add alpha version of x64 support
...
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.
