[Qemu-devel] [PATCH v6 0/3] fix query-command-line-options

[Qemu-devel] [PATCH v6 0/3] fix query-command-line-options

[Amos Kong]

This patchset fixed some issues of query-command-line-options:
 * some new options that haven't argument can't be queried. (eg: -enable-fips)
 * some legacy options that have argument can't be queried. (eg: -vnc display)

V2: remove duplicate option tables, update schema (eric)
V3: fix typo in commitlog and export qemu_options talbe (eric)
V4: avoid the duplicate static table (eric)
V5: rename new field, other fix (markus)
V6: add implied-name (eric, markus)

Thanks for your review!

[Qemu-devel] [PATCH v6 2/3] query-command-line-options: expose implicit parameter name

[Amos Kong]

This patch added a new field to expose implicit parameter name,
we make it optional for compatibility.

[Qemu-devel] [PATCH v6 3/3] query-command-line-options: query all the options in qemu-options.hx

[Amos Kong]

vm_config_groups[] only contains part of the options which have
parameters, and all options which have no parameter aren't added
to vm_config_groups[]. Current query-command-line-options only
checks options from vm_config_groups[], so some options will
be lost.

We have macro in qemu-options.hx to generate a table that
contains all the options. This patch tries to query options
from the table.

Then we won't lose the legacy options that weren't added to
vm_config_groups[] (eg: -vnc, -smbios). The options that have
no parameter will also be returned (eg: -enable-fips)

Some options that have parameters have a NULL desc list, some
options don't have parameters, and "parameters" is mandatory
in the past. So we add a new field "unspecified-parameters" to
present if the option takes unspecified parameters.

This patch also fixes options to match their actual command-line
spelling rather than an alternate name associated with the
option table in use by the command.
