BTW, I tried to change this value by adding "-F" and "200" into the

into line 42 of perf-mem.c - just after the

You would need to increase the array size too.
Ouch! You're right! I forgot that!
Unfortunately, this seems to break something and
perf segfaults often. Which is the most appropriate way to tune the
user frequency of perf mem?
Best would be probably to fix it to pass through unknown
options, then -F/-c could be just used. I'm not sure
if this is possible easily with the git option parser.
Sorry, I'm not sure what is the "git option parser" here.
I think that this could be implemented extending the mem_options[] in
file builtin-mem.c lines 205-221.
Alternatively you can just specify the command line perf mem record
would specify directly to perf record, plus -c/-F
-andi
Thank you very much Andi.
