From 703faabf2d44d245fe1dd0b75f1736bf6114a557 Mon Sep 17 00:00:00 2001 From: Konstantin Ananyev Date: Thu, 27 Jun 2019 19:28:26 +0100 Subject: v6: memtank introduction For analogy with mempool, named this structure memtank. Same a s mempool it allows to alloc/free objects of fixed size in a lightweight manner (not as lightweight as mempool, but hopefully close enough). The whole idea is that alloc/free is used at fast-path and don't allocate/free more than *min_free* objects at one call. So for majority of cases our fast-path alloc/free should be lightweight (LIFO enqueue/dequeue operations). Also user will need to call grow/shrink periodically (ideally from the slow-path) to make sure there is enough free objects in the tank. Internally it is just a simple LIFO for up to *max_free* objects plus a list of memory buffers (memchunk) from where these objects were allocated. v1 -> v2 - Added UT - Fixed few bugs v2 -> v3 - extend UT with more parameters v3 -> v4 - add object alignement as parameter for memtank_create - extend UT with more parameters - added memtank dump routine v4 -> v5 - fixed few bugs inside memtank lib - extend UT with: - new test case - new command-line options: '-s ', '-m ' v5 -> v6 - extend memtank dump to collect/display extra information - make memtank dump routine MT safe - add memtank sanity check function - add proper comments for pubic API Signed-off-by: Konstantin Ananyev Change-Id: I8939772577f5d9e293088eaa9a9fe316c3fe8f87 --- lib/Makefile | 1 + 1 file changed, 1 insertion(+) (limited to 'lib/Makefile') diff --git a/lib/Makefile b/lib/Makefile index 6317af9..8d61a08 100644 --- a/lib/Makefile +++ b/lib/Makefile @@ -24,6 +24,7 @@ include $(RTE_SDK)/mk/rte.vars.mk DIRS-y += libtle_misc DIRS-y += libtle_dring DIRS-y += libtle_timer +DIRS-y += libtle_memtank DIRS-y += libtle_l4p include $(TLDK_ROOT)/mk/tle.subdir.mk -- cgit 1.2.3-korg
