Hi all,
systemtap allows instrumenting dynamically kernel functions with the interest of a scripting language that gives access to function parameters or the capability to directly write C code. https://wiki.linaro.org/Platform/DevPlatform/systemtap
I have backported/implemented the support of 2.6.37/2.6.38 kernels in current version of Ubuntu systemtap package (v1.3), which is now uploaded. However, I missed an issue that prevents instrumenting kernel modules on ARM. In fact, I missed it because at work, we are generally probing our drivers (and scheduler/V4L2/...), which are statically linked.
We are then wondering in the group if we can live without the capability to instrument kernel modules with systemtap. Knowing that v1.4, which fixes this issue, has been recently migrated to "Debian tested". And issue and fix are documented on the wiki so you can still recompile the tool ;-)
Therefore, if this capability is critical to you, please speak. Or wait for upgrade to v1.4 !!!!
Regards Fred
