[Qemu-devel] [PATCH v6 0/6] Memory hotplug for PowerPC sPAPR guests

[Bharata B Rao]

Hi,

This is v5 of memory hotplug support patchset for PowerPC
sPAPR guests.

This patchset applies on spapr-next branch of David Gibson's tree with
pc_dimm_pug reorg+NUMA node lookup patchset v4:
http://lists.nongnu.org/archive/html/qemu-devel/2015-06/msg07174.html

Changes in v6
-------------
- Rebased on top of latest pc_dimm_reorg+NUMA node lookup patchset v4.
- Instead of silently disabling memory hotplug, refuse to boot with memory
  configurations where RAM size or maxmem size or node memory size isn't
  aligned to SPAPR_MEMORY_BLOCK_SIZE(256MB). (2/6)
- Pushed a recoverable error check (hotplug mem size not aligned to 256MB)
  from spapr_add_lmbs() down to spapr_memory_plug() so that we can
  pass error_abort to spapr_add_lmbs() and let it abort in case of errors.
  This is in line with Igor's observation that we shouldn't fail and hence
  shouldn't try recovery after we have done guest visible changes. (5/6)
