My test setup is a dual Xeon IBM intellistation with fc6 and 2.6.18-rt7 #1 SMP PREEMPT. Running the last systemtap snapshot I get the results === systemtap Summary === # of expected passes 147 # of unexpected failures 4 # of expected failures 116 # of unknown successes 2 # of known failures 3 # of untested testcases 74 The the tcp test fails because the symbol HRTIMER_REL cannot be found. detail for the tcp tests is. /home/sperryd/kernels/systap18rt7/src/testsuite/buildok/tcp_test.stp -vvvv probe_1509 probe_1511 probe_1512 enter_kprobe_probe enter_kretprobe_probe enter_hrtimer_probe systemtap_module_init /tmp/stapc3sTb9/stap_638ce45d23c34f17540fb6c3ee1929a7_3720.c: In function 'systemtap_module_init': /tmp/stapc3sTb9/stap_638ce45d23c34f17540fb6c3ee1929a7_3720.c:1544: error: 'HRTIMER_REL' undeclared (first use in this function) /tmp/stapc3sTb9/stap_638ce45d23c34f17540fb6c3ee1929a7_3720.c:1544: error: (Each undeclared identifier is reported only once /tmp/stapc3sTb9/stap_638ce45d23c34f17540fb6c3ee1929a7_3720.c:1544: error: for each function it appears in.) cc1: warnings being treated as errors /tmp/stapc3sTb9/stap_638ce45d23c34f17540fb6c3ee1929a7_3720.c:1545: warning: assignment from incompatible pointer type systemtap_module_exit probe_start probe_exit __check_send_bytes __check_recv_bytes __check_ports __check_rtos __check_state __check_mss __check_ssthresh __check_cwnd Is there a way to make systemtap RT aware?
