After installing the oneAPI base toolkit on my Linux machine, emon dosent seem to see the SEP and PAX drivers

----------------------------

 shankar@b7r22u36:/opt/intel/oneapi/vtune/latest/sepdk/src$ emon -v
EMON Version .............. V11.30

Problem accessing the sampling driver. The driver may need to be (re)installed with appropriate group/file permissions

---------------------------------

The solution according to documentation seems to be 

$ cd <install-dir>/sepdk/src
$ ./insmod-sep -q
 
Dosent seem to solve the problem

Tried to build the drivers but that seems to be erroring out at the very end 

--------------------------------

************ Built drivers are copied to /opt/intel/oneapi/vtune/2022.0.0/sepdk/src/socwatch/drivers directory ************
Done
mv: target 'socwatch2_15-x32_64-5-x32_64-5.11.0-44-genericsmp.ko' is not a directory
make: *** [Makefile:224: default] Error 1

Failed to build the drivers

Hi,


Thankyou for posting in Intel Communities. 


Could you please try to install the sampling driver again.


cd <install-dir>/sepdk/src

./build-driver


Please follow the below link for more information to build the driver.

If the issue still persists please share the following details:


  1. OS you are using
  2. VTune version

Issue is still there. The clue to solving the issue is actually a bad mv statement in the Makefile

-------------------------

mv: target 'socwatch2_15-x32_64-5-x32_64-5.11.0-44-genericsmp.ko' is not a directory

-------------------------

The build is actually successful but he mv statement above errors out

Versions

1. OS NAME="Ubuntu"  VERSION="21.04 (Hirsute Hippo)"

2. Vtune : Intel(R) oneAPI VTune(TM) Profiler 2022.0.0 (build 621730)

3. Hardware : Intel(R) Xeon(R) Platinum 8380 CPU @ 2.10GHz
