vkGetBufferOpaqueCaptureAddress - Query an opaque capture address of a buffer

Parameters

• device is the logical device that the buffer was created on.

• pInfo is a pointer to a BufferDeviceAddressInfo structure specifying the buffer to retrieve an address for.

Description

The 64-bit return value is an opaque capture address of the start of pInfo->buffer.

If the buffer was created with a non-zero value of BufferOpaqueCaptureAddressCreateInfo::opaqueCaptureAddress the return value must be the same address.

Valid Usage

• The bufferDeviceAddress feature must be enabled

• If device was created with multiple physical devices, then the bufferDeviceAddressMultiDevice feature must be enabled

Valid Usage (Implicit)

• device must be a valid Device handle

• pInfo must be a valid pointer to a valid BufferDeviceAddressInfo structure

vkGetBufferDeviceAddress - Query an address of a buffer

Parameters

• device is the logical device that the buffer was created on.

• pInfo is a pointer to a BufferDeviceAddressInfo structure specifying the buffer to retrieve an address for.

Description

The 64-bit return value is an address of the start of pInfo->buffer. The address range starting at this value and whose size is the size of the buffer can be used in a shader to access the memory bound to that buffer, using the SPV_KHR_physical_storage_buffer extension or the equivalent SPV_EXT_physical_storage_buffer extension and the PhysicalStorageBuffer storage class. For example, this value can be stored in a uniform buffer, and the shader can read the value from the uniform buffer and use it to do a dependent read/write to this buffer. A value of zero is reserved as a “null” pointer and must not be returned as a valid buffer device address. All loads, stores, and atomics in a shader through PhysicalStorageBuffer pointers must access addresses in the address range of some buffer.

If the buffer was created with a non-zero value of BufferOpaqueCaptureAddressCreateInfo::opaqueCaptureAddress or BufferDeviceAddressCreateInfoEXT::deviceAddress the return value will be the same address that was returned at capture time.

Valid Usage

• The bufferDeviceAddress or ::bufferDeviceAddress feature must be enabled

• If device was created with multiple physical devices, then the bufferDeviceAddressMultiDevice or ::bufferDeviceAddressMultiDevice feature must be enabled

Valid Usage (Implicit)

• device must be a valid Device handle

• pInfo must be a valid pointer to a valid BufferDeviceAddressInfo structure

vkGetDeviceMemoryOpaqueCaptureAddress - Query an opaque capture address of a memory object

Parameters

• device is the logical device that the memory object was allocated on.

• pInfo is a pointer to a DeviceMemoryOpaqueCaptureAddressInfo structure specifying the memory object to retrieve an address for.

Description

The 64-bit return value is an opaque address representing the start of pInfo->memory.

If the memory object was allocated with a non-zero value of MemoryOpaqueCaptureAddressAllocateInfo::opaqueCaptureAddress, the return value must be the same address.

Note

The expected usage for these opaque addresses is only for trace capture/replay tools to store these addresses in a trace and subsequently specify them during replay.

Valid Usage

• The bufferDeviceAddress feature must be enabled

• If device was created with multiple physical devices, then the bufferDeviceAddressMultiDevice feature must be enabled

Valid Usage (Implicit)

• device must be a valid Device handle

• pInfo must be a valid pointer to a valid DeviceMemoryOpaqueCaptureAddressInfo structure

VkPhysicalDeviceBufferDeviceAddressFeatures - Structure describing buffer address features that can be supported by an implementation

Members

The members of the PhysicalDeviceBufferDeviceAddressFeatures structure describe the following features:

Description

Note

bufferDeviceAddressMultiDevice exists to allow certain legacy platforms to be able to support bufferDeviceAddress without needing to support shared GPU virtual addresses for multi-device configurations.

See getBufferDeviceAddress for more information.

If the PhysicalDeviceBufferDeviceAddressFeatures structure is included in the pNext chain of PhysicalDeviceFeatures2, it is filled with values indicating whether the feature is supported. PhysicalDeviceBufferDeviceAddressFeatures can also be included in the pNext chain of DeviceCreateInfo to enable features.

Valid Usage (Implicit)

VkBufferDeviceAddressInfo - Structure specifying the buffer to query an address for

Valid Usage

• If buffer is non-sparse and was not created with the BUFFER_CREATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT flag, then it must be bound completely and contiguously to a single DeviceMemory object

• buffer must have been created with BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_BUFFER_DEVICE_ADDRESS_INFO

• pNext must be NULL
• buffer must be a valid Buffer handle

VkBufferOpaqueCaptureAddressCreateInfo - Request a specific address for a buffer

Description

If opaqueCaptureAddress is zero, no specific address is requested.

If opaqueCaptureAddress is not zero, then it should be an address retrieved from getBufferOpaqueCaptureAddress for an identically created buffer on the same implementation.

If this structure is not present, it is as if opaqueCaptureAddress is zero.

Apps should avoid creating buffers with app-provided addresses and implementation-provided addresses in the same process, to reduce the likelihood of ERROR_INVALID_OPAQUE_CAPTURE_ADDRESS errors.

Note

The expected usage for this is that a trace capture/replay tool will add the BUFFER_CREATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT flag to all buffers that use BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT, and during capture will save the queried opaque device addresses in the trace. During replay, the buffers will be created specifying the original address so any address values stored in the trace data will remain valid.

Implementations are expected to separate such buffers in the GPU address space so normal allocations will avoid using these addresses. Apps/tools should avoid mixing app-provided and implementation-provided addresses for buffers created with BUFFER_CREATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT, to avoid address space allocation conflicts.

Valid Usage (Implicit)

VkMemoryOpaqueCaptureAddressAllocateInfo - Request a specific address for a memory allocation

Description

If opaqueCaptureAddress is zero, no specific address is requested.

If opaqueCaptureAddress is not zero, it should be an address retrieved from getDeviceMemoryOpaqueCaptureAddress on an identically created memory allocation on the same implementation.

Note

In most cases, it is expected that a non-zero opaqueAddress is an address retrieved from getDeviceMemoryOpaqueCaptureAddress on an identically created memory allocation. If this is not the case, it likely that ERROR_INVALID_OPAQUE_CAPTURE_ADDRESS errors will occur.

This is, however, not a strict requirement because trace capture/replay tools may need to adjust memory allocation parameters for imported memory.

If this structure is not present, it is as if opaqueCaptureAddress is zero.

VkStructureType - Vulkan structure types (stype)

Description

Each value corresponds to a particular structure with a sType member with a matching name. As a general rule, the name of each StructureType value is obtained by taking the name of the structure, stripping the leading Vk, prefixing each capital letter with _, converting the entire resulting string to upper case, and prefixing it with VK_STRUCTURE_TYPE_. For example, structures of type ImageCreateInfo correspond to a StructureType of STRUCTURE_TYPE_IMAGE_CREATE_INFO, and thus its sType member must equal that when it is passed to the API.

The values STRUCTURE_TYPE_LOADER_INSTANCE_CREATE_INFO and STRUCTURE_TYPE_LOADER_DEVICE_CREATE_INFO are reserved for internal use by the loader, and do not have corresponding Vulkan structures in this Specification.

VkResult - Vulkan command return codes

Description

If a command returns a run time error, unless otherwise specified any output parameters will have undefined contents, except that if the output parameter is a structure with sType and pNext fields, those fields will be unmodified. Any structures chained from pNext will also have undefined contents, except that sType and pNext will be unmodified.

Out of memory errors do not damage any currently existing Vulkan objects. Objects that have already been successfully created can still be used by the application.

ERROR_UNKNOWN will be returned by an implementation when an unexpected error occurs that cannot be attributed to valid behavior of the application and implementation.

Note

If ERROR_UNKNOWN is received, the application should be checked against the latest validation layers to verify correct behavior as much as possible. If no issues are identified it could be an implementation issue, and the implementor should be contacted for support.

This error should not be expected from any command if application behavior is valid, and if the implementation is bug-free, but it can be returned by any error returning command when that is not the case.

Performance-critical commands generally do not have return codes. If a run time error occurs in such commands, the implementation will defer reporting the error until a specified point. For commands that record into command buffers (vkCmd*) run time errors are reported by endCommandBuffer.
