CONFIG_DRM_I915_SPIN_REQUEST: Busywait for request completion (us)

General informations

The Linux kernel configuration item CONFIG_DRM_I915_SPIN_REQUEST:

Help text

Before sleeping waiting for a request (GPU operation) to complete, we may spend some time polling for its completion. As the IRQ may take a non-negligible time to setup, we do a short spin first to check if the request will complete in the time it would have taken us to enable the interrupt.

May be 0 to disable the initial spin. In practice, we estimate the cost of enabling the interrupt (if currently disabled) to be a few microseconds.
