sabarishsubramanian commented 4 years ago

Hello

I am trying to have a time sychronization of three TSN boards. I am trying to do in openil- community part.

The pdf which i have is of openil where they use SJA1105 tools and all. where in community part there is no more SJA1105 tools exits.

Could someone please help me how to start and proceed further?

Regards sabarish s

Even after i wait for the packets its the same.

Have you tried to e.g. increase the timeslot for ping traffic? yes i did i increased th window size to 100, 200 but still the output was the same.

sabarishsubramanian commented 4 years ago

When i try to ping from board 3 to board 1 the request reply pattern is been followed perfectly. But again the time is variable and is not getting locked at around 30 ms even after running it for more than 5 minutes.

sabarishsubramanian commented 4 years ago

for qbv demo

when i try to run the following script on board 2

!/bin/bash

set -e -u -o pipefail

NSEC_PER_SEC="1000000000"

gatemask() { local tc_list="$1" local mask=0

for tc in ${tc_list}; do
    mask=$((${mask} | (1 << ${tc})))
done

printf "%02x" ${mask}

}

Given @frame_len bytes, @count frames and @link_speed in Mbps,

returns the minimum number of nanoseconds required to keep a Qbv gate open

to transmit that.

qbv_window() { local frame_len=$1 local count=$2 local link_speed=$3 local bit_time=$((1000 / ${link_speed}))

7 bytes preamble, 1 byte SFD, 4 bytes FCS and 12 bytes IFG

local overhead=24
local octets=$((${frame_len} + ${overhead}))
local window=$((${octets} * 8 * ${bit_time}))

if [ $window -lt 1000 ]; then
    echo 1000
else
    echo $window
fi

}

if ! systemctl is-active --quiet linuxptp; then echo "Please start the linuxptp service" exit fi

speed_mbps=$(ethtool swp2 | gawk \ '/Speed:/ { speed=gensub(/^(.*)Mb\/s/, "\1", "g", $2); print speed; }')

now=$(phc_ctl /dev/ptp1 get | gawk '/clock time is/ { print $5; }')

Phase-align the base time to the start of the next second.

sec=$(echo "${now}" | gawk -F. '{ print $1; }') base_time="$(((${sec} + 1) * ${NSEC_PER_SEC}))"

30 ms

cycle_time=30000000

PTP: create a window for 1 packet of 200 bytes at the current link speed

t1=$(qbv_window 200 1 $speed_mbps)

ping: create a window for 1 packet of 64 bytes

t2=$(qbv_window 64 1 $speed_mbps)

Best effort: the rest of the time up to 30 ms

t0=$(($cycle_time - $t1 - $t2))

tc qdisc add dev swp2 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 ${base_time} \ sched-entry S $(gatemask 7) $t1 \ sched-entry S $(gatemask 5) $t2 \ sched-entry S $(gatemask "0 1 2 3 4 6") $t0 \ flags 2 My boards are going out of sync

In the actual script it was mentioned

sched-entry S $(gatemask 7) $t0 \ sched-entry S $(gatemask 5) $t1 \ sched-entry S $(gatemask "0 1 2 3 4 6") $t2 \ flags 2

But according to the theory which is mentioned

The mapping on Board 2's switch between VLAN PCP and traffic classes is implicitly one to 1, so VLAN PCP 5 goes to traffic class 5, etc.

PTP traffic goes to traffic class 7 by default.

so i changed the script n did but the boards went out of sync.

If you still have problems I recommend using the master branch, where this bug has been found and fixed: https://github.com/openil/linux/commit/adc93ad9ad0e51c8c10700c2d846ffeb3a1a2ced
