vdec: add trace for decode time [1/1]
PD#GH-117
BUG=144472057
Problem:
Google need trace for decoder spend time
Solution:
Add trace to print decoder spend time, need below commands:
echo 1 > /sys/kernel/debug/tracing/events/meson_atrace/enable
echo 2 > /sys/class/debug/atrace_tag #only need 1 time
echo 1 > /sys/module/decoder_common/parameters/dec_time_stat_flag
Verify:
