Whether other implementers might retroactively define "equivalent" IIDR values for their existing implementations in a way we could potentially quirk in the driver is an orthogonal question.Agreed, it makes sense that supports the standard IP modules in the mainline kernel at this stage. Thanks for explanation.Leo, if you really want this to work on D06, I could also hack some out-of-tree perf tool patches for you. I'm not sure if you're interested in that. Let me know.
No, please don't spend time on this. I just use D06 platform to verify SMMUv3 relevant patches, but have no requirement for profiling SMMUv3 on it. Anyway, thanks a lot!
