I use setDLACore() to select which DLA to work, and get DLA information via the command shared below.
watch -n 1 "cat /sys/devices/platform/host1x/15880000.nvdla0/power/runtime_status"
watch -n 1 "cat /sys/devices/platform/host1x/158c0000.nvdla1/power/runtime_status"
But whenever I select DLA0 or DLA1, always the DLA0 is active and DLA1 is suspended
