Over the weekend, the folks at PS2Dev.org (linked above) have began a collaborative development effort in hopes of finally getting a freeware (non-Sony) legal PS3SDK rolling similar to the popular [Register or Login to view links] project.
To quote mc: Well, we've all heard the rumors about ongoing PS3SDK development efforts, but so far nobody has shown any code.
I think the main problem with getting a PS3SDK out the door is that it's a rather large project for one or two persons to undertake, so eventually anyone who tries on his own will get stuck and/or fed up.
So what I'd like to do is invite to a collaborative effort, and the correct way to do this is of course to present all the code I have so far, and allow people to start expanding it.
What I have currently is a small multithreading kernel (supports use of both HW threads), integration with newlib, and some simple GPU support.
There are plenty of work packages for interested parties to get down with, including (but not limited to)
- Interrupt handling
- A more sophisticated MMU driver
- USB (the driver in mcload can't be used as it contains GPL code)
- Storage drivers and filesystems
- SPE support
- VMX support (currently context switching does not preserve vector registers)
To get going, check out the following bzr repository:
Note that you will need to rebuild newlib with the patch contained in the "misc" directory (simply copy the patch over the old one in the ps3toolchain distribution).
If you want to start working on something, please let me know, and preferably publish the URL of your own bzr branch, so that others can follow your progress, and so that I can merge things back to my main branch.
