However, to\nchange the subport level bandwidth, existing hierarchy needs to be\ndismantled and whole process of building hierarchy under subport nodes\nneeds to be repeated which might result in router downtime. Furthermore,\ndue to lack of dynamic configuration of the subport bandwidth profile\nconfiguration (shaper and Traffic class rates), the user application\nis unable to dynamically re-distribute the excess-bandwidth of one subport\namong other subports in the scheduler hierarchy. Therefore, it is also not\npossible to adjust the subport bandwidth profile in sync with dynamic\nchanges in pipe profiles of subscribers who want to consume higher\nbandwidth opportunistically.\n\nThis patch series implements dynamic configuration of the subport bandwidth\nprofile to overcome the runtime situation when group of subscribers are not\nusing the allotted bandwidth and dynamic bandwidth re-distribution is\nneeded the without making any structural changes in the hierarchy.\n\nThe implementation work includes refactoring the existing data structures\ndefined for port and subport level, new APIs for adding subport level\nbandwidth profiles that can be used in runtime.\n\nSavinay Dharmappa (9):\n sched: add support profile data structure\n sched: add subport profile table\n sched: add subport profile add and config api\n sched: update grinder credit and pipe config function\n example/qos_sched: add dynamic config of subport\n example/ip_pipeline: add dynamic config of subport\n drivers/softnic: add dynamic config of subport\n app/test_sched: add dynamic config of subport\n sched: remove the redundant code\n\n app/test/test_sched.c | 18 +-\n doc/guides/rel_notes/deprecation.rst | 6 -\n doc/guides/rel_notes/release_20_11.rst | 4 +\n drivers/net/softnic/rte_eth_softnic_internals.h | 9 +\n drivers/net/softnic/rte_eth_softnic_tm.c | 223 ++++++++---\n examples/ip_pipeline/cli.c | 14 +-\n examples/ip_pipeline/tmgr.c | 26 +-\n examples/ip_pipeline/tmgr.h | 3 +-\n examples/qos_sched/cfg_file.c | 151 ++++----\n examples/qos_sched/cfg_file.h | 4 +\n examples/qos_sched/init.c | 24 +-\n examples/qos_sched/main.h | 1 +\n examples/qos_sched/profile.cfg | 3 +\n lib/librte_sched/rte_sched.c | 479 +++++++++++++++++-------\n lib/librte_sched/rte_sched.h | 82 +++-\n lib/librte_sched/rte_sched_version.map | 2 +\n 16 files changed, 771 insertions(+), 278 deletions(-)", "diff": null, "prefixes": [ "v3", "0/9" ] }
