This is PowerVR again. I think they know they can not get decent support in Linux anyway (binary blobs are required which means it'll not be supported in many cases anyway) and thus stopped supporting Linux altogether.

They plan to ship next generation of Atom (Valley View) with their in-house FOSS-drivers supported GPU and that thing will be supported under Linux.

given that they are the ones who are producing the 'binary blobs', they would be able to either release them, or license them in a way that Linux can deal with.

That's the result of the 'no linux' decision, not the cause of it.

Sorry, but no. You either never developed proprietary software or you pretend to not know how it's done. I doubt PowerVR even gives Intel the whole set of sources (even this will require tens of millions of dollars to exchange hands; most likely they receive source for the "glue code" and bunch of binary files which actually impelement the driver's logic) and the only way for the Intel to provide FOSS source for the thing is to buy Imagination Technologies Group plc.

Which would make absolutely no sense if there are in-house technology ready for the next year.

It's your right to be a Linux zealot and see the conspiracies everywhere, but please don't try to sell your paranoid theories as the facts.

I know for sure that some customers have the whole set of sources. Now, these sources only support one type of window manager, such as SurfaceFlinger in the Android world or X in the Linux one...

This seems the most likely. As someone that was personally involved with getting PowerVR to work with Linux I can attest that it was a pain in the ass. It works, but there's no OpenGL support, no PAE support, no 64 bit support, etc. The windows driver sucks too.

Long live Valley View.

What was your starting point? Reverse engineering or IMG code?

IMG binary driver that we got from Intel. They did most of the integration work and we did the final packaging and testing.

"no PAE support, no 64 bit support"

I'm slightly bewildered as to how these two can arise.

Did you actually have driver source? Surely so long as you control the driver you can ensure that all DMA is 32-bit, all memory mappings are remapped accordingly, and so on?

If you don't have any source, how do you get anything to work with Linux at all?

It was a binary driver. No source code. Unless you used mem=4G on the kernel command line, the machine would boot with a blank screen. We didn't look in to it too much because Intel told us that greater than 4G was required.
