Hi, Jiri & Jakub

    Generally, a devlink instance is created for each PF/VF. This
facilitates the query and configuration of the settings of each
function. But if some common objects, like the health status of
the entire ASIC, the data read by those instances will be duplicate.

    So I wonder do I just need to apply a public devlink instance for the
entire ASIC to avoid reading the same data? If so, then I can't set
parameters for each function individually. Or is there a better suggestion
to implement it?

I don't think there is a great way to solve this today. In my mind
devlink instances should be per ASIC, but I never had to solve this
problem for a multi-function ASIC. 

Can you assume all functions are in the same control domain? Can they
trust each other?
