Issues in using the hardware path with IAA #28
Description
I am using an Intel(R) Xeon(R) Platinum 8460H machine with Ubuntu 22.04 LTS.
I built QPL and I am able to run the compression example on ~/qpl_library/examples/low-level-api/examples/compression_example.cpp with the software path.
However with the hardware path when I compile and run:
g++ -I/home/raunaks3/qpl_library/qpl_installation/include -o compression_example compression_example.cpp /home/raunaks3/qpl_library/qpl_installation/lib/libqpl.a -ldl
sudo ./compression_example hardware_path
I am getting:
The example will be run on the hardware path.
An error 503 acquired during job initializing.
When I run sudo accel-config list this is the output:

iax1 seems to be enabled. What could be the reason for the issue?
