- Assembly - x86
- C - know the basics from C++ and brief experience. My OS is totally C++, with many Object Orientated elements.
I learnt a large amount of basic C++ through my OS. I used the brokenthorn OS as my OS for a while, and at it's height I was working on loading programs.
I decided to restart and do my own coding. I now have a white CLI on a light blue background in PMode and CLI functionality, with PCI probing and a simple VFS (along with a disk management system I call the VDS)(Both implemented as classes) I also have a simple VGA graphics screen. I now probably can be called a C++ guru as I know how to manipulate pointers and references, as well as classes. I still find asm a bit cluttered if the algorithm is complex, but if I'm doing my kernel in C++ I only need to provide basic asm routines.
My Setup
Overview
I have a OS that is going to support x86 and AMD64 (with an actual 64 bit version). For testing purposes I am currently using the BrokenThorn bootloader. I am adabting it for 64 bit purposes, but my target setup is my own bootloader on a HDD (MBR currently working).
Assembler
I use NASM as my assembler, in conjunction with the Notepad++ editor.
Compiler/Linker
I use the unusual, but productive and familiar, environment provided by Visual C++ 2010 Express (SP1). I installed the windows SDK (update for SP1) for the 64 bit compilers. Because Visual C++ doesn't support 64 bit inline asm or naked functions I use this type of setup:
//Asmlayer.h - 32 bit and 64 bit
#ifdef __cplusplus
extern "C" {
#endif
void disable();
//other function declarations go here
#ifdef __cplusplus
}
#endif
And in my asm code:
;Asmlayer.asm - 32 bit version
BITS 32
global @disable@0 ;all will be revealed
;other declarations go here
@disable@0:
cli
ret
;Asmlayer64.asm - 64 bit version
BITS 64
global disable
;other declarations go here
disable:
cli
ret
Note the fastcall convention - 64 bit VC++ only supports fastcall. I use the integrated editor for C/C++, and Notepad++ for asm (syntax highlighting)
Controversial issues
I use gotos. Sometimes I come across an algorithm I've just written and there are to options: rewrite the algorithm or use the goto. For lack of time to rewrite the algorithm, I use a goto. Don't get me wrong, I'm a fan of neat code. However, there are times when I use a goto and the odd goto doesn't mess up neatness. Admittedly, a algorithm full of gotos would be hard to follow around (like asm), but the odd goto is like using the odd break statement. That is my opinion.
Emulator
I use several emulators, but for testing purposes it has to be bochs.
Development/Test PC
For development I use an HP Pavilion g6 (6GB RAM, quad-core 1.5 GHz AMD A8 3500M, 1TB HDD), with Windows 7 64 bit home edition.
For testing I will use emulators, then once fairly trusted I will place on a HP Pavillion 6405 (64MB RAM, 6GB HDD, 400Mhz Celeron), which currently has Win98 SE dual-booted with Linux Mandrake 7. Once I have tested HDD's completely, I will place it on a small partition of my development PC (64 bit testing).
My OS
My OS is an 32/64 bit x86 OS. It currently has a CLI implemented in a grpahics mode, and virtually no drivers (basic chip drivers only). It WILL be extended to HDD's and use a custom file system, CFS.
