8.1.3.2.4 Using taprio Qdisc Setup Qbv
LS1028ardb support the tarprio qdisc to setup Qbv either. Below is an example Setup.
#Qbv test do not require the mqprio setting.
# If mqprio is enabled, try to disable it by below command:
tc qdisc del dev eno0 root handle 1: mqprio
# Enable the Qbv for ENETC eno0 port
# Below command set eno0 with gate 0x01, means queue 0 open, the other queues gate close.
tc qdisc replace dev eno0 parent root handle 100 taprio num_tc 8 map 0 1 2 3 4 5 6 7 queues 1@0 1@1 1@2
1@3 1@4 1@5 1@6 1@7 base-time 0 sched-entry S 01 300000 flags 0x2
# Ping through eno0 port should be ok
# Then close the gate queue 0. Open gate queue 1. The other queues gate close.
tc qdisc replace dev eno0 parent root handle 100 taprio num_tc 8 map 0 1 2 3 4 5 6 7 queues 1@0 1@1 1@2
1@3 1@4 1@5 1@6 1@7 base-time 0 sched-entry S 02 300000 flags 0x2
# Ping through eno0 port should be dropped
#Disable the Qbv for ENETC eno0 port as below
tc qdisc del dev eno0 parent root handle 100 taprio
8.1.3.3 Qci test cases
Use the following as the background setting:
• Set eno0 MAC address
ip link set eno0 address 10:00:80:00:00:00
Opposite port MAC address 99:aa:bb:cc:dd:ee as frame provider as example.
• Use the figure below as the hardware setup.
