socwatch2_15 module is not loaded correctly when using kernel 6.8.x - vtune/oneapi 2024.1 version

Hi,

I notice this when trying to use VTune 2024.1 version:

[yuzhang3_intel]

Which platform? Kernel version is 6.8.2?

[IonutNechita]

Ubuntu 22.04 OS with kernel 6.8.2 and GCC 11.4.0 using TGL board.

[yuzhang3_intel]

Let me check and update later. If you don't measure power, VTune should work.

[Jennifer_D_Intel]

I can also validate, but I don't believe Linux kernel 6.x is supported yet for VTune.

[IonutNechita]

Hi @Jennifer_D_Intel ,

Ok. Understood. Maybe in feature will be ready for Ubuntu 24.04 LTS.

[zamazan4ik]

Are there public-available plans or something like that about Linux kernel 6.x support for VTune? I also met this limitation. We use 6.x kernels since it consist of useful techs for us.

[Jennifer_D_Intel]

I will follow up with the development team on the current status of kernel 6.x support. It looks like there are some issues with 6.8, but earlier than that should work.

[IonutNechita]

Thank you for this resolution.

Will be wait to have one VTune version with socwatch module correctly inserted in 6.8.x kernel.

Good day.

[Cathy]

Hi,

Is there any update on this? I'm on a similar kernel version and meeting similar issue. I'm on a Meteor Lake Ubuntu 22.04 with kernel 6.8 (have to upgrade kernel to beyond 6.7 to have all stabilized MTL drivers).

thanks

Cathy

[Cathy]

It seems that adding following line near MODULE_IMPORT_NS in socwatch/socwatch_driver/src/sw_driver.c will do the fix.

#ifdef MODULE_IMPORT_NS
MODULE_IMPORT_NS(INTEL_PMT);
MODULE_IMPORT_NS(INTEL_PMT_TELEMETRY);  //add this line
#endif

Hello @Cathy ,

Will try this week to check your change.

But i not have feedback from OneAPI and VTune Team for this issue in this period.

When i check your change, will be write a one note with my feedback.

Thank you Cathy for this.

A good day.

BR,

Ionut

Hello @Cathy ,

I tried today with your change and is working now.
