New generic defconfig for aarch64, to run on aarch64 servers compliant with EFI firmware and ACPI. This can also be tested with qemu, and is useful so that we have an arm defconfig with grub enabled. Tested with qemu 2.11.2 and AAVMF, the aarch64 virtual machine UEFI firmware.

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 .
