# VkPhysicalDeviceGpaFeaturesAMD(3) Manual Page

## Name

VkPhysicalDeviceGpaFeaturesAMD - Structure describing support for GPU performance API

## C Specification

The `VkPhysicalDeviceGpaFeaturesAMD` structure is defined as:

    // Provided by VK_AMD_gpa_interface
    typedef struct VkPhysicalDeviceGpaFeaturesAMD {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           perfCounters;
        VkBool32           streamingPerfCounters;
        VkBool32           sqThreadTracing;
        VkBool32           clockModes;
    } VkPhysicalDeviceGpaFeaturesAMD;

## Members

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

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

- `perfCounters` specifies whether performance counters are supported.

- `streamingPerfCounters` specifies whether streaming performance counters are supported.

- `sqThreadTracing` specifies whether thread tracing is supported.

- `clockModes` specifies whether setting clock modes is supported.

## Description

If the `VkPhysicalDeviceGpaFeaturesAMD` 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 `VkPhysicalDeviceGpaFeaturesAMD`, 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.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceGpaFeaturesAMD-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_GPA_FEATURES_AMD

Structure Chaining
