Greetings,
This is the implementation of JEP [JDK-8350338 Cooperative JFR Sampling](https://bugs.openjdk.org/browse/JDK-8350338).
Implementations in this change set are provided and have been tested on the following platforms:
- windows-x64 - windows-x64-debug - linux-x64 - linux-x64-debug - macosx-x64 - macosx-x64-debug - linux-aarch64 - linux-aarch64-debug - macosx-aarch64 - macosx-aarch64-debug
Testing: tier1-6, jdk_jfr, stress testing.
Platform porters note: Some platform-specific code needs to be provided, mainly in the interpreter. Take a look at the following files for changes:
- src/hotspot/cpu/x86/frame_x86.cpp - src/hotspot/cpu/x86/interp_masm_x86.cpp - src/hotspot/cpu/x86/interp_masm_x86.hpp - src/hotspot/cpu/x86/javaFrameAnchor_x86.hpp - src/hotspot/cpu/x86/macroAssembler_x86.cpp - src/hotspot/cpu/x86/macroAssembler_x86.hpp - src/hotspot/cpu/x86/templateInterpreterGenerator_x86.cpp - src/hotspot/cpu/x86/templateTable_x86.cpp - src/hotspot/os_cpu/linux_x86/javaThread_linux_x86.hpp
