+title: NVIDIA nvpmodel driver for emc clock cap

+
+description: |
+  Nvpmodel is a driver that provides sysfs nodes that allow capping certain clock
+  frequencies in order to keep the power consumption under a certain budget.
+
+  These caps are designed to be relatively static. They should not be used
+  during runtime (under load) to dynamically change the power budget
