[PATCH v3 0/6] qtests: Check accelerator available at runtime via QMP 'q

Subject: [PATCH v3 0/6] qtests: Check accelerator available at runtime via QMP 'query-accels'
Date: Thu, 15 Apr 2021 14:26:27 +0200

Hi,

This series aims at having accelerator-independent qtests
by querying a QEMU instance at runtime to check the list
of built-in accelerators.

First we add the 'query-accels' QMP command,
then we add the qtest_has_accel() method to libqtest,
finally we use this new method to allow running
bios-tables-test on KVM-only builds.

As a bonus we remove CONFIG_TCG in config_host, to avoid
building unnecessary objects depending on TCG.

Missing review:
- #4 qtest/qmp-cmd-test: Make test build-independent from accelerator
- #6 tests/meson: Only build softfloat objects if TCG is selected

Since v2:
- Addressed Eric & Paolo review comments

Since v1:
- kept over-engineered union (I don't how to do simple enum)
- dropped arm-cpu-features patches for now
- fixed typos (Eric)
- rename qtest_has_accel (Thomas)
- probe accel with machine none previous qtest (Paolo)
- iterate over QAPI enum (Markus)

Eric's suggestion of conditional QAPI didn't worked out,
as accelerator definitions are poisoned.

Please review,

Phil.
