[PATCH 13/16] drm/i915/vm_bind: Update i915_vma_verify_bind_complete()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Ensure i915_vma_verify_bind_complete() handles case where bind
is not initiated. Also make it non static, add documentation
and move it out of CONFIG_DRM_I915_DEBUG_GEM.
