OneAPI beta03 VTune vtsspp driver failed to be loaded

[Tse__Amon]

Hello,

During installation of OneAPI beta03 on Ubuntu 18.04, I encountered the failure of loading of vtsspp driver.

I attempted to recompile the vtune drivers. Although the modules has been recompiled successfully, but the problem cannot be solved. The output of running ismod-sep is given as below:

$ sudo ./insmod-sep

You may need to build vtsspp driver for your kernel.
Please see the vtsspp driver README for instructions.

Checking for socwatch driver ... not detected.
Executing: insmod ./socwatch/drivers/socwatch2_10.ko
The socwatch driver has been successfully loaded.

I have already tried to increase the system stack limit to 65536, but the issue cannot be solved.

May anyone advise a solution?

Thank you and Regards,

Amon

Thanks for the report,

Could you please attach 'dmesg' command output after the driver loading failure.

BTW 'vtsspp' driver only affects collections with unlimited stack size sampling, collections w/o stacks or with limited stack size (2kb by default) should work.
