Normal device memory -- allocations must support memory aliasing and sparse binding, which could -- interfere with optimizations like framebuffer compression or efficient -- page table usage. This is important for render targets and very large -- resources, but need not (and probably should not) be used for smaller -- resources that can benefit from suballocation. -- -- This extension adds a few small structures to resource creation and -- memory allocation: a new structure that flags whether am image\/buffer -- will have a dedicated allocation, and a structure indicating the image -- or buffer that an allocation will be bound to. -- -- == New Structures -- -- - Extending 'Vulkan.Core10.Buffer.BufferCreateInfo': -- -- - 'DedicatedAllocationBufferCreateInfoNV' -- -- - Extending 'Vulkan.Core10.Image.ImageCreateInfo': -- -- - 'DedicatedAllocationImageCreateInfoNV' -- -- - Extending 'Vulkan.Core10.Memory.MemoryAllocateInfo': -- -- - 'DedicatedAllocationMemoryAllocateInfoNV' -- -- == New Enum Constants -- -- - 'NV_DEDICATED_ALLOCATION_EXTENSION_NAME' -- -- - 'NV_DEDICATED_ALLOCATION_SPEC_VERSION' -- -- - Extending 'Vulkan.Core10.Enums.StructureType.StructureType': -- -- - 'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_DEDICATED_ALLOCATION_BUFFER_CREATE_INFO_NV' -- -- - 'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_DEDICATED_ALLOCATION_IMAGE_CREATE_INFO_NV' -- -- - 'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_DEDICATED_ALLOCATION_MEMORY_ALLOCATE_INFO_NV' -- -- == Examples -- -- > // Create an image with -- > // VkDedicatedAllocationImageCreateInfoNV::dedicatedAllocation -- > // set to VK_TRUE -- > -- > VkDedicatedAllocationImageCreateInfoNV dedicatedImageInfo = -- > { -- > VK_STRUCTURE_TYPE_DEDICATED_ALLOCATION_IMAGE_CREATE_INFO_NV, // sType -- > NULL, // pNext -- > VK_TRUE, // dedicatedAllocation -- > }; -- > -- > VkImageCreateInfo imageCreateInfo = -- > { -- > VK_STRUCTURE_TYPE_IMAGE_CREATE_INFO, // sType -- > &dedicatedImageInfo // pNext -- > // Other members set as usual -- > }; -- > -- > VkImage image; -- > VkResult result = vkCreateImage( -- > device, -- > &imageCreateInfo, -- > NULL, // pAllocator -- > &image); -- > -- > VkMemoryRequirements memoryRequirements; -- > vkGetImageMemoryRequirements( -- > device, -- > image, -- > &memoryRequirements); -- > -- > // Allocate memory with VkDedicatedAllocationMemoryAllocateInfoNV::image -- > // pointing to the image we are allocating the memory for -- > -- > VkDedicatedAllocationMemoryAllocateInfoNV dedicatedInfo = -- > { -- > VK_STRUCTURE_TYPE_DEDICATED_ALLOCATION_MEMORY_ALLOCATE_INFO_NV, // sType -- > NULL, // pNext -- > image, // image -- > VK_NULL_HANDLE, // buffer -- > }; -- > -- > VkMemoryAllocateInfo memoryAllocateInfo = -- > { -- > VK_STRUCTURE_TYPE_MEMORY_ALLOCATE_INFO, // sType -- > &dedicatedInfo, // pNext -- > memoryRequirements.size, // allocationSize -- > FindMemoryTypeIndex(memoryRequirements.memoryTypeBits), // memoryTypeIndex -- > }; -- > -- > VkDeviceMemory memory; -- > vkAllocateMemory( -- > device, -- > &memoryAllocateInfo, -- > NULL, // pAllocator -- > &memory); -- > -- > // Bind the image to the memory -- > -- > vkBindImageMemory( -- > device, -- > image, -- > memory, -- > 0); -- -- == Version History -- -- - Revision 1, 2016-05-31 (Jeff Bolz) -- -- - Internal revisions -- -- == See Also -- -- 'DedicatedAllocationBufferCreateInfoNV', -- 'DedicatedAllocationImageCreateInfoNV', -- 'DedicatedAllocationMemoryAllocateInfoNV' -- -- == Document Notes -- -- For more information, see the -- -- -- This page is a generated document.
