OpenSPARC and Power.org, Who has it Right?

Andy Updegrove writes "Last summer, IBM set up Power.org, to promote its PowerPC chip as what it called 'open hardware.' This year, Sun launched the OpenSPARC.net open source project around the source code for its Niagara microprocessor. But what does 'open' mean in the context of hardware? In the case of Power.org, Juan-Antonio Carballo said, 'It includes but is not limited to open source, where specifications or source code are freely available and can be modified by a community of users. It could also mean that the hardware details can be viewed, but not modified. And it does not necessarily mean that open hardware, or designs that contain it, are free of charge.' True to that statement, you have to pay to participate meaningfully in Power.org, as well as pay royalties to implement - it's built on a traditional RAND consortium model. To use the Sun code, though, its just download the code under an open source license, and you're good to go to use anything except the SPARC name. All of which leads to the questions: What does 'open' mean in hardware, and which approach will work?"

    I don't honestly see what making SPARC or PowerPC "open" is going to achieve at this point.

    SPARC and PowerPC are pretty clearly niche and/or legacy architectures now. IBM has ceded the mainstream desktop to x86, and SPARC lost that battle a long time ago. The only question most people care about now is whether their x86 system is 32 or 64 bit, Intel or VIA or AMD.

    Right now, most open source software tends to be tested and hacked on to at least make it run on PowerPC, for the benefit of Mac users. As the PowerPC Mac users switch to x86, who's going to care about PowerPC compatibility? I remember what it was like running Linux on PowerPC before OS X, and it wasn't pleasant--lots of stuff x86 Linux users took for granted didn't work, or you were stuck with old versions, because nobody had bothered to port, test or debug it.

    SPARC and PowerPC will continue in the high-end server niche, but I think that niche is increasingly going to be squeezed by x86 too. Why deal with the possible risk of having your enterprise application break on PowerPC Linux, or being stuck with old versions of software, when you could run it on a big x86 Linux system and run the same binary 90%+ of the app's users are relying on every day? Sometimes there's safety in numbers.

    PowerPC has the embedded space, of course, and maybe that'll be enough to sustain it as a target for general purpose code. I guess video game toolkits and related libraries will continue to be ported to PowerPC, at least.

    But to go back to "openness"--in the embedded and video games space, who cares if the design is "open" or not? All the PowerPC video game consoles are locked down proprietary systems, as are various other embedded PowerPC systems like TiVo and car computers. And in the high end server space, I don't know that anyone cares there either--System i and System z seem to do OK without having open standard CPUs.

    [Opinions mine, definitely not IBM's, obviously... and I may be completely wrong, perhaps openness is important in those niches?]
