查看捉虫日记 0004: jiffies stop的源代码

== Analysis ==

Checked the time interrupt and found that the new kernel adopt the clock event strategy and you need to select the CEVT_R4K & CSRC_R4K options and this make the arch/mips/kernel/cevt-r4k.c & csrc-r4k.c can be compiled into kernel.

If you do not select these two options the kernel will use the definiens in include/asm-mips/time.h but this do not have any actually operations. These two functions are mips_clockevent_init() & init_mips_clocksource(). So the system will have no clock interrupt source and then the jiffies would be stop.
