C Specification
The VkDeviceGroupPresentCapabilitiesKHR structure is defined as:
typedef struct VkDeviceGroupPresentCapabilitiesKHR {
VkStructureType sType;
const void* pNext;
uint32_t presentMask[VK_MAX_DEVICE_GROUP_SIZE];
VkDeviceGroupPresentModeFlagsKHR modes;
} VkDeviceGroupPresentCapabilitiesKHR;
Members
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to an extension-specific structure. -
presentMaskis an array ofVK_MAX_DEVICE_GROUP_SIZEuint32_tmasks, 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. -
modesis 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.
