Failed to build the drivers

[yuzhang3_intel]

Could you provide the platform and VTune release information? BTW, the public 2024.1 is released, please try with the latest version, thanks.

[MickeJ-IUA]

Thank you. I am using Linux.

I download "sepdk.tar.gz" from the Intel Webpage Intel® VTune™ Profiler Sampling Driver Downloads

This documentation page with ID nr 657847 states it was updated 1/23/2024

Tell me if this driver download link is correct.

[yuzhang3_intel]

After you install VTune Profiler, the driver source is there as below, you can build the source, don't need to download from web page.

/opt/intel/oneapi/vtune/latest/sepdk

Following the steps in the link to build your driver.

https://www.intel.com/content/www/us/en/docs/vtune-profiler/user-guide/2024-0/build-install-sampling-drivers-for-linux-targets.html#GUID-CC4C2F86-21A6-402A-97B0-3DA1FFD2C8F4

[MickeJ-IUA]

Thank you. The documentation page you refer to has a note:

NOTE:

If the current version of the sampling driver that is shipped with the VTune Profiler installation does not suit your needs, for example, due to a recent change in the Linux* kernel, you can find the latest version of the sampling driver on the Sampling Driver Downloads page.

When compilation failed i followed the note in the installation documentation you referred to. quote "you can find the latest version of the sampling driver on the Sampling Driver Downloads page." If the latest version is not there you need to correct the documentation.

After upgrading and testing again building one of the drivers failed.

ERROR: Failed to build socwatch2_15-x32_64-6.8.2-1420.nativesmp.ko driver

I post the complete build log in the attached txt file.

[yuzhang3_intel · Accepted solution]

A similar issue was reported in the forum, we are investigating now. VTune should work if you don't care about power metrics. SoCWatch driver is for power measurement.

[MickeJ-IUA]

Ok 

i will proceed without the power measurement driver

Thank you
