Hello all, I'm working on the porting of uClinux 2.6.19 for a new architecture. The system is booting without problems, but I have a problem concerning timekeeping. Indeed, the date command shows that time runs too fast (5 sec in reality for around 10 minutes in Linux...).
So I have read documentation about timekeeping, the important things seems to be the following: - jiffies -> number of timer interrupts (ticks) since the system startup. - xtime.tv_sec -> number of seconds elapsed since Epoch (1970, jan 1 00:00:00) - xtime.tv_nsec -> number of nanoseconds elapsed during the current second. These variables are updated at each timer interrupts, notably in update_wall_time() where xtime fields are modified in an algorithm involving the kernel clock (clocksource). Does this timekeeping mechanism perfectly functionnal for this version of the kernel? I have an other question concerning the macro CLOCK_TICK_RATE (include/asm-'arch-name'/timex.h): this macro seems to be architecture dependant. It's generally 1193180. What is this macro used for? What value should I give to it? Thanks in advance for your help.
