Meeting summary
---------------

* CSIT (Maciek reporting)  (DaveBarach, 15:03:33)
  * CSIT-2001 tests and report done, except Skylake.  (mackonstan,
    15:03:52)
  * VPP v20.01 / CSIT-2001 Skylake NDR and PDR performance data to be
    published this week  (mackonstan, 15:04:04)
  * Poor NDR (zero drop) performance root caused to mgmt interface Linux
    en0 interrupts disturbing TRex operation on SuperMicro boards with
    Skylake processors.  (mackonstan, 15:04:40)
  * Was not happening before environment upgrades (BIOS, CPU ucode).
    (mackonstan, 15:04:55)
  * Those same interrupts are not present on the same SuperMicro
    motherboards equipped with Cascadelake processors.  (mackonstan,
    15:05:04)
  * In progress: Number of CSIT infrastructure and framework
    enhancements, gearing up to regular weekly NDR and PDR performance
    comparisons.  (mackonstan, 15:05:58)
  * CSIT in the cloud - added AWS c5n instances as another testbed
    topology, completed ip4 and ipsec performance dry run tests.
    (mackonstan, 15:08:05)
  * Mellanox tests - we are in the process of calibrating the MLX5 setup
    on both TRex side and SUT/VPP side, so pls take the current trending
    results with a pinch of salt.  (mackonstan, 15:08:49)

* host stack (Florin)  (DaveBarach, 15:09:41)
  * tcp supports connection scheduling, Improves high scale efficiency
    when sessions can't send  (DaveBarach, 15:10:21)
  * Same treatment applied to TLS  (DaveBarach, 15:10:37)
  * iperf + tls + ld_preload works (albeit not perfectly) one connectio
    > 12gb/sec  (DaveBarach, 15:11:28)
  * udp session pinning to workers, similar to TCP  (DaveBarach,
    15:12:02)
  * no longer supporting udp-c (connected) sessions  (DaveBarach,
    15:12:33)
  * vcl udp iperf test added to "make test"  (DaveBarach, 15:12:54)
  * iperf w/ 9K datagrams fills a 40g pipe  (DaveBarach, 15:13:12)
  * 1500 MTU -> fragmentation -> less than 20gbit  (DaveBarach,
    15:13:42)
  * "spring cleaning" effort - tcp features moved to separate files
    (DaveBarach, 15:14:15)
  * session api errors switched to session layer errors  (DaveBarach,
    15:14:32)
  * binary APIs now deprecated, as promised two releases ago
    (DaveBarach, 15:14:56)
  * all api messages use session queues, not binary api queues
    (DaveBarach, 15:15:12)

* Documentation (John, Ray)  (DaveBarach, 15:17:42)
  * multiple requests to add blog posts  (DaveBarach, 15:18:17)
  * adding csit / perf content, ask Maciek et al for review
    (DaveBarach, 15:18:18)

* Release Management (Andrew, Dave)  (DaveBarach, 15:18:19)
  * 20.05 about 4 weeks prior to api freeze  (DaveBarach, 15:18:19)
  * 20.01 planning 20.01.1 planned for after 19.08.X  (DaveBarach,
    15:18:20)
  * thanks Dave! a few clarifications 1) we now support tcp descheduling
    2) udp + fragmentation reaches less than 25Gbps  (florinc, 15:18:40)

* infra status (Dave W)  (DaveBarach, 15:20:49)
  * an issue last Friday due to CentOS timestamp issue  (DaveBarach,
    15:21:11)
  * no obvious reason, "went away by itself"  (DaveBarach, 15:21:23)

* planning / hoping to add 2x features to 20.05 (Ray K)  (DaveBarach,
  15:27:43)
  * async crypto / crypto-dev work  (DaveBarach, 15:27:52)
  * DDP (dynamic device personalization) to be added  (DaveBarach,
    15:28:22)
  * ACTION: Damjan to take a look at async crypto when he can
    (DaveBarach, 15:29:04)
  * DDP flow API to direct pkts to specific workers  (DaveBarach,
    15:29:55)
  * adding L2tpv3, ipsec  (DaveBarach, 15:30:06)
  * direct specific ipsec tunnels to specific cores  (DaveBarach,
    15:30:24)
  * direct specific l2tpv3 tunnels to specific cores  (DaveBarach,
    15:30:39)
  * will be a work in progress for a while  (DaveBarach, 15:31:07)
  * involves dpdk feature backport to dpdkd 20.02  (DaveBarach,
    15:31:58)
  * dpdk blast radius only in AVF driver  (DaveBarach, 15:33:18)
  * misc improvements, multiarch support, classifer perf tunes
    (DaveBarach, 15:34:56)
  * multiarch (damjan) 18.04 gnu assembler bug backport  (DaveBarach,
    15:35:54)
  * avx512 causes cpu power management glitches  (DaveBarach, 15:36:19)
  * on Skylake, Cascade lake  (DaveBarach, 15:37:04)
