Test kernel scheduler behaviors with libhwbinder
It tests
1. supports priority inheritance.
2. utilize the sync flag.
It also makes statistic on average, best and worst latency
as well as number of deadline miss with a configurable
deadline specified in us. The output is in json format
usage:./libhwbinder_latency \
-i 1 # number of iterations
-pair 4 # number of process pairs
-deadline_us 2500 # deadline in us
-v # debug
-trace # halt the trace on a dealine hit
This -trace option stops trace once it detects a transaction
duration over the deadline. By writing '0' to
/sys/kernel/debug/tracing and halt the process. The tracelog is
then available on /sys/kernel/debug/trace
