VkPhysicalDeviceNestedCommandBufferFeaturesEXT

The VkPhysicalDeviceNestedCommandBufferFeaturesEXT structure is defined as:

typedef struct VkPhysicalDeviceNestedCommandBufferFeaturesEXT {
    VkStructureType sType;
    void* pNext;
    VkBool32 nestedCommandBuffer;
    VkBool32 nestedCommandBufferRendering;
    VkBool32 nestedCommandBufferSimultaneousUse;
} VkPhysicalDeviceNestedCommandBufferFeaturesEXT;

This structure describes the following features:

• nestedCommandBuffer indicates the implementation supports nested command buffers, which allows Secondary Command Buffers to execute other Secondary Command Buffers.
• nestedCommandBufferRendering indicates that it is valid to call vkCmdExecuteCommands inside a Secondary Command Buffer recorded with VK_COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT.
• nestedCommandBufferSimultaneousUse indicates that the implementation supports nested command buffers with command buffers that are recorded with VK_COMMAND_BUFFER_USAGE_SIMULTANEOUS_USE_BIT.

If the VkPhysicalDeviceNestedCommandBufferFeaturesEXT 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 VkPhysicalDeviceNestedCommandBufferFeaturesEXT, 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.
