* hostmem: Wire up RAM_NORESERVE via "reserve" propertyDavid Hildenbrand2021-06-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's provide a way to control the use of RAM_NORESERVE via memory backends using the "reserve" property which defaults to true (old behavior). Only Linux currently supports clearing the flag (and support is checked at runtime, depending on the setting of "/proc/sys/vm/overcommit_memory"). Windows and other POSIX systems will bail out with "reserve=false". The target use case is virtio-mem, which dynamically exposes memory inside a large, sparse memory area to the VM. This essentially allows avoiding to set "/proc/sys/vm/overcommit_memory == 0") when using virtio-mem and also supporting hugetlbfs in the future. As really only Linux implements RAM_NORESERVE right now, let's expose the property only with CONFIG_LINUX. Setting the property to "false" will then only fail in corner cases -- for example on very old kernels or when memory overcommit was completely disabled by the admin.

* hostmem: fix strict bind policyIgor Mammedov2020-02-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When option -mem-prealloc is used with one or more memory-backend objects, created backends may not obey configured bind policy or creation may fail after kernel attempts to move pages according to bind policy. Reason is in file_ram_alloc(), which will pre-allocate any descriptor based RAM if global mem_prealloc != 0 and that happens way before bind policy is applied to memory range. One way to fix it would be to extend memory_region_foo() API and add more invariants that could broken later due implicit dependencies that's hard to track. Another approach is to drop adhoc main RAM allocation and consolidate it around memory-backend. That allows to have single place that allocates guest RAM (main and memdev) in the same way and then global mem_prealloc could be replaced by backend's property[s] that will affect created memory-backend objects but only in correct order this time. With main RAM now converted to hostmem backends, there is no point in keeping global mem_prealloc around, so alias -mem-prealloc to "memory-backend.prealloc=on" machine compat[*] property and make mem_prealloc a local variable to only stir registration of compat property. *) currently user accessible -global works only with DEVICE based objects and extra work is needed to make it work with hostmem backends. But that is convenience option and out of scope of this already huge refactoring. Hence machine compat properties were used.
