The problem is inconsistency in performance on different Arm platforms.

We had decided that each platform needs to enable it after some testing.

Then it sounds like it does indeed need to be a build option. Does it need to
be added to the meson_options.txt, or can it just be specified in cross-files
and optionally via c_args?

Add it to the meson_options.txt is good as the option will be clearly exposed.
My concern is more options (e.g. RTE_ARCH_ARM64_MEMCPY) need to be added in.
Will the options bloat meson_options.txt?

That bloat would indeed become a concern. We may need to look at more use
of auto-detection and cross files for such options.

Ruifeng,
