Description

There are scenarios where the application does not know ahead of time how many descriptor sets it may need to allocate from a descriptor pool, or how many descriptors of any of the descriptor types it may need to allocate from the descriptor pool.

This extension gives applications the ability to request the implementation allow more sets or descriptors to be allocated than initially specified at descriptor pool creation time, subject to available resources.

The DESCRIPTOR_POOL_CREATE_ALLOW_OVERALLOCATION_SETS_BIT_NV flag lets the application allocate more than DescriptorPoolCreateInfo::maxSets descriptor sets, and the DESCRIPTOR_POOL_CREATE_ALLOW_OVERALLOCATION_POOLS_BIT_NV lets the application allocate more descriptors than initially specified by DescriptorPoolSize::descriptorCount for any descriptor types.

VkPhysicalDeviceDescriptorPoolOverallocationFeaturesNV - Structure describing feature to allow descriptor pool overallocation

Members

This structure describes the following feature:

Description

If the PhysicalDeviceDescriptorPoolOverallocationFeaturesNV 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. PhysicalDeviceDescriptorPoolOverallocationFeaturesNV can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.
