VkPhysicalDeviceFormatPackFeaturesARM

The VkPhysicalDeviceFormatPackFeaturesARM structure is defined as:

typedef struct VkPhysicalDeviceFormatPackFeaturesARM {
    VkStructureType sType;
    void* pNext;
    VkBool32 formatPack;
} VkPhysicalDeviceFormatPackFeaturesARM;

pub struct PhysicalDeviceFormatPackFeaturesARM {
    s_type: vk::StructureType,
    p_next: *mut c_void,
    format_pack: vk::Bool32,
}

This structure describes the following feature:

• FEATURES FORMATPACK
  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

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.
