Hi, You can also use Kernel Function Trace (which uses tsc or jiffies to measure time) http://tree.celinuxforum.org/pubwiki/moin.cgi/KernelFunctionTrace HTH Regards, Pradeep On 7/1/06, Thomas Petazzoni <thomas.petazzoni@xxxxxxxx> wrote:

Regards, Maybe you can use OProfile, http://oprofile.sourceforge.net/ « OProfile is a system-wide profiler for Linux systems, capable of profiling all running code at low overhead. OProfile is released under the GNU GPL. » From the FAQ: « Can OProfile profile the kernel too ? Yes, it profiles the kernel and all kernel modules by default. Pass the kernel vmlinux image to the post-profiling tools to get kernel profiles (or the module .o files). For example, opreport -l /boot/2.6.0/vmlinux » Sincerly, Thomas -- PETAZZONI Thomas - thomas.petazzoni@xxxxxxxx http://{thomas,sos,kos}.enix.org - Jabber: thomas.petazzoni@xxxxxxxxx http://{agenda,livret}dulibre.org - http://www.toulibre.org Fingerprint : 0BE1 4CF3 CEA4 AC9D CC6E 1624 F653 CB30 98D3 F7A7
