PCSX2 Documentation/Contributing To-Do List

Contributing

• Be patient
• Your contribution will gladly be reviewed but free time is an expensive resource
• Discuss your future contribution with us before coding it
• Let's avoid duplicate work! Besides, the specification could be clarified this way.

QA / Portability

• Port GSThread to std::thread => started by krysto
• Port core thread to std::thread
• C11 aligned_alloc
• C++11 alignof/alignas syntax
• Replace volatile/lock-free queue with real C++ atomic
• [C++11 auto port](http://clang.llvm.org/extra/clang-modernize.html). Initial requirement: drop XP and support clang/llvm
• [Clean header include](http://web.archive.org/web/20150419194257/http://code.google.com/p/include-what-you-use/). Investigate.
• Address sanitizer (gcc or clang) and others sanitizer.
• Valgrind (not sure it can run PCSX2, maybe limit the scope to plugin)
• Reformat the core/plugin to a constant style with tool like astyle
• Support Windows/OSX in CMake

GUI

• support wx3.0 => linux port is done but windows part is not ready yet.
• check linux chapter ;) Various improvements are actually cross platform!

Linux

You're welcome to the [Linux contribution thread](http://forums.pcsx2.net/Thread-Areas-of-interest-for-new-linux-developers) to have full details. Here is a handy list of features need implementation. Feel free to propose new ones.

House keeping and general compilation

• Clean up warnings

1. Same as gcc flags but without the need of complete test.

• Clean up GCG flags

1. Put default global flags in cmake/BuildParameters.cmake\\
2. Try to use standard flags as much as possible (aka On). Extensive tests must be done to validate a flag update.

• Support clang (dev build/run without crash) => started by urushima
• Speed comparison clang/GCC
• Support avx (gsdx) => Mostly done. Some compilation errors remain.
• Add missing/update copyright header
• LTO support => started by prudho
• PGO support

Core

• Support XZ compressed ISOs

GSdx

• Fix OpenGL. I would advice to compare dx trace vs OpenGL trace.
• Implement DX features on OGL (video recording ....)
• Test/Fix GLES3.1 (it often breaks after GL update)
• Add tooltip on gsdx gui
• Finish shader subroutine usage (+find a way to clean shader and avoid duplication)
• Finish buffer storage
• OSD => started by myself in a branch feel free to pick it up
• Gameplay recording

CDVD

• Port CDVDgiga to linux ?

zzogl

• Reduce GL requirement to 3.3 + gl4 extension
• Use multibind
• Fix EGL
• Port GLSL to window
• Drop old GLSL backend (and much later Nivida CG)

Debian package

• Needs a refresh to the latest standard
• Clean debian/copyright => debmake -k

Very long term features

Those features will require a lot of work, and an organized long-term effort.

• PS2 ROM reimplementation (wrongly named HLE bios)
• x86_64 port (x32 could yield better perf)
• Android X86 port
• Win/Linux ARM port
• OSX support
