Yes, we have tested RC2 with latest schema patch. We used many xml files of different types of profile data to test VPA, e.g. profile data with single cpu single event, multiple cpu single event, or multiple cpu and multiple events, some xml files are with or without '-d' for detailed sections, some are with '-g' for debugging info in xml attributes, and so on. We have many xml files with different elements, attributes and sections then. In our testing, VPA did not refuse to accept any updated xml files in our all test cases. It seems the new schema conforms to the previous one well and we did not meet regression. But we did not let OProfile generate xml elements, for VPA has not supported it.





Thanks for testing.  I have a couple of follow-up questions:

I presume you tested RC2 with the latest schema version fixup patch that
I posted earlier this week, correct?

Sorry, but I don't understand what you mean below where you say: "No
file denying is found when we were testing our tool to visualize xml
files produced by latest patched oprofile, without containing callgraph
elements."  From the other statements you make, it sounds like your
testing went OK.  Please clarify.

Thanks.
