- Configure Yocto Project*/Wind River* Linux* and Intel® VTune™ Profiler with the Intel System Studio Integration Layer
Set Up Remote Linux* Target
Use the Intel® VTune™ Profiler installed on the Windows*, Linux*, or macOS* host to analyze code performance on remote Linux systems.
VTune Profiler supports the following usage modes for remote analysis of Linux applications on regular and embedded systems:
Remote CLI (vtune) or GUI (vtune-gui) (recommended for regular and embedded systems)
Native CLI with installing and running vtune directly on a remote Linux system
Native SEP with sep (recommended for tiny embedded systems)
Remote CLI and GUI Usage Mode
Requirements for the target system: ~25 MB disk space
This mode is recommended for most cross-development scenarios supported by the VTune Profiler, especially if your target system is resource-constrained (insufficient disk space, memory, or CPU power) or if you use a highly customized Linux target system.
To collect data on a remote Linux system:
1. Install VTune Profiler
Install the full-scale VTune Profiler product on the host system.
3. Configure and run remote analysis
VTune Profiler launches your application on the target, collects data, copies the analysis result and binary files to the host, and finalizes the data.
4. View results
View the collected data on the host.
Native Usage Mode
Requirements for the target system: ~200 MB disk space.
This mode is recommended for regular Linux target systems from supported operating systems listed in the product Release Notes. In this mode, you install the full-scale VTune Profiler product on the host system and install the command line interface of the VTune Profiler, vtune, on the target system, which enables you to run native data collection directly on the target.
The following figure shows an overview of the remote analysis that is run with vtune directly on the target system:
In the native usage mode, workflow steps to configure and run analysis on a remote system are similar to the remote collectors mode.
Native Sampling Collector (SEP) Usage Mode
Sampling сollector (SEP) is a command-line tool for hardware event-based sampling analysis targeted for resource-restricted systems. The SEP package is delivered as part of the target package of the VTune Profiler. The SEP package contains both sep utilities and the sepdk source code (for pax.ko and sep4_x.ko) to build the sampling drivers.
To use SEP, extract the SEP package from the vtune_profiler_target_sep_x86.tgz or vtune_profiler_target_sep_x86_64.tgz file, build the driver and upload both driver and sep utilities to the target, and then collect the event-based sampling performance data in command line. See the Sampling Enabling Product User's Guide for more details.
VTune Profiler also provides the sepdk sources for building sampling drivers. This source code could be same as the source code provided in the SEP package, if the VTune Profiler uses the same driver as SEP. VTune Profilersepdk sources also include the event-based stack sampling data collector that is not part of the SEP package.
