Hi all,
ZGC is currently available on Linux/x64 and Linux/AArch64. There's
Candidate JEP to add macOS support [1]. We would also like to add
support for ZGC on Windows. I've prepared a JEP draft [2] for that work.
Most of the ZGC code base is platform independent and requires no
Windows-specific changes. The existing load barrier support for x64 is
OS agnostic and can also be used on Windows. The platform specific code
that needs to be ported relates to how address space is reserved and how
physical memory is mapped into a reserved address space.
Please see the details in the JEP for more information. Feedback is welcome!
Thanks,
StefanK
