Detailed Description

Allocates and hands out std::shared_ptr<QueueHandle> instances for thread-safe access to Vulkan Queues.

Each QueueHandle represents a single Vulkan Queue. Many shared pointers to a single QueueHandle may exist at a given time, e.g. if the GPU only provides a single queue of the required type.

Member Function Documentation

GetQueueWithFlags()

shared_ptr< QueueHandle > QueueManager::GetQueueWithFlags	(	vk::QueueFlags	flags,
		std::string	name
	)

Get a handle to a queue that has the given flag bits set, allocating the queue if necessary, and set or append name to the queue name for debug

GetRenderQueue()

std::shared_ptr< QueueHandle > QueueManager::GetRenderQueue ( std::string  name )

inline

Get a handle to a render queue

Note

Currently this requires Graphics and Transfer capabilities to simplify texture transfer code in WaveformArea.

GetTransferQueue()

std::shared_ptr< QueueHandle > QueueManager::GetTransferQueue ( std::string  name )

inline

Get a handle to a transfer queue

Note

This currently requires Compute capabilities so we can barrier on compute operations
