# VkImageConstraintsInfoFlagBitsFUCHSIA(3) Manual Page

## Name

VkImageConstraintsInfoFlagBitsFUCHSIA - Bitmask specifying image constraints flags

Loading… please wait.

## 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,
        VK_IMAGE_CONSTRAINTS_INFO_CPU_WRITE_RARELY_FUCHSIA = 0x00000004,
        VK_IMAGE_CONSTRAINTS_INFO_CPU_WRITE_OFTEN_FUCHSIA = 0x00000008,
        VK_IMAGE_CONSTRAINTS_INFO_PROTECTED_OPTIONAL_FUCHSIA = 0x00000010,
    } VkImageConstraintsInfoFlagBitsFUCHSIA;

## 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:

- `VK_IMAGE_CONSTRAINTS_INFO_CPU_READ_RARELY_FUCHSIA`

- `VK_IMAGE_CONSTRAINTS_INFO_CPU_READ_OFTEN_FUCHSIA`

- `VK_IMAGE_CONSTRAINTS_INFO_CPU_WRITE_RARELY_FUCHSIA`

- `VK_IMAGE_CONSTRAINTS_INFO_CPU_WRITE_OFTEN_FUCHSIA`

For protected memory:

- `VK_IMAGE_CONSTRAINTS_INFO_PROTECTED_OPTIONAL_FUCHSIA` specifies that protected memory is optional for the buffer collection.

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