This patch set introduces a new API <rte_lcore_var.h> for static
per-lcore id data allocation.
Please refer to the <rte_lcore_var.h> API documentation for both a
rationale for this new API, and a comparison to the alternatives
available.
The question on how to best allocate static per-lcore memory has been
up several times on the dev mailing list, for example in the thread on
"random: use per lcore state" RFC by Stephen Hemminger.
Lcore variables are surely not the answer to all your per-lcore-data
needs, since it only allows for more-or-less static allocation. In the
author's opinion, it does however provide a reasonably simple and
clean and seemingly very much performant solution to a real problem.
Mattias Rönnblom (7):
eal: add static per-lcore memory allocation facility
eal: add lcore variable functional tests
eal: add lcore variable performance test
random: keep PRNG state in lcore variable
power: keep per-lcore state in lcore variable
service: keep per-lcore state in lcore variable
eal: keep per-lcore power intrinsics state in lcore variable
Still too wordy, would you mind if I have a try and summarizing and
running the text through an editor tool?
I think you need to be a little more wordy here. What text? The cover
text? That won't survive anyway.
