C Specification

The structure describing source and destination memory regions, VkCopyMemoryIndirectCommandKHR is defined as:

// Provided by VK_KHR_copy_memory_indirect
typedef struct VkCopyMemoryIndirectCommandKHR {
    VkDeviceAddress    srcAddress;
    VkDeviceAddress    dstAddress;
    VkDeviceSize       size;
} VkCopyMemoryIndirectCommandKHR;
// Provided by VK_NV_copy_memory_indirect
// Equivalent to VkCopyMemoryIndirectCommandKHR
typedef VkCopyMemoryIndirectCommandKHR VkCopyMemoryIndirectCommandNV;

Members

  • srcAddress is the starting address of the source device memory to copy from.

  • dstAddress is the starting address of the destination device memory to copy to.

  • size is the size of the copy in bytes.

Description

Valid Usage

  • VUID-VkCopyMemoryIndirectCommandKHR-srcAddress-10958
    The srcAddress must be 4 byte aligned

  • VUID-VkCopyMemoryIndirectCommandKHR-dstAddress-10959
    The dstAddress must be 4 byte aligned

  • VUID-VkCopyMemoryIndirectCommandKHR-size-10960
    The size must be 4 byte aligned

  • VUID-VkCopyMemoryIndirectCommandKHR-srcAddress-10961
    The memory in range [srcAddress, srcAddress + size - 1] must be within the bounds of the memory allocation backing srcAddress

  • VUID-VkCopyMemoryIndirectCommandKHR-dstAddress-10962
    The memory in range [dstAddress, dstAddress + size - 1] must be within the bounds of the memory allocation backing dstAddress

  • VUID-VkCopyMemoryIndirectCommandKHR-srcAddress-12211
    The range of memory defined by srcAddress and size must be a device address range allocated to the application from a buffer created with the VK_BUFFER_USAGE_TRANSFER_SRC_BIT usage flag set

  • VUID-VkCopyMemoryIndirectCommandKHR-dstAddress-12212
    The range of memory defined by dstAddress and size must be a device address range allocated to the application from a buffer created with the VK_BUFFER_USAGE_TRANSFER_DST_BIT usage flag set

Valid Usage (Implicit)

  • VUID-VkCopyMemoryIndirectCommandKHR-srcAddress-parameter
    srcAddress must be a valid VkDeviceAddress value

  • VUID-VkCopyMemoryIndirectCommandKHR-dstAddress-parameter
    dstAddress must be a valid VkDeviceAddress value
