Notice there is also an option called "ratep" which can be used for setting the packet rate per sec. In the pktgen.c code, it will use the "delay" variable. > Signed-off-by: Igor Russkikh <irusskikh@marvell.com> > --- > samples/pktgen/parameters.sh | 10 +++++++++- > samples/pktgen/pktgen_bench_xmit_mode_netif_receive.sh | 3 --- > samples/pktgen/pktgen_bench_xmit_mode_queue_xmit.sh | 3 --- > samples/pktgen/pktgen_sample01_simple.sh | 3 --- > samples/pktgen/pktgen_sample02_multiqueue.sh | 1 - > samples/pktgen/pktgen_sample03_burst_single_flow.sh | 3 --- > samples/pktgen/pktgen_sample04_many_flows.sh | 3 --- > samples/pktgen/pktgen_sample05_flow_per_thread.sh | 3 --- > .../pktgen_sample06_numa_awared_queue_irq_affinity.sh | 1 - > 9 files changed, 9 insertions(+), 21 deletions(-) > > diff --git a/samples/pktgen/parameters.sh b/samples/pktgen/parameters.sh > index ff0ed474fee9..70cc2878d479 100644 > --- a/samples/pktgen/parameters.sh > +++ b/samples/pktgen/parameters.sh > @@ -19,12 +19,13 @@ function usage() { > echo " -v : (\$VERBOSE) verbose" > echo " -x : (\$DEBUG) debug" > echo " -6 : (\$IP6) IPv6" > + echo " -w : (\$DELAY) Tx Delay value (us)" I think the resolution is in nanosec. > echo "" > } > > ## --- Parse command line arguments / parameters --- > ## echo "Commandline options:" > -while getopts "s:i:d:m:p:f:t:c:n:b:vxh6" option; do > +while getopts "s:i:d:m:p:f:t:c:n:b:w:vxh6" option; do > case $option in > i) # interface > export DEV=$OPTARG > @@ -66,6 +67,10 @@ while getopts "s:i:d:m:p:f:t:c:n:b:vxh6" option; do > export BURST=$OPTARG > info "SKB bursting: BURST=$BURST" > ;; > + w) > + export DELAY=$OPTARG > + info "DELAY=$DELAY" > + ;; > v) > export VERBOSE=yes > info "Verbose mode: VERBOSE=$VERBOSE" > @@ -100,6 +105,9 @@ if [ -z "$THREADS" ]; then > export THREADS=1 > fi > > +# default DELAY > +[ -z "$DELAY" ] && export DELAY=0 # Zero means max speed > + Nice this allow us to remove some lines in the other scripts. As all script have line: pg_set $dev "delay $DELAY" I am the original author of the scripts, so I'm allowed to say that doing this was actually kind of pointless, because the default delay value is already zero. Although, you now took advantage of this sillyness ;-) If we want to use "ratep" instead, then we actually need to change all those lines, because pg_set "ratep" and "delay" share the same setting in the kernel. > export L_THREAD=$(( THREADS + F_THREAD - 1 )) > > if [ -z "$DEV" ]; then > diff --git a/samples/pktgen/pktgen_bench_xmit_mode_netif_receive.sh b/samples/pktgen/pktgen_bench_xmit_mode_netif_receive.sh > index 1b6204125d2d..30a610b541ad 100755 > --- a/samples/pktgen/pktgen_bench_xmit_mode_netif_receive.sh > +++ b/samples/pktgen/pktgen_bench_xmit_mode_netif_receive.sh > @@ -50,9 +50,6 @@ if [ -n "$DST_PORT" ]; then > validate_ports $UDP_DST_MIN $UDP_DST_MAX > fi > > -# Base Config > -DELAY="0" # Zero means max speed > - > # General cleanup everything since last run > pg_ctrl "reset" > > diff --git a/samples/pktgen/pktgen_bench_xmit_mode_queue_xmit.sh b/samples/pktgen/pktgen_bench_xmit_mode_queue_xmit.sh > index e607cb369b20..a6195bd77532 100755 > --- a/samples/pktgen/pktgen_bench_xmit_mode_queue_xmit.sh > +++ b/samples/pktgen/pktgen_bench_xmit_mode_queue_xmit.sh > @@ -33,9 +33,6 @@ if [ -n "$DST_PORT" ]; then > validate_ports $UDP_DST_MIN $UDP_DST_MAX > fi > > -# Base Config > -DELAY="0" # Zero means max speed > - > # General cleanup everything since last run > pg_ctrl "reset" > > diff --git a/samples/pktgen/pktgen_sample01_simple.sh b/samples/pktgen/pktgen_sample01_simple.sh > index a4e250b45dce..c2ad1fa32d3f 100755 > --- a/samples/pktgen/pktgen_sample01_simple.sh > +++ b/samples/pktgen/pktgen_sample01_simple.sh > @@ -31,9 +31,6 @@ if [ -n "$DST_PORT" ]; then > validate_ports $UDP_DST_MIN $UDP_DST_MAX > fi > > -# Base Config > -DELAY="0" # Zero means max speed > - > # Flow variation random source port between min and max > UDP_SRC_MIN=9 > UDP_SRC_MAX=109 > diff --git a/samples/pktgen/pktgen_sample02_multiqueue.sh b/samples/pktgen/pktgen_sample02_multiqueue.sh > index cb2495fcdc60..49e1e81a2945 100755 > --- a/samples/pktgen/pktgen_sample02_multiqueue.sh > +++ b/samples/pktgen/pktgen_sample02_multiqueue.sh > @@ -17,7 +17,6 @@ source ${basedir}/parameters.sh > [ -z "$COUNT" ] && COUNT="100000" # Zero means indefinitely > > # Base Config > -DELAY="0" # Zero means max speed > [ -z "$CLONE_SKB" ] && CLONE_SKB="0" > > # Flow variation random source port between min and max > diff --git a/samples/pktgen/pktgen_sample03_burst_single_flow.sh b/samples/pktgen/pktgen_sample03_burst_single_flow.sh > index fff50765a5aa..f9b67affb567 100755 > --- a/samples/pktgen/pktgen_sample03_burst_single_flow.sh > +++ b/samples/pktgen/pktgen_sample03_burst_single_flow.sh > @@ -42,9 +42,6 @@ if [ -n "$DST_PORT" ]; then > validate_ports $UDP_DST_MIN $UDP_DST_MAX > fi > > -# Base Config > -DELAY="0" # Zero means max speed > - > # General cleanup everything since last run > pg_ctrl "reset" > [...]
