 # FoundryOS
 ## Cloning
 ```sh
 git clone https://git.zxq5.dev/OsDev/FoundryOS.git
 ```
 ## Build dependencies
 * latest rust nightly release
 * all necessary rust components installed
 * xorriso: creates ISO images to be booted from.
 * (Optional / Recommended) qemu: to run the kernel. (this may be packaged as qemu-desktop)
 * (Optional) GDB: for debugging the kernel.
 ```sh
 rustup update
 rustup override set nightly
 rustup component add rust-src
 rustup component add llvm-tools-preview
 ```
 ## Building & Running in qemu
 ```sh
 cargo run
 ```
 ## Running in GDB
 ```sh
 USE_GDB=1 cargo run
 ```
 ## Build errors
 If you see a qemu error like this:
 ```
 qemu-system-x86_64: -drive if=pflash,format=raw,readonly=on,file=<...>/OVMF_CODE.fd: Could not open '<...>/OVMF_CODE.fd': No such file or directory
 ```
 Simply delete the ./build directory and try to rebuild the program. Using the runner script or `cargo run` will download the required files for you, this is because the script only checks for the presence of one file and not the VARS file.
 Alternatively, you may disable using a UEFI firmware with qemu like so:
 ```sh
 USE_LEGACY_BIOS=1 cargo run
 ```
 ## Debugging
 See [debugging](docs/Debugging/DEBUGGING.md) for some help with this, including commands to help with disassembly.
 If you have any other issues, feel free to create an issue or a PR.

 # Debugging the Kernel
 Here we will add some helpful tips on debugging the kernel.
 ## Disassembling a public function
 To disassemble a public function, first we need a symbol in the public symbol table, so start by making the function fully public (including any parent modules). Do this as though you are trying to make a public function for a library crate (this includes the `kernel` crate). Simply mark the function and any parent modules as public, up until the point of [lib.rs (kernel link)](../../kernel/src/lib.rs).
 Then, we need to find the specific demangled symbol to disassemble, because the default objdump output can be very verbose.
 ```sh
 # Change as required, I pipe to less and /SEARCH FOR FUNCTION HERE.
 nm --demangle ./build/target/x86_64-kernel/debug/kernel | less
 # Now just paste the symbol where it says YOUR_SYMBOL_HERE and profit. Use -Mintel for Intel assembly syntax.
 objdump -Matt --source --line-numbers --visualize-jumps ./build/target/x86_64-kernel/debug/kernel --demangle=rust --disassemble="YOUR_SYMBOL_HERE"
 ```
