## Architectures

Currently, I try to support the architectures listed below. Currently, I'm only working on the x86_64 Support, but x86, ARM and AArch64 are following. In the following table you can see the status of every supported architecture

| Architecture  | Status | CPUID | Control Registers | GDT | IDT            |

|---------------|----------------|----------------|------------------|----------------|----------------------------|

| x86_64        | 🚧 In progress | ✅ Finished     | ✅ Finished      | ✅ Finished     | ✅ Finished              |

| x86           | 🚧 In progress | ✅ Finished     | ✅ Finished      | ✅ Untested     | Planned       |

| ARM           | 📌 Planned     | Planned        | Planned          | Not available  | Not available |

| ARM64/AArch64 | 🚧 In progress | Planned        | Planned          | Not available  | Not available |

## Credits

I have to give some credits for a few assembly instructions or information about architectures and code design ideas. Here is a list.
