IBM Open Source Firmware Download for PowerPC

Posted by timothy on from the will-we-see-bargains-on-ppc-gear dept.

Nora writes "IBM developerWorks has posted an open source Slimline Open Firmware (SLOF) download intended to aid the development of operating systems and virtualization layers for PowerPC-based machines. One thing that's kind of neat about it is that it is under a pretty liberal "BSD-like" license -- something I have not often seen IBM do. If I am not much mistaken (and please correct me if I am), this license makes it compatible with both GPL'd and BSD'd projects, among others. And in the interest of full disclosure, I'd like to add that I *am* affiliated with the developerWorks site."

      OS X on x86 will not use Open Firmware according to Apple's docs. Presumably they'll use other methods to try to stop it working on any old x86 without some hacking around (some small compatibility problems are probably enough to stop the majority of people running OS X on cheaper PCs).

      However I'm sure IBM have released this to try to bolster the credibility of PowerPC as a platform now that the major desktop vendor is leaving.

      The question is, is there any future in PowerPC on the desktop if Apple is no longer promoting it and IBM are not willing to put a lot of work into developing the chips for desktops/laptops? Their strategy does seem a little schizophrenic, as they promote linux on Power but have antagonized the largest vendor of PPC solutions.

    4. Re:Apple? by TheRaven64 · · Score: 1
      I suspect that OS X86 will run just fine on generic PC systems, but there will be a clause in the license agreement saying this is not allowed. There will also be no copy protection, which will lead to wide-spread piracy. This will help to (unofficially) increase the install base. Once there is a definite demand shown for OS X in other manufacturers hardware, Apple will `reluctantly' agree to license it for use on other systems.

      On Apple's currently selling systems, the profit margin is significantly less that that of a copy of OS X + iLife, and the potential increase in revenue from volume is significant.

      I don't expect Apple to become a pure software company - they will continue to make OS X systems that either fill certain niches, or serve to showcase the abilities of OS X - serious users will continue to want Apple systems, but the more pragmatic will buy other systems (or build their own) and just get OS X from Apple (maybe even an OEM version).

      I respectfully disagree. I think it is relevant, and that developers will put effort into making use of it.

      Think of all the XBoxes running Linux distros currently. The new XBoxes are going to have 3 970 chips in them -- that's a hella-powerful box for $399.

      If I'm not mistaken, the code released by IBM will help developers port OSs for the processor. How long until someone uses it to port Windows or (gasp) OS X to the XBox, among other game consoles and devices using the 970 processor?

      I don't think that the two things (the Apple announcement and the Open Firmware download) are in any way related. To paraphrase an earlier post, I think the timing is too close for it to be anything *more* than coincidence.I could be totally wrong though =)

      But don't forget that one of the largest markets for PowerPC (if not "the" largest) is in embedded -- often deeply embedded. That's an environment where writing your own firmware and/or OS is more relevant -- and one of the reasons it seems particularly smart (to me) to have made the license so liberal.

      Most of the people with access to the full windows source code probably have access to the the full xbox specs as well. Unless you think open firmware is the only thing that's preventing legions of hackers from porting the leaked windows source code to PPC.

      None of the game consoles are using 970s. The processors in the game consoles will have significantly less integer power than the 970, which makes them far less attractive for multitasking, multi-user desktop computing.

      The lead engineer of the Cell project spoke at my university a while back. He pointed out that the flight simulator demo on the cell ran 50 times faster than it did on the 970 where they developed it, but the Cell was somewhat slower than the 970 on integer benchmarks.

      PPC isn't dead, IBM still uses it for their AIX/Linux servers, XBox 360 uses it, the embedded market uses it.

      But really, how many people care if their processor is x86 or not? If it matters, you're probably going to be buying a Sparc or RS and not a macintosh.
