2018-02-08Minimize bihash memory consumptionDave Barach1-9/+46
Reference-count the number of entries in each bucket. If the reference count goes to zero, free the backing store. Add long-term churn-testing to test_bihash_template.c, thanks to Andrew Yourtchenko for the initial implementation.

2017-08-31Fix BIHASH_KVP_CACHE_SIZE == 0 caseDave Barach1-1/+13
Setting the bucket-level LRU cache size to zero removes the bucket-level LRU cache code. Change-Id: Idf2e63d0d508675e957366515863766f79a3479c Signed-off-by: Dave Barach <dbarach@cisco.com>

2017-07-19Add a bihash prefetchable bucket-level cacheDave Barach1-8/+70
According to Maciek, the easiest way to leverage the csit "performance trend" job is to actually merge the patch once verified. Manual testing indicates that the patch improves l2 path performance. Other use-cases are TBD. It's possible that we'll need to back out the patch depending on what happens.

The Wmaybe-uninitialized is the new error included with Wall. This patch addresses the warning and fixes it. Change-Id: I8fdf9ff2d236c46b717024a14874fbbbad8af303 Signed-off-by: Marco Varlese <marco.varlese@suse.com>
2017-06-02Fix mac_age process crash in multi-threaded environmentSteve Shin1-2/+1
VPP crash is observed when MAC aging is enabled with multi-threaded mode. If a thread other-than-zero expands the working_copies vector, working_copy_lengths should be initialized with vec_validate_init_empty(..., -1) to fill -1 across lower-numbered working_copy_lengths vector element.

2017-05-18VPP-847: improve bihash template memory allocator performanceDave Barach1-27/+43
Particularly in the DCLIB_VEC64=1 case, using vectors vs. raw clib_mem_alloc'ed memory causes abysmal memory allocator performance. Change-Id: I07a4dec0cd69ca357445385e2671cdf23c59b95d Signed-off-by: Dave Barach <dave@barachs.net>
