jinix

An academic operating system in rust for my IS capstone

Design choices

Overall

• Build the kernel

Hybrid kernel (A mix of monolithic and micro kernel design)

• Drivers are compiled with the kernel (Like a monolithic kernel)
• Message passing seems like an interesting challenge. Look at L4 for optimized message passing
• Processes

Memory Management

• The Ox64 has the Sv39 MMU
• Having virtual memory addresses is good for isolating processes logically

Config Files

• Put into a directory for config? like /etc/ but dedicated
• Store in yaml?
• Build an api like the windows registry in future iterations?

Shell

• Like bash/fish/python | Use tabs for indentation? :P
• Use a fewer set of characters because it would be nice to have a small keyboard.
• Include the most common characters from human langs, programming langs,

Hardware

• Build a split keyboard and have a vertical screen in the middle?
• Maybe around the size of a smaller smartphone
• One PCB and no battery to keep the design minimal/lean to start?
