Max-Q and Max-P Power Efficiency

It supports three different power modes such as 10W, 15W, and 30W. For each mode, several configurations with various CPU and GPU frequencies, and a number of cores online are possible.

Mode ID	0	1	2	3	4	5	6
Power Budget	EDP	10W	15W	30W	30W	30W	30W
Online CPU	8	2	4	8	6	4	2
CPU Max Frequency (MHz)	2265.6	1200	1200	1200	1450	1780	2100
GPU Max Frecuency (MHz)	1377	520	670	900	900	900	900
DLA Max Frequency (MHz)	1395.2	550	750	1050	1050	1050	1050
PVA Cores	2	0	1	1	1	1	1
PVA Max Frequency (MHz)	1088	0	550	760	760	760	760
Max Frequency	2133	1066	1333	1600	1600	1600	1600

The default mode is id 2. EDP represents the limits and therefore has no power budget

A utility is provided to change the board operations between these modes. In order to change the current operation mode using the command:

ID=5
sudo /usr/sbin/nvpmodel -m $ID

The mode persists across power cycles and won't change unless nvpmodel is called again.

In order to find the current mode use:

sudo /usr/sbin/nvpmodel -q

Extra Definitions can be added in a file located in:

/etc/nvpmodel/nvpmodel_t194.conf
