Hello there,
I have several questions with regard to oprofile backtracing support in the kernel and would appreciate responses from SUSE Developers.
1. Currently, CONFIG_DEBUG_INFO is not set on openSUSE and SLES9. Will it be set in future SUSE products? This is required for oprofile backtracing to work in user space.
2. Because CONFIG_FRAME_POINTER is not set on openSUSE and SLES9, samples in the kernel will not have backtraces. Is there any possibility that future releases of openSUSE and SLES will have CONFIG_FRAME_POINTER set?
I am currently in the process of developing a front-end with a rewritten oprofile kernel module as the backend. Proper support for backtracing on SUSE products will help customers properly visualize the callstacks.
Check out the kernel-debug kernel. It has above features. Ciao, Marcus
