Subject: [dpdk-dev] [PATCH v4 0/3] mempool: user-owned mempool caches
Date: Mon, 27 Jun 2016 17:50:34 +0200 [thread overview]
Message-ID: <1467042637-22907-1-git-send-email-olivier.matz@6wind.com> (raw)
In-Reply-To: <1466074939-29863-1-git-send-email-l@nofutznetworks.com>
Updated version of the user-owned cache patchset. It applies on top of
the latest external mempool manager patches from David Hunt [1].
[1] http://dpdk.org/ml/archives/dev/2016-June/041479.html
v4 changes:
* Fix compilation with shared libraries
* Add a GOTO_ERR() macro to factorize code in test_mempool.c
* Change title of patch 2 to conform to check-git-log.sh
v3 changes:
* Deprecate specific mempool API calls instead of removing them.
* Split deprecation into a separate commit to limit noise.
* Fix cache flush by setting cache->len = 0 and make it inline.
* Remove cache->size == 0 checks and ensure size != 0 at creation.
* Fix tests to check if cache creation succeeded.
* Fix tests to free allocated resources on error.
The mempool cache is only available to EAL threads as a per-lcore
resource. Change this so that the user can create and provide their own
cache on mempool get and put operations. This works with non-EAL threads
too.
Also, deprecate the explicit {mp,sp}_put and {mc,sc}_get calls and
re-route them through the new generic calls. Minor cleanup to pass the
mempool bit flags instead of using specific is_mp and is_mc. The old
cache-oblivious API calls use the per-lcore default local cache. The
mempool and mempool_perf tests are also updated to handle the
user-owned cache case.
Introduced API calls:
rte_mempool_cache_create(size, socket_id)
rte_mempool_cache_free(cache)
rte_mempool_cache_flush(cache, mp)
rte_mempool_default_cache(mp, lcore_id)
rte_mempool_generic_put(mp, obj_table, n, cache, flags)
rte_mempool_generic_get(mp, obj_table, n, cache, flags)
Deprecated API calls:
rte_mempool_mp_put_bulk(mp, obj_table, n)
rte_mempool_sp_put_bulk(mp, obj_table, n)
rte_mempool_mp_put(mp, obj)
rte_mempool_sp_put(mp, obj)
rte_mempool_mc_get_bulk(mp, obj_table, n)
rte_mempool_sc_get_bulk(mp, obj_table, n)
rte_mempool_mc_get(mp, obj_p)
rte_mempool_sc_get(mp, obj_p)
Lazaros Koromilas (3):
mempool: deprecate specific get/put functions
mempool: use bit flags to set multi consumers or producers
mempool: allow for user-owned mempool caches
