Hi ,All
I got some problem about the jiffies in linux2.6.13.2
in linux 2.6 , jiffies.h is added to <kernel_path>/include/linux for jiffies definition,
and I found the jiffies is set to -300*HZ as its initial value--> why??
furthermore, I found a new varaible jiffies_64 is added,
I see jiffies_u64++ in do_timer() (HW timer ISR), but see NO jiffies++ in do_timer(), just as the case in linux2.4?
Why?
what relationship between jiffies and jiffies_64?
