Here’s again a post from one of the graphics professionals, and I want to explain *why* people like Luc and Erik, who actually *work* in the field, are pissed off.

Basically, what you just did is a great thing indeed: It allows developers to port any operating system to the BCM2835 and have working OpenGL ES acceleration there. This is more than any other ARM SoC can offer currently, and you (i.e. Broadcom and the RPi Foundation) certainly deserve credit for that.

The thing that’s not OK is *how* you announced this. This blog posting we now discuss is accurate and well-written, except for one (half) sentence, one you unfortunately chose to stress by writing it in bold face, making it sound like an important statement you’re entitled to be proud of:
“the first ARM-based multimedia SoC with fully-functional, vendor-provided (as opposed to partial, reverse engineered) fully open-source drivers”
See what you did there? “Fully functional”, “fully open source”. You keep saying that. So us graphics guys are starting to become interested: “Hey, they have full driver source code, we can now finally see how that thing is working!” That’s our line of thinking, first because we’re simply interested in how your stuff works, second because this makes us able to learn how to use that hardware most effectively (if you know a GPU’s architecture, you can optimize your code for it), and third because we might eventually also be able to improve it.

But then it turns out that what you released is not a driver at all. Again, let me stress that the “fully open source ARM userland” part is true, only the “driver” one isn’t. I have to say that the basic model of having the VideoCore IV DSP run the OpenGL ES driver including the shader compiler and all the other complicated stuff is indeed elegant. But please, pretty please, stop advertising your API shims as drivers then, because we (that’s Luc, Erik, me, some hundred other people deeply involved with graphics, and I bet even Eben!) know that by far the largest part of the driver is contained inside the firmware blob which, I guess, will not be made open source anytime soon, if ever.
