From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050720 Fedora/1.0.6-1.1.fc4 Firefox/1.0.6 Description of problem: It would be very useful if the Fedora xen kernels worked with kprobes. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Download devel xen kernel 2. Verify kprobes not configured 3. Additional info:
kprobes is on in our current rawhide kernel-xen config. But systemtap is broken in other ways (it fails to compile the stap scripts due to a #warning in <linux/config.h>). It's apparently fixed in upstream systemtap CVS, so when the fix propagates to rawhide I'll be able to test if it's actually working.
I got a direct kprobes test case from fche; all works fine on a Xen domU.
