[PATCH v5 0/4] docs/interop/firmware.json: scripts/qapi-gen.py compatibility

[PATCH v5 0/4] docs/interop/firmware.json: scripts/qapi-gen.py compatibility

[Thomas Weißschuh]

docs/interop/firmware.json is currently not usable with qapi-gen.py due
to various non-functional issues.
Fix those issue to provide compatibility.

Sorry for the quick resend, but the series got broken by the just-merged
pull "pull-qapi-2024-07-17" which made the newly introduced patch 3
necessary.

[PATCH v5 1/4] docs/interop/firmware.json: add new enum FirmwareFormat

[Thomas Weißschuh]

Only a small subset of all blockdev drivers make sense for firmware
images. Introduce and use a new enum to represent this.

This also reduces the dependency on firmware.json from the global qapi
definitions.

It's not the only QEMU image format...  Maybe "The QCOW2 image format."
Almost tautological, but I don't have better ideas.

The enum type is indeed since 9.1, but its two members are since 3.0,
and that's what matters.

I used the wording from qemu-img(1).
If you prefer "The QCOW2 image format", I'll switch to that.

Ack.

So I change the Since: of the whole enum?
And not on the individual members?

Interesting, wasn't aware.

Up to you, unless Kevin or Hanna have a preference.

Whole enum is simpler, so that's what I'd do.  Perhaps with a brief
explanation in the commit message.  Here's my try:

    Claim "Since: 3.0" for the new enum, because that's correct for its
    members, and the members are what matters in the interface.

For slightly less tautology, not sure these are any better:

    @raw: Disk image format that's plain and unstructured.

    @qcow2: Disk image format with support for copy-on-write and more.

[PATCH v5 2/4] docs/interop/firmware.json: add new enum FirmwareArchitecture

[Thomas Weißschuh]

Only a small subset of all architectures supported by qemu make use of
firmware files. Introduce and use a new enum to represent this.

This also removes the dependency to machine.json from the global qapi
definitions.

docs/devel/qapi-code-gen.rst section "Documentation markup":

    For legibility, wrap text paragraphs so every line is at most 70
    characters long.

> +# The values are a subset of the enum SysEmuTarget.

Will consumers of firmware.json care for this?  Or is it just a reminder
for developers to keep the two enums in sync?

The enum type is indeed since 9.1, but its members are since 3.0, and
that's what matters.  Except for @loongarch, which is since 7.1.0 (not
documented in qapi/machine.json; I'll fix that).

Most probably not.

I guess so.

You can drop it.

If you think it's useful for developers, you can instead make it a
non-doc comment, like ...

... here:

      # The values are a subset of the enum SysEmuTarget defined in
      # qapi/machine.json.

If you do, consider adding a similar note to FirmwareFormat in the
previous patch.

[PATCH v5 3/4] docs/interop/firmware.json: convert "Example" section

[Thomas Weißschuh]

Since commit 3c5f6114d9ff ("qapi: remove "Example" doc section")
the "Example" section is not valid anymore.
It has been replaced by the "qmp-example" role.

This was not detected earlier as firmware.json was not validated.
As this validation is about to be added, adapt firmware.json.

Make that "directive" instead of role.
