[agl-dev-community] Parth Dode : GSOC Week 9 Update #gsoc

["Parth Dode" <dodecoder@xxxxxxxxx>]

Week9:

• This week: Create a conf file with the qemu boot variables and their values required for jailhouse to run 
• Thing is when you  start qemu and try to run " jailhouse hardware check" , the check must be passed for jailhouse to actually run. 
• Now this is the updated script that I used to run qemu:-

qemu-system-x86_64 \

-m 1024 \

-drive file=./tmp/deploy/images/qemux86-64/agl-image-minimal-qemux86-64.ext4,discard=unmap,if=none,id=disk,format=raw \

-serial vc -serial mon:stdio -netdev user,id=net \

-kernel ./tmp/deploy/images/qemux86-64/bzImage \

-append "root=/dev/sda intel_iommu=off memmap=82M\$0x3a000000 mem=1G vga=0x305 console=ttyS0,115200n8" \

-cpu host,-kvm-pv-eoi,-kvm-pv-ipi,-kvm-asyncpf,-kvm-steal-time,-kvmclock,-invpcid,-hypervisor \

-smp 4 \

-enable-kvm \

-machine q35,kernel_irqchip=split \

-device ide-hd,drive=disk \

-device intel-iommu,intremap=on,x-buggy-eim=on \

-device intel-hda,addr=1b.0 \

-device hda-duplex \

-device e1000e,addr=2.0,netdev=net \

 

• The above script does seem to pass the checks

• We then add a new conf file in our meta-agl-jailhouse , sorting out the updated script wrt the QB variables and then build the recipe so that when we use runqemu , the required script runs by default
• The following variables need to be filled for runqemu -

QB_SYSTEM_NAME:

QB_OPT_APPEND:

QB_DEFAULT_KERNEL:

QB_DEFAULT_FSTYPE:

QB_MEM:  

QB_MACHINE:

QB_CPU:

QB_CPU_KVM:

QB_KERNEL_CMDLINE_APPEND: "root=/dev/sda intel_iommu=off memmap=82M\$0x3a000000 mem=1G vga=0x305 console=ttyS0,115200n8"

 QB_DTB:

QB_AUDIO_DRV:

QB_AUDIO_OPT:

QB_KERNEL_ROOT:

QB_NETWORK_DEVICE:

QB_TAP_OPT:

QB_SLIRP_OPT:

QB_CMDLINE_IP_SLIRP:

QB_CMDLINE_IP_TAP:

QB_ROOTFS_OPT:

QB_SERIAL_OPT:

QB_TCPSERIAL_OPT:

QB_ROOTFS_EXTRA_OPT:

• Ended up setting up fresh new can boards with respective rpi's and connecting them.
