New features: - support of kernel tasks in 64bit mode - support of LwIP in 64bit mode Missing features in 64bit mode - user-level support - APIC support => SMP support To create a 64bit version of the MetalSVM kernel, the compiler flags “-m64 -mno-red-zone” and the assembler flags “-felf64” has to be used. Please use qemu-system-x86_64 as test platform. Notice, metalsvm.elf is a 32bit ELF file. However, it contains (beside the startup code) only 64bit code. This is required because GRUB doesn’t boot 64bit ELF kernels. Therefore, for disassembling via objdump the flag “-M x86-64” has to be used.
