"According to Phoronix, AMD will be open-sourcing its Linux execution and compiler stack as part of jump-starting the Heterogeneous System Architecture Foundation. The HSA Foundation was started earlier this month at the AMD Fusion Developer Summit and AMD plans to open up its stack so that others can utilize the code without causing HSA fragmentation. This will include LLVM code, the HSA run-time, an HSA kernel driver for Linux distributions, an HSA assembler, and other components."

PS4 rumored to have other OS Linux support and at PS4 release a firmware update to the PS3 will enable Other OS Linux support.

Insiders from Sony say they have introduced a customized kernel version rather than using the basic kernel to support this feature. This customized kernel may support specific versions of Linux only as a part of beta testing. Subsequently Sony will enable all version support after successful completion of beta testing.

But this time Sony is confident that they won’t block this feature, and that they have an alternative to block the security threats.

An inside source also says Sony’s firmware upgrade during the release of PlayStation 4 will re-enable the other OS support in PlayStation 3 as well. So it’s good news for PlayStation 3 owners too after suffering for couple of years. Moreover it’s believed to be a gamble to boost PlayStation 4 sales.

The first part, providing Linux support as Other OS in the PS4 makes sense as it did with the PS3, an effort to expose heterogeneous computing and Cell and with the PS4, to expose AMD's Open Source HSA and OpenCL to as many programmers as possible.

The second part, enabling other OS support for the PS3 would be a marketing (sales) effort or perhaps support for Linux.

Intel is behind Wayland/Westin 1.0 composition layer (using Cairo) instead of Xwindows due in a few months then GTK rewrites to optionally eliminate Xwindows GDK calls. Latest Linux kernel has now absorbed the Google Android Linux kernel changes that didn't use Xwindows (Tim Bird of Sony) and optimized to support embedded lower resource platforms. Latest Linux kernel is now smaller and faster. Rewrite for Glib to use Android D-Buss routines and more to make it faster and smaller. Combine them all and you have a smaller eLinux platform like Tizen or a optimized Gnome Mobile that can also be used for desktop.

In AMD presentations there are references to DRM (Blu-ray) and built-in control points. A special "simpler" Linux kernel could limit features. I don't know how this will play out.



2011 "Cell vision" = AMD HSA IL with Fabric computing memory model (common memory address virtual memory model) and JIT compiler. OS has to support this and a simplified Linux kernel could support this in Software which would provide advanced features that would have many Linux libraries as optional components. PS4 and PS3 getting Linux Other OS support at the same time and Google TV more easily supported by the latest Linux kernel makes me believe the "Cell Vision" will be supported by the Linux OS on the PS3 and PS4. AMD says AMD HSA with HSAIL scales from Handheld to super computer and with a new lighter eLinux that can also scale from handheld to super computer it should open up opportunities. (AMD also appears to be going after handheld to super computer markets).

3D consortium "building block" stacking (IBM, Global Foundries/AMD and Samsung) is going to reduce the cost of SOCs allowing even more powerful AV equipment that can run eLinux OSs.....Sony, Samsung, LG, Google, and others know this and are behind the scenes (Tim Bird of Sony, also Intel and Samsung with Tizen) steering Linux to support new opportunities. (Glib is getting some routines replaced by Android routines. Gstreamer and GTK toolkit require Glib support. Gstreamer 1.0 and Glib rewrites may be why Sony has delayed implementing Commercial DASH and is still using AVM+ for non-commercial DASH)

Multiple technologies discussed in 2008 have been developed over the last 5 years and are to be implemented this year. Nov-Dec 2011 saw published news articles including on the Software side Khronos openMax IL 1.2 which was delayed from 2008 till Nov 2011. h.265 is to be published Jan 2013, Webkit is now nearing full HTML5 <video> and WebGL support with Google-Microsoft-Netflix recently proposing a DRM scheme for HTML5 <video>, Gstreamer 1.0 is now ready for release and Sony used Gstreamer in their Google TV.

Take all the future vision statements we have heard since 2004 and re-look at them as everything is just about in place to support most of them. The long delays seen from 2008 have now been explained....it's starting this year.
