44. Short-lived Application Tests¶
This feature is to reduce application start up time, and when exit, do more clean up so that it could be re-run many times.
44.1. Prerequisites¶
To test this feature, need to using linux time and start testpmd by: create and mount hugepage, must create more hugepages so that could measure time more obviously:
# echo 8192 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
# mount -t hugetlbfs hugetlbfs /mnt/huge
Bind nic to DPDK:
./tools/dpdk_nic_bind.py -b igb_uio xxxx:xx:xx.x
Start testpmd using time:
# echo quit | time ./testpmd -c 0x3 -n 4 -- -i
44.2. Test Case 1: basic fwd testing¶
Start testpmd:
./testpmd -c 0x3 -n 4 -- -i
Set fwd mac
Send packet from pkg
Check all packets could be fwd back
44.3. Test Case 2: Get start up time¶
Start testpmd:
echo quit | time ./testpmd -c 0x3 -n 4 --huge-dir /mnt/huge -- -i
Get the time stats of the startup
Repeat step 1~2 for at least 5 times to get the average
44.4. Test Case 3: Clean up with Signal – testpmd¶
Create 4G hugepages, so that could save times when repeat:
echo 2048 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages mount -t hugetlbfs hugetlbfs /mnt/huge1
Start testpmd:
./testpmd -c 0x3 -n 4 --huge-dir /mnt/huge1 -- -i
Set fwd mac
Send packets from pkg
Check all packets could be fwd back
Kill the testpmd in shell using below commands alternately:
SIGINT: pkill -2 testpmd SIGTERM: pkill -15 testpmd
Repeat step 1-6 for 20 times, and packet must be fwd back with no error for each time.
44.5. Test Case 4: Clean up with Signal – l2fwd¶
Create 4G hugepages, so that could save times when repeat:
echo 2048 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages mount -t hugetlbfs hugetlbfs /mnt/huge1
Start testpmd:
./l2fwd -c 0x3 -n 4 --huge-dir /mnt/huge1 -- -p 0x01
Set fwd mac
Send packets from pkg
Check all packets could be fwd back
Kill the testpmd in shell using below commands alternately:
SIGINT: pkill -2 l2fwd SIGTERM: pkill -15 l2fwd
Repeat step 1-6 for 20 times, and packet must be fwd back with no error for each time.
44.6. Test Case 5: Clean up with Signal – l3fwd¶
Create 4G hugepages, so that could save times when repeat:
echo 2048 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages mount -t hugetlbfs hugetlbfs /mnt/huge1
Start testpmd:
./l3fwd -c 0x3 -n 4 --huge-dir /mnt/huge1 -- -p 0x01 --config="(0,0,1)"
Set fwd mac
Send packets from pkg
Check all packets could be fwd back
Kill the testpmd in shell using below commands alternately:
SIGINT: pkill -2 l3fwd SIGTERM: pkill -15 l3fwd
Repeat step 1-6 for 20 times, and packet must be fwd back with no error for each time.
