## Name

VkValidationFeaturesEXT - Specify validation features to enable or disable for a Vulkan instance

Loading… please wait.

## C Specification

When creating a Vulkan instance for which you wish to enable or disable specific validation features, add a VkValidationFeaturesEXT structure to the `pNext` chain of the VkInstanceCreateInfo structure, specifying the features to be enabled or disabled.

    // Provided by VK_EXT_validation_features
    typedef struct VkValidationFeaturesEXT {
        VkStructureType                         sType;
        const void*                             pNext;
        uint32_t                                enabledValidationFeatureCount;
        const VkValidationFeatureEnableEXT*     pEnabledValidationFeatures;
        uint32_t                                disabledValidationFeatureCount;
        const VkValidationFeatureDisableEXT*    pDisabledValidationFeatures;
    } VkValidationFeaturesEXT;

## Members

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

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

- `enabledValidationFeatureCount` is the number of features to enable.

- `pEnabledValidationFeatures` is a pointer to an array of VkValidationFeatureEnableEXT values specifying the validation features to be enabled.

- `disabledValidationFeatureCount` is the number of features to disable.

- `pDisabledValidationFeatures` is a pointer to an array of VkValidationFeatureDisableEXT values specifying the validation features to be disabled.

## Description

Valid Usage

- VUID-VkValidationFeaturesEXT-pEnabledValidationFeatures-02967
  If the `pEnabledValidationFeatures` array contains `VK_VALIDATION_FEATURE_ENABLE_GPU_ASSISTED_RESERVE_BINDING_SLOT_EXT`, then it must also contain `VK_VALIDATION_FEATURE_ENABLE_GPU_ASSISTED_EXT` or `VK_VALIDATION_FEATURE_ENABLE_DEBUG_PRINTF_EXT`

Valid Usage (Implicit)

- VUID-VkValidationFeaturesEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_VALIDATION_FEATURES_EXT`

- VUID-VkValidationFeaturesEXT-pEnabledValidationFeatures-parameter
  If `enabledValidationFeatureCount` is not `0`, `pEnabledValidationFeatures` must be a valid pointer to an array of `enabledValidationFeatureCount` valid VkValidationFeatureEnableEXT values

- VUID-VkValidationFeaturesEXT-pDisabledValidationFeatures-parameter
  If `disabledValidationFeatureCount` is not `0`, `pDisabledValidationFeatures` must be a valid pointer to an array of `disabledValidationFeatureCount` valid VkValidationFeatureDisableEXT values
