Subject: [dpdk-dev] [PATCH v5 00/16] remove mbuf timestamp
Date: Tue,  3 Nov 2020 15:09:15 +0100
Message-ID: <20201103140931.488700-1-thomas@monjalon.net> (raw)
In-Reply-To: <20201029092751.3837177-1-thomas@monjalon.net>

The mbuf field timestamp was announced to be removed for three reasons:
  - a dynamic field already exist, used for Tx only
  - this field always used 8 bytes even if unneeded
  - this field is in the first half (cacheline) of mbuf

After this series, the dynamic field timestamp is used for both Rx and Tx
with separate dynamic flags to distinguish when the value is meaningful
without resetting the field during forwarding.

As a consequence, 8 bytes can be re-allocated to dynamic fields
in the first half of mbuf structure.
It is still open to change more the mbuf layout.

This mbuf layout change is important to allow adding more features
(consuming more dynamic fields) during the next year,
and can allow performance improvements with new usages in the first half.


v5:
- add a blank line between different kind of ARK variables
- move registration after octeontx2 VF config
- register also in otx2_nix_timesync_enable

v4:
- use local variable in nfb
- fix flag initialization
- remove useless blank line

v3:
- move ark variables declaration in a .h file 
- improve cache locality for octeontx2
- add comments about cache locality in commit logs
- add comment for unused flag offset 17
- add timestamp register functions
- replace lookup with register in drivers and apps
- remove register in ethdev

v2:
- remove optimization to register only once in ethdev
- fix error message in latencystats
- convert rxtx_callbacks macro to inline function
- increase dynamic fields space
- do not move pool field


Thomas Monjalon (16):
