 # FoundryOS

-## Cloning and building
+## Cloning
+```sh
+git clone https://git.zxq5.dev/OsDev/FoundryOS.git
+```

-Here are some simple steps to get started:
+## 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
-# If you have not yet cloned the repo:
-git clone --recurse-submodules https://git.zxq5.dev/OsDev/FoundryOS.git
-# If you already cloned the repo:
-git submodule update --init --recursive
+rustup update
+rustup override set nightly
+rustup component add rust-src
+rustup component add llvm-tools-preview
+```

-cargo build
-# This will build the binaries if required - no need to call cargo build.
+## Building & Running in qemu
+```sh
 cargo run
 ```

-### Build dependencies
+## Running in GDB
+```sh
+USE_GDB=1 cargo run
+```

-* jq: checks whether the app is to be run in debugging mode.
-* libisoburn: creates ISO images to be booted from.
-* qemu: to run the kernel.
+## 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"
+```

-# libk is for the code that did not make the kernel*
-
-\*crate, lol.
-
-libk is an attempt to move away from the godforsaken git submodules that plagued our forefathers. Now we have a crate containing a bunch of code that didn't quite make the core kernel crate, which should be:
-
-* simpler to maintain
-* has a catchier name
-* less fighting with Cargo.toml manifests
-
-## TODO:
-
-A lot of things must be improved and worked on, feel free to add extra TODOs below.
-
-[] Create a kernel logging abstraction similar to Linux. (this should probably just use the serial drivers)
-
-The rationale behind this is that we want some sort of debug log/tracing support so we aren't just printf debugging forever.
-
-## Authors
-
-Again, write your name below if you like:
-
-* @zxq5 (wrote most of the libraries as of 23/02/25)
-* @nullndvoid (made this lushious library crate)
