| The aarch64_efi_defconfig allows to build a minimal Linux system that |
| can boot on all AArch64 servers providing an EFI firmware and ACPI. |
| |
| Building and booting |
| ==================== |
| |
| $ make aarch64_efi_defconfig |
| $ make |
| |
| The file output/images/disk.img is a complete disk image that can be |
| booted, it includes the grub2 bootloader, Linux kernel and root |
| filesystem. |
| |
| Testing under Qemu |
| ================== |
| |
| This image can also be tested using Qemu: |
| |
| qemu-system-aarch64 \ |
| -M virt \ |
| -cpu cortex-a57 \ |
| -m 512 \ |
| -nographic \ |
| -bios </path/to/QEMU_EFI.fd> \ |
| -drive file=output/images/disk.img,if=none,format=raw,id=hd0 \ |
| -device virtio-blk-device,drive=hd0 \ |
| -netdev user,id=eth0 \ |
| -device virtio-net-device,netdev=eth0 |
| |
| Note that </path/to/QEMU_EFI.fd> needs to point to a valid aarch64 UEFI |
| firmware image for qemu. |
| It may be provided by your distribution as a edk2-aarch64 or AAVMF |
| package, in path such as /usr/share/edk2/aarch64/QEMU_EFI.fd . |
