vkCmdCopyMicromapEXT(3)

C Specification

To copy a micromap call:

// Provided by VK_EXT_opacity_micromap
void vkCmdCopyMicromapEXT(
    VkCommandBuffer                             commandBuffer,
    const VkCopyMicromapInfoEXT*                pInfo);

Parameters

commandBuffer is the command buffer into which the command will be recorded.
pInfo is a pointer to a VkCopyMicromapInfoEXT structure defining the copy operation.

Description

This command copies the pInfo->src micromap to the pInfo->dst micromap in the manner specified by pInfo->mode.

Accesses to pInfo->src and pInfo->dst must be synchronized with the VK_PIPELINE_STAGE_2_MICROMAP_BUILD_BIT_EXT pipeline stage and an access type of VK_ACCESS_2_MICROMAP_READ_BIT_EXT or VK_ACCESS_2_MICROMAP_WRITE_BIT_EXT as appropriate.

Valid Usage

VUID-vkCmdCopyMicromapEXT-buffer-07529
The buffer used to create pInfo->src must be bound to device memory
VUID-vkCmdCopyMicromapEXT-buffer-07530
The buffer used to create pInfo->dst must be bound to device memory

Valid Usage (Implicit)

VUID-vkCmdCopyMicromapEXT-commandBuffer-parameter
commandBuffer must be a valid VkCommandBuffer handle
VUID-vkCmdCopyMicromapEXT-pInfo-parameter
pInfo must be a valid pointer to a valid VkCopyMicromapInfoEXT structure
VUID-vkCmdCopyMicromapEXT-commandBuffer-recording
commandBuffer must be in the recording state
VUID-vkCmdCopyMicromapEXT-commandBuffer-cmdpool
The VkCommandPool that commandBuffer was allocated from must support compute operations
VUID-vkCmdCopyMicromapEXT-renderpass
This command must only be called outside of a render pass instance
VUID-vkCmdCopyMicromapEXT-videocoding
This command must only be called outside of a video coding scope

Host Synchronization

Host access to commandBuffer must be externally synchronized
Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
