VkPhysicalDeviceInternallySynchronizedQueuesFeaturesKHR(3)

# VkPhysicalDeviceInternallySynchronizedQueuesFeaturesKHR(3) Manual Page

## Name

VkPhysicalDeviceInternallySynchronizedQueuesFeaturesKHR - Structure indicating support for queues that are internally synchronized

## C Specification

The `VkPhysicalDeviceInternallySynchronizedQueuesFeaturesKHR` structure is defined as:

    // Provided by VK_KHR_internally_synchronized_queues
    typedef struct VkPhysicalDeviceInternallySynchronizedQueuesFeaturesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           internallySynchronizedQueues;
    } VkPhysicalDeviceInternallySynchronizedQueuesFeaturesKHR;

## Members

This structure describes the following feature:

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `internallySynchronizedQueues` indicates that VK_DEVICE_QUEUE_CREATE_INTERNALLY_SYNCHRONIZED_BIT_KHR can be used to make queues internally synchronized.

## Description

If the `VkPhysicalDeviceInternallySynchronizedQueuesFeaturesKHR` structure is included in the `pNext` chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by `VkPhysicalDeviceInternallySynchronizedQueuesFeaturesKHR`, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the `pNext` chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceInternallySynchronizedQueuesFeaturesKHR-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_INTERNALLY_SYNCHRONIZED_QUEUES_FEATURES_KHR

Structure Chaining

Extends the structures

  - VkDeviceCreateInfo

  - VkPhysicalDeviceFeatures2
