Hi Ralf,
I reviewed the data sheet of Mips CPU - QED RM5231.
There is a wait instruction.
But when the SysAD bus goes to idle, the wait instruction is valid.
How can I SysAD bus make idle state?

Both are PC stuff, so no.

Right now Linux/MIPS will only use the CPU's power managment features, that
is the wait instruction or similar.
