**Cervus** - This is a modern 64-bit operating system written for the x86_64 architecture. It is currently under development.
|

|
## Technical Features
|
|
|
|
Cervus is currently in the active development phase. The kernel implements core low-level primitives required for a stable execution environment:
|
|
|
|
### Core Architecture
|
|
|
|
- _Boot Protocol:_ Utilizes the [Limine](https://github.com/limine-bootloader/limine) bootloader (Barebone profile).
|
|
- _Memory Management:_
|
|
- _PMM:_ Bitmap-based Physical Memory Manager.
|
|
- _VMM:_ Virtual Memory Management with 4-level paging support.
|
|
- _CPU Initialization:_ Custom GDT (Global Descriptor Table) and IDT (Interrupt Descriptor Table) implementation.
|
|
- _Acceleration:_ Native support for _SIMD_ instructions (SSE/AVX) with proper state saving.
|
|
|
|

## Build Environment
|
|
|
|
### Prerequisites
|
|
|
|
To build Cervus, you need a cross-compilation toolchain and the following utilities:
|
|
|
|
- _Compiler:_ `x86_64-elf-gcc`
|
|
- _Assemblers:_ `nasm`
|
|
- _Emulation:_ `qemu-system-x86_64`
|
|
- _ISO Tools:_ `xorriso`, `mtools`
|
|
|
|
### Compiling and Running
|
|
|
|
_1. Clone the repository:_
|
|
|
|
```bash
|
|
bash
|
|
git clone https://github.com/VeoQeo/Cervus.git
|
|
cd Cervus
|
|
```
|
|
|
|
_2. Compile and launch in QEMU:_
|
|
|
|
```bash
|
|
./build run
|
|
```
|
|
|
|
_3. Deploy to hardware (Flash Drive):_
|
|
**WARNING: This will overwrite data on the target device.**
|
|
|
|
```bash
|
|
sudo ./build flash
|
|
```
|
