I am trying to perform2 on a MIPS 24k board.
I have successfully built libpfm3-9 and pfmon3-9.
Installed the kernel patch (perfmon-new-base-090622).
While running pfmon I am getting the following message:
# pfmon
Algorithmics/MIPS FPU Emulator v1.5
no detected PMU support type=65
any clue ?

Hi Fabio,
I did some of the MIPS support along with Vince Weaver... You may want to check
the initialization code in mips/perfmon.c.. It's not be detecting your PMU
properly...

Hi,
I don't know much about MIPS perfmon support. But, as Phil suggested, I would
first check that the kernel actually recognized your hardware. Make sure you
have the MIPS PMU module loaded (or compiled in). You can verify by looking
at /sys/kernel/perfmon/model. Alternatively, use dmesg to see i
Thanks for the feedback.
At boot time the kernel reports:
MIPS24K PMU installed
however I can't see /sys/kernel/perfmon/model .
# ls /sys/kernel/perfmon/*

Ok, that was pmu_desc/model.
So you have it, then it must be something wrong in the user code
and in particu
All versions of these cores can be synthesized without the PMU. There
should be code in there that inspects the register that says how many
PMD's are architected... Perhaps that's returning 0?

Thanks again. I will look into probably by beginning of next week and
let you the outcomes.

Peter,
Was the AMD Northbridge patch ever applied to tip?
I don't see it in 2.6.33-rc8-tip+.

The problem is that the pfmon utility itself doesn't have support for the
24k CPU (see pfmon/pfmon_mips64.c)
What you can do is in pfmon/pfmon_mips64.c, cut and paste the
20kc code, then change the occurances of 20kc to 24k.
Then in pfmon/pfmon.c find the code block
#ifdef CONFIG_PFMON_MIPS64
