Hello,<br>
<br>
I am try to get some performance analysis on PS3 running under
Yellow Dog Linux 5.0 and IBM SDK 2.1.<br>
I recompile the newest kernel 2.6.23 with oprofile modules. I also
installed cellperfctr-tools-2007.03.19-1.ppc64.rpm plus the modules.
But when I try to load it - it gives errors.<br>
<br>
Is it problem with my kernel compilation or just PS3 does not
support SPU sampling ?<br>
<br>
<br>
# modprobe cellperfctr<br>
FATAL: Error inserting cellperfctr
(/lib/modules/2.6.23custom/extra/cellperfctr.ko): Unknown symbol in
module, or unknown parameter (see dmesg)<br>
<br>
<br>
# dmesg | tail<br>
