General informations

The Linux kernel configuration item CONFIG_DRM_I915_PREEMPT_TIMEOUT:

Help text

How long to wait (in milliseconds) for a preemption event to occur when submitting a new context via execlists. If the current context does not hit an arbitration point and yield to HW before the timer expires, the HW will be reset to allow the more important context to execute.

This is adjustable via /sys/class/drm/card?/engine/*/preempt_timeout_ms

May be 0 to disable the timeout.

The compiled in default may get overridden at driver probe time on certain platforms and certain engines which will be reflected in the sysfs control.
