/**
* struct i915_context_engines_parallel_submit - Configure engine for
* parallel submission.
*
* Setup a slot in the context engine map to allow multiple BBs to be submitted
* in a single execbuf IOCTL. Those BBs will then be scheduled to run on the GPU
* in parallel. Multiple hardware contexts are created internally in the i915 to
* run these BBs. Once a slot is configured for N BBs only N BBs can be
* submitted in each execbuf IOCTL and this is implicit behavior e.g. The user
* doesn't tell the execbuf IOCTL there are N BBs, the execbuf IOCTL knows how
* many BBs there are based on the slot's configuration. The N BBs are the last
* N buffer objects or first N if I915_EXEC_BATCH_FIRST is set.
*
* The default placement behavior is to create implicit bonds between each
* context if each context maps to more than 1 physical engine (e.g. context is
* a virtual engine). Also we only allow contexts of same engine class and these
* contexts must be in logically contiguous order. Examples of the placement
* behavior are described below. Lastly, the default is to not allow BBs to be
* preempted mid-batch. Rather insert coordinated preemption points on all
* hardware contexts between each set of BBs. Flags could be added in the future
* to change both of these default behaviors.
*
* Returns -EINVAL if hardware context placement configuration is invalid or if
* the placement configuration isn't supported on the platform / submission
* interface.
* Returns -ENODEV if extension isn't supported on the platform / submission
* interface.
*
* .. code-block:: none
*
* Examples syntax:
* CS[X] = generic engine of same class, logical instance X
* INVALID = I915_ENGINE_CLASS_INVALID, I915_ENGINE_CLASS_INVALID_NONE
*
* Example 1 pseudo code:
* set_engines(INVALID)
* set_parallel(engine_index=0, width=2, num_siblings=1,
* engines=CS[0],CS[1])
*
* Results in the following valid placement:
* CS[0], CS[1]
*
* Example 2 pseudo code:
* set_engines(INVALID)
* set_parallel(engine_index=0, width=2, num_siblings=2,
* engines=CS[0],CS[2],CS[1],CS[3])
*
* Results in the following valid placements:
* CS[0], CS[1]
* CS[2], CS[3]
*
* This can be thought of as two virtual engines, each containing two
* engines thereby making a 2D array. However, there are bonds tying the
* entries together and placing restrictions on how they can be scheduled.
* Specifically, the scheduler can choose only vertical columns from the 2D
* array. That is, CS[0] is bonded to CS[1] and CS[2] to CS[3]. So if the
* scheduler wants to submit to CS[0], it must also choose CS[1] and vice
* versa. Same for CS[2] requires also using CS[3].
* VE[0] = CS[0], CS[2]
* VE[1] = CS[1], CS[3]
*
* Example 3 pseudo code:
* set_engines(INVALID)
* set_parallel(engine_index=0, width=2, num_siblings=2,
* engines=CS[0],CS[1],CS[1],CS[3])
*
* Results in the following valid and invalid placements:
* CS[0], CS[1]
* CS[1], CS[3] - Not logically contiguous, return -EINVAL
