I think it’s great that you’re doing all this work, but being a complete noob to linux I’m not sure what it all means. I bought my PS3 when they first came out. One of the selling points (for me) was the fact that you could use it as a linux based computer as well. I installed yellow dog about 3 months after getting the PS3 and TBH, haven’t done anything since. I do want to learn how to use Linux (eventually), but don’t want to buy another laptop to do it. I’m totally hacked off with Sony for removing this function.
I’ve never used Torrents, downloaded pirated movies, illegally downloaded any music and I’ve never played a hacked game in my life! I’ve had PS1.PS2 and PS3 and have always appreciated the \backward compatibility\ that has been a feature of Playstation as long as I can remember. I don’t wan’t to get involved in hardware hacks and am not interested in piracy or copyright theft, all I want is my other OS back! Currently I’m sat here on Vers. 3.15 waiting for the PUP file that will give me my Other OS but update the rest of the software. (Apparently the noisy fan will go a lot quieter after the update). In an aside, COD4, Modern warfare tried to update last night but failed to install(something to do with not being the right version OS?perhaps) Now I can’t play the game at all. Not even logging in as another user.
George Hotz said that he’d be releasing a PUP file that would let you keep your Other OS function, but I think he’s been \nobbled\ by Sony not to release it. Is a suitably edited PUP file on the cards at all? Or am I to spend my life with my PS3 guts all over the floor, flashing the hypervisor every time I turn the machine off and rewriting code for every update Sony releases?

It doesn’t bring anything new since the goal of the hack should be to use the Ps3 for other usage then playing game (since it is a gaming console) but nothing is done yet.. We cannot use it as a worstation, cannot use all the core power in Linux and of course cannot play game bypassing the security.

So I don’t know what they are going to do with this “exploit” but all we know is about read and write access on the hypervisor. At least if it was possible to run a homebrew or something.. nothing yet.

titanmkd: check my new post for info on htabs and ptes etc. i dont really see how parsing them will help in anyway however. using the sourcecode in my new post you can dump and parse your own. they dont tell you anything of interest that isn’t already known.

kicko: The blu-ray drives are totally untouched by this exploit. You cannot access anything inside the blu-ray drive via this exploit. And the whole PS3 bd-rom drive using rom-mark stuff is garbage, whoever said the PS3 uses it is pulling the information out of their arse.

I was just wondering.. Since we get access to the Hypervisor, can we get access to the bluray drives’ ram space to mess with the BD ROM-Mark?

Yes it will be a good things to add HTAB / PTE but in a more powerful way
To have full memory mapping from EA -> VA -> Real Addr but it also requires dump of SLB …

There might be some useful info about this here:

Just a wild guess but the flash could be mapped @ 0xA0000000. Could someone with an exploit-ready PS3 try to dump some memory from there?
