It’ll be interesting to see what dude: Still nobody is playing those pirated games. The ps3 doesn’t use a global address space and the hypervisor is just using hardware features that are in no way dictated by any code. The x360 hacks are all thanks to the upper 30bit control vector vulnerability and a DMA attack. They do run the browser and most XMB applets in the unprivileged mode from gameos mode and they are all sig checked then decrypted when loaded. It’d take something like a DMA attack to get into secure mode considering they didn’t run the h.a.l in otheros mode/lesser privladged ppc mode while in gameos mode. A heap or stack overflow or any other memory corruption would have -0- effect on the native management code. What this means is a out of bounds security model. The drivers and MMU filter/hypervisor all run on the 7th core and each SPE controls access to it’s local store internally. Hey at least you get a more compact design and a 40nm CBE in the cech2000/slim.
They say it’s because the otheros hypervisor drivers where too expensive to manage. It’s an embedded relatively fast hardware platform to play games at an expected and acceptable performance.
