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" - (POSTPONED, waiting on libvirt side) "forbid '-numa node,mem' for 5.0= and newer machine types" - (POSTPONED) "numa: remove deprecated implicit RAM distribution betwee= n nodes" Conversion introduces a new machine.memory-backend property and wrapper cod= e that aliases global -mem-path and -mem-alloc into automatically created hostmem backend properties (provided memory-backend was not set explicitly given by= user). And then follows bulk of trivial patches that incrementally convert individ= ual boards to using machine.memory-backend 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 memory-backend or -m options * dropping memory_region_allocate_system_memory() call * using convenience MachineState::ram MemoryRegion, which points to Memory= Region 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. 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_v3 previous rev: https://github.com/imammedo/qemu convert_main_ram_to_memdev_v2 https://lists.nongnu.org/archive/html/qemu-devel/2020-01/msg02960.html Igor Mammedov (77): numa: remove deprecated -mem-path fallback to anonymous RAM machine: introduce memory-backend 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: actually check RAM size 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: 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() 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 tests:numa-test: make top level args dynamic and g_autofree(cli) cleanups tests:numa-test: use explicit memdev to specify node RAM Philippe Mathieu-Daud=C3=A9 (3): hw/hppa/machine: Correctly check the firmware is in PDC range hw/hppa/machine: Restrict the total memory size to 3GB hw/hppa/machine: Map the PDC memory region with higher priority hw/alpha/alpha_sys.h | 2 +- include/hw/boards.h | 48 +++++---------- include/hw/misc/aspeed_sdmc.h | 1 + include/hw/ppc/ppc4xx.h | 9 ++- include/sysemu/hostmem.h | 20 +++++- include/sysemu/numa.h | 1 + include/sysemu/sysemu.h | 2 -
