Yep:
root@valsch-h960:~# zcat /proc/config.gz | grep SMT
CONFIG_SCHED_SMT=y
root@valsch-h960:~# ./set_governor.sh schedutil
[ 127.834363] root_domain 0-7: pd4:{ cpus=4-7 nr_cstate=5 } pd0:{ cpus=0-3 nr_cstate=5 }
[ 127.842344] sched_energy_set: starting EAS
No reason for it not to come up unless something's broken (but it's
always good to check!).
