= Open Projects = Welcome! Whether you're here because of [wiki:GSoC 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 [wiki:TBR/Website/RTEMSMailingLists RTEMS mailing list] or [wiki:Developer/IRC IRC]. If you plan to submit a proposal to do something for the RTEMS Project as part of a SOC, see [wiki:GSoC/GettingStarted 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 [wiki:Small_Projects_ 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 [wiki:GSoC 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. [[TOC(Developer/OpenProjects, depth=2)]] = 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 [wiki:TBR/Website/RTEMSMailingLists mailing list] or [wiki:Developer/IRC 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 that follows the recommended [wiki:TBR/Review/OpenProjectTemplate Open Project Template], and briefly (1-2 sentences) summarize the project and how it will improve RTEMS. = 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: * ''[wiki:Projects/TestingImprovements RTEMS Testing]. Testing for RTEMS, including Unit, Regression operational and building a custom test harness. No prior knowledge of software testing is required. (SOCIS)'' * [wiki:GSoC/Projects/TestTemplate RTEMS Test Template] - Improve by adding functionality * [wiki:Developer/Testing/Specifications RTEMS Test Specification] - Need a formal test specification. Ideally, inspired by http://softwaretestingstandard.org/ some notes about existing test specifications can be found http://www.rtems.org/wiki/index.php/GoogleCodeInProjects#Test_Documentation_Files_update . * [wiki:RTEMS_Test_Screen_Validation RTEMS Test Screen Validation] - This requires expertise in a unit testing framework, probably DejaGnu, and will probably need to be tied into [http://git.rtems.org/rtems-testing/ rtems-testing]. * '''[wiki:RTEMS_Test_Coverage Test Coverage Analysis]''' - Improve coverage by adding more test cases. Eliminating dead code and reaching 100% coverage helps reduce the likelihood of new and recurrent bugs. (SOCIS) * Write a tutorial, modify a [wiki:TBR/Delete/Fault_injection Fault injection] tool to work with RTEMS * Test the [wiki:Projects/POSIXFIFOs POSIX FIFO Implementation]. * [wiki:RTEMSgprof_ Add support for gprof output to covoar] * Improve [wiki:Projects/GNUToolsTesting Testing of the GNU Tools] on RTEMS targets * ''[wiki:TBR/Delete/POSIXTimingTests POSIX Timing Tests]'' * ''Add [wiki:RTEMSgcov_ support for gcov output] to covoar so tools like gcov and lcov can be used with RTEMS ([wiki:Projects/GCOVSupport another page here])'' * ''[wiki:Projects/POSIXComplianceTestSuite POSIX Compliance Test Suite]'' * [wiki:Projects/Open/SimulatorUpdates Simulator Updates] - Test BSPs that target simulators to find and fix problems. (SOCIS) = 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: * Improvements in the [wiki:Developer/Eclipse/Information RTEMS Eclipse Integration]. * Compiling RTEMS with [wiki:Projects/CLANG CLANG]. * [wiki:Projects/Leon_rtems_merge Merge Leon RTEMS and mainstream RTEMS] merge the Leon [wiki:TBR/UserManual/DriverManager DriverManager], [http://gaisler.com/anonftp/rcc/src/ samples], and [https://github.com/daniel-hellstrom/leon-rtems/tree/master/c/src/lib LEON-RTEMS] into mainstream RTEMS. (SOCIS) * Integration of RTEMS cross development environment into [wiki:Projects/EVisualStudio eVisual Studio] * [wiki:Projects/ArgoUML ArgoUML RTEMS Support] * [wiki:Projects/GDB_Python GDB Python] Script support for RTEMS * [wiki:TBR/UserManual/RTEMS_Source_Builder RTEMS Source Builder] improvements such as building host tools, building a GUI, and improving configuration management and creation. = 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 = * ''[wiki:SMP_ Improvements to SMP support]'' - Multiprocessing is of increasing importance. This is a large project and subtasks should be identified before writing any proposal. * '''[wiki:Projects/Condition_Variables Condition Variables]''' for the Classic API and supercore. * Unified Interrupt and PCI APIs -- [wiki:UnifiedAPIs UnifiedAPIs] * [wiki:Projects/SystemEvents kqueue(2) or taskqueue(9)] is a project to port the kqueue(2) or taskqueue(9) API from FreeBSD. * [wiki:Projects/TinyRTEMS TinyRTEMS] is an umbrella term that corresponds to any activities or ideas that could shrink the code and data space requirements for RTEMS. The goal is to progressively lower the minimum CPU requirements. * Improve the RTEMS [wiki:SuperCore_Scheduler_ SuperCore Scheduler] * ''[wiki:RTEMS_Paravirtualization_ Paravirtualization]'' of RTEMS to make it suitable to be run as a guest OS in a hypervisor. * ''[wiki:Projects/SequencedInitialization 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. * ''[wiki:GSoC/2011/ISO9660_Filesystem ISO9660 file system]'' = Debugging = * [wiki:RTEMS_Trace_Tool_ Run-Time Tracing] - includes gathering, capturing, and displaying information to the user. * [wiki:Projects/CPU_Statistics CPU Statistics] - Improvements to CPU Usage Statistics. (SOCIS) * [wiki:Projects/Open/StackChecker Stack Checker] - Improvements to Stack Bounds Checker. (SOCIS) = Board Support Package (BSP) = * RTEMS can always use [wiki:TBR/Delete/MoreBSPsForSimulators more BSPs for Simulators]. Being able to test, debug, and perform coverage analysis on simulators is critical to the ongoing success of the project. * We always welcome new BSPs for useful targets. Of special interest are readily available boards and open cores. * ''[wiki:MMU_Support_ MMU Support]'' Implement MMU low-level support code for more BSPs. = API Layers (POSIX, Classic, SAPI) = * Make rename() implementation POSIX conformant * Implement OSEK Support [http://portal.osek-vdx.org/] * Investigate the feasibility of implementing applicable sections of the [http://en.wikipedia.org/wiki/IEC_61131 IEC 61131] standard to enable RTEMS-enabled hardware to act as a [http://en.wikipedia.org/wiki/Programmable_logic_controller Programmable Logic Controller]. More information on the IEC 61131 standard can be found at http://www.plcopen.org/ .

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 are appropriate for SOC. * ''[wiki:TBR/UserManual/USBStack port BSD USB stack]'' = Languages = * [wiki:Projects/Mono Mono On RTEMS] * Port the [http://code.google.com/p/v8/ Javascript V8 engine] to RTEMS. V8 is high performance JavaScript engine written in C++ and embeddable in C++ applications. With V8 it would be easier to build web servers with javascript and even run js framework node.js. = Libraries and Applications = * Identify and implement the functionality currently missing in dup() * Port Transparent IPC (http://tipc.sourceforge.net/index.html) to RTEMS * Implement a [wiki:Projects/Open/LineEditor Simple Line Editor]. Existing code can be refactored for a starting point. * ''[wiki:Dynamic_Object_File_Loading_ 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. Here are the toolkits areas identified so far: * Define a generic (Waf-based) infrastructure for building and maintaining toolkits. * RTEMS Add ons - [http://git.rtems.org/rtems-addon-packages/ Add on packages] for RTEMS. * [wiki:Projects/BenchmarkKit RTEMS BenchKit] - benchmark programs for RTEMS * [wiki:Projects/ApplicationConfigurationKit RTEMS ConfigKit] - configuration file parsing libraries * [wiki:Projects/DatabaseKit RTEMS DBKit] - database packages * [wiki:Projects/GraphicsToolkit RTEMSGraphicsToolkit] - various graphics and video processing.

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 [wiki:RTEMSHyperVisor_ hypervisor]. The lack of protected (kernel mode) execution precludes any feasible implementations. * Merge [wiki:SimpleScalar_ BSP for Simplescalar simulator]. The BSP is heavily bit-rotted and the simulator is a dead project. * [http://code.google.com/p/rosetta-os Rosetta OS] [[RosettaOSDeviceDriverAPI| 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 [[libbsd-port| NIC device drivers]].
