Scripts & Tools

jetson_clocks: script that disables the DVFS governor and locks the clocks to their maximums as defined by the active nvpmodel power mode. If the active nvpmodel mode is 10W, jetson_clocks will lock the clocks to their maximums for 10W mode. If the active nvpmodel is 5W, jetson_clocks will lock the clocks to their maximums for 5W mode.

/etc/nvpmodel.conf defines the nvpmodels.
