[RFC PATCH-for-10.1 v6 00/14] target-info: Add more API for VirtIO cleanups & introduce ARM macros

[Philippe Mathieu-Daudé]

Rather than re-spinning the whole "single-binary: Make hw/arm/
common" series, restrict to the API additions, but include
examples of their usefulness (hundreds of virtio objects
removed from default Linux build).
Time passed since I context-switched out of this work so I'm
not sure the DEFINE_MACHINE_WITH_INTERFACES() implementation
is in the form Zoltan asked.

Philippe Mathieu-Daudé (14):
  target/qmp: Use target_cpu_type()
  qemu/target-info: Factor target_arch() out
  qemu/target-info: Add %target_arch field to TargetInfo
  qemu/target-info: Introduce target_base_arch()
  qemu/target-info: Add target_endian_mode()
  qemu: Convert target_words_bigendian() to TargetInfo API
  gdbstub/helpers: Replace TARGET_BIG_ENDIAN -> target_big_endian()
  qemu: Declare all load/store helpert in 'qemu/bswap.h'
  hw/virtio: Build various files once
  hw/core/null-machine: Define machine as generic QOM type
  hw/arm: Register TYPE_TARGET_ARM/AARCH64_MACHINE QOM interfaces
  hw/core: Allow ARM/Aarch64 binaries to use the 'none' machine
  hw/boards: Introduce DEFINE_MACHINE_WITH_INTERFACES() macro
  hw/arm: Add DEFINE_MACHINE_[ARM_]AARCH64() macros

[PATCH-for-10.1 v6 02/14] qemu/target-info: Factor target_arch() out

[Philippe Mathieu-Daudé]

To keep "qemu/target-info.h" self-contained to native
types, declare target_arch() -- which returns a QAPI
type -- in "qemu/target-info-qapi.h".

No logical change.

Keeping native types in "qemu/target-info.h" is necessary
to keep building tests such tests/tcg/plugins/mem.c, as
per the comment added in commit ecbcc9ead2f ("tests/tcg:
add a system test to check memory instrumentation"):

/*
 * plugins should not include anything from QEMU aside from the
 * API header. However as this is a test plugin to exercise the
 * internals of QEMU and we want to avoid needless code duplication we
 * do so here. bswap.h is pretty self-contained although it needs a
 * few things provided by compiler.h.

[PATCH-for-10.1 v6 04/14] qemu/target-info: Introduce target_base_arch()

[Philippe Mathieu-Daudé]

target_base_arch() returns the base architecture as in QEMU
target/$arch/ path. For example, X86_64 is implemented in the
target/i386/ so its QEMU base arch is 'i386'.

[PATCH-for-10.1 v6 09/14] hw/virtio: Build various files once

[Philippe Mathieu-Daudé]

[PATCH-for-10.1 v6 10/14] hw/core/null-machine: Define machine as generic QOM type

[Philippe Mathieu-Daudé]

While DEFINE_MACHINE() is a succinct macro, it doesn't
allow registering QOM interfaces to the defined machine.
Convert to the generic DEFINE_TYPES() in preparation to
register interfaces.

Ought this use DEFINE_MACHINE_WITH_INTERFACES that you introduce later?

[PATCH-for-10.1 v6 11/14] hw/arm: Register TYPE_TARGET_ARM/AARCH64_MACHINE QOM interfaces

[Philippe Mathieu-Daudé]

Define the TYPE_TARGET_ARM_MACHINE and TYPE_TARGET_AARCH64_MACHINE
QOM interface names to allow machines to implement them.

Register these interfaces in common code in target_info-qom.c used
by all binaries because QOM interfaces must be registered before
being checked (see next commit with the 'none' machine).

I think I'd prefer to defer cleanups to post 10.1 - already
too much on my plate as I was out sick. Unless there's a reason
I'm missing to rush this in? Is there a feature we want in
10.1 that depends on it?

This is all part of reducing the number of duplicate builds of device
models which after the stubs VirtIO is the main remaining sub-system due
for clean-up:

Aside from reducing build times and overall load on the CI systems its
required to advance the single-binary QEMU build and get us closer to
being able to do proper heterogeneous emulation.

I don't think missing 10.1 would be critical for the single binary proof
of concept but obviously as with all changes that touch the whole code
base the longer the review takes the more time they spend in re-base
hell.

Fair enough for the virtio patch.

Hopefully the previous ones (TargetInfo related, not touching
virtio) could get in (you don't have to look a them ;P).

I've sent the patch here:
https://patchew.org/QEMU/cover.1751494995.git.balaton@eik.bme.hu/3c2aa5b895adbb5244b643a6672603d65dce4298.1751494995.git.balaton@eik.bme.hu/
that will hopefully be merged before the freeze so you can rebase on that.

Sorry, I cut this branch incorrectly, I should have posted only up
to here, as the rest isn't required. I'll respin for clarity.
