C Specification

Bits which may be set in VkMemoryHeap::flags, indicating attribute flags for the heap, are:

// Provided by VK_VERSION_1_0
typedef enum VkMemoryHeapFlagBits {
    VK_MEMORY_HEAP_DEVICE_LOCAL_BIT = 0x00000001,
  // Provided by VK_VERSION_1_1
    VK_MEMORY_HEAP_MULTI_INSTANCE_BIT = 0x00000002,
  // Provided by VKSC_VERSION_1_0
    VK_MEMORY_HEAP_SEU_SAFE_BIT = 0x00000004,
} VkMemoryHeapFlagBits;

Description

  • VK_MEMORY_HEAP_DEVICE_LOCAL_BIT specifies that the heap corresponds to device-local memory. Device-local memory may have different performance characteristics than host-local memory, and may support different memory property flags.

  • VK_MEMORY_HEAP_MULTI_INSTANCE_BIT specifies that in a logical device representing more than one physical device, there is a per-physical device instance of the heap memory. By default, an allocation from such a heap will be replicated to each physical device’s instance of the heap.

  • VK_MEMORY_HEAP_SEU_SAFE_BIT specifies that the heap is protected against single event upsets.
