## Name

VkDeviceGroupPresentCapabilitiesKHR - Present capabilities from other physical devices

Loading… please wait.

## C Specification

The `VkDeviceGroupPresentCapabilitiesKHR` structure is defined as:

    // Provided by VK_VERSION_1_1 with VK_KHR_swapchain, VK_KHR_device_group with VK_KHR_surface
    typedef struct VkDeviceGroupPresentCapabilitiesKHR {
        VkStructureType                     sType;
        void*                               pNext;
        uint32_t                            presentMask[VK_MAX_DEVICE_GROUP_SIZE];
        VkDeviceGroupPresentModeFlagsKHR    modes;
    } VkDeviceGroupPresentCapabilitiesKHR;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `presentMask` is an array of `VK_MAX_DEVICE_GROUP_SIZE` `uint32_t` masks, where the mask at element i is non-zero if physical device i has a presentation engine, and where bit j is set in element i if physical device i can present swapchain images from physical device j. If element i is non-zero, then bit i must be set.

- `modes` is a bitmask of VkDeviceGroupPresentModeFlagBitsKHR indicating which device group presentation modes are supported.

## Description

`modes` always has `VK_DEVICE_GROUP_PRESENT_MODE_LOCAL_BIT_KHR` set.

The present mode flags are also used when presenting an image, in VkDeviceGroupPresentInfoKHR::`mode`.

If a device group only includes a single physical device, then `modes` must equal `VK_DEVICE_GROUP_PRESENT_MODE_LOCAL_BIT_KHR`.

Valid Usage (Implicit)

- VUID-VkDeviceGroupPresentCapabilitiesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_DEVICE_GROUP_PRESENT_CAPABILITIES_KHR`

- VUID-VkDeviceGroupPresentCapabilitiesKHR-pNext-pNext
  `pNext` must be `NULL`
