Lack of perf PMU event

[RainM]

Hi,

It's impossible to record plain PMU events like mispredicted branches with perf-java-recors-stack. This script supports profiling with specified frequency only (-F argument).

I'd like to propose either add one more script (like perf-java-record-stacks) which is able to record PMU events or modify existing perf-java-record-stack script in order to let user to specify PMU event to profile. If you are ok for these changes, I would implement it.

"This script supports profiling with specified frequency only (-F argument)." - Which script?
E.g. with the flames graph script the following works for me:
./perf-java-flames <pid> -e LLC-store-misses
