ERROR - [./src/perfmon.c:623] Counter register MBOX0C0 not supported #99

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.
There is a error when I run "likwid-perfctr  -C 0 -g MEM ls -l".
CPU is Intel Xeon E5-2620.

# likwid-perfctr  -C 0 -g MEM ls -l

-------------------------------------------------------------
CPU type:   Intel Core SandyBridge EP processor 
CPU clock:  2.00 GHz 
Measuring group MEM
ERROR - [./src/perfmon.c:623] Counter register MBOX0C0 not supported

What is the expected output? What do you see instead?
I want to see memory bandwidth.
In another server, it 's work well.

Hi, the current solution for Uncore is a bit fragile as it relies on PCI 
address space registers. And these are relying on proper behaviour of the BIOS 
and the OS kernel to be accessible in a save way. So these devices might be 
missing on your machine, you can check this with lspci  command.

Another reason for your error could be that you did not enable the SandyBridge 
Uncore in config.mk.  The option is called ENABLE_SNB_UNCORE. Default is 
disabled because of the reasons above. Also note that if you enable the Uncore 
the marker API might have a significant overhead on SandyBridge-EP as currently 
all counters are read. This will be resolved in the upcoming release.

Thanks for your help ,maybe some of devices is missing in this server.
How can I know which devices is missing through lspci command ?

I enable SandyBridge Uncore support. 

#likwid-perfctr  -C 0 -g MEM ls -l
INFO
       This system has no support for PCI based Uncore counters.
       This means you cannot use performance groups as MEM, which require Uncore counters.

ERROR
failed to open pci device: No such file or directory!

Hi,

your system is missing the Performance Monitoring PCI devices. See the attached 
file for an example (relevant are the devices starting with 7f and ff). To fix 
that you might need to enable performance monitoring in the BIOS or use a more 
recent kernel (still I do not know exactly since what kernel version those SNB 
devices are supported, our system used a 3.0.51 kernel). It might be necessary 
to update the BIOS (this depends on your mainboard vendor).
