Thanks Stringer. The problem was built-in module loaded every time instead
of the newly installed.
Now I've another issue. As i'm trying to get the CPU time, but it seems
time.h doesn't work. I tried clock(), clock_gettime() but both of them
don't work is there any other way to find the cpu time?
Module load is governed by depmod, see depmod.d (5) man pages.
To investigate:
# find /lib/modules -name openvswitch.ko
# modinfo openvswitch
You'll see what OVS modules are available and which one is being
selected by default at the moment.

Hi Danish,
Instead of "make module_install", try to load with insmod command. One
more thing, i think by default kernel comes with openvswith.ko in
/lib/moduels/. Check where your module is copied when you did make
modules_install.

I'm just trying to print the following statement to the kernel log.
File: openvswitch\datapath\datapath.c
void ovs_dp_process_packet()
*pr_debug("pr_info inside ovs_dp_process_packet");*
*printk(KERN_DEBUG "printk inside ovs_dp_process_packet");*
*My install script*
* ./boot.sh*
* ./conf
i'm using vmware for the testing. So i have a state saved before compiling
the source code for virtual machine. Each after doing all the modification,
i compile, install and load the module. send some traffic between couple of
hosts then see all the log like kernel, dmesg, syslog etc, if nothing wo
Hi Danish,
Please post four changes. I guess all packets receives via
netdev_frame_hook() function in openvswith.ko module.

Are you sure that you loaded your newly compiled kernel module?
(insmod build_dir/datapath/linux/openvswitch.ko)

I've tried in datapath.c, bridge.c, learning-switch.c and flow-table.c but
nothing works.
For kernel module i'm using printk() to print the messages and for
userspace simply writing to a file but for some reason nothing happens in
either modules.
Any other ideas that i can try to get the openvswit

Hi,
I'm trying to find out the time a packet spends in the switch only. Time
difference between packet in and out.
I thought analyzing the time in learning-switch.c would be give me some
info but that didn't work.
Please help me find the time a packet spends in the switch.
Thanks
*Best Regards*
