# HLeOs ## Description. **HLeOs** is an toy operating system programed by Rust language, on amd64 system. \ made by HLe4s, a system programmer and a student in [sslab](https://sslab.ajou.ac.kr/), Ajou Univ. ## Environment. **HLeOs** can be run on qemu-system-x86_64, and on amd64 PC. \ but, It's code have some randomness.. (see init kmalloc,in src/main.c) \ so An amd64 PC may not run **HLeOs** If you want running **HLeOs** on your PC. you can use "Win32 disk imager" program. ## Prerequisite **HLeOs** is programed by Rust language. so you should prepare rust cargo.

(before init_stack(), in main.rs)  - src : a directory, have source files of **HLeOs** - src/main.rs : **HLeOs**'s kernel main - src/etc.rs : **HLeOs**'s etc functions.. - src/hleos : a module about **HLeOs**'s kernel function. - src/hleos/asm.rs : rust inline asm code blocks - src/hleos/interrupt.rs : funcs about interrupt, GDT, IDT, TSS .. etc - src/hleos/interrupt/handler.rs : interrupt and exception handlers - src/hleos/iostream.rs : keyboard service.

Deprecated README.md ( ~ 2022.05.13 ) ---------------------------------------------- # HLeOs HLeOs, a educational operating system programed by rust. ----------------------------------------------------- show some descriptions about this project. in my blog, .. it 's in korean [myblog](https://hacking-yi.kro.kr "my blog") ### 01. how to debug boot loader in real mode debugging [ko] Makefile , gdb-i386 debug-loader . boot loader . qemu-system-i386 , gdb realmode , x86_64 . , realmode . . 1. . 2. "make ; make gdb-i386" . 3. "make debug-loader" . 4. . , file ;; ++ symbol . [en] you can find two rules in Makefile, 'gdb-i386', 'debug-loader' this two rules are used to debug the boot loader in real mode. I made 'gdb-i386' because, when I debug boot loader in realmode, It makes an error to use 'qemu-system-x86_64' so I made restrictly the two rules. How to debug loader 1. open two terminal 2. in one, type "make ; make gdb-i386" 3. in another, type "make debug-loader" 4. debug ! # file command makes error :( ++ you can make symbol by using 'symbol' command
