Error Message: Problem Accessing the Sampling Driver
Linux* only error message: Problem accessing the sampling driver. The driver may need to be (re)started.
Intel® VTune™ Profiler cannot access the hardware event-based sampling (EBS) driver required to run a hardware event-based sampling analysis type. This problem happens if the sampling driver was not loaded or you do not have correct permissions.
Make sure the sampling drivers are loaded:
> lsmod | grep sep3_1 or > lsmod | grep sep4_
> lsmod | grep pax
If the drivers are already loaded, make sure you are a member of the vtune user group. You can check the /etc/group file or contact your system administrator to find out if you are a member of this group.
