Hi Sebastian, Thanks for the clarification. I had one approach in my mind(direct generation of CTF) which seems failed now. Now, how should I convert the trace data into CTF?
I looked into the codebase. I think these are the below files that we have to work with. grep -r rtems/record.h --include='*.[ch]' cpukit/include/rtems/confdefs.h: #include <rtems/record.h> cpukit/libtrace/record/record-server.c:#include <rtems/record.h> cpukit/libtrace/record/record-sysinit.c:#include <rtems/record.h> cpukit/libtrace/record/record.c:#include <rtems/record.h> cpukit/libtrace/record/record-userext.c:#include <rtems/record.h> 5/arm-rtems5/xilinx_zynq_a9_qemu/lib/include/rtems/confdefs.h: #include <rtems/record.h> Thanks On Thu, May 16, 2019 at 12:14 PM Sebastian Huber < sebastian.hu...@embedded-brains.de> wrote: > On 15/05/2019 18:45, Ravindra Kumar Meena wrote: > > > > On Wed, May 15, 2019 at 5:27 PM Sebastian Huber > > <sebastian.hu...@embedded-brains.de > > <mailto:sebastian.hu...@embedded-brains.de>> wrote: > > > > On 15/05/2019 13:50, Ravindra Kumar Meena wrote: > > > > Is lttng under a suitable license (I think no) and portable to RTEMS? > > > > I found this at the bottom of LTTng website. https://lttng.org/ > > > > " The LTTng Documentation is licensed under CC BY 4.0.
