Why do you think using irq_find_mapping to get the linux virt irq is not
standard way?

I did not search any example, currently it's just my idea based on my understanding
on irq domain design. Maybe i should give a patch to describe my idea,
then we can discuss on the patch.
Or did you see any example on using shift way to define device irq resource?
Then i can look at it.

If using linux virt irq, how do we avoid the issues i said in my last reply?
