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 docs/memory-hotplug.txt | 23 ++++++++-- docs/qmp/qmp-events.txt | 17 +++++++ docs/specs/acpi_mem_hotplug.txt | 58 +++++++++++++++++++++-- hw/acpi/aml-build.c | 4 +- hw/acpi/ich9.c | 19 ++++++-- hw/acpi/memory_hotplug.c | 96 ++++++++++++++++++++++++++++++++++++--- hw/acpi/piix4.c | 17 +++++-- hw/core/qdev.c | 2 +- hw/i386/acpi-build.c | 25 ++++++++-- hw/i386/acpi-dsdt-mem-hotplug.dsl | 13 +++++- hw/i386/pc.c | 62 +++++++++++++++++++++++-- include/hw/acpi/aml-build.h | 10 +++- include/hw/acpi/memory_hotplug.h | 12 +++++ include/hw/acpi/pc-hotplug.h | 3 ++ include/hw/qdev-core.h | 1 + monitor.c | 1 + qapi/event.json | 14 ++++++ trace-events | 4 ++ 18 files changed, 346 insertions(+), 35 deletions(-) -- 1.9.3
