Member Data Documentation

InitialSize

Uint64 Diligent::DeviceMemoryCreateInfo::InitialSize = 0

Initial size of the memory object.

Some implementations do not support IDeviceMemory::Resize() and memory can only be allocated during the initialization.

ppCompatibleResources

IDeviceObject** Diligent::DeviceMemoryCreateInfo::ppCompatibleResources = nullptr

An array of NumResources resources that this memory must be compatible with.

For sparse memory, only Diligent::USAGE_SPARSE buffer and texture resources are allowed.

Vulkan backend requires at least one resource to be provided.

In Direct3D12, the list of resources is optional on D3D12_RESOURCE_HEAP_TIER_2-hardware and above, but is required on D3D12_RESOURCE_HEAP_TIER_1-hardware (see SPARSE_RESOURCE_CAP_FLAG_MIXED_RESOURCE_TYPE_SUPPORT).

It is recommended to always provide the list.
