I read that there's no 3d acceleration at this time.

It's still being worked on heavily.

As promised, Sony opens up PS3. This really adds value to the console and is great advantage over main competitor's offerings (MS & nintendo).

Graphic card is essentialy a G70 variant. I hope that nvidia will release a binary driver for Cell soon (Sony might give a blessing). If not, maybe that void will be filled by the nouveau driver.

Since Linux runs on a Hypervisor inside the PS3, i have the following question.
Can the hypervisor be used to abstract the Graphic Card, and provide some APIs for the 3d acceleration?
Can the hypervisor be user to limit the use of the BD-ROM.(forbid reading the BD disks from linux?)

Wait... It runs under virtualization? Can you provide a link for that info?

LinuxKernelOverview.html


Linux kernel can access some devices directly (e.g. USB host controller). Other devices are virtualized by hypervisor and device service is provided via hypervisor call. For example, storage service hypervisor calls are available. See following sections for detail.

As I see it, limiting use of 3d is basically a way for Sony/IBM to have the cake and eat it in the same time.

1. they can trump added value of PS3 besides gaming by enabling linux compatibility, for use in utility/non gaming software. It will fully expose cell but limit access to GPU/BDA.
2. they can grow cell developers/researchers community, (esp. in academia) which is essenctial for the architecture's further acceptance
3. they still can offset the subsidized PS3 price by providing proprietary (read expensive) gaming SDK under NDA which allows access to full GPU power.

Does anyone know if the RAM is upgradable? With 1GB many things can be done!!!!

I doubt that. IBM sells cell based blades for a small fortune for "serious things".

Yeah I'll give you a little reminder, could it be becuase Microsoft also makes Windows? I don't think they would encourage people to install Linux on their console.

>Can someone remind me why Microsoft went to such considerable lengths to prevent anyone running Linux on the 360?

They didn't do anything specific to block Linux. They blocked everything to get rid of pirated games.

They went with YellowDog since YellowDog is an all PowerPC distro. Which the Cell chip is similar to I guess.

Or maybe Yellow Dog went to Sony because Apple basicly destroyed their bussiness.

and both YD and sony are rooted in Japan.

Your guess makes some sense as compared to others.
Good!

YellowDog was the expert on getting Linux running on Power based processors back in the day. Remember all the YellowDog PowerPC releases? I think Cell is similar in design to the Power chip but I could be wrong?

My first encounter with PowerPC was with SUSE Linux on an IBM server machine. It was long after, that I ever heard of YDL. And now, with the kind help of Genesi, it's Gentoo Linux, which first supports PS3 with freely available downloads. Of course, the first thing I'll do when I can put my hands on a PS3 is to port SUSE Linux to it :-) It's a shame, that it arrived too late to have official support for it in openSUSE 10.2...

YellowDog are basically an enhanced ppc version of Fedora Core. In fact, Fedora Core 5 was used as software development kit (SDK) on the Cell architecture with these documentation from IBM themselves:
http://www-128.ibm.com/developerworks/power/library/pa-cellstartsim...

Given their advanced skill with the Fedora Core on ppc architecture and the fact YellowDog was the team behind the existence of YUM, a package manager for both Fedora Core and YellowDog, it was natural for them to choose the former.

Are you sure ?

I thought YellowDog was "already" around before Fedora ?

Is it then maybe RedHat based ?

EDIT :

"Terra Soft is a small, privately held company in Loveland, Colorado. The company was formed in 1999, and initially focused on offering Yellow Dog Linux .. ."

& 1999 is way before Fedora ... okay later in the article it says "based on Fedora" - but then they must have changed to Fedora - or well "changed" from RedHat to Fedora .

Red Hat Linux to be specific. When the former was no longer in production, Terrasoft switched to Fedora Core as base distribution. You have answered to you own question when you have edited your post.

well it's not quite gaming on linux but it is most certainly gaming and linux

So is an Xbox (1). Or a standard dual-boot PC, for that matter.

If this works well this will be the cheapest high end gaming computer availible at 600.

Or you could get an Xbox 360 ($299) for gaming and a cheap Linux PC ($199 or, if second-hand, essentially free), both of which perform their tasks more ably than the PS3 does.

"Sure, but why?"

So that you can't rip a blu-ray disc to the hard drive probably.

I'm not saying that Blu-ray reading will be blocked. I think the docs indicate that it won't be. But if it was, then it would be as added copy protection. Probably in case DVD Jon succeeds with his "DeAACS."
