Hi,
The thrid and last part (of "[PATCH v2 00/54] qapi: add #if
pre-processor conditions to generated code") is about adding schema
conditions based on the target.
For now, the qapi code is compiled in common objects (common to all
targets). This makes it impossible to add #if TARGET_ARM for example.
The patch "RFC: qapi: learn to split the schema by 'top-unit'"
proposes to split the schema by "top-unit", so that generated code can
be built either in common objects or per-target. That patch is a bit
rough, I would like to get some feedback about the approach before
trying to improve it. The following patches demonstrate usage of
target-based #if conditions, and getting rid of the
qmp_unregister_command() hack.
Marc-André Lureau (13):
build-sys: move qmp-introspect per target
qapi-commands: don't initialize command list in qmp_init_marshall()
qapi-commands: rename init_marshal() to register_commands()
RFC: qapi: learn to split the schema by 'top-unit'
qapi: add a top-unit 'target' schema
qapi: make rtc-reset-reinjection and SEV depend on TARGET_I386
qapi: make s390 commands depend on TARGET_S390X
target.json: add a note about query-cpu* not being s390x-specific
qapi: make query-gic-capabilities depend on TARGET_ARM
qapi: make query-cpu-model-expansion depend on s390 or x86
qapi: make query-cpu-definitions depend on specific targets
qapi: remove qmp_unregister_command()
qapi: move RTC_CHANGE to the target schema

The following patches are going to introduce per-target #ifdef in the
schemas.
The introspection data is statically generated once, and must thus be
built per-target to reflect target-specific configuration.
Drop "do_test_visitor_in_qmp_introspect(&qmp_schema_qlit)" since the
schema is no longer in a common object. It is covered by the per-target
query-qmp-schema test instead.

This will let the caller add several list of commands coming from
different schemas (the following patches split the schemas for common
and arch-specific parts).

The function only calls various register_command() now, use a more

A module can declare belonging to a 'top-unit', with the corresponding
pragma value (the default 'top-unit' is None).
The generators have a chance to break the generated output by
units (top-units are visited first). Generated types, visitors,
events and commands are split by 'top-unit'. Generated introspection
and documentation remain monolithic.
In the following commits, a 'target' unit is introduced. The generated
'target' files will be allowed to used poisoned defines for
conditional compilation, since they will be built with the target
objects.
TODO: if this approach is acceptable, split the patch, write tests & doc.
Note: I don't really have better ideas, but open for suggestions...

From: Marc-André Lureau @ 2018-12-16 14:08 UTC (permalink / raw)
To: qemu-devel; +Cc: armbru
Add a 'target' top-unit to be compiled seperately from the common qapi
modules. This will allow poisoned target #ifdef usage.
The generated commands must be registered seperately.
The events have a different enum, and must thus use a different
emitter/limiter.
The DUMMY event is there to force the visit of target, ensuring files
are built. It is removed in next commit.

This command is no longer needed, the schema has compile-time
configuration conditions.

A few targets don't emit RTC_CHANGE, we could restrict the event to
the tagets that do emit it.
Note: There is a lot more of events & commands that we could restrict
to capable targets, with the cost of some additional complexity, but
the benefit of added correctness and better introspection.
Note2: The rate limite could perhaps be part of the schema, and the
common event emitter code, to simplify the need of custom and #ifdef
code in the monitor.

Having to compile this multiple times is a bit sad, since it's fairly
big:
$ ls -lh qapi/qapi-introspect.c
-rw-rw-r--. 1 armbru armbru 518K Dec 17 07:56 qapi/qapi-introspect.c
$ size x86_64-softmmu/qapi/qapi-introspect.o
text data bss dec hex filename
16302 289472 48 305822 4aa9e x86_64-softmmu/qapi/qapi-introspect.o
To compile its target-independent part just once, we'd have to split it
up. May or may not improve compile time. We can figure it out when
compiling all of it multiple times bother us.

misc.json is a bit of a kitchen sink. I'd prefer not to include it
here, but instead factor out the bits we actually need into a new .json.
I suspect that would be an improvement all by itself.

Lovely except for the 'top-unit' feature. I believe the existing
modules can do the job. Quoting my "[PATCH v2 00/29] Modularize
generated QAPI code":
Related: Marc-André's 'unit' pragma proposal. That's a different
way to split off parts of the generated code, motivated by the
desire to use poisoned identifiers such as TARGET_I386. I noted in
my review of v3 that I "can either accept it, or come up with a
better solution." This is my attempt at a better solution. It's a
bit more ambitious, and thus more useful (I hope). The pragma has
one theoretical advantage, though: you can modularize the generated
output in different ways than the input. The patches using don't do
that, however.
I'm going to post RFC patches that show how to do a target-dependent
module. Then we can discuss the two approaches.
