# VkPhysicalDeviceFormatPackFeaturesARM(3) Manual Page

## Name

VkPhysicalDeviceFormatPackFeaturesARM - Structure describing whether the additional formats feature is supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceFormatPackFeaturesARM` structure is defined as:

    // Provided by VK_ARM_format_pack
    typedef struct VkPhysicalDeviceFormatPackFeaturesARM {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           formatPack;
    } VkPhysicalDeviceFormatPackFeaturesARM;

## Members

This structure describes the following feature:

- `formatPack` indicates that the implementation must support using a VkFormat of `VK_FORMAT_R10X6_UINT_PACK16_ARM`, `VK_FORMAT_R10X6G10X6_UINT_2PACK16_ARM`, `VK_FORMAT_R10X6G10X6B10X6A10X6_UINT_4PACK16_ARM`, `VK_FORMAT_R12X4_UINT_PACK16_ARM`, `VK_FORMAT_R12X4G12X4_UINT_2PACK16_ARM`, `VK_FORMAT_R12X4G12X4B12X4A12X4_UINT_4PACK16_ARM`, `VK_FORMAT_R14X2_UINT_PACK16_ARM`, `VK_FORMAT_R14X2G14X2_UINT_2PACK16_ARM`, and `VK_FORMAT_R14X2G14X2B14X2A14X2_UINT_4PACK16_ARM`, with at least the following VkFormatFeatureFlagBits:

  - `VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT`

  - `VK_FORMAT_FEATURE_TRANSFER_SRC_BIT`

  - `VK_FORMAT_FEATURE_TRANSFER_DST_BIT`

## Description

If the `VkPhysicalDeviceFormatPackFeaturesARM` 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 `VkPhysicalDeviceFormatPackFeaturesARM`, 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-VkPhysicalDeviceFormatPackFeaturesARM-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_FORMAT_PACK_FEATURES_ARM`
