Gunnar Beutner	3678f78bfb	Prekernel: Make sure the last few bytes of the kernel image are mapped ... Depending on the exact layout of the .ksyms section the kernel would fail to boot because the kernel_load_end variable didn't account for the section's size.	2021-07-19 17:47:54 +02:00
Gunnar Beutner	b6ddb4b70f	Kernel: Simplify the linker script for the prekernel	2021-07-19 11:29:09 +02:00
Gunnar Beutner	7e94b090fe	Kernel: Introduce basic pre-kernel environment ... This implements a simple bootloader that is capable of loading ELF64 kernel images. It does this by using QEMU/GRUB to load the kernel image from disk and pass it to our bootloader as a Multiboot module. The bootloader then parses the ELF image and sets it up appropriately. The kernel's entry point is a C++ function with architecture-native code. Co-authored-by: Liav A <liavalb@gmail.com>	2021-07-18 17:31:13 +02:00
