[Cbe-oss-dev] PS3 performance analysis - errors on loading cellperfctr module

[Dimitar Lukarski]

Hello,

    I am try to get some performance analysis on PS3 running under 
Yellow Dog Linux 5.0 and IBM SDK 2.1.
    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.

    Is it problem with my kernel compilation or just PS3 does not 
support SPU sampling ?

 
# modprobe cellperfctr
FATAL: Error inserting cellperfctr 
(/lib/modules/2.6.23custom/extra/cellperfctr.ko): Unknown symbol in 
module, or unknown parameter (see dmesg)


# dmesg | tail
cellperfctr: Unknown symbol cbe_read_pm07_control
cellperfctr: Unknown symbol cbe_read_pm
cellperfctr: Unknown symbol cbe_write_pm07_control

cellperfctr: Unknown symbol cbe_write_phys_ctr
