Intel® VTune™ Amplifier uses kernel drivers to enable hardware event-based sampling and collect event-based sampling data from. During the hardware event-based sampling (EBS), also known as analysis in the sampling mode, the Intel® VTune™ Amplifier profiles your. To enable hardware event-based sampling analysis on your platform, the Intel® VTune™ Amplifier uses sampling drivers that require root.

It is available as part of Intel Parallel Studio or as a stand-alone product. Using this access the user can profile the system, an application, or attach to a process.

Alternatively, build the new kernel and flash it to the target device so the target device uses your kernel build.

You may change the option to driver kit files only if you want to build the driver manually after installation.

It is recommended to install the sampling driver for hardware event-based sampling collection types. Guessed Stack Frames Problem: Bandwidth – Platform Power Analysis Window: Summary – Hotspots Window: Cannot Find File Window: VTune Amplifier provides vtume following options:.
