virtio-mem: Mark memslot alias memory regions unmergeable (2023-10-12
14:15:22 +0200)
----------------------------------------------------------------
Hi,
"Host Memory Backends" and "Memory devices" queue ("mem"):
- Support memory devices with multiple memslots
- Support memory devices that dynamically consume memslots
- Support memory devices that can automatically decide on the number of
memslots to use
- virtio-mem support for exposing memory dynamically via multiple
memslots
- Some required cleanups/refactorings
----------------------------------------------------------------
David Hildenbrand (18):
vhost: Rework memslot filtering and fix "used_memslot" tracking
vhost: Remove vhost_backend_can_merge() callback
softmmu/physmem: Fixup qemu_ram_block_from_host() documentation
kvm: Return number of free memslots
vhost: Return number of free memslots
memory-device: Support memory devices with multiple memslots
stubs: Rename qmp_memory_device.c to memory_device.c
memory-device: Track required and actually used memslots in
DeviceMemoryState
memory-device,vhost: Support memory devices that dynamically consume
memslots
kvm: Add stub for kvm_get_max_memslots()
vhost: Add vhost_get_max_memslots()
memory-device,vhost: Support automatic decision on the number of memslots
memory: Clarify mapping requirements for RamDiscardManager
virtio-mem: Pass non-const VirtIOMEM via virtio_mem_range_cb
virtio-mem: Update state to match bitmap as soon as it's been migrated
virtio-mem: Expose device memory dynamically via multiple memslots if
enabled
memory,vhost: Allow for marking memory device memory regions unmergeable
virtio-mem: Mark memslot alias memory regions unmergeable
