CPU cores are clocked via an external clock. This clock can be on the board (from a crystal oscillator to complex PLL) or on-chip for some system-on-chip. In all the (current) QEMU MIPS machines it is external although. Regards, Phil.

The others depend of #1 which has been asked for changes. Thanks, Phil.
