How to disable TDR in Jetson Nano

[AastaLLL]

Hi,

We do limit the GPU kernel to 5 seconds on Jetson Nano.
For any GPU task that runs over 5s, it will be killed by the watchdog automatically.

It’s not recommended to disable this mechanism since Nano doesn’t have slice support to share GPU resources.
But if this is good for your use case, please check the following comment for the detailed steps:

Kernel launch timeout

Hi, A workaround is to disable the GPU timeout watchdog: $ sudo -s $ echo N > /sys/kernel/debug/gpu.0/timeouts_enabled But please note that Nano doesn’t have slice support. Other kernels will need to wait for the previous one to finish to get the resources. (In the full GPU load cases) After doing this, we can get the correct PI output with your app. Please also note that you can maximize the Nano performance with the following command: $ sudo nvpmodel -m 0 $ sudo jetson_clocks Thanks.

Thanks.
