Hi,
This is the next version of memory hotplug support patchset for PowerPC
sPAPR guests. This is a split-out from the previous version (v3) that
was carrying CPU and memory hotplug together.
This patchset applies on spapr-next branch of David Gibson's tree with
the other prerequisite patchset applied. Pre-requistes patchset was
posted at:
https://lists.gnu.org/archive/html/qemu-devel/2015-06/msg05157.html
Changes in v4
-------------
- Supporting only 32 DIMM slots since PowerPC kernel supports 32.
- LMB DR connectors are now created at boot time instead of creating
them during ibm,client-architecture-support call. This enables
hot adding memroy to a migrated VM.
- Imposing the restriction that node memory size and max memory size
be in multiples of SPAPR_MEMORY_BLOCK_SIZE (256M).
- Ensure address@hidden for RMA ends in the 1st node that has non-zero
node size.
- Make hash table size dependent on maxram_size instead of ram_size.
- Allow hotplug to nodes other than NUMA node 0.
- No duplication of hotplug code from pc_dimm_plug().
v3: https://lists.nongnu.org/archive/html/qemu-devel/2015-04/msg02910.html
The memory hotplug feature requires updated version of powerpc-utils
and ppc64-diag packages in the guest.
Bharata B Rao (5):
spapr: Initialize hotplug memory address space
spapr: Add LMB DR connectors
spapr: Support ibm,dynamic-reconfiguration-memory
spapr: Make hash table size a factor of maxram_size
spapr: Memory hotplug support
