Hello,

Thanks for your question. Let me help to you with the sampling issue. Seems that sampling driver isn't loaded into your kernel.Please try below steps:

1) Load existent pre-built driver:

$ cd /vdk

$ ./insmod-vtune

If there is pre-built driver for your kernel then it will be loaded into the kernel.

2) If there is no pre-built driver for your kernel, you need to build the driver manually. Make sure you have kernel headers configured properly for running kernel.

$ cd /vdk/src

$ ./build-driver

$ ./insmod-vtune

More info can be found in vdk/src/doc/HOWTO-BUILD-VTUNE-DRIVER

Katya
