Hi there,
I am trying to setup and run VPP HPS in my local vagrant vm. There I have 2 x
1Gbs (82540EM EC) configured for VPP. I configured HPS placement per:
/etc/vpp/startup.conf
cpu {
...
main-core 0
corelist-workers 1, 2
corelist-hqos-threads 3
...
}
dpdk {
...
socket-mem 1024
dev 0000:00:08.0 {
num-rx-queues 1
}
dev 0000:00:09.0 {
num-tx-queues 1
hqos
}
}
vpp# show dpdk version
DPDK Version: DPDK 16.11.0
DPDK EAL init args: -c f -n 4 --huge-dir /run/vpp/hugepages --file-prefix
vpp -w 0000:00:08.0 -w 0000:00:09.0 --master-lcore 0 --socket-mem 1024
I assigned the following static arp-s and a route for my simple test:
vpp# sh int
Name Idx State Counter Count
GigabitEthernet0/8/0 1 down
GigabitEthernet0/9/0 2 down
local0 0 down
vpp# set int ip address GigabitEthernet0/8/0 10.10.0.1/24
vpp# set interface state GigabitEthernet0/8/0 up
vpp# set int ip address GigabitEthernet0/9/0 10.10.0.10/24
vpp# set interface state GigabitEthernet0/9/0 up
vpp# set ip arp static GigabitEthernet0/9/0 10.10.10.1 08:00:27:25:8A:0F
vpp# set ip arp static GigabitEthernet0/9/0 10.10.10.2 08:00:27:25:8A:0F
vpp# set ip arp static GigabitEthernet0/9/0 10.10.10.3 08:00:27:25:8A:0F
vpp# set ip arp static GigabitEthernet0/9/0 10.10.10.4 08:00:27:25:8A:0F
vpp# ip route add 10.10.10.255/24 via GigabitEthernet0/9/0
vpp# show dpdk interface placement
Thread 2 (vpp_wk_0 at lcore 1):
GigabitEthernet0/8/0 queue 0
Thread 3 (vpp_wk_1 at lcore 2):
GigabitEthernet0/9/0 queue 0
I sent the traffic from my traffic generator (Dst IPv4 range 10.10.10.1-4, and
random DSCP). From the trace log I cannot see the packet hitting the HPS:
vpp# clear trace
vpp# trace add dpdk-input 10
vpp# show trace

The VPP documentation shows the following HPS cli commands:
set dpdk interface hqos pipe <if-name> subport <n> pipe <n> profile <n>
set dpdk interface hqos pktfield <if-name> id <n> offset <n> mask <n>
set dpdk interface hqos placement <if-name> thread <n>
set dpdk interface hqos subport <if-name> subport <n> [rate <n>] [bktsize
<n>] [tc0 <n>] [tc1 <n>] [tc2 <n>] [tc3 <n>] [period <n>]
set dpdk interface hqos tctbl <if-name> entry <n> tc <n> queue <n>
set dpdk interface placement <if-name> [queue <n>] thread <n>
show dpdk hqos queue <if-name> subport <subport> pipe <pipe> tc <tc> tc_q
<tc_q>
show dpdk interface hqos placement
show dpdk interface hqos <if-name>
show dpdk interface placement
This is the HPS placement shown in my setup:
vpp# show dpdk interface hqos placement
Thread 1 (vpp_hqos-threads_0 at lcore 3):
GigabitEthernet0/9/0 queue 0
vpp# show dpdk interface placement
Thread 2 (vpp_wk_0 at lcore 1):
GigabitEthernet0/8/0 queue 0
Thread 3 (vpp_wk_1 at lcore 2):
GigabitEthernet0/9/0 queue 0
vpp# show dpdk interface hqos placement
Thread 1 (vpp_hqos-threads_0 at lcore 3):

How someone can configure VPS HPS port parameters form the VPP CLI? I only see
the default port attributes set as per
https://docs.fd.io/vpp/17.01/d5/dd9/hqos_8c_source.html
..
95 /* port */
96 .port = {
97 .name = NULL, /* Set at init */
98 .socket = 0, /* Set at init */
99 .rate = 1250000000, /* Assuming 10GbE port */
100 .mtu = 14 + 1500, /* Assuming Ethernet/IPv4 pkt (Ethernet
FCS not included) */
101 .frame_overhead = RTE_SCHED_FRAME_OVERHEAD_DEFAULT,
102 .n_subports_per_port = 1,
103 .n_pipes_per_subport = 4096,
104 .qsize = {64, 64, 64, 64},
105 .pipe_profiles = NULL, /* Set at config */
106 .n_pipe_profiles = 1,
I cannot change the default setting:
vpp# set dpdk interface hqos pipe GigabitEthernet0/9/0 subport 0 pipe 0 profile 0
vpp# set dpdk interface hqos subport GigabitEthernet0/9/0 subport 0 rate
125000000 bktsize 10000 tc0 30517 tc1 30517 tc2 30517 tc3 30517 period 80

I appreciate any help with my HPS setup.
Thank you,
