VkPhysicalDeviceMaintenance8FeaturesKHR(3)

# VkPhysicalDeviceMaintenance8FeaturesKHR(3) Manual Page

## Name

VkPhysicalDeviceMaintenance8FeaturesKHR - Structure describing whether the implementation supports maintenance8 functionality

Loading… please wait.

## C Specification

The `VkPhysicalDeviceMaintenance8FeaturesKHR` structure is defined as:

    // Provided by VK_KHR_maintenance8
    typedef struct VkPhysicalDeviceMaintenance8FeaturesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           maintenance8;
    } VkPhysicalDeviceMaintenance8FeaturesKHR;

## Members

This structure describes the following feature:

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

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

- `maintenance8` indicates that the implementation supports the following:

  - Allow copies between depth/stencil and “matching” color attachments

  - Allow `dstCache` in `vkMergePipelineCaches` to be implicitly synchronized.

  - Require src/dst sync scopes to work when doing queue family ownership transfers

  - Support `Offset` (as an alternative to `ConstOffset`) image operand in texture sampling and fetch operations

  - Use the SPIR-V definition of OpSRem and OpSMod, making these operations produce well-defined results for negative operands

  - Loosen layer restrictions when blitting from 3D images to other image types

  - Add space for an additional 64 access flags for use with VkMemoryBarrier2, VkBufferMemoryBarrier2, and VkImageMemoryBarrier2

## Description

If the `VkPhysicalDeviceMaintenance8FeaturesKHR` structure is included in the `pNext` chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by `VkPhysicalDeviceMaintenance8FeaturesKHR`, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the `pNext` chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceMaintenance8FeaturesKHR-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_MAINTENANCE_8_FEATURES_KHR
