v5:
- pick up new Reviewed-by-s
- drop "ppc/prep: use memdev for RAM" since machine was removed
- add patch "mips/mips_jazz: add max ram size check"
- extend comment for "default_ram_id" to clarify that's setting it serves
as optin flag for -m support. [03/79]
- rebase "arm/raspi: use memdev for RAM" once more
v4:
- pick up new Reviewed-by-s
- Fix access to uninitialized pagesize/hpsize in
"[PATCH REPOST v3 74/80] exec: cleanup
qemu_minrampagesize()/qemu_maxrampagesize()"
- Make explicitly provided memory-backend work by using string property
instead
of link so it would be possible to delay access to the backend to the time
when backends are initialized.
- added new patches to make explicit backend work nice with -m and do sanity
check on ram_size
'vl.c: move -m parsing after memory backends has been processed'
'vl.c: ensure that ram_size matches size of machine.memory-backend"
all this ram_size business needs cleanup too, but that's out of the scope
of this series.
- include m68k/q800 board into conversion
- drop patches that were merged through other trees
v3:
- due to libvirt not being ready, postpone till 5.1
* [PATCH v2 82/86] numa: forbid '-numa node, mem' for 5.0 and newer
machine types
and depended
[PATCH v2 86/86] numa: remove deprecated implicit RAM distribution
between nodes
- drop as not related "[PATCH v2 85/86] numa: make exit() usage consistent"
- drop "[PATCH v2 76/86] post conversion default_ram_id cleanup"
so that default memory-backedend won't be created for boards that do not
care
about -m. Which makes -m optin feature. We should decide what do in case
board doesn't use -m (but that's out of scope of this series)
- use object_register_sugar_prop() instead of hacking compat props directly
- simplified/reworked aspeed patches
- s/RAM_ADDR_FMT/size_to_str()/
- rename 'ram-memdev' property to 'memory-backend'
- minor fixes to numa-test
- fixes for issues noticed during review of
[PATCH v2 66/86] ppc/{ppc440_bamboo,sam460x}: drop RAM size fixup
v2:
- fix compile errors on mingw32 host by introducing RAM_ADDR_UFMT [11/86]
- replace "[PATCH 43/86] hppa: drop RAM size fixup" with alternative
patches made by Philippe (which effectively do the same thing but other
way around)
- ppc440: fix crash and add suggested valid RAM size in error output.
s/ppc4xx_sdram_adjust/ppc4xx_sdram_prep/ and simplify it by removing
not necessary nested loop
- rebase on current master due to new conflicts
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.
* it allows to reuse hostmem backends of a choice for main RAM without adding
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
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"
Conversion introduces 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).
And then follows bulk of trivial patches that 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:
* added missing ram_size checks (typically it were boards with fixed ram size)
* ram_size fixups were 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.
