Accessing the GPU (VideoCore IV)

[JxPond]

Is it possible to access the GPU in RISC OS as one can currently do full screen in Raspbian?
to take advantage of the following:

OpenGLES
OpenVG
OpenMAX

VideoCore IV acceleration isn't yet implemented.
If you are a developer, try to port userland librairies from:

http://www.github.com/raspberrypi/userland
(Graphical Acceleration does'nt work in FreeBSD and Plan9 as well)

Wow it is no wonder that Linux seems to be the only OS to support VideoCore IV acceleration on the RPi. Having finaly taken the time to look at that code, it would take a very long time to strip out the OS dependant stuff while keeping it working.

I take it that Broadcom does not like non-Linux OSes?

Probably more likely that there's been no commercial requests for non-Linux support... ?

Yes,

That's right, there is little commercial call for anything other than Linux based (or Windows based) operating systems and therefore no resources to concentrate on that work.

There's nothing wrong with non-linux OSes but it'd be a complete waste of money doing anything with it...

Ok. That is an understandable view. I had not realy thought about that, though Linux does rule the OS world at this time.

The abstraction with the OS is in vcos library.
