	)

Creates PI context object from a native handle.

NOTE: The created PI object takes ownership of the native handle. NOTE: The number of devices and the list of devices is needed for Level Zero backend because there is no possilibity to query this information from context handle for Level Zero. If backend has API to query a list of devices from the context native handle then these parameters are ignored.

Parameters

nativeHandle	is the native handle to create PI context from.
numDevices	is the number of devices in the context. Parameter is ignored if number of devices can be queried from the context native handle for a backend.
devices	is the list of devices in the context. Parameter is ignored if devices can be queried from the context native handle for a backend.
pluginOwnsNativeHandle	Indicates whether the created PI object should take ownership of the native handle.
context	is the PI context created from the native handle.

Returns: PI_SUCCESS if successfully created pi_context from the handle. PI_OUT_OF_HOST_MEMORY if can't allocate memory for the pi_context object. PI_INVALID_VALUE if numDevices == 0 or devices is NULL but backend doesn't have API to query a list of devices from the context native handle. PI_UNKNOWN_ERROR in case of another error.

API to query information from the sub-group from a kernel.

Parameters

kernel	is the pi_kernel to query

input_value	is the ptr to the input value passed.
param_value_size	is the size of the value in bytes.
param_value	is a pointer to the value to set.
param_value_size_ret	is a pointer to return the size of data in param_value ptr.

All queries expect a return of 4 bytes in param_value_size, param_value_size_ret, and a uint32_t value should to be written in param_value ptr. Note: This behaviour differs from OpenCL. OpenCL returns size_t.

Parameters

message is a returned address to the first element in the message the plugin owns the error message string. The string is thread-local. As a result, different threads may return different errors. A message is overwritten by the following error or warning that is produced within the given thread. The memory is cleaned up at the end of the thread's lifetime.

Returns: PI_SUCCESS if plugin is indicating non-fatal warning. Any other error code indicates that plugin considers this to be a fatal error and the runtime must handle it or end the application.
