Peter Bacsko created YARN-9265:
----------------------------------
Summary: FPGA plugin fails to recognize Intel PAC card
Key: YARN-9265
URL: https://issues.apache.org/jira/browse/YARN-9265
Project: Hadoop YARN
Issue Type: Sub-task
Affects Versions: 3.1.0
Reporter: Peter Bacsko
The plugin cannot autodetect Intel FPGA PAC (Processing Accelerator Card).
There are two major issues.
Problem #1
The output of aocl diagnose:
{noformat}
--------------------------------------------------------------------
Device Name:
acl0
Package Pat:
/home/pbacsko/inteldevstack/intelFPGA_pro/hld/board/opencl_bsp
Vendor: Intel Corp
Physical Dev Name Status Information
pac_a10_f200000 Passed PAC Arria 10 Platform (pac_a10_f200000)
PCIe 08:00.0
FPGA temperature = 79 degrees C.
DIAGNOSTIC_PASSED
--------------------------------------------------------------------
Call "aocl diagnose <device-names>" to run diagnose for specified devices
Call "aocl diagnose all" to run diagnose for all devices
{noformat}
This generates the following error message:

{noformat}
Problem #2
The plugin assume that the file name under {{/dev}} can be derived from the
"Physical Dev Name". This is not the case. For example, it thinks that the
device file is {{ /dev/pac_a10_f300000}} which is not the case, the actual file
is {{/dev/intel-fpga-port.0}}.
