Function Prototype

vkCmdPushConstants2KHR

Update the values of push constants
primary / secondary
both
graphics / compute
state

Alternatively, to update push constants, call:

void vkCmdPushConstants2KHR(
    VkCommandBuffer commandBuffer,
    const VkPushConstantsInfoKHR* pPushConstantsInfo);
  • commandBuffer is the command buffer in which the push constant update will be recorded.
  • pPushConstantsInfo is a pointer to a VkPushConstantsInfoKHR structure.

Valid Usage (Implicit)

VUID-vkCmdPushConstants2KHR-pPushConstantsInfo-parameter

pPushConstantsInfo must be a valid pointer to a valid VkPushConstantsInfoKHR structure

VUID-vkCmdPushConstants2KHR-commandBuffer-cmdpool

The VkCommandPool that commandBuffer was allocated from must support graphics, or compute operations

VUID-vkCmdPushConstants2KHR-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 ::
