From 1b2143aa681ae2412da98a076e46c477fafb8588 Mon Sep 17 00:00:00 2001 From: Pavan Nikhilesh Date: Wed, 30 Oct 2019 21:56:43 +0530 Subject: [PATCH] examples/l2fwd-event: add infra for eventdev Add infra to select event device as a mode to process packets through command line arguments. Also, allow the user to select the schedule type to be RTE_SCHED_TYPE_ORDERED, RTE_SCHED_TYPE_ATOMIC or RTE_SCHED_TYPE_PARALLEL. Usage: `--mode="eventdev"` or `--mode="poll"` `--eventq-sched="ordered"`, `--eventq-sched="atomic"` or `--event-sched=parallel` Signed-off-by: Sunil Kumar Kori Signed-off-by: Pavan Nikhilesh Acked-by: Nipun Gupta Acked-by: Jerin Jacob --- examples/l2fwd-event/Makefile | 1 + examples/l2fwd-event/l2fwd_common.h | 4 +++ examples/l2fwd-event/l2fwd_event.c | 34 +++++++++++++++++++ examples/l2fwd-event/l2fwd_event.h | 21 ++++++++++++ examples/l2fwd-event/main.c | 52 +++++++++++++++++++++++++++-- examples/l2fwd-event/meson.build | 1 + 6 files changed, 111 insertions(+), 2 deletions(-) create mode 100644 examples/l2fwd-event/l2fwd_event.c create mode 100644 examples/l2fwd-event/l2fwd_event.h diff --git a/examples/l2fwd-event/Makefile b/examples/l2fwd-event/Makefile index 73f02dd3bd..08ba1835db 100644 --- a/examples/l2fwd-event/Makefile +++ b/examples/l2fwd-event/Makefile @@ -8,6 +8,7 @@ APP = l2fwd-event # all source are stored in SRCS-y SRCS-y := main.c SRCS-y += l2fwd_poll.c +SRCS-y += l2fwd_event.c SRCS-y += l2fwd_common.c # Build using pkg-config variables if possible diff --git a/examples/l2fwd-event/l2fwd_common.h b/examples/l2fwd-event/l2fwd_common.h index 7b74f92b3f..a4e17ab97f 100644 --- a/examples/l2fwd-event/l2fwd_common.h +++ b/examples/l2fwd-event/l2fwd_common.h @@ -65,6 +65,8 @@ struct l2fwd_port_statistics { struct l2fwd_resources { volatile uint8_t force_quit;
