C Specification

Bits which can be set in VkImageConstraintsInfoFlagBitsFUCHSIA::flags include:

// Provided by VK_FUCHSIA_buffer_collection
typedef enum VkImageConstraintsInfoFlagBitsFUCHSIA {
    VK_IMAGE_CONSTRAINTS_INFO_CPU_READ_RARELY_FUCHSIA = 0x00000001,
    VK_IMAGE_CONSTRAINTS_INFO_CPU_READ_OFTEN_FUCHSIA = 0x00000002,

Description

General hints about the type of memory that should be allocated by Sysmem based on the expected usage of the images in the buffer collection include:

For protected memory:

Note that if all participants in the buffer collection (Vulkan or otherwise) specify that protected memory is optional, Sysmem will not allocate protected memory.
