RISC-V Emulator and Linux System from Scratch

This repo contains all the source code required to follow the blog post at https://werwolv.net/posts/linux_bringup/

Source Code

/lib contains the entire rv32ima instruction set emulator code as well as a minimal set of emulated devices
/main contains the configuration for our machine and functions exposed for WebAssembly use

Configuration

All the config files required to build Linux can be found in /boot. The main executable also expects all the built binaries to be in the boot folder.

riscv32-unknown-linux-gnu.config is the crosstool-ng toolchain config file
riscv_emulator_defconfig is the Linux Kernel config file
device_tree.dtsis the minimal device tree
Can be compiled to a dtb using dtc -I dts -O dtb device_tree.dts -o device_tree.dtb
init.cis the init program
Can be compiled using riscv32-unknown-linux-gnu-gcc -static init.c -o init
initramfs.txt is the gen_init_cpio config file to generate the initramfs
Can be compiled to a cpio using usr/gen_init_cpio initramfs.txt -o initramfs.cpio

＋ POSITIVE40%

A significant advancement in open-source computing has been unveiled with the creation of a comprehensive RISC-V emulator and a fully functional Linux system. This project, available on GitHub, offers a complete suite of source code, detailing the entire process of building a Linux environment on the RISC-V architecture from the ground up. The emulator itself supports the rv32ima instruction set and includes a minimal set of emulated devices, paving the way for deeper exploration and development.

− NEGATIVE10%

A new open-source project has emerged, offering a RISC-V emulator and a Linux system built from the ground up, but its practical utility and stability remain questionable. While the repository claims to provide all source code for a Linux bring-up, the project is still in its nascent stages, evidenced by its low star count of 18 and a single fork on GitHub. This suggests limited community engagement and validation thus far.
