1.Can we run 3 cores in low power mode 5W? by making changes in nvpmodel.conf.
2.If its possible can i try to define my custom power mode in jetson NANO, i had go through below link.
In the above link they defined we can add and test our custom mode,if its possible. i want to run with 3 or 4 cores in 5W mode, what are the parameters i want to change.
how to calculate the GPU,EMC,CPU frequency to update in the nvpmodel.conf file.
Below is the example from the document
To define a custom power mode
• Add a mode definition to the file /etc/nvpmodel.conf.
This is an example entry for mode 1:
< POWER_MODEL ID=1 NAME=5W >
CPU_ONLINE CORE_0 1
CPU_ONLINE CORE_1 1
CPU_ONLINE CORE_2 0
CPU_ONLINE CORE_3 0
CPU_A57 MIN_FREQ 0
CPU_A57 MAX_FREQ 918000
GPU_POWER_CONTROL_ENABLE GPU_PWR_CNTL_EN on
GPU MIN_FREQ 0
GPU MAX_FREQ 640000000
GPU_POWER_CONTROL_DISABLE GPU_PWR_CNTL_DIS auto
EMC MAX_FREQ 1600000000
The unit of measure for CPU frequency is kilohertz. The unit for GPU and EMMC frequency is hertz. You must assign each custom mode a unique number in the ID field.
Test your custom mode to determine:
• How many active cores to use
• The frequency for each CPU cluster, and the GPU and EMC frequencies
The frequencies you select are subject to the MAXN limit defined in mode 0.
Can anyone help me to figure out the details for custom power mode.
