Hi, we want to run DPDK on a NVIDIA Grace cpu. I tried building DPDK
v.23.11.1 with gcc 14.2 but got:
Message: Arm implementer: Arm
Message: Arm part number: 0xd4f
config/arm/meson.build:687:8: ERROR: Problem encountered: Unsupported
part number 0xd4f of implementer 0x41. Please add support for it or
use the generic (-Dplatform=generic) build.
I think part number 0xd4f is ARM Neoverse-V2.
I have seen some dpdk patch emails about support for Neoverse-V2 but I
don't know how to interpret them. Can anyone please tell me the dpdk
support status for this cpu, or tell me what we can do to workaround
this?
Best regards
David

IIUC, this was added in v24.03 in commit d007038c0121 ("config/arm:
add NVIDIA Grace CPU").

It is not back ported. You can use the latest release or back port the patch.
