This project is a combination of projects to develop and test QEMU, OpenSbi and Linux kernel for RISC-V. You can use this project to develop and test
- Simulator: QEMU
- Firmware: RISC-V Open Source Supervisor Binary Interface(OpenSBI) is supported currently
- Kernel: Linux kernel
- User programs: Not support yet(support prebuilt file system)
To fetch the project source files, use command below. It will need several minutes to clone all the project source files.
$ mkdir qemu-linux-riscv && cd qemu-linux-riscv
$ repo init -u https://github.com/SimonSungm/manifests -b main -m qemu-linux-riscv.xml
$ repo sync -v -j4
$ cd build_tools/prebuilt
$ git lfs pull
When cloning the project source file, it may cause following errors. Just ignore it.
curl: (22) The requested URL returned error: 404 Not Found
Unable to retrieve clone.bundle; ignoring.
The source files do not include riscv-gnu-toolchain since it is too big and takes too long to build. Therefore, you need to build the toolchain by yourself and install it in qemu-linux-riscv/toolchain. You can use following instructions to build the riscv-gnu-toolchain.
$ cd qemu-linux-riscv
$ git clone https://github.com/riscv/riscv-gnu-toolchain.git
$ mkdir toolchain
$ PREFIX_PATH=`pwd`/toolchain
$ cd riscv-gnu-toolchain
$ ./configure --prefix=$PREFIX_PATH
$ make
$ make linux
You can use make to get the help available targets to build.
$ cd qemu-linux-riscv
$ make
Usage: make [target]
Tagerts:
build: Build all necessary images needed to run qemu
Note: riscv-gnu-toolchain is needed
run: Run qemu, use DEBUG=on to enable deug mode
linux: Build linux kenrel image
qemu: Build qemu simulator
opensbi: Build opensbi image
clean_linux: Clean linux kenrel target files and image
qemu: Clean qemu target files and image
opensbi: Clean opensbi target files and image
clean Clean all target files
Build the project and run qemu
$ make build
$ make run
