[PATCH 0/8] multi-target: remove qmp_query_cpu_definitions duplication

[Pierrick Bouvier]

This series allows to link multiple targets that define
qmp_query_cpu_definitions. It simply replaces the duplicated definitions with
target-specific ones and a single dispatcher. We didn't use yet the dispatcher
pattern, and it's the first situation where it appears to be a good fit.

A possible alternative would be to introduce this callback directly at
target-info level, which I think is a less desirable solution, since it would
ties this API to monitor.

If the approach here is accepted, I'll extend this series with
qmp_query_cpu_model_expansion which follows the same pattern.
With this, we'll be free to link together almost all the base architectures.

Pierrick Bouvier (8):
  target/arm: rename qmp_query_cpu_definitions to
    qmp_query_arm_cpu_definitions
  target/i386: rename qmp_query_cpu_definitions to
    qmp_query_i386_cpu_definitions
  target/loongarch: rename to qmp_query_loongarch_cpu_definitions
  target/mips: rename qmp_query_cpu_definitions to
    qmp_query_mips_cpu_definitions
  target/ppc: rename qmp_query_cpu_definitions to
    qmp_query_ppc_cpu_definitions
  target/riscv: rename to qmp_query_cpu_definitions to
    qmp_query_riscv_cpu_definitions
  target/s390x: rename qmp_query_cpu_definitions to
    qmp_query_s390x_cpu_definitions
  qmp: reimplement qmp_query_cpu_definitions as a dispatcher function

[PATCH 1/8] target/arm: rename qmp_query_cpu_definitions to qmp_query_arm_cpu_definitions

[Pierrick Bouvier]

In a future commit, a single target-agnostic qmp_query_cpu_definitions()
will dispatch call to the per-architecture implementations based on
target_arch(). Introduce the header holding those declarations and
rename the arm implementation.

We keep the existing qmp_query_cpu_definitions() function to not break
the build.

[PATCH 8/8] qmp: reimplement qmp_query_cpu_definitions as a dispatcher function

[Pierrick Bouvier]

Now that we have per target implementations of this function, we simply
dispatch the call to relevant implementation.
This eliminates duplication of qmp_query_cpu_definitions symbol.

Re: [PATCH 8/8] qmp: reimplement qmp_query_cpu_definitions as a dispatcher function

Pierrick Bouvier <pierrick.bouvier@oss.qualcomm.com> writes:

> Now that we have per target implementations of this function, we simply
> dispatch the call to relevant implementation.

I believe the stubs are needed to make hw/core/machine-qmp-cmds.c link
when targets are compiled out.  Suggest to briefly explain that in the
commit message.

Introduce this callback directly at target-info level wil avoid these
stubs/qmp-*, basically we indeed can remove more stubs. maybe
qmp-cpu.c be removed.

Here is my DRAFT patch, you can take a look about this direction, and
change far less code.

I'm curious... why would such a tie be undesirable?

We have a unique definition of target-info for all targets 
(https://gitlab.com/qemu-project/qemu/-/blob/master/target-info-def.c), 
which is simple and nice.

We could consider adding callbacks in this "generic" file only if they 
are implemented for all targets, but as we can see in this series, only 
a few targets implement this. It would be more boilerplate for the same 
result.

IMHO the two concerned functions (qmp_query_cpu*) look more like an 
exception than a proper rule. dump functions (posted in another series) 
are more related to cpu, and not to target themselves.

I would happy to revisit this if community prefers to go in a different 
direction though.

I personally think we can call it "generic" if three or more targets
are implemented, otherwise it's too restricted. And also get it hard if
new targets want to leverage/implement it.


Anyway, this series is still fine, I have no objection, just some points.

I don't think target-info should be involved at all, it is a problem
to solve in the CPU type system. The CPU definitions are introspecting
sub-classes of TYPE_CPU.

IMHO the right way to solve this is for CPUClass to gain a callback for
introspection, and for each target to provide an impl of that callback.

There should only be a single qmp_query_cpu_definitions method that
introspects all registered TYPE_CPU subclasses. That way in a
multi-target binary, the introspection will return info for all
CPUs for all compiled in targets.

That would need refactoring of the current qmp_query_cpu_definitions
methods which is a bigger job. This series as is, is a reasonable
small initial stepping stone to make it possible to link the binaries,
before a later followup patch to do the full refactoring to get the
desirable API semantics.

With regards,
Daniel

I was wondering if what we would like to expose is all targets, or only
the ones that have a cpu active.
