Description

This extension adds a new loop control hint to the SPIR-V execution environment, instructing the compiler that it should use multiple wait queues to optimize a loop.

This can improve performance for loops that have high latency instructions such as for VK_KHR_cooperative_matrix operations, by allowing the compiler to issue instructions for future iterations while waiting for the current iteration to complete.

VkPhysicalDeviceShaderMultipleWaitQueuesFeaturesQCOM - Structure describing whether shader multiple wait queues can be supported by an implementation

Members

This structure describes the following feature:

Description

If the PhysicalDeviceShaderMultipleWaitQueuesFeaturesQCOM structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a Device with any features described by PhysicalDeviceShaderMultipleWaitQueuesFeaturesQCOM, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.

VkPhysicalDeviceShaderMultipleWaitQueuesPropertiesQCOM - Structure describing shader multiple wait queues properties that can be supported by an implementation

Description

If the PhysicalDeviceShaderMultipleWaitQueuesPropertiesQCOM structure is included in the pNext chain of the PhysicalDeviceProperties2 structure passed to getPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.
