FrostVista OS (霜见内核)

FrostVista is a personal experimental OS kernel targeting RISC-V.

It is not meant to be a full-featured general-purpose OS.
The goal is to build a clear, readable, and hackable playground for:

• low-level RISC-V
• memory management and paging
• traps, interrupts, and syscalls
• scheduling and simple filesystems
• later: real RISC-V boards

This is a long-term project. Expect rough edges and frequent rewrites.

Build & run

Note: commands and paths here are placeholders.
Adjust them to match your actual toolchain and directory structure.

Requirements (planned):

• RISC-V cross toolchain (e.g. riscv64-unknown-elf-gcc)
• make
• qemu-system-riscv64

Typical flow:

# build kernel
make run

On success, you should see a short boot message from FrostVista over the serial console.

Philosophy

• Prefer clarity over cleverness, and structure over features.
• Keep the kernel small enough to read and reason about.
• Treat this codebase as a long-term notebook for systems experiments.

If you are interested in OS dev, RISC-V, or low-level experiments, feel free to read, fork, or open an issue to discuss ideas.
