Hi, I am on mips.I am not able to get the kernel traces after following
procedure rightly.I have put the required patches. Cross-compiled the
lttctl and lttv.After doing lttctl -C -w /tmp/trace1 trace1, the trace
starts. Then I stop the trace by lttctl -D trace1. Here untill you press
"Cntrl+C" the trace1 does not stop.


And the output of lttv is like below.


lttv -m textDump -t /tmp/trace1
The input data file /var/tmp/trace1/metadata_0 does not contain a trace
The input data file /var/tmp/trace1/block_0 does not contain a trace
The input data file /var/tmp/trace1/fd_state_0 does not contain a trace
The input data file /var/tmp/trace1/fs_0 does not contain a trace
The input data file /var/tmp/trace1/global_state_0 does not contain a
trace
The input data file /var/tmp/trace1/input_0 does not contain a trace
The input data file /var/tmp/trace1/ipc_0 does not contain a trace
The input data file /var/tmp/trace1/irq_state_0 does not contain a trace

And inside the /tmp/trace1 directory I am able to find the following
files doing
"ls -l"
