The Linux Kernel is the core component of the Linux operating system—a free, open-source, monolithic, Unix-like system kernel initiated by Linus Torvalds in 1991 and since evolved into a foundational technology powering everything from servers and supercomputers to smartphones and embedded devices. There are various text files in the Documentation/ subdirectory, several of them using the reStructuredText markup notation. Extensive filesystem compatibility (ext4, Btrfs, FUSE, XFS, etc.) Broad...

The Zephyr Project is a new generation real-time operating system (RTOS) that supports multiple hardware architectures. It is based on a small-footprint kernel specially designed for use on resource-constrained and embedded systems. The Zephyr OS can be used for a wide range of applications: from simple embedded environmental sensors and LED wearables to sophisticated embedded controllers, smart watches, and IoT wireless applications.

...Rather than replicating traditional monolithic kernels exactly, it emphasizes modularity, safety, and simplicity by incorporating well-structured subsystems for memory management, scheduling, and device abstraction that are easy for contributors to understand and extend. The kernel uses Rust as its primary implementation language, which gives it strong memory safety guarantees and helps reduce common classes of bugs like data races and buffer overflows without sacrificing performance. It aims to serve as both a learning tool for systems programming students and a testbed for advanced research in kernel architecture, enabling experimentation with new ideas in process isolation, resource management, and driver models.

XanMod is a general-purpose Linux kernel distribution with custom settings and new features. Built to provide a stable, smooth and solid system experience. https://gitlab.com/xanmod/linux https://xanmod.org

Custom thread scheduler with custom data-structure and scheduling algorithm. Custom Mutex, Semaphore implementation and asynchronous messaging system that combines Observer and Visitor patterns. System is implemented on top of Windows system and not ported to any hardware, uses Windows thread for context saving. Code also has tested common data-structure implementation. System is designed for multi-core platform.

AVR ATmega port of freeRTOS A port of freeRTOS which can be flexibly flexibly configured use almost any available Timer on AVR ATmega devices and will operate with almost any classic Arduino device from Arduino, SeeedStudio, Sparkfun, Freetronics or Pololu. Going forward this repository will be updated less often and only with major releases. Please check at Github for the latest commits. https://github.com/feilipu/avrfreertos The Goldilocks Analogue story is told here....

This project is now in the research and development stage. It is intended for very small microcontrollers with a single processor and represent simple multithreading kernel what written by C language. Is planning create implementations for AVR8 and STM8, may be. Now it is suspended until better time.

...It presently supports the AVR and MSP430 architectures. The advantages of PRTOS are: It has the smallest footprint of any true preemptive system: 1.9kB for basic scheduling and task control, 5.1kB with all the features below (AVR '328 / gcc -Os); Only 950 lines of code implement all of the RTOS features (SLOC-L); The system is well documented with a comprehensive manual, well-commented source code, and a test suite demonstrating the features; The system is proven - it has been in use since 1982 with applications in in-vitro medical equipment, process control instrumentation and industrial machinery; PRTOS is released by Cleveland Engineering Design, LLC - developer of the CoRTOS cooperative RTOS https://sourceforge.net/projects/cortos-simple/ and the CTREE analysis tool https://sourceforge.net/projects/ctree-graphic-tree-generator/ Commercial licensing is available

It is programmed using Queue on JAVA You can change CPU Burst, CPU Speed, Add Process manually, ON/OFF

A Disk Scheduling Simulator tool. With an intuitive GUI interface and command line functionality. Built using both VC and VB. Currently supports SSTF,LOOK,CLOOK,SCAN and CSCAN algorithms. Rotational latency is also optionally supported.

L_Pa is a project / collection of tools aimed at better integration and *performance* of Linux + Wine + jackd + Proaudio applications... L_pa accomplishes this by setting up a proper mix of kernel/software with low-latency/proaudio users _specifically in mind. So far the main components are; Custom version of the (rt-)linux kernel with a delta of patches, for linux proaudio usage. Custom version of Wine with a delta of patches to ensure Wine is ready for proaudio on the linux...

This is a fork of FreeRTOS 7.3.0 using an earliest deadline first scheduler instead of the standard fixed priority scheduler BIG FAT WARNING: THIS IS HIGHLY EXPERIMENTAL SOFTWARE! USE AT YOUR OWN RISK! NEITHER REAL TIME ENGINEERS NOR THE AUTHOR(S) OF DEADLINERTOS PROVIDE ANY WARRANTY!

...Currently a simple context switching implementation for the XMOS XS-1 architecture (Gn, Ln products). Allows a user to run low speed processes on a single thread using time sliced scheduling.

Tasks often depend on each other because of inter-process communication/synchronization. Task dependency have significant impact on performance. swap-sched solves the problem by dynamically detects dependency and use it for scheduling.

K-OS is an open-source realtime-operating-system based on the OSEK/VDX standard aimed at compiler and microcontroller independence. Currently we support Motorola (Freescale) HC12/HCS12/HCS12X targets.

ATOS is a lightweight real-time operating system. It supports pre-emptive scheduling and intertask communication in embedded systems.

The ADSL optimizer is an accurate packet scheduling solution for ADSL connections, based on Linux and HTB. The solution guarantees low latency while maintaining full utilization of both upstream and downstream, without wasting link capacity.

Rt-Simulator is a library to simulate task behaviors on uni/multi-processors with different scheduling algorithms. It provides a run-time reference by fast-prototyping and it can also used for scheduling algorithm research simulation.

EQP - Eager Queue Protocol is a protocol that uses broadcasting to schedule processes across a local network of processors. It is intended to replace time sliced single thread scheduling in operating systems like GNU Hurd.

SangMyung Univ. Graduate Project Project: MyRTOS Team name:Software Craftsmanship Description: pxa255 based RTOS. Preemptive Multi-threading,Priority-base,Round-Robin Scheduling, Thread, Semaphore,Message Mail Box,Message Queue Management Support.

CPU Scheduler Evaluation (CPUSE) Patches to Linux and supporting software tools for controlling scheduling parameters and analysing and/or displaying scheduling statistics.

Trio extends the existing Linux scheduler to support proportional-share scheduling using a scheduling algorithm, called Distributed Weighted Round-Robin (DWRR). It allows users to control shares of CPU time for any thread or group of threads.

Console tool to set or change scheduling policy and realtime priority of other processes or start new processes with the respective scheduling. Child processes inherit scheduling. Access control by PAM (Pluggable Authentication Module) and Rlimits.

ftRTOS is a tiny realtime kernel for microcontrollers focused on minimal RAM usage. Fixed priority scheduling, preemptive or cooperative multitasking, no dynamic task and memory management, all objects are defined at compile time.

The Entitlement Based Scheduler (EBS) is a modification of the Linux O(1) CPU scheduler that introduces entitlement based scheduling for SCHED_NORMAL tasks.
