public class KHRDeviceGroup
extends java.lang.Object

This extension provides functionality to use a logical device that consists of multiple physical devices, as created with the VK_KHR_device_group_creation extension. A device group can allocate memory across the subdevices, bind memory from one subdevice to a resource on another subdevice, record command buffers where some work executes on an arbitrary subset of the subdevices, and potentially present a swapchain image from one or more subdevices.

Promotion to Vulkan 1.1

The following enums, types and commands are included as interactions with VK_KHR_swapchain:

• STRUCTURE_TYPE_DEVICE_GROUP_PRESENT_CAPABILITIES_KHR
• STRUCTURE_TYPE_IMAGE_SWAPCHAIN_CREATE_INFO_KHR
• STRUCTURE_TYPE_BIND_IMAGE_MEMORY_SWAPCHAIN_INFO_KHR
• STRUCTURE_TYPE_ACQUIRE_NEXT_IMAGE_INFO_KHR
• STRUCTURE_TYPE_DEVICE_GROUP_PRESENT_INFO_KHR
• STRUCTURE_TYPE_DEVICE_GROUP_SWAPCHAIN_CREATE_INFO_KHR
• SWAPCHAIN_CREATE_SPLIT_INSTANCE_BIND_REGIONS_BIT_KHR
• VkDeviceGroupPresentModeFlagBitsKHR
• VkDeviceGroupPresentCapabilitiesKHR
• VkImageSwapchainCreateInfoKHR
• VkBindImageMemorySwapchainInfoKHR
• VkAcquireNextImageInfoKHR
• VkDeviceGroupPresentInfoKHR
• VkDeviceGroupSwapchainCreateInfoKHR
• GetDeviceGroupPresentCapabilitiesKHR
• GetDeviceGroupSurfacePresentModesKHR
• GetPhysicalDevicePresentRectanglesKHR
• AcquireNextImage2KHR

If Vulkan 1.1 and VK_KHR_swapchain are supported, these are included by VK_KHR_swapchain.

The base functionality in this extension is included in core Vulkan 1.1, with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.

                                                           long pRects)

Unsafe version of: GetPhysicalDevicePresentRectanglesKHR

Parameters:

vkGetPhysicalDevicePresentRectanglesKHR

public static int vkGetPhysicalDevicePresentRectanglesKHR(VkPhysicalDevice physicalDevice,
                                                          long surface,
                                                          java.nio.IntBuffer pRectCount,
                                                          @Nullable
                                                          VkRect2D.Buffer pRects)

Query present rectangles for a surface on a physical device.

C Specification

When using DEVICE_GROUP_PRESENT_MODE_LOCAL_MULTI_DEVICE_BIT_KHR, the application may need to know which regions of the surface are used when presenting locally on each physical device. Presentation of swapchain images to this surface need only have valid contents in the regions returned by this command.

To query a set of rectangles used in presentation on the physical device, call:

 VkResult vkGetPhysicalDevicePresentRectanglesKHR(
     VkPhysicalDevice                            physicalDevice,
     VkSurfaceKHR                                surface,
     uint32_t*                                   pRectCount,
     VkRect2D*                                   pRects);

Description

If pRects is NULL, then the number of rectangles used when presenting the given surface is returned in pRectCount. Otherwise, pRectCount must point to a variable set by the user to the number of elements in the pRects array, and on return the variable is overwritten with the number of structures actually written to pRects. If the value of pRectCount is less than the number of rectangles, at most pRectCount structures will be written. If pRectCount is smaller than the number of rectangles used for the given surface, INCOMPLETE will be returned instead of SUCCESS to indicate that not all the available values were returned.

The values returned by this command are not invariant, and may change in response to the surface being moved, resized, or occluded.

The rectangles returned by this command must not overlap.

Valid Usage (Implicit)

• physicalDevice must be a valid VkPhysicalDevice handle
• surface must be a valid VkSurfaceKHR handle
• pRectCount must be a valid pointer to a uint32_t value
• If the value referenced by pRectCount is not 0, and pRects is not NULL, pRects must be a valid pointer to an array of pRectCount VkRect2D structures
• Both of physicalDevice, and surface must have been created, allocated, or retrieved from the same VkInstance

Host Synchronization

• Host access to surface must be externally synchronized

Return Codes

On success, this command returns

• SUCCESS
• INCOMPLETE

On failure, this command returns

• ERROR_OUT_OF_HOST_MEMORY
• ERROR_OUT_OF_DEVICE_MEMORY

                                         java.nio.IntBuffer pImageIndex)

Retrieve the index of the next available presentable image.

C Specification

To acquire an available presentable image to use, and retrieve the index of that image, call:

 VkResult vkAcquireNextImage2KHR(
     VkDevice                                    device,
     const VkAcquireNextImageInfoKHR*            pAcquireInfo,
     uint32_t*                                   pImageIndex);

Valid Usage

• If the number of currently acquired images is greater than the difference between the number of images in the swapchain member of pAcquireInfo and the value of VkSurfaceCapabilitiesKHR::minImageCount as returned by a call to GetPhysicalDeviceSurfaceCapabilities2KHR with the surface used to create swapchain, the timeout member of pAcquireInfo must not be UINT64_MAX

Valid Usage (Implicit)

• device must be a valid VkDevice handle
• pAcquireInfo must be a valid pointer to a valid VkAcquireNextImageInfoKHR structure
• pImageIndex must be a valid pointer to a uint32_t value

Return Codes

On success, this command returns
