Intel Devstack-OpenCL unable to detect PAC Cards

Intel Development Acceleration Stack for OpenCL is not detecting the Arria 10 PAC Cards on our server. It's looking for PAC drivers which cannot be found at the OpenCL_BSP installation path.

The Cards can be detected using `lspci` and `OPAE drivers` but not with `aocl diagnose` command:

System Specs:

OS: ubuntu - 18.04

The following is the log:

Hi @JohnT_Intel , Here's the output for lspci

server2@ubuntu:~$ lspci | grep acce
af:00.0 Processing accelerators: Intel Corporation Device 09c4

The FPGA is still available and only shows with lspci and fpgainfo. I think the problem is with the drivers. When I move the FPGA to a different system, It works there.

Hi,

Can you try "lspci -vv | grep acce" to get the kernel driver information.

Hi,

Thanks for providing the logfile. From the logfile, it looks like it automatically loaded with default PCIe driver. Please performed "modprobe -r intel-fpga-pci" then only performed "aocl install".

Thanks.

  Hi,
  
  Sorry for the delayed response.
  
  I couldn't fix the error occurring. So, I had to reinstall the OS and install the inteldevstack on it. It works now.
  
  Thanks, @JohnT_Intel for the support.
