I have installed intree qat kernel driver modules, so used, 
./configure --prefix=/opt/openssl/3.0.15 --with-openssl_install_dir=/opt/openssl/3.0.15 --with-openssl_dir=/home/sas/openssl-3.0.15 --host=x86_64-linux-gnu --build=x86_64-linux-gnu --enable-qat_hw

in qat engine.

Could you please advise what I might be missing?

Thank you

Hi padmanabhanvg,

I'm looking into this issue at the moment. Meanwhile, could you please provide the icp_dump? You can generate it by executing the script found at $ICP_ROOT/quickassist/utilities/debug_tool/icp_dump.sh. This will produce a tar file that includes your complete system setup and configuration files.

Regards,

Hi Ronny,

Please find the attached file from icp dump.


Thanks,
