It allows to * resolve conflicts between global -mem-prealloc and hostmem's "policy" op= tion fixing premature allocation before binding policy is applied * simplify complicated memory allocation routines which had to deal with 2= ways to allocate RAM. * it allows to reuse hostmem backends of a choice for main RAM without add= ing extra CLI options to duplicate hostmem features. 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 pa= tches) - "numa: remove deprecated -mem-path fallback to anonymous RAM" - "numa: remove deprecated implicit RAM distribution between nodes" - "forbid '-numa node,mem' for 5.0 and newer machine types" Conversion introduces a new machine.ram-memdev property and wrapper code th= at aliases global -mem-path and -mem-alloc into automatically created hostmem backend properties (provided ram-memdev was not set explicitly by user). And then follows bulk of trivial patches that incrementally convert individ= ual boards to using machine.ram-memdev provided MemoryRegion. Board conversion typically involves: * providing MachineClass::default_ram_size and MachineClass::default_ram_i= d so generic code could create default backend if user didn't explicitly p= rovide ram-memdev or -m options * dropping memory_region_allocate_system_memory() call * using covinience MachineState::ram MemoryRegion, which points to MemoryR= egion allocated by ram-memdev On top of that for some boards: * added missing ram_size checks (typically it were boards with fixed ram s= ize) * ram_size fixups were replaced by checks and hard errors, forcing user to provide correct "-m" values instead of ignoring it and continuing runnin= g. =20 After all boards are converted the old API is removed and memory allocation routines are cleaned up. git tree for testing: https://github.com/imammedo/qemu convert_main_ram_to_memdev_v1 Igor Mammedov (86): numa: remove not needed check numa: properly check if numa is supported numa: remove deprecated -mem-path fallback to anonymous RAM machine: introduce ram-memdev property machine: alias -mem-path and -mem-prealloc into memory-foo backend machine: introduce convenience MachineState::ram initialize MachineState::ram in NUMA case alpha:dp264: use memdev for RAM arm:aspeed: convert valid RAM sizes to data arm:aspeed: actually check RAM size hw:aspeed: drop warning and bogus ram_size fixup arm:aspeed: use memdev for RAM arm:collie: use memdev for RAM arm:cubieboard: use memdev for RAM arm:digic_boards: use memdev for RAM arm:highbank: use memdev for RAM arm:imx25_pdk: drop RAM size fixup arm:imx25_pdk: use memdev for RAM arm:integratorcp: use memdev for RAM arm:kzm: drop RAM size fixup arm:kzm: use memdev for RAM arm:mcimx6ul-evk: use memdev for RAM arm:mcimx7d-sabre: use memdev for RAM arm:mps2-tz: use memdev for RAM arm:mps2: use memdev for RAM arm:musicpal: use memdev for RAM arm:nseries: use memdev for RAM arm:omap_sx1: use memdev for RAM arm:palm: use memdev for RAM arm:raspi: use memdev for RAM arm:sabrelite: use memdev for RAM arm:sbsa-ref: use memdev for RAM arm:versatilepb: use memdev for RAM arm:vexpress: use memdev for RAM arm:virt: use memdev for RAM arm:xilinx_zynq: drop RAM size fixup arm:xilinx_zynq: use memdev for RAM arm:xlnx-versal-virt: use memdev for RAM arm:xlnx-zcu102: use memdev for RAM s390x:s390-virtio-ccw: use memdev for RAM null-machine: use memdev for RAM cris:axis_dev88: use memdev for RAM hppa: drop RAM size fixup hppa: use memdev for RAM x86:microvm: use memdev for RAM x86:pc: use memdev for RAM lm32:lm32_boards: use memdev for RAM lm32:milkymist: use memdev for RAM m68k:an5206: use memdev for RAM m68k:mcf5208: use memdev for RAM m68k:next-cube: use memdev for RAM mips:boston-cube: use memdev for RAM mips:mips_fulong2e: drop RAM size fixup mips:mips_fulong2e: use memdev for RAM mips:mips_jazz: use memdev for RAM mips:mips_malta: use memdev for RAM mips:mips_mipssim: use memdev for RAM mips:mips_r4k: use memdev for RAM ppc:e500: drop RAM size fixup ppc:e500: use memdev for RAM ppc:mac_newworld: use memdev for RAM ppc:mac_oldworld: use memdev for RAM ppc:pnv: use memdev for RAM ppc:ppc405_boards: add RAM size checks ppc:ppc405_boards: use memdev for RAM ppc:ppc440_bamboo/sam460ex: drop RAM size fixup ppc:ppc440_bamboo/sam460ex: use memdev for RAM ppc:prep: use memdev for RAM ppc:spapr: use memdev for RAM ppc:virtex_ml507: remove unused arguments ppc:virtex_ml507: use memdev for RAM sparc:leon3: use memdev for RAM sparc:sun4m: use memdev for RAM sparc:niagara: use memdev for RAM remove no longer used memory_region_allocate_system_memory() post conversion default_ram_id cleanup exec: cleanup qemu_minrampagesize()/qemu_maxrampagesize() exec: drop bogus mem_path from qemu_ram_alloc_from_fd() make mem_path local variable hostmem: introduce "prealloc-threads" property hostmem: fix strict bind policy numa: forbid '-numa node,mem' for 5.0 and newer machine types tests:numa-test: make top level args dynamic and g_autofree(cli) cleanups tests:numa-test: use explicit memdev to specify node RAM numa: make exit() usage consistent numa: remove deprecated implicit RAM distribution between nodes hw/alpha/alpha_sys.h | 2 +- include/hw/boards.h | 51 ++++--------- include/hw/misc/aspeed_sdmc.h | 2 + include/hw/ppc/ppc4xx.h | 9 +-- include/sysemu/hostmem.h | 20 ++++- include/sysemu/numa.h | 5 +- include/sysemu/sysemu.h | 2 -
