Subject: [Qemu-devel] [PATCH for 2.13 0/2] target/ppc: Support adding memory to initially memory-less NUMA nodes
Date: Thu,  5 Apr 2018 10:35:21 -0400	[thread overview]
Message-ID: <1522938923-96058-1-git-send-email-spopovyc@redhat.com> (raw)

Now PowerPC Linux kernel supports hot-add to NUMA nodes not populated
initially with memory we can enable such support in qemu. This requires
two changes:

  o Add device tree property "ibm,max-associativity-domains" to let
    guest kernel chance to find max possible NUMA node

  o Revert  commit b556854bd852 ("spapr: Don't allow memory hotplug to
    memory less nodes") to remove check for hot-add to memory-less node.

See description messges for individual changes for more details.

  Revert "spapr: Don't allow memory hotplug to memory less nodes"
  spapr: Add ibm,max-associativity-domains property
