Couldnt a basic bootloader with this valid DRM signature be used to chain load a new linux kernel into the PS3? The DRM is hardware based I take it?

Why would they do that. Would defeat their reason for adding DRM to hardware

DRM? Digital rights management?

You could call running only signed binaries DRM...

Here's the thing, Yellow Dog Linux will most likely be unable to play PS3 games because PS3 games can most likely only be launched from the PS3's OS. I think any protection from games being played illegally is placed elsewhere than in a 3rd party product.

The issue of games being ripped via Linux isn't that big, I mean, look at every damn console today, you can't prevent that from happening anyway.

Again, my question is, while Sony could probably restrict kernel choices, why the hell would they want to?

Yes but what's preventing execution of a PS3 game from Linux?

The same thing that prevents me from running lots of Windows games under Linux.

Duh.

Games don't magically execute on operating systems they're not made for. No programs do. Maybe if they include a Java runtime environment and all the PS3 games are written in Java, but you know, that sounds unlikely.

A Windows game won't run under Linux because it needs Windows. A PS3 game presumably only needs the hardware so you'd make the Linux unload itself except for a minimal loader and use that to launch the iso.

I'm going to guess launching PS3 games is a bit more complicated than that. Sony's not stupid.

You need to go through the Playstation 3's bios and copy protection in any case, that's probably what a minimal loader would do, not that Sony would make one of those. That has no relation to the Linux kernel though.

Why does Sony Updates to PSP prevent u from installing your own apps on it ?
Not like u gonna get your hands on a UMD burner & copy games or go through hassle of a USB Memory Card to hold the games.

They like to control the hardware simply put
Really annoyed me having Wireless on a PSP and unable to play a video or avi over it. Let alone anything else thats complicated unless u build a web interface for it

How does that have any relation whatsoever to the topic?

And of course they like control of their money. Isn't that, you know, obvious and something every company wants? They can't control their money without controlling the amount of piracy, which can't be done without controlling the hardware.

Basic logic, really. You'd do the same in Sony's place.

I saying there was no reason for Sony PSP to disable installing your own apps to make PSP more usefull.

This is same company in regards developing PS3, their gonna todo the same.
And there is already DRM in the PS3, so u can bet thier gonna required a signed kernel to load up Linux. Not to mention PSP will feature as a controller for the PS3.

So it is related to topic.
Pointing out how Sony limited hardware (PSP in this case) to what they intend it to do. And thus its related to this topic.

Also how where peep gonna piracy with a altered PSP.
How where u gonna get your hands on a UMD Burner. Or go through hassle of uploading all of it to a USB Memory Card, that doesnt come cheap & alot of hassle to switch games on Memory Card around == putting User off the idea.

Putting users off the idea doesn't mean the idea is impossible though, and if it's possible, and for free games at that, it's a very likely loss for Sony. Which is why they would have to restrict it.

There is. More control. To avoid piracy. To get money.

Link a reliable article that says anything about the PS3's DRM. Why would they require a signed kernel in Linux? They would require the disc to be use their copy protection, sure, otherwise it wouldn't boot in the first place. but what relation that has to the kernel confuses me. Very much.

Liunux is NOT the PS3 OS. the PS3 is ABLE to use Linux as an OS.

PS3 games are however launched throught he prorietary Playstation OS. wich has nothign to do with linux., or it might, but it has nothign to do with whatever other linux you can run on the PS3.

I think everyone here knows that, as the article linked to basically says that.

Or maybe people here suck at reading comprehension. I don't really know, judging from the replies.

Yes but if the Linux was uncrippled it could be used instead of the PS3's own firmware to act as a bootloader for isos.

you still wouldn't be able to open PS3 games thoguh such a bios.

and other games designed for linux shoudl work fine with or without their crippled kernel.

Why not? You'd just need a way to inject the code into the system itself somehow and I don't think that's too difficult if you can replace the kernel with your own.

Didn't they hack the XBOX360 by replacing the DVD drive's rom with an emulator? I guess it's possible on the PS3 but more difficult.

You'd still have to run it through the PS3 bios and so the PS3's copy protection though. So being able to run games from Linux (but you really wouldn't be, as you would be running the PS3's OS after you've launched the game) wouldn't make piracy any easier.

So, my question is still the same, why the hell would Sony restrict what kernel you use?

But seeing hollowsoul was the first who mentioned that and he didn't seem to know exactly what he was talking about, maybe we should forget discussing the kernel and DRM.
