This series removes ad hoc RAM allocation API (memory_region_allocate_system_memory) and consolidates it around hostmem backend. It allows to * resolve conflicts between global -mem-prealloc and hostmem's "policy" option, fixing premature allocation before binding policy is applied * simplify complicated memory allocation routines which had to deal with 2 ways to allocate RAM. * reuse hostmem backends of a choice for main RAM without adding extra CLI options to duplicate hostmem features. A recent case was -mem-shared, to enable vhost-user on targets that don't support hostmem backends [1] (ex: s390) * move RAM allocation from individual boards into generic machine code and provide them with prepared MemoryRegion. * clean up deprecated NUMA features which were tied to the old API (see patches) - "numa: remove deprecated -mem-path fallback to anonymous RAM" - (POSTPONED, waiting on libvirt side) "forbid '-numa node,mem' for 5.0 and newer machine types" - (POSTPONED) "numa: remove deprecated implicit RAM distribution between nodes" Introduce a new machine.memory-backend property and wrapper code that aliases global -mem-path and -mem-alloc into automatically created hostmem backend properties (provided memory-backend was not set explicitly given by user). A bulk of trivial patches then follow to incrementally convert individual boards to using machine.memory-backend provided MemoryRegion. Board conversion typically involves: * providing MachineClass::default_ram_size and MachineClass::default_ram_id so generic code could create default backend if user didn't explicitly provide memory-backend or -m options * dropping memory_region_allocate_system_memory() call * using convenience MachineState::ram MemoryRegion, which points to MemoryRegion allocated by ram-memdev On top of that for some boards: * missing ram_size checks are added (typically it were boards with fixed ram size) * ram_size fixups are replaced by checks and hard errors, forcing user to provide correct "-m" values instead of ignoring it and continuing running. After all boards are converted, the old API is removed and memory allocation routines are cleaned up. |
