+*Concepts you may want to Google beforehand: monolithic kernel, microkernel*
|
|
|
+**Goal: Pause and organize our code a little bit**
|
|
|
+
|
|
|
+Maybe you didn't realize it, but you already have your own kernel
|
|
|
+running!
|
|
|
+
|
|
|
+However, it does very little, just print an 'X'. Now is the time to stop for
|
|
|
+a moment and organize the code into folders, create a scalable Makefile for future code,
|
|
|
+and think on a strategy.
|
|
|
+
|
|
|
+Take a look at the new folder structure. Most of the files have been symlinked
|
|
|
+from previous lessons, so if we have to change them at some point, it will be
|
|
|
+a better idea to remove the symlink and create a new file.

+Strategy
|
|
|
+--------
|
|
|
+
|
|
|
+We will want to do many things with our OS:
|
|
|
+
|
|
|
+- Handle screen output and keyboard input, for starters
|
|
|
+- A tiny, basic `libc`
|
|
|
+- Memory management
|
|
|
+- Interrupt handling
|
|
|
+- Write a filesystem to store files
|
|
|
+- Create a very simple shell
|
|
|
+- Maybe we will write a simple text editor
|
|
|
+- Multiple processes and scheduling
|
|
|
+
|
|
|
+Probably we will go through them in that order, however it's soon to tell.
|
|
|
+
|
|
|
+If we feel brave enough:
|
|
|
+
|
|
|
+- A BASIC interpreter, like in the 70s!
|
|
|
+- A GUI
|
|
|
+- Networking
|
|
|
+
|
|
|
+
|
|
|
+You may notice that, since this is a tutorial, we haven't yet discussed which kind
|
|
|
+of kernel we will write. It will probably be a monolithic one since they are easier
|
|
|
+to design and implement, and after all this is our first OS. Maybe in the future
|
|
|
+we'll add a lesson "15-b" with a microkernel design. Who knows.
