ring support.

 Hi, everyone
As we know, the program on the X86 can run on the differnt ring(0, 1, 2,
 3) and the linux kernel run in the ring 0 and user program in the ring 3.
 And now I want to know wether there is a simple mechanism on the PowerPC
 architecture? thx all!

Powerpc has 2 privilege levels; user and supervisor.  The kernel runs
in supervisor mode, and user-space runs in user mode.

ring on PowerPC

[Bai Shuwei]

Hi, everyone
   As we know, the program on the X86 can run on the differnt ring(0, 1, 2,
3) and the linux kernel run in the ring 0 and user program in the ring 3.
And now I want to know wether there is a simple mechanism on the PowerPC
architecture? thx all!

best regards!

 Powerpc has 2 privilege levels; user and supervisor.  The kernel runs
 in supervisor mode, and user-space runs in user mode.

To be complete here, some implementations have 3 :-) Don't forget
hypervisor mode !
