Plugin system for the Wii U. (WIP)

I decided to make this entirely public, so everbody can contribute.

Goal

The goal is provide a mechanism to modifiy your Wii U experience in a modular way. Currently each features has it's own application (TCPGecko, SwapDRC, HIDtoVPAD, SDCafiine) and you can only start one applicationa the same time. This means, you can't mix any of these features. One way would be to create an own App for each feature combination (like geckiine) or create one app that has all features. Both approaches have the same disadvantage, it's nearly impossible (and time consuming) to support everthing requested/possible.

The idea is now:

Each feature will be deployed as an individual module/plugin
These modules will be loaded with ONE generic loader
And can be mixed in any way
A GUI can (de)activate them without any new compiling
Everything can be handled easily on the console itself

Planned features

Short-term goals

Possbile to create a plugin which:

can override existing system function
- provide a hook function which will be called
- on each start of an application
- everytime a application will be closed
- on each frame
can be combined with other plugins

With an simple, generic loader which:

Loads the plugins from the SDCard
Combines them and use them ALL at the same time.

General:

Port some currently available tools.

Mid-term goals

General:

Port all common applications like TCPGecko etc.

Loader:

Allow to patch the currently loaded RPX
- This would lead game binaries

More advanced plugin loader:

Create configuration system:
- (de)activate certain plugin only in set applications.
- (de)activate plugins completly without removing them from the SDCard.

Long-term goals

Even more advanced plugin loader:

Downloading plugins directly on the console
Updatin existing plugins
Share configurations with other user
Allow the plugin to have an own configuration window.

Technical problems

To achieve this, serveral "problems" need to be resolved (feature need to be implemented). This is just an short overview. Look at the issued for detailed information.

plugin

Create an stable interface the plugins will use.
- with hooks for
- application start
  - application end
  - each frame
  - functions
- some way to configure them?
Prodivde the plugin as a .elf?
- Keep the file ending?
- Compress/zip it?
How to add meta information?
- Compatibility with
  - Plugin loader
  - Wii U FW
- Information about the plugin
  - Author(s)
  - Version
  - Description
Linking / building
- How to link the files
- Write a proper (base) makefile
- Is position independent code possible?
  - Is it reliable?
- If not, how does elf relocation work?
