Hello,
Currently I'm using vanilla 2.6.27.35
1. What patch should I use ? There is no patch for 2.6.27.35
2. If I use a patched kernel, can I report events from user space and see
them on a graph ?
Thanks,
Zvika.

Hello,
I'm using ust-0.15.
I ran hello,hello2 contained in tests folder using usttrace.
Then I added the trace to lttv-gui.
Do you have a test code where I can see events or tracepoints on the
graph ?
Till now I managed to see events only in a list at the bottom of the gui.
Thanks,
Zviak.
Hi Zviak,
This is normal. The state system in LTTV only handles kernel traces for
now. When displaying UST traces, the control flow and resource views will
be empty.
There are plans on the mid/long-term roadmap to come up with a generic way
to define "state changes" for UST tracepoints. This will ultimately allow
any application instrumented with UST to display its own resources and
control flow.
