As far as I know jiffie counter is incremented HZ times/second. And it is
used to measure the time lapses in the kernel code.
I m seeing a case where, actualy time spent in some module using giffies
On the Sylicon Valey Linux User Group at the Kernel Walktrought (you can
watch it on youtube) Jim said something about kernel remembering its root
devide durring compilation soo when you don't use root arg it will use that
setting inside of its image. But someone might verify this

how about to check the disable/enable timer interrupt?
cat /proc/stat before/after 2 seconds?

hi:
I am debuging kernel with gdb , when it comes into a page_fault exception
,how
to get to know how does that address come out ?
It is the same to ask : which code is using that address , causing the
page_fault exception?
thanks!

Hi All
I am seeing this problem at the very early in the start_kernel--
mm_init-- free_highpages, at that time nothing is up and kernel is running
in single thread.
Thanks

If you build a kernel with printk timestamps, you'll see that they all
come out
Dear Anish, Mulyadi,
this is how i read jiffies.
unsigned long start_time, end_time;
start_time = jiffies;
free_area(***);
end_time = jiffies;
printk(%ld, end_time-start_time);
I onserved jiffies getting incremented at different place, though
thanks

Hi Mr.Valdis
as you rightly mentioned,cat /proc/kmsg is showing the time stamps,
according to that it is 0ms only.
But when you see the same with UART there is 2sec delay in showing the next
log. i caught this while i m observing the UART logs with
Terminaliranicca.
Since i m early in the

Hi Valdis,
Device specs: CPU: 1.7Ghz RAM: 2GB.
We are not adding any code in the mm_init, All we do is reserve some memory
during the boot time and rest of the memory around 1.45GB we configure it
as HIGHMEM.
Can you give me any info on how to do the profiling of the function calls
during ealry
