You mean test programs using these sysfs files? Currently I just did some simple demos like the following:

cat config/STS_private_open
echo 1 > CMD_CLOSE_PRIVATE
cat config/STS_private_open

cat config/STS_ locality_1_open
echo 1 > CMD_CLOSE_LOCALITY1
cat config/ STS_ locality_1_open
echo 1 > CMD_OPEN_LOCALITY1
cat config/ STS_ locality_1_open

Thanks,
