Hi All,
I am trying to execute LTTng test on MIPS multicore (I pass *numcores=16
while booting)* Octeon based 58xx target board, but the lttv text dump fails
to dump
*My Kernel version: 2.6.32*
*
Linux Trace Toolkit Trace Control 0.78-04122009
Linux Trace Toolkit Visualizer 0.12.29-02022010
*
My questions are
1. Anybody faced this kind of problem ?
2. Is there any patch available for this ? please, can you provide me a
pointer to that patch ?
*-- Thanks and Regards
Naresh Bhat*
