I have built the 2.6.28-rc4 Linux kernel on an iMac G5 iSight
(g5_defconfig) and installed libpfm3.6. I grabbed the kernel source from
git tree around Nov 21. I have to sneaker-net the git source over to my
platform (no network) so not sure of any updates.
When I run the syst_smp program found in libpfm-3.6/libpfms, I get the
following results:
imacG5 libpfms # ./syst_smp
cpu_t=16 thread=44 session_t=96
ncpus=1 npmds=2
1-way session
monitoring for 10s on all CPUs
CPU0 PMD2 0 PM_CYC
CPU0 PMD4 38779676 PM_INST_CMPL
Also tried the "self" program under examples, and with both programs, I
get PM_CYC count displayed as 0 which doesn't seem right.
Any ideas why? Am I missing something? Are there patches I should apply?
Any help would be appreciated.
