Function Prototype

vkCopyMemoryToMicromapEXT

Deserialize a micromap on the host

To copy host accessible memory to a micromap, call:

VkResult vkCopyMemoryToMicromapEXT(
    VkDevice device,
    VkDeferredOperationKHR deferredOperation,
    const VkCopyMemoryToMicromapInfoEXT* pInfo);

This command fulfills the same task as vkCmdCopyMemoryToMicromapEXT but is executed by the host.

This command can accept micromaps produced by either vkCmdCopyMicromapToMemoryEXT or vkCopyMicromapToMemoryEXT.

Valid Usage

VUID-vkCopyMemoryToMicromapEXT-deferredOperation-03678

Any previous deferred operation that was associated with deferredOperation must be complete

VUID-vkCopyMemoryToMicromapEXT-pInfo-07563

pInfo→src.hostAddress must be a valid host pointer

VUID-vkCopyMemoryToMicromapEXT-pInfo-07564

pInfo→src.hostAddress must be aligned to 16 bytes

VUID-vkCopyMemoryToMicromapEXT-buffer-07565

The buffer used to create pInfo→dst must be bound to host-visible device memory

VUID-vkCopyMemoryToMicromapEXT-buffer-07567

The buffer used to create pInfo→dst must be bound to memory that was not allocated with multiple instances

Valid Usage (Implicit)

VUID-vkCopyMemoryToMicromapEXT-deferredOperation-parameter

If deferredOperation is not VK_NULL_HANDLE, deferredOperation must be a valid VkDeferredOperationKHR handle

VUID-vkCopyMemoryToMicromapEXT-pInfo-parameter

pInfo must be a valid pointer to a valid VkCopyMemoryToMicromapInfoEXT structure

VUID-vkCopyMemoryToMicromapEXT-deferredOperation-parent

If deferredOperation is a valid handle, it must have been created, allocated, or retrieved from device
