[Qemu-devel] [RFC PATCH v0 4/9] cpu: CPU socket backend |
Date: |
Thu, 10 Dec 2015 11:45:39 +0530 |
Backend object for CPU socket.
TODO: Prevent creation of socket objects beyond what is needed by
max_cpus so that all the required socket objects are pre-created
and user can't ever add a socket slot.
