Starry

Introduction

The main repository of Starry-OS, which will assemble all kernel components into a kernel according to a certain configuration.

This repository is based on Starry, and remove submodules from the kernel, placing them here.To use these crates in the local workspace, please see the Pull crates to local workspace section.

Structure

Build and run

# Run in unikernel architecture

# $ make A=apps/<app_name> ARCH=<arch> run

# The <app_name> is the application stored in the ./apps folder.

# The <arch> can be x86_64, risc64 and aarch64.

$ make A=apps/helloworld ARCH=x86_64 run

# Run in monolithic architecture

# Make the testcases image first

# $ ./build_img.sh <arch>

$ ./build_img.sh -a x86_64

$ make A=apps/monolithic_userboot ARCH=x86_64 run


# Run the testcases in the monolithic architecture

$ make A=apps/monolithic_userboot APP_FEATURES=batch ARCH=x86_64 NET=y BLK=y run

Build and run testcases with ext4fs

The document of the ext4fs is here.

# Build the image in ext4fs
$ ./build_img.sh -a x86_64 -fs ext4

# Run in the lwext4fs with Rust interface, whose url is https://github.com/elliott10/lwext4_rust.
$ make A=apps/monolithic_userboot FEATURES=lwext4_rust LOG=off NET=y BLK=y ACCEL=n run

# Run in a new ext4fs written in Rust, whose url is https://github.com/yuoo655/ext4_rs.
$ make A=apps/monolithic_userboot FEATURES=ext4_rs LOG=off NET=y BLK=y ACCEL=n run

# Replace virt-io with ram-disk
$ make A=apps/monolithic_userboot FEATURES=ext4_rs,img LOG=error NET=y BLK=y ARCH=x86_64 ACCEL=n run

# Run testcases for OSCOMP
$ make A=apps/monolithic_userboot FEATURES=ext4_rs,img LOG=off NET=y BLK=y ACCEL=n run APP_FEATURES=batch

Pull crates to local workspace

# To download the tool
$ cargo install kbuild

$ mkdir crates

# Load crates
$ kbuild patch add linux_syscall_api

$ kbuild patch add axstarry

# Then crates will be downloaded to the crates/ folder

# To remove the crates
$ kbuild patch remove linux_syscall_api

$ kbuild patch remove axstarry

# Please verify that crates don't have any uncommitted changes before removing them.

Run with e1000 driver

$ make A=apps/monolithic_userboot FEATURES=img,sched_rr,e1000_net LOG=off ACCEL=n APP_FEATURES=batch NET=y BLK=y run 

Notes

• Please remove unnecessary dependencies in Cargo.toml before your commit.
• After pulling a new crate to the local workspace, maybe you need to execute make clean to update the cache.
