From 036343b8b15389df52db12ff62da0133a8f030fd Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Tue, 1 Jan 2019 09:45:08 -0500 Subject: [PATCH] Default huge page size to the regular page size With this simple tweak, vpp is OK for "make test" or non-dpdk driver operation over a kernel which doesn't support hugepages at all. Tested on a Raspberry-pi 3B+ running the Ubuntu 18.04 64-bit server beta image. It's amazing that such a minimal system will not only self-compile vpp, but also run the unit tests. It's slow, but what do you expect for that amount of money?
