This patch implements the changes proposed in the deprecation notes [1][2].
librte_mbuf changes: The mbuf->hash.sched field is updated to support generic definition in line with the ethdev traffic manager and meter APIs. The new generic format contains: queue ID, traffic class, color. Added public APIs to set and get these new fields to and from mbuf. librte_sched changes: In addtion, following API functions of the sched library have been modified with an additional parameter of type struct rte_sched_port to accommodate the changes made to mbuf sched field. (i)rte_sched_port_pkt_write() (ii) rte_sched_port_pkt_read_tree_path() librte_pipeline, qos_sched UT, qos_sched app are updated to make use of new changes. Also mbuf->hash.txadapter has been added for eventdev txq, rte_event_eth_tx_adapter_txq_set and rte_event_eth_tx_adapter_txq_get() are updated to use mbuf->hash.txadapter.txq. doc: Release notes updated. Removed deprecation notice for mbuf->hash.sched and sched API.

Moved rte_mbuf_sched inside the rte_mbuf struct. Added missing empty line in doxygen comments of sched set and get functions. v6: added scheduler comment v5: Removed librte_meter from librte_mbuf dependency list. Changed the mbuf set/get functions to use uint8_t for color. v4: converted mbuf->hash.sched as instantiation of rte_mbuf_sched. v3: addressed review comments given in the below link. http://patches.dpdk.org/patch/48587/ Updated library ABI versioning in meson build. --- --- doc/guides/rel_notes/deprecation.rst | 10 -- doc/guides/rel_notes/release_19_02.rst | 4 +- examples/qos_sched/app_thread.c | 7 +- examples/qos_sched/main.c | 1 + .../rte_event_eth_tx_adapter.h | 18 ++- lib/librte_mbuf/Makefile | 2 +- lib/librte_mbuf/meson.build | 2 +- lib/librte_mbuf/rte_mbuf.h | 119 +++++++++++++++++- lib/librte_pipeline/rte_table_action.c | 44 +++---- lib/librte_sched/Makefile | 2 +- lib/librte_sched/meson.build | 1 + lib/librte_sched/rte_sched.c | 90 ++++++------- lib/librte_sched/rte_sched.h | 10 +- test/test/test_sched.c | 9 +- 14 files changed, 197 insertions(+), 122 deletions(-) diff --git a/doc/guides/rel_notes/deprecation.rst b/doc/guides/rel_notes/deprecation.rst index ac7fb29a7..ec80dcc7b 100644 --- a/doc/guides/rel_notes/deprecation.rst +++ b/doc/guides/rel_notes/deprecation.rst @@ -49,16 +49,6 @@ Deprecation Notices structure would be made internal (or removed if all dependencies are cleared) in future releases. -* mbuf: The opaque ``mbuf->hash.sched`` field will be updated to support generic - definition in line with the ethdev TM and MTR APIs.
