VkPhysicalDeviceMaintenance8FeaturesKHR

The VkPhysicalDeviceMaintenance8FeaturesKHR structure is defined as:

typedef struct VkPhysicalDeviceMaintenance8FeaturesKHR {
    VkStructureType sType;
    void* pNext;
    VkBool32 maintenance8;
} VkPhysicalDeviceMaintenance8FeaturesKHR;

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

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.
