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

I notice this when trying to use VTune 2024.1 version:

yuzhang3_intel — Thu, 28 Mar 2024 13:16:40 GMT

Which platform? Kernel version is 6.8.2?

IonutNechita — Thu, 28 Mar 2024 13:18:48 GMT

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

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

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

Jennifer_D_Intel — Tue, 09 Apr 2024 06:10:26 GMT

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

IonutNechita — Tue, 09 Apr 2024 10:22:29 GMT

Hi @Jennifer_D_Intel ,

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

zamazan4ik — Wed, 17 Apr 2024 11:26:19 GMT

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 — Tue, 23 Apr 2024 03:19:56 GMT

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 — Tue, 23 Apr 2024 07:43:47 GMT

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.

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 — Fri, 17 May 2024 21:15:29 GMT

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

Was having the same issue for RedHat 9 and this seems to have solved it as well.
