org/cgit.cgi/poky/plain/scripts/runqemu
• Upcoming gsoc evaluations in the following week
