I found that the new kernel (3.18.16) was in the second place in the grub
file. The old kernel was rebooted over the weekend. Now I rebooted the
system with new kernel. It works. Thanks

And rebooting the same kernel?

Thanks all. After rebooting the system, now it works.

Run the following command
$ ./showevtinfo -LED | grep UNC_M_ACT_COUNT
What is the output?

I also used "showevtinfo" program in the example directory to check the
supported PMU. The ivbep_uncore is detected.
Detected PMU models:
[18, ix86arch, "Intel X86 architectural PMU", 7 events, 1 max encoding, 7
counters, core PMU]
[51, perf, "perf_events generic PMU", 80 events, 1 max encoding,
Hi Stephane,
The kernel does support uncore PMU. The directory /sys/devices has all the
uncore information shown below
- uncore_cbox_ {0-9}
- uncore_ha_0
- uncore_imc_{0-3}
- uncore_pcu
- uncore_r2pcie
- uncore_r3qpi_0
- uncore_ubox
Thanks

Hi Stephane,
The following command does not work on my IVB machine:
> sudo ./syst -e IVBEP_UNC_IMC0::UNC_M_ACT_COUNT:RD
syst: event IVBEP_UNC_IMC0::UNC_M_ACT_COUNT:RD: event not found
syst: cannot setup events
My machine is Intel Xeon CPU E5-2660 v2@2.20 (IVB-EP).
Any quick fix?
thanks

Uncore events are ony supported in system-wide mode. You cannot use the
task example for this, use syst_count instead.
I should explain a bit better. Actually, I want to collect the uncore
events, which are shared by all cores in a socket.
For example, the following command works:
sudo ./syst -e UNC_M_ACT_COUNT:RD
But the following two commands do not work
sudo ./syst -e IVBEP_UNC_IMC0:UNC_M_ACT_COUNT:RD
