vineyard

A work-in-progress hobby operating system for x86_64.

Status

Currently implemented features include:

• ACPI, implemented via ACPICA: for shutdown and PCI IRQ resolving
• NVMe: read-only support
• ubsan: for catching undefined behavior

Roadmap

Priorities in the future:

• Support for filesystems: FAT (for the EFI partition) and one for the root partition (maybe btrfs?)
• libc cleanup:
  • namespace pollution, including use of stdint.h types
  • Stack Smashing Protector
  • proper C and POSIX compliance
• timing via HPET
• functional user-space
  • think about turning this into a microkernel?
• SMP
• Intel HD Graphics drivers
• Intel HDA

Prerequisites

Required:

• a Unix-ish OS with bash
• Python 3, preferably >= 3.7
• Python's PyYAML
• xbstrap
• Kconfiglib, a Python reimplementation of Linux' Kconfig-related utilities
• mtools, for working with FAT images
• mkfs.btrfs
• QEMU
• yasm
• clang
• lld

Optional:

• VirtualBox, with the Extension Pack installed (required for NVMe support!)
• VMWare

Building

Clone the repo vineyard-os/bootstrap into the project folder vineyard.

git clone https://github.com/vineyard-os/bootstrap vineyard
cd vineyard

In the root folder vineyard, set up xbstrap and run it:

xbstrap init .
xbstrap install --all

To test vineyard in QEMU, run this from the root project folder:

make -C vineyard test
