This ABI change was announced in the\n20.08 release notes [1]. This patch was initially part of\nthe V1 DLB PMD patchset.\n\nThe DLB hardware does not conform exactly to the eventdev interface.\n1) It has a limit on the number of queues that may be linked to a port.\n2) Some ports are further restricted to a maximum of 1 linked queue.\n3) It does not (currently) have the ability to carry the flow_id as part\nof the event (QE) payload.\n\nDue to the above, we would like to propose the following enhancements.\n\n1) Add new fields to the rte_event_dev_info struct. These fields allow\nthe device to advertise its capabilities so that applications can take\nthe appropriate actions based on those capabilities.\n\n2) Add a new field to the rte_event_dev_config struct. This field allows\nthe application to specify how many of its ports are limited to a single\nlink, or will be used in single link mode.\n\n3) Replace the dedicated implicit_release_disabled field with a bit field\nof explicit port capabilities. The implicit_release_disable functionality\nis assigned to one bit, and a port-is-single-link-only attribute is\nassigned to another, with the remaining bits available for future\nassignment.\n\nNote that it was requested that we split this app/test\nchanges out from the eventdev ABI changes. As a result,\nneither of these patches will bujild without the other\nalso being applied.\n\n[1] http://mails.dpdk.org/archives/dev/2020-August/177261.html \n\nTimothy McDaniel (2):\n eventdev: implement ABI change\n eventdev: update app and examples for new eventdev ABI\n\n app/test-eventdev/evt_common.h | 11 ++++\n app/test-eventdev/test_order_atq.c | 30 +++++++---\n app/test-eventdev/test_order_common.c | 1 +\n app/test-eventdev/test_order_queue.c | 31 +++++++---\n app/test/test_eventdev.c | 4 +-\n drivers/event/dpaa/dpaa_eventdev.c | 3 +-\n drivers/event/dpaa2/dpaa2_eventdev.c | 5 +-\n drivers/event/dsw/dsw_evdev.c | 3 +-\n drivers/event/octeontx/ssovf_evdev.c | 5 +-\n drivers/event/octeontx2/otx2_evdev.c | 3 +-\n drivers/event/opdl/opdl_evdev.c | 3 +-\n drivers/event/skeleton/skeleton_eventdev.c | 5 +-\n drivers/event/sw/sw_evdev.c | 8 ++-\n drivers/event/sw/sw_evdev_selftest.c | 6 +-\n .../eventdev_pipeline/pipeline_worker_generic.c | 6 +-\n examples/eventdev_pipeline/pipeline_worker_tx.c | 1 +\n examples/l2fwd-event/l2fwd_event_generic.c | 7 ++-\n examples/l2fwd-event/l2fwd_event_internal_port.c | 6 +-\n examples/l3fwd/l3fwd_event_generic.c | 7 ++-\n examples/l3fwd/l3fwd_event_internal_port.c | 6 +-\n lib/librte_eventdev/rte_event_eth_tx_adapter.c | 2 +-\n lib/librte_eventdev/rte_eventdev.c | 66 +++++++++++++++++++---\n lib/librte_eventdev/rte_eventdev.h | 51 ++++++++++++++---\n lib/librte_eventdev/rte_eventdev_pmd_pci.h | 1 -\n lib/librte_eventdev/rte_eventdev_trace.h | 7 ++-\n lib/librte_eventdev/rte_eventdev_version.map | 4 +-\n 26 files changed, 218 insertions(+), 64 deletions(-)" }
