2022-05-03feat(astf): Support framesizes for ASTFVratko Polak1-20/+22
- No support for IMIX. + Fix a bad bug in padding (most ASTF profiles had wrong frame sizes). + Fix a big typo in TCP PPS profiles (s->c was not data, just RST). + Control transaction size via ASTF_N_DATA_FRAMES env variable. - Default value 5 leads to transactions smaller than before. + It ensures transaction is one burst (per direction) even for jumbo. + Edit autogen to set supported frame sizes based on suite id. + Both TCP and UDP use the same values: + 64B for CPS (exact for UDP, nominal for TCP). + 100B, 1518B and 9000B for TPUT and PPS. - TCP TPUT achievable minimum is 70B. + Used 100B to leave room for possible IPv6 ASTF tests. + Separate function for code reused by vpp and trex tests. - I do not really like the new "copy and edit" approach added here. + But it is a quick edit, better autogen refactor is low priority. + Consider both established and transitory sessions as valid. - Mostly for compatibility with 2202 behavior and to avoid ramp-ups. - Assuming both session states have similar enough VPP CPU overhead. + Added a TODO to investigate and maybe reconsider later. + Update the state timeout value to 240s. + That is the default for TCP (for transitory state). - UDP could keep using 300s. + But I prefer UDP and TCP to behave as similarly as possible. + Use TRex tunables to get the exact frame size (for data packets). - It is not clear why the recipe for MSS has to be this complicated. + Move code away from profile init, as frame size is not known there. + Change internal profile API, so values related to MSS are passed. + Lower ramp-up rate for TCP TPUT tests. + Because without lower rate, jumbo fails on packet loss in ramp-up. + UDP TPUT ramp-up rate also lowered (just to keep suites more similar). + Distinguish one-direction and aggregated average frame size. + Update keyword documentation where the distiction matters. + One-direction is needed for turning bandwidth limit to TPS limit. + Aggregated is needed for correct NDRPDR bandwidth result value. - TCP TPUT will always be few percent below bidirectional maximum. + That is unavoidable, as one direction sends more control packets. + Add runtime consistency checks so future refactors are safer. + Fail if padding requested would be negative. + Fail if suite claims unexpected values for packets per transaction. + Edit the 4 types of ASTF profiles to keep them similar to each other. + Move UDP TPUT limit value from a field back to direct argument. + Stop pretending first UDP packet is not data. + Apply small improvements where convenient. + Replace "aggregate" with "aggregated" where possible. + To lower probability of any future typos in variable names. + Avoid calling Set Numeric Frame Sizes twice. + Code formatting, keyword documentation, code comments, ... + Add TODOs for less important code quality improvements. - Postpone updating of methodology pages to a subsequent change.

2021-01-12License: Wrap GPL block to 80 charactersVratko Polak1-2/+3
The original license block was adapted from https://wiki.fd.io/view/TSC/Proposed_Header_Python_Test_Scripts resulting in a line longer than 80 chars, but those are reported (although not blocked) by tox verify job. As the text from wiki was not used in verbatim (it uses c-style comment block), minor formatting change like this should not be a big deal. + Bump copyright year.

2020-08-24T-Rex: 2.82, core pin, 8 workerspmikus1-1/+1
+ Bump T-Rex version. We need new features for ASTF test. + Apply core pining. Results in a more stable performance. + Tweak the number of T-Rex workers. + We need an even value to achieve ymmetric performance with pinning. + Value 8 was selected as a best compromise. This is a combination of 3 commits. This is the 1st commit message: T-Rex: 2.82 This is the commit message #2: Change Trex to CORE_MASK_PIN mode to improve performance https://trex-tgn.cisco.com/trex/doc/trex_stateless.html#_core_masking_per_interface Above link have below explaination, "When the profile is symmetric, performance can be improved by pinning half of the cores to port 0, and half of the cores to port 1, thus avoiding cache trashing and bouncing." The reason to change this is that to run CSIT with 100G NIC often failed with "TRex stateless runtime error timeout", it caused by Trex can not send enough traffic within the fixed duration. by change to CORE_MASK_PIN mode fix the issue. Not editing ASTF, as that supports different options. This is the commit message #3: Experiment: Vary number of TRex workers With CORE_MASK_PIN, we can get more predictable time distribution. Decided to use 8 workers, that gives good results both for high end (RDMA-core l2patch) and low end (vhost) tests.
