mmio

Define and operate on type safe MMIO

Unified interface for type-safe MMIO and CPU register access in Rust

A Rust library crate with types for safe MMIO device access

Lightweight MMIO for Kotlin Multiplatform.

Minimal VMM implementation - KVM hello world example (learning purpose)

Four Linux kernel modules — character device, block device (blk-mq), network device (NAPI), and PCIe (MMIO/MSI/DMA) drivers — built and tested end-to-end in Docker + QEMU.

Unlock H-series CPU performance that Lenovo's EC firmware locks away on consumer IdeaPad/V/ThinkBook laptops — for Linux and Windows. MMIO Lock technique (ThrottleStop equivalent for Linux). 2.6× Geekbench multi-core speedup on V17 G4.

A fast Linux driver based on single-producer single-consumer ring buffers to control a sample accelerator.

A Swift library for peripheral I/O (GPIO, LED, PWM, SPI, I2C, MMIO, Serial) in Linux.

rt26cx21x64.sys exploit (Realtek PCIe GbE/2.5GbE/5GbE family)

TUI PCI register viewer — scan GPU devices, read config space, mmap BAR registers (NVIDIA/AMD/Intel)

Read and write a memory-mapped SiFive system-on-chip UART

Low-level hardware register editor.

Runnable AXI4-Lite master/slave RTL verification lab with UVM regressions, reference models, SVA and QuestaSim scripts.

An ambitious attempt at documenting the bl602 better then the manufacturers themselves did through practical little code examples

drapl is a Linux daemon that dynamically applies RAPL power limits based on system power states

C99 library for unit testing embedded drivers without hardware. Models 32-bit MMIO registers, W1C/read-clear bits, and access traces; no heap.

Hands-on ARM Cortex-M3 labs for embedded systems development, debugging, CMSIS, ARMv7-M architecture, QEMU, GDB, and GNU Arm Embedded Toolchain.

End-to-end embedded Linux driver project for a custom QEMU-emulated MMIO mailbox device. Implements a QEMU `virt-mbox` SysBusDevice and Linux `vmbox` platform character driver exposing `/dev/vmbox0`, with FIFO-backed I/O, interrupts, `poll()`, ioctl UAPI, sysfs/debugfs observability, and an ARM64 QEMU boot demo.
