Tupai is a modular operating system targeting the i386, x86_64 and armv7 architectures.

Objectives

Designed from the ground up in the Rust programming language, Tupai focusses on achieving the following objectives.

• Safety
• Stability
• Correctness
• Modularity
• Portability

Platform support

Currently, Tupai targets only 3 instruction set architectures; i386, x86_64 and armv7. However, Tupai is deliberately designed to make future ports to other architectures simple and painless.

Design

Much of Tupai's design is inspired by the POSIX specification, but compliance is not an objective.

Building

To build Tupai, first clone the project into a local directory.

git clone --recursive-submodules git@github.com:tupai-os/tupai.git && cd tupai

To build an ISO, execute the following command.

python build.py --target=<tgt> build

Where <tgt> is the desired target. To see supported targets, execute the following command.

python build.py --targets

Note: You can chain actions together like python build.py --target=x64 build test.

Testing

Once compiled, Tupai can be tested using an emulator. To test using QEMU (the default), execute the following command.

python build.py --target=x64 --emu=qemu test

Naming

Tupai is named after the Malay word for 'squirrel'.

Contributing

Currently, Tupai is not accepting third-party contributions due to its status as a final year university project. However, after May 2018 Tupai will begin accepting pull requests and issues.
