README

Penglai Header

This repo maintains sPMP version of Penglai Enclave.

Info

OpenSBI-based Penglai is maintained in Nuclei SDK now.

Quick Start

Penglai uses Docker for building and uses submodules to track different componets.

Therefore, the only requirement to build and run penglai-demo is:

Docker: for building/running Penglai
Git: for downloading the code

The version for FPGA and RISC-V board is comming soon.

Building

First, download the all the code:

git clone https://github.com/Penglai-Enclave/Penglai-Enclave-sPMP.git

Enter the penglai-enclave directory, cd Penglai-Enclave

And then,

git submodule update --init --recursive

Last, build penglai using our Docker image:

./docker_cmd.sh build

When the building process finished, you are ready to run the penglai demo.

Running

In the penglai-enclave directory,

./docker_cmd.sh qemu

If everything is fine, you will enter a Linux terminal booted by Qemu with Penglai-installed.

Enter the terminal with the user name: root, and passwords: penglai.

Insmod the enclave-driver

insmod penglai.ko

And the, you can run a demo, e.g., a prime enclave, using

./host prime

Here, the host is an enclave invoker, which will start an enclave (name from input).
