Need suggestions for system wide profiler for an embedded linux device

I would like to profile my embedded linux device for various actions (e.g. touch input on screen, flip a page in a news reading app etc). But the requirement is that the profiler should generate information for the entire software stack on the device开发者_如何学运维 both user space and kernel space. It would be best if the profiler does not include a significant overhead for logging purposes as memory and resources are very limited on the embedded linux device.

Any suggestions ?

Have you tried OProfile?

It supports several hardware architectures and I believe that it is included in the latest mainline kernels. It can also profile both the userspace and the kernel itself.
