GeoHot Releases Sample PS3 Linux Isolated SPU Loader Code


Sponsored Links
256w ago - Today GeoHot has released sample PS3 Linux isolated SPU loader code for those with OtherOS to experiment with.

To quote: "Right now, I'm playing with the isolated SPEs, trying to get metldr to load from OtherOS. Interesting thing, I am not using the exploit. I always assumed the enable isolation mode register was hypervisor privileged.

It's not, it's kernel privileged, which means using hypervisor calls you can all get to it. So, get to hacking. [Register or Login to view links] is the code I am playing with.

I'm not that opposed to releasing the exploit, but I think the majority of you are going to be disappointed, even if you do get it working. Unless you have pushed the HV to it's limits, this exploit really isn't going to do much for you... yet.

So install OtherOS and start playing around. If people start coming up with convincing reasons why they need the exploit to go further, I'll release it. It's just a waste to release if people can't make use of it.

As far as the GPU goes, I have full access to the GPU memory space 0x2800... But without a driver, it's useless. 3D video card drivers are notoriously hard to write, look at the ATI and NVIDIA ones for linux. The best are still the closed source manufacturer ones.

I'm not even sure I believe that the HV restricts video card access, just that the OtherOS driver is 2D. If someone skilled in video card driver development comes forward, and they can explain in detail what the HV is restricting, I'll send them the exploit."

I encourage everyone to go install OtherOS and play with the hypervisor themselves. If you don't understand what you can't do, you really won't appreciate the new powers the exploit gives you. The PS3 is more open than most of you think apparently.

I would not call this code easy, but much respect to you, man !

It's still being investigated by the Devs... when I know more we'll post on it in the Site News, I imagine sometime tonight.

But for now there is only chitchat going on and that's really annoying since there is no obvious reason for this.

  • Did he just realize that he may not have hacked the system 100%?
  • Is he negotiating with Sony?

I mean... what's the deal? I just don't get it.

he say he is not opposable to release the exploit but in fact, his exploit is not useful for the moment.

maybe something else missing to complete exploit and total access for a fat console.

just wait i think..
