Function Prototype

vkCmdBeginGpaSampleAMD

Beginning a sample

To begin a GPA sample, call:

VkResult vkCmdBeginGpaSampleAMD(
    VkCommandBuffer commandBuffer,
    VkGpaSessionAMD                   gpaSession,
    const VkGpaSampleBeginInfoAMD*    pGpaSampleBeginInfo,
    uint32_t*                         pSampleID);
  • commandBuffer is the command buffer into which the command will be recorded.
  • gpaSession is the handle of the GPA session to record the sample.
  • pGpaSampleBeginInfo is a pointer to a VkGpaSampleBeginInfoAMD structure describing the sample parameters.
  • pSampleID is the unique sample ID returned for this sample.

Valid Usage (Implicit)

VUID-vkCmdBeginGpaSampleAMD-pGpaSampleBeginInfo-parameter

pGpaSampleBeginInfo must be a valid pointer to a valid VkGpaSampleBeginInfoAMD structure

VUID-vkCmdBeginGpaSampleAMD-pSampleID-parameter

pSampleID must be a valid pointer to a uint32_t value

VUID-vkCmdBeginGpaSampleAMD-commandBuffer-cmdpool

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

VUID-vkCmdBeginGpaSampleAMD-suspended

This command must not be called between suspended render pass instances

VUID-vkCmdBeginGpaSampleAMD-videocoding

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

VUID-vkCmdBeginGpaSampleAMD-commonparent

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

Host Synchronization

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