Merge tag 'pull-target-arm-20231102' of https://git.linaro.org/people/pmaydell/qemu-arm into staging (2023-11-03 10:04:12 +0800) are available in the Git repository at: https://github.com/maciejsszmigiero/qemu.git tags/pull-hv-balloon-20231105 for you to fetch changes up to 2b49ecabc6bf15efa6aa05f20a7c319ff65c4e11: MAINTAINERS: Add an entry for Hyper-V Dynamic Memory Protocol (2023-11-03 20:31:10 +0100) ---------------------------------------------------------------- Hyper-V Dynamic Memory protocol driver. This driver is like virtio-balloon on steroids for Windows guests: it allows both changing the guest memory allocation via ballooning and inserting pieces of extra RAM into it on demand from a provided memory backend via Windows-native Hyper-V Dynamic Memory protocol. * Protocol definitions. * Hyper-V DM protocol driver (hv-balloon) base (ballooning only). * Hyper-V DM protocol driver (hv-balloon) hot-add support. * qapi query-memory-devices support for the driver. * qapi HV_BALLOON_STATUS_REPORT event. * The relevant PC machine plumbing. * New MAINTAINERS entry for the above. ---------------------------------------------------------------- David Hildenbrand (2): memory-device: Support empty memory devices memory-device: Drop size alignment check Maciej S. Szmigiero (7): Add Hyper-V Dynamic Memory Protocol definitions Add Hyper-V Dynamic Memory Protocol driver (hv-balloon) base Add Hyper-V Dynamic Memory Protocol driver (hv-balloon) hot-add support qapi: Add query-memory-devices support to hv-balloon qapi: Add HV_BALLOON_STATUS_REPORT event and its QMP query command hw/i386/pc: Support hv-balloon MAINTAINERS: Add an entry for Hyper-V Dynamic Memory Protocol Kconfig.host | 3 + MAINTAINERS | 8 + hw/core/machine-hmp-cmds.c | 15 + hw/hyperv/Kconfig | 10 + hw/hyperv/hv-balloon-internal.h | 33 + hw/hyperv/hv-balloon-our_range_memslots.c | 201 ++++ hw/hyperv/hv-balloon-our_range_memslots.h | 110 ++ hw/hyperv/hv-balloon-page_range_tree.c | 228 ++++ hw/hyperv/hv-balloon-page_range_tree.h | 118 ++ hw/hyperv/hv-balloon.c | 1766 +++++++++++++++++++++++++++++ hw/hyperv/meson.build | 1 + hw/hyperv/trace-events | 18 + hw/i386/Kconfig | 1 + hw/i386/pc.c | 22 + hw/mem/memory-device.c | 49 +- include/hw/hyperv/dynmem-proto.h | 423 +++++++ include/hw/hyperv/hv-balloon.h | 18 + include/hw/mem/memory-device.h | 7 +- meson.build | 28 +- meson_options.txt | 2 + monitor/monitor.c | 1 + qapi/machine.json | 101 +- scripts/meson-buildoptions.sh | 3 + 23 files changed, 3153 insertions(+), 13 deletions(-) create mode 100644 hw/hyperv/hv-balloon-internal.h create mode 100644 hw/hyperv/hv-balloon-our_range_memslots.c create mode 100644 hw/hyperv/hv-balloon-our_range_memslots.h create mode 100644 hw/hyperv/hv-balloon-page_range_tree.c create mode 100644 hw/hyperv/hv-balloon-page_range_tree.h create mode 100644 hw/hyperv/hv-balloon.c create mode 100644 include/hw/hyperv/dynmem-proto.h create mode 100644 include/hw/hyperv/hv-balloon.h
