Function Prototype

vkCmdBeginGpaSessionAMD

Begin a GPA session

To begin a GPA session, call:

VkResult vkCmdBeginGpaSessionAMD(
    VkCommandBuffer commandBuffer,
    VkGpaSessionAMD                   gpaSession);
  • commandBuffer is the command buffer into which the command will be recorded.
  • gpaSession is the handle of the GPA session to begin.

Valid Usage

VUID-vkCmdBeginGpaSessionAMD-gpaSession-12409

If gpaSession has been used previously to begin and end a session, vkResetGpaSessionAMD must have first been called

VUID-vkCmdBeginGpaSessionAMD-commandBuffer-12410

If another GPA session has been started with vkCmdBeginGpaSessionAMD in commandBuffer, it must have been ended using vkCmdEndGpaSessionAMD before this call

VUID-vkCmdBeginGpaSessionAMD-commandBuffer-cmdpool

The VkCommandPool that commandBuffer was allocated from must support VK_QUEUE_COMPUTE_BIT, or VK_QUEUE_GRAPHICS_BIT operations

VUID-vkCmdBeginGpaSessionAMD-suspended

This command must not be called between suspended render pass instances

VUID-vkCmdBeginGpaSessionAMD-videocoding

This command must only be called outside of a video coding scope

VUID-vkCmdBeginGpaSessionAMD-commonparent

Both of commandBuffer, and gpaSession must have been created, allocated, or retrieved from the same VkDevice
