Do you mean QEMU itself or Qemu port of the kernel?

It looks timer setting in arch/mips/qemu is somewhat broken.

qemu_timer_setup() installs the timer interrupt handler on irq 0, but
do_qemu_int() also calls ll_timer_interrupt() directly.

Which timer interrupt source does the kernel expect?  r4k counter
interrupt or i8259 timer?
