Subject: [dpdk-dev] [PATCH v2 0/5] change lpm route table from code to data
Date: Thu, 14 Jul 2016 17:06:17 +0100 [thread overview]
Message-ID: <1468512382-30412-1-git-send-email-bruce.richardson@intel.com> (raw)
In-Reply-To: <1465909410-4668-1-git-send-email-nikita@elyzion.net>
This patchset takes the existing lpm large routing table information and
converts it from a header file included at compile time to a resource linked
in. This improves things in two ways:
1. Improves DPDK build time
2. Removes approx 1 million lines of code from our LOC counts, as the header
file no longer counts as code, but more correctly as data.
Before and after approx code stats (with some additional patchsets applied)
are given below. Notice how the app folder has dropped from being the biggest
component with 6x the drivers code to second place with less code than the
drivers.
Future work is to repeat the same process for lpm6. Additional work for both
lpm and lpm6 is to remove the routing tables entirely and replace them with
auto-generated data that gives the roughly the same results. That would
shrink the overall size of DPDK releases, and is the desired end state.

This patchset is based directly on the original RFC submitted:
http://www.dpdk.org/ml/archives/dev/2016-May/038478.html.
Updates in this version compared to RFC:
* rebased on dpdk.org HEAD. The changes are now mostly to test_lpm_perf.c
rather than test_lpm.c
* removed use of strndupa() as suggest by Nikita Koslov
