QEMU Camp 2026 — Experiment Repository

English | 中文

This is the professional-stage experiment repository for QEMU Camp 2026. It covers four experiment directions, all based on RISC-V.

Direction	Experiment Manual	Hardware Datasheet / Guide
CPU	CPU Experiment Manual	CPU Datasheet
SoC	SoC Experiment Manual	G233 SoC Datasheet
GPGPU	GPU Experiment Manual	GPU Datasheet
Rust	Rust Experiment Manual	Rust Programming Guide

Full tutorial site: https://qemu.gevico.online/

Direction	Test Framework	Test Location	Scoring
CPU	TCG testcase	tests/gevico/tcg/	10 tests x 10 pts = 100
SoC	QTest	tests/gevico/qtest/	10 tests x 10 pts = 100
GPGPU	QTest (QOS)	tests/qtest/gpgpu-test.c	17 tests -> 100 pts
Rust	QTest + unit	tests/gevico/qtest/ + rust/hw/i2c/	10 tests x 10 pts = 100

Implement custom RISC-V instructions for the G233 machine. Tests verify instruction behavior via semihosting-based bare-metal programs.

• Machine: g233 (hw/riscv/g233.c)
• Tests: tests/gevico/tcg/riscv64/test-insn-*.c
• Run: make -f Makefile.camp test-cpu
• Docs: Experiment Manual | CPU Datasheet

Implement peripheral device models (GPIO, PWM, WDT, SPI, Flash) for the G233 SoC. Tests verify register behavior and interrupt connectivity via QTest MMIO read/write.

• Peripherals: GPIO (0x10012000), PWM (0x10015000), WDT (0x10010000), SPI (0x10018000)
• Tests: tests/gevico/qtest/test-*.c
• Run: make -f Makefile.camp test-soc
• Docs: Experiment Manual | G233 SoC Datasheet

Implement a PCIe GPGPU device with SIMT execution engine, DMA, and low-precision float support. Tests verify device registers, VRAM, kernel execution, and FP8/FP4 conversions.

• Device: hw/gpgpu/ (PCI device gpgpu)
• Tests: tests/qtest/gpgpu-test.c (17 subtests)
• Run: make -f Makefile.camp test-gpgpu
• Docs: Experiment Manual | GPU Datasheet

Implement I2C bus, GPIO I2C controller, and SPI controller in Rust for the G233 SoC. Unit tests verify core Rust logic; QTest tests verify device register behavior and peripheral communication (AT24C02 EEPROM over I2C, AT25 EEPROM over SPI).

• I2C bus: rust/hw/i2c/src/lib.rs (3 unit tests)
• GPIO I2C controller: base 0x10013000, connected AT24C02 EEPROM (addr 0x50)
• SPI controller: base 0x10019000, connected AT25 EEPROM
• Tests: tests/gevico/qtest/test-i2c-*.c, tests/gevico/qtest/test-spi-rust-*.c
• Run: make -f Makefile.camp test-rust
• Docs: Experiment Manual | Rust Programming Guide

• Tests that fail do not break CI — they simply result in a lower score.
• Scores of 0 are not uploaded to the ranking platform.
• Each push to main triggers a full CI run.
