2022-04-04vppinfra: make _vec_len() read-onlyDamjan Marion1-1/+1
Use of _vec_len() to set vector length breaks address sanitizer. Users should use vec_set_len(), vec_inc_len(), vec_dec_len () instead. Type: improvement Change-Id: I441ae948771eb21c23a61f3ff9163bdad74a2cb8 Signed-off-by: Damjan Marion <damarion@cisco.com>
2019-01-24perfmon plugin: 2-way parallel stat collectionDave Barach1-9/+2
As a FUD reduction measure, this patch implements 2-way parallel counter collection. Synthetic stat component counter pairs run at the same time. Running two counters (of any kind) at the same time naturally reduces the aggregate time required by an approximate factor-of-2, depending on whether an even or odd number of stats have been requested. I don't completely buy the argument that computing synthetic stats such as instructions-per-clock will be inaccurate if component counter values are collected sequentially. Given uniform traffic pattern, it must make no difference. As the collection interval increases, the difference between serial and parallel component counter collection will approach zero, see also the Central Limit theorem.

2018-06-13Stat segment / client: show run" works nowDave Barach1-1/+2
Seems to have minimal-to-zero performance consequences. Data appears accurate: result match the debug CLI output. Checked at low rates, 27 MPPS sprayed across two worker threads. Change-Id: I09ede5150b88a91547feeee448a2854997613004 Signed-off-by: Dave Barach <dave@barachs.net>
2018-01-09api: refactor vlibmemoryFlorin Coras1-55/+4
- separate client/server code for both memory and socket apis - separate memory api code from generic vlib api code - move unix_shared_memory_fifo to svm and rename to svm_fifo_t - overall declutter Change-Id: I90cdd98ff74d0787d58825b914b0f1eafcfa4dc2 Signed-off-by: Florin Coras <fcoras@cisco.com>
2017-03-09vlib_mains == 0 special cases be goneDave Barach1-10/+5
Clean up spurious binary API client link dependency on libvlib.so, which managed to hide behind vlib_mains == 0 checks reached by VLIB_xxx_FUNCTION macros. Change-Id: I5df1f8ab07dca1944250e643ccf06e60a8462325 Signed-off-by: Dave Barach <dave@barachs.net>
