Failed to Build Sampling Driver with 5.10.3 kernel on Ubuntu 20.04.2 LTS

Hi,

Good day,

I am having problem compiling Sampling Driver with 5.10.3 kernel:

From some googling, it seems that the api has been deprecated since 5.10.

Thus, is there a newer version of VTune or any workaround for it.

FYI, I am using VTune 2021.1.1.

Thanks,

Vincent

Hi.

Currently there is no public release with 5.10 kernel support.

I'll connect you for workaround directly.

I'm receiving similar errors when compiling the drivers for Vtune under Fedora kernel 5.10.16-200.fc22.x86_64. (Errors pasted below.) Is the work-around available to the public?

Please, just replace VTUNE_INSTALL_DIR/sepdk/src/pax/pax.c file.

It has just fixes for kernel 5.10+ support

Official public release with 5.10 kernel support will be VTune 2021.2.0.

Thanks, Kirill

You rock, Kirill! The replacement pax.c file allowed me to proceed with the build. Many thanks!
