Peter Bacsko updated YARN-9477:
-------------------------------
Description:
Right now we have a Python script which is able to discover VE cards using
pyudev.
Java does not officially support libudev. There are some projects on Github
(example: https://github.com/Zubnix/udev-java-bindings) but they're not
available as Maven artifacts.
However it's not terribly difficult to create a minimal layer around libudev
using JNA. We don't have to wrap every function, we need to call 4-5 methods.
