# VkPhysicalDeviceMaintenance10PropertiesKHR(3) Manual Page

## Name

VkPhysicalDeviceMaintenance10PropertiesKHR - Structure describing various implementation-defined properties introduced with VK_KHR_maintenance10

Loading… please wait.

## C Specification

The `VkPhysicalDeviceMaintenance10PropertiesKHR` structure is defined as:

    // Provided by VK_KHR_maintenance10
    typedef struct VkPhysicalDeviceMaintenance10PropertiesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           rgba4OpaqueBlackSwizzled;
        VkBool32           resolveSrgbFormatAppliesTransferFunction;
        VkBool32           resolveSrgbFormatSupportsTransferFunctionControl;
    } VkPhysicalDeviceMaintenance10PropertiesKHR;

## Members

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

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

- `rgba4OpaqueBlackSwizzled` indicates whether correct swizzling is applied to the opaque black border color when using either the `VK_FORMAT_B4G4R4A4_UNORM_PACK16` or `VK_FORMAT_R4G4B4A4_UNORM_PACK16` format. If it is `VK_TRUE`, the implementation will correctly produce an opaque black border color with these formats. If it is `VK_FALSE`, the implementation may swap the first channel with the alpha channel for the border color when sampling.

- `resolveSrgbFormatAppliesTransferFunction` indicates whether resolving a multi-sampled sRGB format to single-sampled sRGB by a weighted average converts the samples to linear before averaging. This applies to both attachment resolves in a render pass and standalone resolve commands. If `VK_TRUE`, implementation always converts to linear before averaging unless overridden. If `VK_FALSE`, implementation never converts to linear before averaging unless overridden.

- `resolveSrgbFormatSupportsTransferFunctionControl` indicates whether the implementation supports overriding the default behavior in `resolveSrgbFormatAppliesTransferFunction` in render passes and vkCmdResolveImage2.

## Description

Implementations supporting `maintenance10` should set `resolveSrgbFormatAppliesTransferFunction` to `VK_TRUE`.

If the `VkPhysicalDeviceMaintenance10PropertiesKHR` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceMaintenance10PropertiesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_MAINTENANCE_10_PROPERTIES_KHR`
