"Last week, Broadcom released the full source of the OpenGL ES 1.1 and 2.0 driver stack for the Broadcom VideoCore IV 3D graphics core, which they provide under a 3-clause BSD license. The VideoCore IV core is used in many of Broadcom's processors, including the BCM2835 chip, which is used in the Raspberry Pi.

But because the release targets the BCM21553 3G cellphone chip, the Raspberry Pi Foundation has announced a bounty of $10,000 to the first person to port it to the BCM2835 chip and successfully run Quake III 'at a resolution of 1920-1080 and a minimum of 20fps, without making use of the capabilities of the blob'. The port, it says, 'should be reasonably straightforward' to accomplish."

    Do we get to see an incredibly unstable rushed-out-the-door-to-make-a-profit port that technically meets the requirements? Or is it sufficiently low a bounty that someone who would work on it anyways says to themselves "Might as well finish, it's a lot of money?"

      The rushed-out-the-door version would still have merit in that the startup effort has been done and one could patch what was there. Of course, if the foundation for the code was so shaky that it really warranted a complete re-write, then you're back to square one, but that would also be true of any version put forward.

      Replying to myself:
      Apparently it can be done, TFA states it should be possible:

      Experienced programmers can:
      Develop fully open drivers for other VideoCore devices, including the Raspberry Pi’s BCM2835 and the BCM21654 (a low-cost 3G integrated baseband for emerging markets).

    I guess if you have to have a metric, that is as good an answer as any other.

    Anybody have any insight as to why Quake III? Why not Doom or Return to Castle Wolfenstein?

      Quake 3 has been open sourced for long enough that the code has been cleaned up a lot and runs on pretty much any architecture. It already runs well on we RPi with the binary blob, so it provides a clean baseline for comparison.

      Thanks for the insight and the frankly kind and informative answers to a question that might have been modded into oblivion at a former hangout of ours.

    Difficulty and potential for 'rushed-out-the-door' scenarios aside, we need more and more of this in the FOSS world. Financial incentives are powerful. Even the most well-meaning, FOSS-philosophy-believing, technical-know-how-having people need money to survive.

      If more people put their money where their mouths are, we'd have a ton of progress in areas that are lacking.

      People are willing to spend thousands on televisions, guitar equipment, and plenty of hobbies. But when it comes to software, everyone thinks it should be free.

      Specialize in what you're good at and outsource the rest. Otherwise, you're just wasting time.

    VideoCore IV is dead commercially. Broadcom blew it in the mobile market, even startups like Vivante overtook them shipping stuff in Chinese fly by night units (Actions, Rockchip) and brand names (Freescale). Broadcom is currently not shipping anything with VideoCore IV.

    Releasing code is a really nice gesture by them, but its 2 years too late. Imagine shipping Rasppi with this documentation.

      Yeah, then instead of being the only thing besides bitcoin I ever saw on /. for months, RaspPi could have... been the only thing besides bitcoin I ever saw on /. for months.

      I have no idea what actual sales numbers were, or how much better you think an open graphics driver would have made them, but they certainly couldn't have had any more hype than they did.

        Sales numbers were in the millions at least (if you're really interested, I can ask - half of the RPi Foundation board works one floor up). It's been enough to annoy a lot of people. ARM's software teams were all ready to declare ARMv6 dead and unsupported and then the RPi took off and now they have a few million consumer devices with people actively wanting to run things on them. FreeBSD's ARMv6 port is actually ARMv7-and-RPi - it won't work on a stock ARMv6 core, it has to be at least an ARM1156 (the RPi has an ARM1176). We'd love to be able to require Thumb-2, since it makes significantly (30-50%) smaller binaries, which given the small i-cache sizes of most ARM cores, makes a noticeable difference, but the RPi doesn't support them so we can't. We're likely to end up shipping packages for ARMv7 and separate ones for the RPi.
