Intel Devstack-OpenCL unable to detect PAC Cards

1,083 Views

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,


Can you try to performed "lspci" and check if the driver is bind to the device? The reason is that when you are performing uninstall, the driver is not bind to the device.

For some reason, `aocl install` command is searching for the driver folder which is non-existent in the BSP.

 

I'm not sure how to diagnose this.

Hi,


Can you check your "'/home/server2/inteldevstack/a10_gx_pac_ias_1_2_1_pv/opencl/opencl_bsp/linux64"? I suspect that you have not un-archive or unzip the opencl BSP.


Thanks

Hi,


From the latest log, it looks like it is able to installed the driver. Can you double confirm using "lspci" to see if the driver is loaded into the FPGA card?

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,


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.
