Learning purpose riscv64 (RV64GC) emulator. This project is built for 一生一芯 as a reference implementation.
Highlights
- Type-safe instructions which makes the decoding less error-prone.
- Full emulation trace (registers, memory, etc.) like persistent data structures, which is useful for debugging the real hardware.
-
MISA =
RV64ACDFIMSU- RV64G (IMAFD_Zicsr_Zifencei) instruction set
- RVC extension
- Supervisor mode extension
- User mode extension
Amazing Moments
Running openEuler Linux for RISC-V
Currently, the init program cannot use serial device as console (I am trying hard to find the cause).
But the kernel was indeed successfully booted and initialized.
I was thinking that should I just give up trying to fix the console problem, instead,
go and implement a virtio-net device and start the sshd service when booted?
It's not that hard comparingly, and it's closer to the real-world use case.
Running RustSBI-QEMU with its test kernel
With the following command:
cargo run --release -- --kernel tests/test-kernel.bin --bios tests/rustsbi-qemu.bin
Running xv6 for RISC-V
With the following command:
$(CROSS)objcopy -O binary xv6/kernel xv6/kernel.bin
cargo run --release -- --kernel xv6/kernel.bin --disk xv6/fs.img
