C Specification

To get memory usage information for a command pool object, call:

// Provided by VKSC_VERSION_1_0
void vkGetCommandPoolMemoryConsumption(
    VkDevice                                    device,
    VkCommandPool                               commandPool,
    VkCommandBuffer                             commandBuffer,
    VkCommandPoolMemoryConsumption*             pConsumption);

Parameters

  • device is the logical device that owns the command pool.

  • commandPool is the command pool from which to query the memory usage.

  • commandBuffer is an optional command buffer from which to query the memory usage.

  • pConsumption is a pointer to a VkCommandPoolMemoryConsumption structure where the memory usage is written.

Description

Valid Usage (Implicit)

  • VUID-vkGetCommandPoolMemoryConsumption-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkGetCommandPoolMemoryConsumption-commandPool-parameter
    commandPool must be a valid VkCommandPool handle

  • VUID-vkGetCommandPoolMemoryConsumption-commandBuffer-parameter
    If commandBuffer is not NULL, commandBuffer must be a valid VkCommandBuffer handle

  • VUID-vkGetCommandPoolMemoryConsumption-pConsumption-parameter
    pConsumption must be a valid pointer to a VkCommandPoolMemoryConsumption structure

  • VUID-vkGetCommandPoolMemoryConsumption-commandPool-parent
    commandPool must have been created, allocated, or retrieved from device

  • VUID-vkGetCommandPoolMemoryConsumption-commandBuffer-parent
    If commandBuffer is a valid handle, it must have been created, allocated, or retrieved from commandPool

Host Synchronization

  • Host access to commandPool must be externally synchronized

  • Host access to commandBuffer must be externally synchronized
