In ubuntu (Linux version 4.4.38 - tegra (buildbrain @ mobile - u64 - 773)) provided by jetpack 3.2.1, setting of SCHED_FIFO by pthread_setschedparam () now causes an error (errorno==1). In previous ubuntu provided by jetpack (Linux version 4.4.38 - tegra (buildbrain @ mobile - u64 - 753)), we did not make an error.
Has it been possible to limit the use of SCHED_FIFO?

Source files, makefiles, binaries and logs on success, binaries and logs on failure were prepared in github.
