DRM_IOCTL_QAIC_DETACH_SLICE_BO

  This IOCTL allows userspace to remove the slicing information from a BO that

  was originally provided by a call to DRM_IOCTL_QAIC_ATTACH_SLICE_BO. This

  is the inverse of DRM_IOCTL_QAIC_ATTACH_SLICE_BO. The BO must be idle for

  DRM_IOCTL_QAIC_DETACH_SLICE_BO to be called. After a successful detach slice

  operation the BO may have new slicing information attached with a new call

  to DRM_IOCTL_QAIC_ATTACH_SLICE_BO. After detach slice, the BO cannot be

  executed until after a new attach slice operation. Combining attach slice

  and detach slice calls allows userspace to use a BO with multiple workloads.
