在类似Linux的系统上更改GPU时钟速率(Nvidia Jetson TX1) [英] Changing the GPU clock rate on a linux like system (Nvidia Jetson TX1)

问题描述

我有一个Nvidia Jetson tx1开发板，想通过写入以下文件来更改gpu速率:

I have a Nvidia Jetson tx1 board and want to change the gpu rate by writing in the following file:

sudo echo 691200000 > /sys/kernel/debug/clock/override.gbus/rate
sudo echo 1 > /sys/kernel/debug/clock/override.gbus/state

但是我受到了

权限被拒绝

Permission denied

我知道以下脚本中的命令 https://nvidia-employee提出的/github.com/dusty-nv/jetson-scripts/blob/master/jetson_max_l4t.sh .但是我不想最大化gpu时钟频率，我想将其设置为特定设置.

I know the commands from the following script https://github.com/dusty-nv/jetson-scripts/blob/master/jetson_max_l4t.sh which was proposed by an nvidia-employee. However I do not want to max out the gpu clock frequency, I want to set it to a specific setting.

推荐答案

这里的问题是重定向发生在非root用户环境中，而不是在sudo下.

The problem here is the redirection happens in your non-root user environment, not under sudo.

尝试以下方法:

sudo bash -c 'echo 691200000 > /sys/kernel/debug/clock/override.gbus/rate'

，第二种设置也是如此.

and similarly for the second setting.
