I apologize if this is a duplicate (though I think my earlier message got blocked from the list).

Hi,

This is related to the KNL DAP box which is similar to the JLSE KNL nodes.

Our KNL DAP box, is missing some devices in /sys/devices, in particular it is missing:

/sys/devices/uncore_*

I did some investigation and they seem to be present with an old mpsp CentOS kernel:

3.10.0-327.el7.centos.mpsp_1.3.1.45.x86_64

Otherwise, these devices do not get generated at boot time with default CentOS 7.2 or 7.3 kernel.

Does anyone know what might be going on? I unfortunately, cannot run the mpsp kernel by default due to other issues related to VTune.
