That failure is on this line of kprobe_ftrace.tc: echo _do_fork > set_ftrace_filter This fails because on powerpc the function symbol has a dot prepended to its name: # cat available_filter_functions | grep _do_fork ._do_fork If I do s/_do_fork/._do_fork/ in kprobe_ftrace.tc then all ftrace kprobe tests pass: $ sudo ./ftracetest test.d/kprobe/ === Ftrace unit tests === [1] Kprobe dynamic event - adding and removing [PASS] [2] Kprobe dynamic event - busy event check [PASS] [3] Kprobe dynamic event with arguments [PASS] [4] Kprobe dynamic event with function tracer [PASS] [5] Kretprobe dynamic event with arguments [PASS] # of passed: 5 # of failed: 0 # of unresolved: 0 # of untested: 0 # of unsupported: 0 # of xfailed: 0 # of undefined(test bug): 0 -- []'s Thiago Jung Bauermann IBM Linux Technology Center _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
