David Hildenbrand 766aa0a654 memory-device,vhost: Support memory devices that dynamically consume memslots ... We want to support memory devices that have a dynamically managed memory region container as device memory region. This device memory region maps multiple RAM memory subregions (e.g., aliases to the same RAM memory region), whereby these subregions can be (un)mapped on demand. Each RAM subregion will consume a memslot in KVM and vhost, resulting in such a new device consuming memslots dynamically, and initially usually 0. We already track the number of used vs. required memslots for all memslots. From that, we can derive the number of reserved memslots that must not be used otherwise. The target use case is virtio-mem and the hyper-v balloon, which will dynamically map aliases to RAM memory region into their device memory region container. Properly document what's supported and what's not and extend the vhost memslot check accordingly. Message-ID: <20230926185738.277351-10-david@redhat.com> Reviewed-by: Maciej S.
