The following JEP is proposed to target JDK 25:

  509: JFR CPU-Time Profiling (Experimental)
       https://openjdk.org/jeps/509

  Summary: Enhance the JDK Flight Recorder (JFR) to capture CPU-time
  profiling information on Linux.  This is an experimental feature.

Feedback on this proposal from JDK Project Committers and Reviewers [1]
is more than welcome, as are reasoned objections.  If no such objections
are raised by 17:00 UTC on Wednesday, 4 June, or if they’re raised and
then satisfactorily answered, then per the JEP 2.0 process proposal [2]
I’ll target this JEP to JDK 25.
