Arguments

:: forall io. MonadIO io

=> Device

device is the logical device that owns the buffer and memory.

-> Buffer

buffer is the buffer to be attached to memory.

-> DeviceMemory

memory is a DeviceMemory object describing the device memory to attach.

vkBindBufferMemory - Bind device memory to a buffer object

Description

bindBufferMemory is equivalent to passing the same parameters through BindBufferMemoryInfo to bindBufferMemory2.

Valid Usage

• buffer must not already be backed by a memory object

• buffer must not have been created with any sparse memory binding flags
• memoryOffset must be less than the size of memory
• memory must have been allocated using one of the memory types allowed in the memoryTypeBits member of the MemoryRequirements structure returned from a call to getBufferMemoryRequirements with buffer
• memoryOffset must be an integer multiple of the alignment member of the MemoryRequirements structure returned from a call to getBufferMemoryRequirements with buffer
• The size member of the MemoryRequirements structure returned from a call to getBufferMemoryRequirements with buffer must be less than or equal to the size of memory minus memoryOffset
• If buffer requires a dedicated allocation(as reported by getBufferMemoryRequirements2 in MemoryDedicatedRequirements::requiresDedicatedAllocation for buffer), memory must have been created with MemoryDedicatedAllocateInfo::buffer equal to buffer
• If the MemoryAllocateInfo provided when memory was allocated included a MemoryDedicatedAllocateInfo structure in its pNext chain, and MemoryDedicatedAllocateInfo::buffer was not NULL_HANDLE, then buffer must equal MemoryDedicatedAllocateInfo::buffer, and memoryOffset must be zero
• If buffer was created with the BUFFER_CREATE_PROTECTED_BIT bit set, the buffer must be bound to a memory object allocated with a memory type that reports MEMORY_PROPERTY_PROTECTED_BIT
• If buffer was created with the BUFFER_CREATE_PROTECTED_BIT bit not set, the buffer must not be bound to a memory object created with a memory type that reports MEMORY_PROPERTY_PROTECTED_BIT
• If buffer was created with DedicatedAllocationBufferCreateInfoNV::dedicatedAllocation equal to TRUE, memory must have been created with DedicatedAllocationMemoryAllocateInfoNV::buffer equal to a buffer handle created with identical creation parameters to buffer and memoryOffset must be zero
• If the value of ExportMemoryAllocateInfo::handleTypes used to allocate memory is not 0, it must include at least one of the handles set in ExternalMemoryBufferCreateInfo::handleTypes when buffer was created
• If memory was created by a memory import operation, that is not ImportAndroidHardwareBufferInfoANDROID with a non-NULL buffer value, the external handle type of the imported memory must also have been set in ExternalMemoryBufferCreateInfo::handleTypes when buffer was created
• If memory was created with the ImportAndroidHardwareBufferInfoANDROID memory import operation with a non-NULL buffer value, EXTERNAL_MEMORY_HANDLE_TYPE_ANDROID_HARDWARE_BUFFER_BIT_ANDROID must also have been set in ExternalMemoryBufferCreateInfo::handleTypes when buffer was created
• If the PhysicalDeviceBufferDeviceAddressFeatures::bufferDeviceAddress feature is enabled and buffer was created with the BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT bit set, memory must have been allocated with the MEMORY_ALLOCATE_DEVICE_ADDRESS_BIT bit set

Valid Usage (Implicit)

• device must be a valid Device handle

• buffer must be a valid Buffer handle
• memory must be a valid DeviceMemory handle
• buffer must have been created, allocated, or retrieved from device
• memory must have been created, allocated, or retrieved from device

Host Synchronization

• Host access to buffer must be externally synchronized

Return Codes

Success

• SUCCESS

Failure

• ERROR_OUT_OF_HOST_MEMORY
• ERROR_OUT_OF_DEVICE_MEMORY
• ERROR_INVALID_OPAQUE_CAPTURE_ADDRESS_KHR

=> Device

device is the logical device that owns the image.

-> Image

image is the image to query.

-> io MemoryRequirements

vkGetImageMemoryRequirements - Returns the memory requirements for specified Vulkan object

Valid Usage

• image must not have been created with the IMAGE_CREATE_DISJOINT_BIT flag set

• If image was created with the EXTERNAL_MEMORY_HANDLE_TYPE_ANDROID_HARDWARE_BUFFER_BIT_ANDROID external memory handle type, then image must be bound to memory

Valid Usage (Implicit)

• device must be a valid Device handle

• image must be a valid Image handle
• pMemoryRequirements must be a valid pointer to a MemoryRequirements structure
• image must have been created, allocated, or retrieved from device

Arguments

:: forall io. MonadIO io

=> Device

device is the logical device that owns the image and memory.

-> Image

image is the image.

-> DeviceMemory

memory is the DeviceMemory object describing the device memory to attach.

-> ("memoryOffset" ::: DeviceSize)

vkBindImageMemory - Bind device memory to an image object

Description

bindImageMemory is equivalent to passing the same parameters through BindImageMemoryInfo to bindImageMemory2.

Valid Usage

• image must not already be backed by a memory object

• image must not have been created with any sparse memory binding flags
• memoryOffset must be less than the size of memory
• If image requires a dedicated allocation (as reported by getImageMemoryRequirements2 in MemoryDedicatedRequirements::requiresDedicatedAllocation for image), memory must have been created with MemoryDedicatedAllocateInfo::image equal to image
• If the dedicated allocation image aliasing feature is not enabled, and the MemoryAllocateInfo provided when memory was allocated included a MemoryDedicatedAllocateInfo structure in its pNext chain, and MemoryDedicatedAllocateInfo::image was not NULL_HANDLE, then image must equal MemoryDedicatedAllocateInfo::image and memoryOffset must be zero
• If the dedicated allocation image aliasing feature is enabled, and the MemoryAllocateInfo provided when memory was allocated included a MemoryDedicatedAllocateInfo structure in its pNext chain, and MemoryDedicatedAllocateInfo::image was not NULL_HANDLE, then memoryOffset must be zero, and image must be either equal to MemoryDedicatedAllocateInfo::image or an image that was created using the same parameters in ImageCreateInfo, with the exception that extent and arrayLayers may differ subject to the following restrictions: every dimension in the extent parameter of the image being bound must be equal to or smaller than the original image for which the allocation was created; and the arrayLayers parameter of the image being bound must be equal to or smaller than the original image for which the allocation was created
• If image was created with the IMAGE_CREATE_PROTECTED_BIT bit set, the image must be bound to a memory object allocated with a memory type that reports MEMORY_PROPERTY_PROTECTED_BIT
• If image was created with the IMAGE_CREATE_PROTECTED_BIT bit not set, the image must not be bound to a memory object created with a memory type that reports MEMORY_PROPERTY_PROTECTED_BIT

• memory must have been allocated using one of the memory types allowed in the memoryTypeBits member of the MemoryRequirements structure returned from a call to getImageMemoryRequirements with image

Fields

• size :: DeviceSize

  size is the size, in bytes, of the memory allocation required for the resource.

• alignment :: DeviceSize

  alignment is the alignment, in bytes, of the offset within the allocation required for the resource.

• memoryTypeBits :: Word32

  memoryTypeBits is a bitmask and contains one bit set for every supported memory type for the resource. Bit i is set if and only if the memory type i in the PhysicalDeviceMemoryProperties structure for the physical device is supported for the resource.
