priority-inheritance

Projects implemented on XINU OS. Process Scheduling, Demand Paging, and Concurrency Control.

Design notes for a Rust and Tokio runtime that promotes a stalled async task to a blocking thread when other tasks depend on it, a form of priority inheritance. No code yet.

[EN-US] A Python GUI process scheduling simulator demonstrating priority inversion, priority inheritance protocol, and Gantt chart metrics. [PT-BR] Simulador gráfico de escalonamento de processos em Python com suporte a inversão e herança de prioridade e visualização via gráfico de Gantt.

Hand-written preemptive RTOS kernel for STM32F407 — ~700 lines, zero malloc, bitmap scheduler, PendSV, priority inheritance

Preemptive RTOS from scratch for Arduino Uno (ATmega328P) in C + AVR assembly. Priority scheduler, semaphores, queue, priority-inheritance mutex. No Arduino framework, no extra hardware, ~2.2 KB flash. Measured and documented.

A deterministic real-time operating system (RTOS) scheduling and verification engine in C++17 featuring Rate Monotonic (RMS), Earliest Deadline First (EDF), and Priority Inheritance Protocol (PIP).

📄 Priority Scheduler with use of semaphores

Solving priority inversion in a preemptive real-time kernel for ARM Cortex-M7: dynamic-priority scheduler + priority-inheritance mutex, demonstrated on QEMU (UTC MI11)

A deterministic embedded RTOS kernel featuring priority inheritance, deadlock detection, advanced IPC primitives, and dual-strategy memory management.

Real-time scheduling and synchronization project implementing EDF, RMS, mutexes, priority inversion, and priority inheritance.

Deterministic RTOS simulator in Rust: preemptive scheduler, priority inheritance, mutexes, queues

This repository contains a series of lab tutorials designed to explore Real-Time Operating Systems (RTOS) using RTEMS on the ERC32 simulator.

Demonstrating the priority inversion bug in FreeRTOS, and the priority inheritance implemented in FreeRTOS, while implementing another priority inheritance method.
