Open Projects
Welcome! Whether you're here because of Summer of Code (SOC) or just want to scratch an itch to hack, we invite you to peruse our projects and ask about them on the RTEMS mailing list or IRC. If you plan to submit a proposal to do something for the RTEMS Project as part of a SOC, see Getting Started for SoC Students. RTEMS projects span kernel hacking, adding support for a new board (BSP), improving the development environment, developing tests, and more.
If you want to get your feet wet with RTEMS then check out our small projects page where you can find projects that require little coding skill and are appropriate for those new to RTEMS or open source software projects. If you are interested in one of these projects but are not able to code and test it yourself, consider sponsoring one of the core RTEMS developers to do it for you. Volunteering or sponsoring is how things get done -- users keep RTEMS development alive!
Most of these projects will take between a few weeks and a few months of effort by a person who is familiar with the general use of GNU/Linux and GNU tools. Many RTEMS projects are done by student or volunteer coders, so we try to define small projects or subtasks that can be completed and committed individually. Most of the projects are feasible as a Summer of Code project. Since some projects have multiple steps, students should work with prospective mentors to define the scope of work in their proposal. Similarly, some projects might be a starting point for a class project or graduate thesis.
Table of Contents
Overview
The order of projects in the list does not reflect their importance, difficulty, or feasibility. Our project list is not exclusive: if you have an idea, solicit feedback from the project's mailing list or IRC channel; many developers sit in IRC and check it (and their email) infrequently throughout the day, so be patient! There may or may not be enough work on a project to constitute an SOC project, and some of these are past SOC projects. If you are interested in one of these, please ask on the mailing list or IRC.
Projects in Bold text are higher priority simply meaning that users or developers have expressed a lot of interest in such projects. Projects in Italic text have had some work done and may need an updated description, might be complete already, and may or may not have sufficient work remaining.
If you have a new project add it to the appropriate list below, link to a wiki page below Projects/Open/? and use the Open Project Template. Briefly (1 sentence) summarize the project.
If one of the projects sounds interesting, but lacks detail, ask on an RTEMS mailing list for details and we can all help scope the project.
Testing
Testing a large body of software like RTEMS is in a continual state of improvement. There is always a need for more test cases and easier ways to run them all and decode the results. In addition, we want to be able to run all tests on as many hardware and simulator configurations as possible. Testing doesn't sound exciting to most people but when you combine the breadth of what we need to test with our desire for 100% instruction and branch path coverage, you get some very interesting and challenging work.
Some of the identified activities which would augment our testing capabilities are listed here:
- RTEMS Testing - General testing framework for RTEMS.
- RTEMS Test Specification - Develop a formal test specification.
- RTEMS Test Screen Validation - Create a tool to validate test output.
- Improve Coverage Analysis - Strive for 100% coverage.
- Simulator Updates - Find and fix problems in BSPs that target simulators.
- Testing of the GNU Tools - Improve Tools Testing on RTEMS targets
- POSIX Compliance Test Suite Develop cross-platform POSIX API Compliance tests (Ticket #2262).
- RTEMS Test Template - Improve automatic generation of tests.
- Fault tolerance - get a fault injection tool to work with RTEMS and create tutorials and examples.
Tools and Development Environment
RTEMS applications are cross-compiled on a development host to produce executables that are transferred to and executed on target systems. The projects in this section focus on the host side of that equation. This means they will run on a developer's computer and possibly communicate with embedded hardware.
The following areas have been identified for projects related to improving RTEMS development:
- Static Analysis of Stack Usage - Develop a tool for static analysis of stack usage.
- Python Coverage Reporting - Convert coverage reporting to Python and integrate into RTEMS Tools.
- RTEMS Test Improvements - Improve RTEMS Tester (rtems-test) by adding simulator recipes for more simulators.
- GCov Reports - Use gcov output as generated by covoar to generate useful reports.
- GProf Reports - Use gprof output as generated by covoar to generate useful reports.
- Improve RSB - General improvements to the RTEMS Source Builder?.
- Projects/Open/AddCoverageToGDBSimulators - Add execution coverage logging/reporting to the simulators supported by GDB and used by the RTEMS Project.
- Improve Eclipse Plugin - Improvements in the RTEMS Eclipse Integration.
- Python GDB Support - Add Python Script support for debugging RTEMS with GDB.
- Using clang - Compiling RTEMS with CLANG.
- eVisual Studio - Integration of RTEMS cross development environment into eVisual Studio.
- Projects/Open/ArgoUML - UML for RTEMS.
RTEMS Run-Time Oriented
The projects in this category are more focused on the development of software that runs on RTEMS on target hardware.
Executive (SuperCore, SuperCoreCPU, libcpu): a.k.a. kernel
- Improvements to SMP support - Identify and propose an improvement to the existing SMP capabilities.
- Condition Variables for the Classic API and supercore.
- Unified Interrupts - Unify the interrupt and PCI interfaces.
- Rump Kernels - provide the hypercall interface for Rump Kernels in RTEMS.
- Nested Mutexes: See Ticket #2124 for a problem description.
- TinyRTEMS - Improve some aspect of TinyRTEMS with any activities or ideas that could shrink the code and data memory requirements for RTEMS.
- Paravirtualization of RTEMS to make it suitable to be run as a guest OS in a hypervisor.
- RTEMS Sequenced Initialization is a project to allow RTEMS initialization to be dynamically constructed based upon user requirements. It would be like C++ global constructors conceptually.
Debugging
- Run-Time Tracing - includes gathering, capturing, and displaying information to the user. We are looking for more trace improvements and visualization.
- CPU Statistics - Improvements to CPU Usage Statistics.
- Stack Checker - Improvements to Stack Bounds Checker.
Board Support Package (BSP)
- Beagle BSP improvements - More peripherals and other improvements for the Beagleboard family.
- Raspberry Pi improvements - More peripherals and other improvements for Raspberry Pi.
- x86 BIOS emulation for VESA - This is Pavel Pisa's idea.
- Port RTEMS to Microblaze architecture? - New architecture port.
- More BSPs for Simulators - RTEMS can always use more BSPs for simulators (and readily available boards or open cores).
- Memory Protection - Implement MMU low-level support code for more BSPs.
- Merge Leon - Merging Gaisler LEON support code into mainstream RTEMS.
- Raspberry Pi2? - on hold due to unavailability of open information
- x86 Edison? - on hold due to unavailability of open information
API Layers (POSIX, Classic, SAPI)
- POSIX Compliance? - Improve POSIX compliance for RTEMS. Some projects: rename(), List IO, newlib.
- Projects/Open/OSEK - Implement OSEK APIs.
- Programmable Logic Controller - Implement IEC 61131 standard to enable RTEMS as a Programmable Logic Controller (PLC). More information on the IEC 61131 standard can be found at http://www.plcopen.org/ . http://www.beremiz.org/ is an open source framework for automation that may be a useful starting point.
- ARINC653 API support within RTEMS ARINC653API?
rtems-libbsd
- Update the RTEMS TCP/IP stack? - The networking stack in the main source tree is old and showing it. This project is actively underway. At a high level, this effort requires porting the TCP/IP stack and providing support functional equivalents of multiple BSD kernel constructs. This project has many subprojects many of which may be appropriate for SOC. Given that the stack is working now along with USB, ask about possibilities about Ethernet over USB and Wifi support.
- port BSD USB stack - This project is complete for some device types. Needs documentation and possible addition of other device types.
Languages
- Mono On RTEMS - Add support for Mono.
- Port V8 JavaScript Engine to RTEMS - Add support for the V8 Engine.
- SWIG on RTEMS - Add support for SWIG.
Libraries and Applications
- Port the Monkey HTTP Server and supporting infrastructure to RTEMS. Beyond simple porting, this includes submitting patches as needed to the Monkey project, providing a recipe for the RSB, an example and any instructions needed.
- Identify and implement the functionality currently missing in dup()
- Port Transparent IPC (http://tipc.sourceforge.net/index.html) to RTEMS
- Implement a Simple Line Editor. Existing code can be refactored for a starting point.
- Dynamic Object File Loading (RTL)? lets a base application with RTEMS dynamically load the rest of the application. The dynamic parts can be optional features and never loaded, or upgraded replacements for parts of the application.
- RTEMS Toolkits - We are defining collections of libraries and support programs which make it easier to get started for certain types of applications. We haven't identified all potential toolkits or components. Each potential component must be evaluated for license and appropriateness for use in an embedded environment like RTEMS. We also should define some guidelines about creating and maintaining toolkits in general. The eventual goal is to have these toolkits buildable by the RTEMS Source Builder. Here are the toolkits areas identified so far:
- Define a generic (RTEMS Source Builder based) infrastructure for building and maintaining toolkits.
- RTEMS BenchKit - benchmark programs for RTEMS
- RTEMS ConfigKit - configuration file parsing libraries
- RTEMS DBKit - database packages
- RTEMSGraphicsToolkit - various graphics and video processing. This kit has had some work done on it.
- RTEMS SciKit - libraries of general use to the scientific community RTEMS users
- RTEMS ScriptKit - packages for scripting languages such as Python and Lua
- RTEMS WebKit - packages for networked devices.
- Turn the current port of LWIP into a first class citizen that RSB can build. Submit port, make target independent, create maintenance plan.
- Make Addon Package? - write a tool to help other developers with Libraries, Languages, and Applications
Retired Projects
The following projects are complete or pending.
- Testing
- Tools
- Runtime
- Sixty-Four Bit Timestamps
- Refactor the filesystem infrastructure
- Use Maps or Hashes? in the implementation of Classic API Notepads and POSIX API Keys.
- Bdbuf improvements. The current block device buffer implementation can benefit from a number of improvements.

- kqueue(2) or taskqueue(9) is a project to port the kqueue(2) or taskqueue(9) API from FreeBSD.
- ISO9660 file system
- POSIX Asynchronous IO?. POSIX Asynchronous IO should be nearly done, with perhaps a little more work to do. POSIX List IO is not currently implemented. This would involve implementing and fully list IO per the POSIX specification as well as completing the Asynchronous IO. First step work is to save the state of the project as a report under the appropriate GSOC/YYYY year topic.
- Languages
- Parrot On RTEMS
- GNU GCC Go?
- RTEMS port of the GNU Java Compiler (gjc)
- Lua in RTEMS
- Porting RTEMS to OpenRISC.
Obsolete Projects
Some projects have been proposed that are viewed as being of minor use. This list is meant to provide a way to avoid wasted effort on projects that are not widely desired. However, projects on this list might still be useful to someone, given a motivated individual to work on them.
- Various ideas have been proposed related to using RTEMS as a hypervisor?. The lack of protected (kernel mode) execution precludes any feasible implementations.
- Merge BSP for Simplescalar simulator?. The BSP is heavily bit-rotted and the simulator is a dead project.
- Rosetta OS OS Independent Device Driver API?.
- Implement current version of µITRON Interface http://www.www.tron.org/index-e.html. itron support was removed from RTEMS due to lack of interest.
- More NIC device drivers?. See instead TCP/IP update?.
- Integrate CEXP? into main RTEMS distribution. Possible licensing issues, please apply to the RTL project instead.
- Scripts and documentation for creating and installing prebuilt tool packages Building Tool RPM Packages?, Debian Packages?, MacOS tools?, MinGW Tools for Windows, Canadian Cross Compiler?. Please apply to the RSB project instead.
