C Specification

To record an indirect mesh tasks drawing command, call:

// Provided by VK_KHR_device_address_commands with VK_EXT_mesh_shader
void vkCmdDrawMeshTasksIndirect2EXT(
    VkCommandBuffer                             commandBuffer,
    const VkDrawIndirect2InfoKHR*               pInfo);

Parameters

  • commandBuffer is the command buffer into which the command is recorded.

  • pInfo is a pointer to a VkDrawIndirect2InfoKHR structure defining parameters of this command.

Description

vkCmdDrawMeshTasksIndirect2EXT behaves similarly to vkCmdDrawMeshTasksEXT except that the parameters are read by the device from an address range during execution. pInfo->drawCount draws are executed by the command, with parameters taken from pInfo->addressRange starting at addressRange.address and increasing by addressRange.stride bytes for each successive draw. The parameters of each draw are encoded in an array of VkDrawMeshTasksIndirectCommandEXT structures.

Valid Usage
Valid Usage (Implicit)
  • VUID-vkCmdDrawMeshTasksIndirect2EXT-commandBuffer-parameter
    commandBuffer must be a valid VkCommandBuffer handle

  • VUID-vkCmdDrawMeshTasksIndirect2EXT-pInfo-parameter
    pInfo must be a valid pointer to a valid VkDrawIndirect2InfoKHR structure

  • VUID-vkCmdDrawMeshTasksIndirect2EXT-commandBuffer-recording
    commandBuffer must be in the recording state

  • VUID-vkCmdDrawMeshTasksIndirect2EXT-commandBuffer-cmdpool
    The VkCommandPool that commandBuffer was allocated from must support VK_QUEUE_GRAPHICS_BIT operations

  • VUID-vkCmdDrawMeshTasksIndirect2EXT-renderpass
    This command must only be called inside of a render pass instance

  • VUID-vkCmdDrawMeshTasksIndirect2EXT-suspended
    This command must not be called between suspended render pass instances

  • VUID-vkCmdDrawMeshTasksIndirect2EXT-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
