[Qemu-devel] [PATCH 1/3] numa: move numa global variable nb_numa_nodes into MachineState |
Date: |
Thu, 4 Apr 2019 11:34:27 +0800 |
The aim of this patch is to add struct NumaState in MachineState
and move existing numa global nb_numa_nodes into NumaState.
And add variable numa_support into MachineClass to decide which
submachines support NUMA.
