Sampling driver installation error

I am using an AWS EC2 instance (r6in.2xlarge) which uses the Intel Xeon 8375C (Ice Lake) with an Ubuntu 22.04 image. I am followed all instructions to ensure I have the system requirements for the intel oneapi base kit, which was downloaded successully. However to use some tools such as the microarchitecture performance insights, I need the sampling drivers. However, I get the following problem:

Failed to build the drivers

 

 

I have followed this thread: https://community.intel.com/t5/Analyzers/Unable-to-build-sepdk-driver/m-p/1369494#M21980 but it hasn't helped my case. Is there a reason why this is happening ? Can anyone point me to a fix ? Thanks.

An update to the post above:

When I ran ./insmod-sep -q, I get the following:

ubuntu@ip-172-31-86-17:/opt/intel/oneapi/vtune/2023.0.0/sepdk/src$ ./insmod-sep -q
pax driver is loaded and owned by group "vtune" with file permissions "660".
socperf3 driver is not correctly loaded.
sep5 driver is not correctly loaded.

socwatch driver is loaded and owned by group "vtune" with file permissions "660".

 I tried to follow Vladimir_T_Intel's advice from https://community.intel.com/t5/Analyzers/Sampling-drivers-not-loaded-correctly/m-p/1184259 where I fully unloaded the driver (./rmmod-sep -s) and loaded it again (./insmod-sep). After that, this is the output:

Hi,

 

Thank you for posting in Intel communities.

 

We are unable to reproduce your issue. We followed the same steps for loading the drivers in Ice Lake machine(Ubuntu 22.04). All the drivers were loaded successfully without any error messages.

We assume, the reason could be because of using the AWS EC2 instance. Could you please try loading the drivers without using EC2 instance and let us know the results

Unfortunately, I need to use the EC2 Instance to access the a system with an Intel Xeon. I have tried this with both the r5.metal and r6in.2xlarge instances. Both fail to install the drivers properly.

I ended up here looking for a explanation of the "warning: objtool" and "skipping BTF" messages when building the drivers from the source in OneAPI 2024.0.  My drivers seem to have built correctly but I'd like to understand what those two notifications mean and whether they have any implications I should know of.

 

(we built the drivers but have not yet installed them)

Skipping BTF generation for sepint5.ko due to unavailability of vmlinux

  • Caused by vmlinux file missing in the kernel header/source on the system.
  • This is the environment issue

 

Warning:objtool: SYS_Get_GDT_Base()+0x3: ‘naked’ return found in RETHUNK build

  • Caused by improper use of assembly code in the driver since some changes from kernel.

 

They both are warnings, so there is no impact to the driver functionality.
