[Qemu-devel] [PATCH v6 0/8] QEMU memory hot unplug support |
Date: |

This patchset adds support to hot unplug memory.
Memory hot unplug is complicated multi-stage process. Unplug request callback
sends remove request. After guest os processes ejection request, OSPM will
execute _EJ0 to signal qemu that a device eject will be to occur. Then qemu
will call unplug callback to eject the device.
v6:
-improve documentation of memory hot unplug
-add trace event for device deletion
-put fix about "Memory device control fields" register in a separate patch
v5:
-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
Tang Chen (3):
acpi, mem-hotplug: add acpi_memory_slot_status() to get MemStatus
acpi, mem-hotplug: add unplug request cb for memory device
acpi, mem-hotplug: add unplug cb for memory device
Zhu Guihua (5):
docs: update documentation for memory hot unplug
acpi: extend aml_field() to support UpdateRule
acpi: fix "Memory device control fields" register
acpi: add hardware implementation for memory hot unplug
qmp-event: add event notification for memory hot unplug error
