I believe, Oracle JVM uses polling? This is the class responsible for safepoints: https://github.com/openjdk/jdk/blob/4b544f93ad0e2beae4c80e060cae727d143151ac/

I believe, Oracle JVM uses polling? This is the class responsible for safepoints: https://github.com/openjdk/jdk/blob/4b544f93ad0e2beae4c80e060cae727d143151ac/src/hotspot/share/runtime/safepointMechanism.hpp#L38 https://github.com/openjdk/jdk/blob/4b544f93ad0e2beae4c80e06... And this is one of the implementations: https://github.com/openjdk/jdk/blob/4b544f93ad0e2beae4c80e060cae727d143151ac/src/hotspot/cpu/riscv/macroAssembler_riscv.cpp#L3773 https://github.com/openjdk/jdk/blob/4b544f93ad0e2beae4c80e06... The arming code: https://github.com/openjdk/jdk/blob/4b544f93ad0e2beae4c80e060cae727d143151ac/src/hotspot/share/runtime/safepointMechanism.cpp#L94 https://github.com/openjdk/jdk/blob/4b544f93ad0e2beae4c80e06... I might be missing something, but I'd be terribly surprised if VM games are worth it.
