This is justified by\nthe fact that all the high priority TCs are fully provisioned (small to\nmedium traffic rates), while most of the traffic fits into the BE class,\nwhich is typically oversubscribed.\n\nFurthermore, this change allows to use less than 16 queues per pipe when\nnot all the 16 queues are needed. Therefore, no memory will be allocated\nto the queues that are not needed.\n\nv5:\n- fix traffic class and queue mapping in api function\n- remove n_be_queues parameter from internal pipe profile and pipe struct\n- replace int multiplication in grinder_schedule func with bitwise & operation\n- remove TC_OV logic flag from all the configuration/initialization code\n- fix traffic qsize per traffic class instead of individual queue of the pipe\n\nv4:\n- fix build errors\n- fix checkpatch errors\n\nv3:\n- remove code related to subport level configuration of the pipe \n- remove tc oversubscription flag from struct rte_sched_pipe_params\n- replace RTE_SCHED_PIPE_PROFILES_PER_PORT with port param field\n\nv2:\n- fix bug in subport parameters check\n- remove redundant RTE_SCHED_SUBPORT_PER_PORT macro\n- fix bug in grinder_scheduler function\n- improve doxygen comments \n- add error log information\n\nJasvinder Singh (11):\n sched: remove wrr from strict priority tc queues\n sched: add config flexibility to tc queue sizes\n sched: add max pipe profiles config in run time\n sched: rename tc3 params to best-effort tc\n sched: improve error log messages\n sched: improve doxygen comments\n net/softnic: add config flexibility to softnic tm\n test_sched: modify tests for config flexibility\n examples/ip_pipeline: add config flexibility to tm function\n examples/qos_sched: add tc and queue config flexibility\n sched: remove redundant macros\n\n app/test/test_sched.c | 15 +-\n doc/guides/rel_notes/release_19_08.rst | 10 +-\n drivers/net/softnic/rte_eth_softnic.c | 98 ++\n drivers/net/softnic/rte_eth_softnic_cli.c | 448 +++++++++-\n .../net/softnic/rte_eth_softnic_internals.h | 6 +-\n drivers/net/softnic/rte_eth_softnic_tm.c | 121 ++-\n examples/ip_pipeline/cli.c | 43 +-\n examples/ip_pipeline/tmgr.h | 4 +-\n examples/qos_sched/app_thread.c | 11 +-\n examples/qos_sched/cfg_file.c | 130 ++-\n examples/qos_sched/init.c | 65 +-\n examples/qos_sched/main.h | 4 +\n examples/qos_sched/profile.cfg | 67 +-\n examples/qos_sched/profile_ov.cfg | 54 +-\n examples/qos_sched/stats.c | 517 ++++++-----\n lib/librte_pipeline/rte_table_action.c | 1 -\n lib/librte_pipeline/rte_table_action.h | 4 +-\n lib/librte_sched/Makefile | 2 +-\n lib/librte_sched/meson.build | 2 +-\n lib/librte_sched/rte_sched.c | 835 +++++++++++-------\n lib/librte_sched/rte_sched.h | 183 ++--\n 21 files changed, 1847 insertions(+), 773 deletions(-)", "diff": null, "prefixes": [ "v5", "00/11" ] }
