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 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 v5 ------------- - Get rid of hotplug_mem_size alignment completely and start hotplug base right after RAM. (01/06) - Disable LMB DR and revert to older style of memory DT representation if RAM size, maxmem size or individual node memory sizes aren't aligned to SPAPR_MEMORY_BLOCK_SIZE (256M). (02/06) - Use dr_lmb_enabled from sPAPRMachineClass itself instead of copying it to sPAPRMachineState. (02/06) - Ensure memory@0 is created even when -numa option isn't specified. (03/06) - Calling pc_dimm_memory_unplug() when pc_dimm_memory_plug() fails isn't required. (05/06) - Added a new patch to prevent memory hotplug to memory-less nodes (06/06) v4: https://lists.gnu.org/archive/html/qemu-devel/2015-06/msg05242.html v3: https://lists.nongnu.org/archive/html/qemu-devel/2015-04/msg02910.html *** BLURB HERE *** Bharata B Rao (6): 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 spapr: Don't allow memory hotplug to memory less nodes default-configs/ppc64-softmmu.mak | 1 + docs/specs/ppc-spapr-hotplug.txt | 48 ++++ hw/ppc/spapr.c | 460 ++++++++++++++++++++++++++++++++++---- hw/ppc/spapr_events.c | 8 +- hw/ppc/spapr_hcall.c | 51 ++++- include/hw/ppc/spapr.h | 28 ++- 6 files changed, 542 insertions(+), 54 deletions(-) -- 2.1.0
