Intel® VTune™ Amplifier uses kernel drivers to enable the hardware event-based sampling and power analysis on Linux* OS. VTune Amplifier installer automatically uses the Sampling Driver Kit and the Power Driver Kit to build a driver for your kernel. If you are not using a default kernel on the supported Linux* distributions listed in the Release Notes, use these Driver Kits to compile drivers for your kernel manually.
Note
If the driver was not properly installed or unavailable for the current system, the VTune Amplifier cannot run hardware event-based sampling or power analysis types and displays an error message.
You may need kernel header sources and other additional software to build and load the kernel drivers on Linux. For details, see the
README.txtfiles in thesepdk/srcandpowerdk/srcdirectories.
To build the drivers, choose the Change advanced options item during installation. VTune Amplifier provides the following advanced options:
Use This Option | To Do This |
|---|---|
Sampling driver install type [build driver (default) / driver kit files only ] Power driver install type [build driver (default) / driver kit files only ] | Choose the driver installation option. By default, VTune Amplifier uses the Sampling/Power Driver Kit to build the driver for your kernel. You may change the option to driver kit files only if you want to build the driver manually after installation. |
Driver access group [ vtune (default) ] | Set the driver access group ownership to determine which set of users can perform the collection on the system. By default, the group is By default, |
Driver permissions [ 660 (default) ] | Change permissions for the driver. |
Load driver [ yes (default) ] | Load the driver into the kernel. |
Install boot script [ yes (default) ] | Use a boot script that loads the driver into the kernel each time the system is rebooted. The boot script can be disabled later by executing: |
Enable per-user collection mode [no (default) / yes] | Install the hardware event-based collector driver with the per-user filtering on. When the filtering is on, the collector gathers data only for the processes spawned by the user who started the collection. When it is off (default), samples from all processes on the system are collected. Consider using the filtering to isolate the collection from other users on a cluster for security reasons. The administrator/root can change the filtering mode by rebuilding/restarting the driver at any time. A regular user cannot change the mode after the product is installed. |
Driver build options … | Specify the location of the kernel header files on this system, the path and name of the C compiler to use for building the driver, the path and name of the make command to use for building the driver. |
