Re: [PATCH 2/2] ASoC: topology: Add explicit build option

On Wed, 12 Jul 2023 at 23:40, Mark Brown broonie@kernel.org wrote:

The default KUnit build options are not supposed to enable any subsystems that were not already enabled but the topology code is a library which is generally selected by drivers that want to use it. Since KUnit is frequently run in virtual environments with minimal driver support this makes it difficult to enable the toplogy tests so provide an explicit Kconfig option which can be directly enabled when using KUnit, and also include this in the KUnit all_tests.config.

Thanks a bunch for this: the topology tests have always been some of the most annoying to run, and this makes it so much easier.

That being said, it does still break when run with ARCH=um (see the response to patch 1/2), so we might need to remove it from all_tests.config or make some other changes.

Having the CONFIG_SND_SOC_TOPOLOGY_BUILD option is definitely much better, regardless of whether it's default or not.
