Given that the PS3 GPU is similar to other NVIDIA GPUs, would the NOVEAU effort for PC NVIDIA GPUs help here?

Now that we can dump the hypervisor and reverse engineer it, does that mean we can search the undocumented HV calls for the (rumored to exist) GPU setup calls we need for full GPU access?

More than likely, they don't want anyone writing 3D games on the OtherOS since everyone who uses the OtherOS for gaming is one less person who buys proper PS3 games that earn Sony money (remember that the PS3 is sold at a loss and the profits come from the sales of games and blu-ray movies)

What is the state of play with regards to RSX?

Whats going on with the RSX? Have people abandoned all hope of getting hardware acceleration on current PSX firmware? (e.g. people have discovered that there is no way to get at the needed memory locations via current HV) Are people still reverse engineering the PS3 HV to find out if there are HV ca...

Does this patch tell the kernel/HV hackers anything about the Hypervisor that wasnt previously known?

What does AVCHD have to do with BD-J?
I doubt Sony have (or plan) to do anything to stop the AVCHD video codec from working (including working from a USB camcorder). They do seem to be stopping BD-J apps from running via USB mass storage devices though.

I dont think Sony is dropping AVCHD at all, what they HAVE done is stopped all BD-J code from running except code coming from a legit authenticated Blu-Ray disk. As for Sony, by pulling this kind of crap, have ensured that I (and likely others) will NOT buy anything made by Sony. The last Sony produ...

Why would you need to hack the PS3 when you can just use the official OtherOS mode to run your code?

SDL3D isn't a layer on top of OpenGL, its a wrapper for the various os-specific parts of OpenGL such as Wgl* and similar on other platforms and for the other OS specific parts required to set up a window for OpenGL to render to.

From what I have seen on PS3, I see no technical reason preventing Sony and NVIDIA from releasing a closed source RSX binary driver as a binary blob (ala the binary driver for PCs) There may be other reasons (legal, political, internal, tech support) why that cant happen though (including the fears ...

RSX questions

1.Can someone tell me (or direct me to a guide) that discusses the different regions of memory/IO that the RSX exposes?
2.Can someone tell me which regions the RSX hack (that 2.10 seems to remove access to) is accessing?

I think if Sony and NVIDIA provided a binary blob for the PS3 GPU (same sort of thing as what you get for PC NVIDIA GPUs), most of the reasons for needing to hack the PS3 go away and the only reason to even consider hacking GameOS, game data files, executables or anything else outside of OtherOS wou...

From reading the second life wiki, the only binary libraries that matter are: 1.FMOD (can replace with other sound libraries and other audio format decoders such as FFMPEG) 2.QuickTime (can replace with other audio/video format decoders such as FFMPEG) The only other binary libraries listed are CG (...

My understanding is that the DMCA only applies to copy protected works (and to software for playing those works).

Is there any reason why an OpenGL driver could not be written even without Sony? Although I guess if it was that simple, the Nouveau people would have done it for PC NV GPUs by now :)

PS3 GPU questions

1.How much access does linux/otheros have to the GPU? (i.e. are there any GPU features which is it known not to be possible to access) 2.Has Sony done anything to block access to the GPU (i.e. firmware updates that close access to certain GPU registers etc) 3.Does anyone know if, for licensed games ...
