[Qemu-devel] [PATCH v5 0/7] QEMU memory hot unplug support

[Zhu Guihua]

Memory hot unplug are both asynchronous procedures.

And when guest OS finished handling unplug, unplug cb will be called
to do the real removal of device.

 -reorganize the patchset
 -add documentation to understand patch easily
 -add MEMORY_SLOT_EJECT for initiating device eject
 -add support to send qmp event to notify mgmt about memory unplug error

v4:
 -reorganize the patchset
 -drop the new API acpi_send_gpe_event()
 -update ssdt-mem

v3:
 -commit message changes
 -reorganize the patchset, squash and separate some patches
 -update specs about acpi_mem_hotplug
 -first cleanup external state, then un-map and un-register memory device

v2:
 -do a generic for acpi to send gpe event
 -unparent object by PC_MACHINE
 -update description in acpi_mem_hotplug.txt
 -combine the last two patches in the last version
 -cleanup external state in acpi_memory_unplug_cb
