Re: [PATCH 2/4] perf: jevents: Program to convert JSON file to C style file

[Andi Kleen]

Ok I did some scripting to add these topics you requested to the Intel JSON files,
and changed perf list to group events by them. 

I'll redirect any questions on their value to you.  
And I certainly hope this is the last of your "improvements" for now.

The updated event lists are available in

git://git.kernel.org/pub/scm/linux/kernel/git/ak/linux-misc perf/intel-json-files-3

The updated patches are available in 

git://git.kernel.org/pub/scm/linux/kernel/git/ak/linux-misc perf/builtin-json-6

Also posted separately.

The output looks like this
