C Specification
The VkPhysicalDeviceMutableDescriptorTypeFeaturesVALVE structure is
defined as:
// Provided by VK_VALVE_mutable_descriptor_type
typedef struct VkPhysicalDeviceMutableDescriptorTypeFeaturesVALVE {
VkStructureType sType;
void* pNext;
VkBool32 mutableDescriptorType;
} VkPhysicalDeviceMutableDescriptorTypeFeaturesVALVE;
Description
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
mutableDescriptorTypeindicates that the implementation must support using the VkDescriptorType ofVK_DESCRIPTOR_TYPE_MUTABLE_VALVEwith at least the following descriptor types, where any combination of the types must be supported:-
VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE -
VK_DESCRIPTOR_TYPE_STORAGE_IMAGE -
VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER -
VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER -
VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER -
VK_DESCRIPTOR_TYPE_STORAGE_BUFFER
-
-
Additionally,
mutableDescriptorTypeindicates that:-
Non-uniform descriptor indexing must be supported if all descriptor types in a VkMutableDescriptorTypeListVALVE for
VK_DESCRIPTOR_TYPE_MUTABLE_VALVEhave the corresponding non-uniform indexing features enabled in VkPhysicalDeviceDescriptorIndexingFeatures. -
VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BITwithdescriptorTypeofVK_DESCRIPTOR_TYPE_MUTABLE_VALVErelaxes the list of required descriptor types to the descriptor types which have the corresponding update-after-bind feature enabled in VkPhysicalDeviceDescriptorIndexingFeatures. -
Dynamically uniform descriptor indexing must be supported if all descriptor types in a VkMutableDescriptorTypeListVALVE for
VK_DESCRIPTOR_TYPE_MUTABLE_VALVEhave the corresponding dynamic indexing features enabled. -
VK_DESCRIPTOR_SET_LAYOUT_CREATE_HOST_ONLY_POOL_BIT_VALVEmust be supported. -
VK_DESCRIPTOR_POOL_CREATE_HOST_ONLY_BIT_VALVEmust be supported.
-
If the VkPhysicalDeviceMutableDescriptorTypeFeaturesVALVE 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.
VkPhysicalDeviceMutableDescriptorTypeFeaturesVALVE can also be used in the pNext chain of
VkDeviceCreateInfo to selectively enable these features.
