This can be used to run tests multple times, with e.g. differing
QEMU settings, by adding something like this to the FATE configuration
file:
target_exec="qemu-aarch64-static"
fate_targets="fate-checkasm fate-cpu"
fate_environments="sve128 sve256 sve512"
sve128_env="QEMU_CPU=max,sve128=on"
sve256_env="QEMU_CPU=max,sve256=on"
sve512_env="QEMU_CPU=max,sve512=on"
I'm fine with that, but for the sake of generality, shouldn't rather the
entire target_exec prefix be indirected? Some runners may want to use
command line flags rather than environment variables.
Yes - that's also doable. One can e.g. do this:
---
target_exec="qemu-aarch64-static -cpu \$(MY_CPU)"
fate_targets="fate-checkasm fate-cpu"
fate_environments="sve128 sve256 sve512"
sve128_env="MY_CPU=max,sve128=on"
sve256_env="MY_CPU=max,sve256=on"
sve512_env="MY_CPU=max,sve512=on"
---
That way, one can also make the whole target_exec be e.g. \$(EXEC_CMD) and
set the full command via the individual envs. It's not quite as comfortable,
but should be doable and allow fully generic setups.
If this sounds reasonable enough, I would go ahead and land this, together
with
https://patchwork.ffmpeg.org/project/ffmpeg/patch/20231127123118.3622784-1-mar...@martin.st/.
I guess this feature should have some documentation as well - I can draft
up a v2 with docs before going ahead with it, if the feature overall looks
acceptable.
