2020-10-06vppinfra: add heap header in front of dlmalloc spaceDamjan Marion1-0/+2
This patch adds smal header in front of dlmalloc space, and it stores some additional information about the heap.

2020-04-21vppinfra: bihash improvementsDave Barach1-0/+32
Template instances can allocate BIHASH_KVP_PER_PAGE data records tangent to the bucket, to remove a dependent read / prefetch.

2019-01-01Default huge page size to the regular page sizeDave Barach1-0/+6
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? Change-Id: I7f080f871c828cc4b44be13809495278fadbd717 Signed-off-by: Dave Barach <dave@barachs.net>
