GPU: Disable Hangcheck
This section applies only to applications with long-running GPU compute workloads in native environments. It is not recommended for virtualizations or other standard usages of GPU, such as gaming.
A workload that takes more than four seconds for GPU hardware to execute is a long-running workload. By default, individual threads that qualify as long-running workloads are considered hung and are terminated. By disabling the hangcheck timeout period, you can avoid this problem.
NOTE:
If the system is rebooted, hangcheck is automatically enabled. You must disable hangcheck again after every reboot or follow the directions below to disable hangcheck persistently (across multiple reboots). Please re-run this GPU Hangcheck disable with reboot fix if you update (or auto-update) the kernel.
To disable hangcheck until the next reboot:
sudo sh -c "echo N> /sys/module/i915/parameters/enable_hangcheck"
To disable hangcheck across multiple reboots:
NOTE:
If the kernel is updated, hangcheck is automatically enabled. Run the procedure below after every kernel update to ensure hangcheck is disabled.
Open a terminal.
Open the grub file in /etc/default.
In the grub file, find the line GRUB_CMDLINE_LINUX_DEFAULT="".
Enter the following text between the quotes (“”):
i915.enable_hangcheck=0
Run the following command:
sudo update-grub
Reboot the system. Hangcheck remains disabled.
