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.

data PhysicalDeviceDescriptorPoolOverallocationFeaturesNV Source #
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. If the application wishes to use a
Device with any features described by
PhysicalDeviceDescriptorPoolOverallocationFeaturesNV, 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.
