Subject: [PATCH 00/86] refactor main RAM allocation to use hostmem backend
Date: Tue, 31 Dec 2019 14:02:44 +0100 [thread overview]
Message-ID: <1577797450-88458-1-git-send-email-imammedo@redhat.com> (raw)
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"
- "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 that
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 individual
boards to using machine.ram-memdev 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
ram-memdev or -m options
* dropping memory_region_allocate_system_memory() call
* using covinience 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.
