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.
