Profiling GPU on Linux 4.14 target

[Tymoshenko__Oleksand]

Hello,

I'm working on a Yocto-based project with Linux kernel 4.14. The hardware platform is Skylake. As far as I understand from documentation VTune Apmplifier requires Media Server Studio installed on target system which also means installing patched 4.4 kernel. Unfortunately, it's not an option. Is it possible to use VTune Amplifier with 4.14? Are there patches or unreleased dev branch for this version? 

Thank you

You have to install the opensource  intel graphics media  sdk  stack from github.

As a starting point, have a look to this project:https://github.com/pauldotknopf/meta-intel-media-stack

That means, libva, media-driver, gmmlib and msdk. You have to apply these patches to the i915 (kernel recipe) for a 4.14 kernel.

• Update SKL DMC FW to v1.27 ( recipe intel firmware)

The latest required patch for yocto has been merged a few days ago, so, follow the master branch for each project.
