Imports

Native bindings to the khr_command_buffer extension.

Command-buffers enable a reduction in overhead when enqueuing the same workload multiple times. By separating the command-queue setup from dispatch, the ability to replay a set of previously created commands is introduced.

Device-side cl_sync_point_khr synchronization-points can be used within command-buffers to define command dependencies. This allows the commands of a command-buffer to execute out-of-order on a single compatible command-queue. The command-buffer itself has no inherent in-order/out-of-order property, this ordering is inferred from the command-queue used on command recording. Out-of-order enqueues without event dependencies of both regular commands, such as EnqueueFillBuffer, and command-buffers are allowed to execute concurrently, and it is up to the user to express any dependencies using events.

The command-queues a command-buffer will be executed on can be set on replay via parameters to EnqueueCommandBufferKHR, provided they are compatible with the command-queues used on command-buffer recording.

Requires CL12.

Parameter is unused by this extension as only a single command-queue is supported and must be NULL.

command_queue, IntBuffer

If sync_point_wait_list is NULL, num_sync_points_in_wait_list must be 0. If sync_point_wait_list is not NULL, the list of synchronization-points pointed to by sync_point_wait_list must be valid and num_sync_points_in_wait_list must be greater than 0. The synchronization-points specified in sync_point_wait_list are device side synchronization-points. The command-buffer associated with synchronization-points in sync_point_wait_list must be the same as command_buffer.

Synchronization-point objects are unique and can be used to identify this barrier command later on. sync_point can be NULL in which case it will not be possible for the application to record a wait for this command to complete.
