I have a problem with getting traces on kernel 22.214.171.124 with PREEMPT_RT
I can run ltt-armall and create traces by lttctl but when I destroy
traces lttclt hungs.
Is there any fundamental obstacle in RT-kernel for LTT?
I use following versions:
1) kernel 126.96.36.199
2) patch-188.8.131.52-rt13 from
3) LTTng: patch-184.108.40.206-lttng-0.212
4) LTT control: 0.89-05122011
I tuned slightly LTTng patches in order to apply them on rt kernel.
The changes were rather easy and were limited to adaptation of
that had been changed by RT-patch.
I built the kernel (all LTT modules I built in the kernel) successfully.
The problem appears when I try to destroy traces. Lttctl hungs and no
data are copied to files.
Do you have any suggestions?
