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.
