We now pass along the toolchain type to all subcommands. This ensures
that gdb will load the correct debug information for kernels compiled
with Clang, and the following warning won't appear with the GNU
toolchain:
> WARNING: unknown toolchain 'gdb'. Defaulting to GNU.
> Valid values are 'Clang', 'GNU' (default)

This appears to have regressed recently in commit 783a58dbc.

Previously debug-kernel.sh wouldn't detect source if you launched the
script from the wrong path. By explicitly setting the name, source will
be loaded by gdb in all situations.

The function arguments almost always optimized away, so you never get
much value out of showing these in the default back trace view, it just
adds a bunch of extra stuff that you need to visual wade through.
So lets disable showing them.

This enables further work on implementing KASLR by adding relocation
support to the pre-kernel and updating the kernel to be less dependent
on specific virtual memory layouts.

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.

This adds a TUI window that displays disassembly/source code which
I've found quite useful.

Multiboot only supports ELF32 executables. This changes the build
process to build an ELF32 executable which has a 32-bit entry point,
but consists of mostly 64-bit code.

This script automatically manages the toolchain and cmake/ninja folders
making it easier to manage the different target architectures.
|
|
This appears to have been broken since the migration to cmake.
