L1D_CACHE_LMISS is not defined anywhere.


Good catch! I must have thought the python script would at least print a warning of missing event as I compared the build logs with and without the patch. I can prepare a fix for this and submit with another couple of patches. I'm hoping to be able to do that by the beginning of next week.

Thanks. I found it trying to port this to a 5.15 kernel which still uses the c program.
