Dear all,

I am currently working on VPP v17.07.

I would like to do some measurement and change the size of the VLIB_FRAME_SIZE,
defined in

VPP_ROOT/src/vlib/node.h.

However, I face an issue similar to the post
(https://lists.fd.io/pipermail/vpp-dev/2017-March/004361.html).

More in detail, when I set up the VLIB_FRAME_SIZE to 128 at run time I
got the following error.


0: /root/vpp/build-data/../src/vlib/main.c:483 (vlib_put_next_frame)
assertion `n_vectors_left <= VLIB_FRAME_SIZE' fails



Whereas, when I set up the VLIB_FRAME_SIZE to 512 at run time I got the
following error.

 /root/vpp/build-data/../src/vlib/physmem.h:96 (vlib_physmem_at_offset)
assertion `offset < pm->virtual.size' fails



I tried both with the debug version and the build-release. Moreover when I
compile I do:

make wipe-release

make build-release

Is there something else that I should do in order to let VPP working with
other VLIB_FRAME_SIZE values?

Best regards,
Alessio
