"On the PS3, Linux runs under a hypervisor—in essence, PS3 Linux is running on a virtualized machine, similar to a Xen virtualized machine. The hypervisor provides controlled and filtered access to the PS3's hardware. For instance, Linux code has no direct access to the RSX graphics processor. Rather, a special device is provided that allows limited access to it, providing for a reasonably efficient 2D framebuffer."
Ezt meg kellett kerulni.
