Subject: [PATCH 1/2] config/arm: Do not require processor information
DPDK can be built even without exact processor information for x86
and ppc so allow to build for Arm even if we don't know the targeted processor
is
unknown.
Hi Akihiko,
The design idea was to require an explicit generic build.
Default/native build doesn't fall back to generic build when SoC info is not on
the list.
So the user has less chance to generate a suboptimal binary by accident.
Hi,
It is true that the suboptimal binary can result, but the rationale here is
that we
tolerate that for x86 and ppc so it should not really matter for Arm too. On
x86 and ppc
you don't need to modify meson.build just to run dts on a development machine.
What modification do you need for a development machine?
I suppose "meson setup build -Dplatform=generic" will generate a binary that
can run
on your development machine.
I didn't describe the situation well. I use DPDK Test Suite for testing
and it determines what flags to be passed to Meson. You need to modify
DPDK's meson.build or DTS to get it built.

Akihiko Odaki
