firmware_TouchMTB: add scripts to print SYN_REPORT intervals
It is handy to have scripts to print the time intervals between
SYN_REPORT packets in real time for a touchpad or touchscreen
device. In addition, the number of packets with large intervals
greater than 1/60 second is also displayed. A copy of the raw data
is saved with the filename specified by a command line option.
BUG=chromium:252152
TEST=Execute the script at any directory on a chromebook.
$ cd /usr/local/autotest/tests/firmware_TouchMTB
The default device node is touchpad.
$ tools/print_syn.sh
Or you can specify 'touchscreen' on a Pixel.
$ tools/print_syn.sh -d touchscreen
It would print something like:
...
interval: 0.008986 (Event: time 273574.295486, --- SYN_REPORT ---)
interval: 0.009091 (Event: time 273574.304577, --- SYN_REPORT ---)
interval: 0.008975 (Event: time 273574.313552, --- SYN_REPORT ---)
***** interval: 0.034414 (Event: time 273574.347966, --- SYN_REPORT ---)
...
the count of large intervals: 1 out of 23 packets
You could also specify the raw data file name with the "-f" option. E.g.,
$ tools/print_syn.sh -f /tmp/circle_interval.dat
And check the existence of the raw data file.
