thank you
thanks, this is enlightening. perhaps a usb driver? I had this idea to make a "target disk mode" for linux. that would require making a computer behave like a slave type usb device (usb is slave/master pattern protocol right?) Theres documentation for making usb drivers for interfacing with usb devices but I cant find docs for making usb linux devices to serve content via usb.

If you're looking to work on the OpenGL Mesa side of things, the devs have said you mainly need to be very familiar with OpenGL. Create some 3D apps, make sure you understand how that API works, and you should be able to dive right in. Compiler theory and matrix math is probably very helpful background, but if you can create some non-trivial OpenGL apps you probably know enough to work on Mesa.
If you're looking more at enabling features in the hardware, that's more likely to be inside the kernel and is tougher to get started in. You should probably look at a few of the simpler kernel drivers, maybe try submitting a patch or 2 for another driver first, something simpler than graphics. Once you get the hang of kernel development, working with the gpus isn't much different than any other piece of hardware.

That's the turnaround time in doing work behind closed-doors first, then clearing AMD's legal review, publishing of the hardware enablement code and other features, and then repeating the process. Unlike Intel, AMD doesn't publicly work on their next-generation open-source driver support code. They push when it's ready and when the higher-ups tell them that it's okay.Last edited by bridgman; 17 November 2011, 03:48 PM.

its useful because this allows the cpu to use vram as normal ram and the gpu can use the normal ram as vram.
without streaming coping data between spaces.
And CPU access to VRAM is likely not what they had in mind.
Note also that most of marketing about all this is aimed at next generation APU where some of this does make lot more sense.

Fermi

the fermi only do have some features bot not all and not the key features.
the fermi do not have x86 64bit shared ram space.
the fermi do not have the new ram
the fermi is not directX 12.
and so one and so one
And it's Direct3D 11.1, not 12 - and there's not really any great changes there ... well, they added back "logical operations in a render target", which OpenGL had since version 1.1.
