VI controller notify log .. VI_NOTIFY

Hi All

We use nvidia jetson TX2 board and want to enable VI_NOTIFY log to check what happen and we were trying to give the following command. But, we couldn’t find ‘tracing’ folder in ‘debug’ folder

echo 1 > /sys/kernel/debug/tracing/tracing_on
echo 30720 > /sys/kernel/debug/tracing/buffer_size_kb
echo 1 > /sys/kernel/debug/tracing/events/tegra_rtcpu/enable
echo 1 > /sys/kernel/debug/tracing/events/freertos/enable
echo 2 > /sys/kernel/debug/camrtc/log-level
echo > /sys/kernel/debug/tracing/trace

cat /sys/kernel/debug/tracing/trace

thanks in advance…
