vkEnumerateDeviceExtensionProperties

To query the extensions available to a given physical device, call:

VkResult vkEnumerateDeviceExtensionProperties(
    VkPhysicalDevice physicalDevice,
    const char* pLayerName,
    uint32_t* pPropertyCount,
    VkExtensionProperties* pProperties);

pub fn enumerate_device_extension_properties(
    physical_device: vk::PhysicalDevice,
    p_layer_name: *const c_char,
    p_property_count: *mut u32,
    p_properties: *mut vk::ExtensionProperties,
) -> vk::Result;

• physicalDevice is the physical device that will be queried.
• pLayerName is either NULL or a pointer to a null-terminated UTF-8 string naming the layer to retrieve extensions from.
• pPropertyCount is a pointer to an integer related to the number of extension properties available or queried, and is treated in the same fashion as the vkEnumerateInstanceExtensionProperties::pPropertyCount parameter.
• pProperties is either NULL or a pointer to an array of VkExtensionProperties structures.

When pLayerName parameter is NULL, only extensions provided by the Vulkan implementation or by implicitly enabled layers are returned. When pLayerName is the name of a layer, the device extensions provided by that layer are returned.

Implementations must not advertise any pair of extensions that cannot be enabled together due to behavioral differences, or any extension that cannot be enabled against the advertised version.

If the VK_KHR_ray_tracing_pipeline extension is advertised as supported by this query, the VK_KHR_pipeline_library extension must also be supported.

If the VK_EXT_descriptor_heap extension is advertised as supported by this query, the VK_KHR_shader_untyped_pointers extension must also be supported.

Implementations claiming support for the Roadmap 2022 profile must advertise the VK_KHR_global_priority extension in pProperties.

Implementations claiming support for the Roadmap 2024 profile must advertise the following extensions in pProperties:

• VK_KHR_dynamic_rendering_local_read
• VK_KHR_load_store_op_none
• VK_KHR_shader_quad_control
• VK_KHR_shader_maximal_reconvergence
• VK_KHR_shader_subgroup_uniform_control_flow
• VK_KHR_shader_subgroup_rotate
• VK_KHR_shader_float_controls2
• VK_KHR_shader_expect_assume
• VK_KHR_line_rasterization
• VK_KHR_vertex_attribute_divisor
• VK_KHR_index_type_uint8
• VK_KHR_map_memory2
• VK_KHR_maintenance5
• VK_KHR_push_descriptor
