As of now it is\ncapable of:\n- Initializing the CPU from real-mode all the way to 64-bit mode.\n- Parse the E820 memory map from the BIOS.\n- Read the kernel ELF image from the boot disk (the ELF immediately follows the\n  bootloader's second stage on disk, i.e. no partitioning and no filesystem\n  support).\n- Parse the kernel ELF and load its segments to memory.\n- Jump to the 64-bit kernel entry point.\n\nThe C++ kernel is still **work in progress**. As of now the following are\nsupported:\n- Basic CPU initialization: segmentation, interrupts, paging\n- ACPI table parsing\n- IO-APIC(s)\n- LAPIC\n- Multicore support, including Inter-Processor-Interrupts\n- Processes and context switch, although the scheduler is not yet implemented.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjbouron%2Fx86_64-kernel","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjbouron%2Fx86_64-kernel","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjbouron%2Fx86_64-kernel/lists"}
