Description

The following bits may be set in linearTilingFeatures and optimalTilingFeatures, specifying that the features are supported by images or image views or sampler Y′CBCR conversion objects created with the queried vkGetPhysicalDeviceFormatProperties2::format:

  • VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_BIT specifies that an image view can be sampled from.

  • VK_FORMAT_FEATURE_2_STORAGE_IMAGE_BIT specifies that an image view can be used as a storage image.

  • VK_FORMAT_FEATURE_2_STORAGE_IMAGE_ATOMIC_BIT specifies that an image view can be used as storage image that supports atomic operations.

  • VK_FORMAT_FEATURE_2_COLOR_ATTACHMENT_BIT specifies that an image view can be used as a framebuffer color attachment and as an input attachment.

  • VK_FORMAT_FEATURE_2_COLOR_ATTACHMENT_BLEND_BIT specifies that an image view can be used as a framebuffer color attachment that supports blending.

  • VK_FORMAT_FEATURE_2_DEPTH_STENCIL_ATTACHMENT_BIT specifies that an image view can be used as a framebuffer depth/stencil attachment and as an input attachment.

  • VK_FORMAT_FEATURE_2_BLIT_SRC_BIT specifies that an image can be used as the srcImage for vkCmdBlitImage2 and vkCmdBlitImage.

  • VK_FORMAT_FEATURE_2_BLIT_DST_BIT specifies that an image can be used as the dstImage for vkCmdBlitImage2 and vkCmdBlitImage.

  • VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_FILTER_LINEAR_BIT specifies that if VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_BIT is also set, an image view can be used with a sampler that has either of magFilter or minFilter set to VK_FILTER_LINEAR, or mipmapMode set to VK_SAMPLER_MIPMAP_MODE_LINEAR. If VK_FORMAT_FEATURE_2_BLIT_SRC_BIT is also set, an image can be used as the srcImage for vkCmdBlitImage2 and vkCmdBlitImage with a filter of VK_FILTER_LINEAR. This bit must only be exposed for formats that also support the VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_BIT or VK_FORMAT_FEATURE_2_BLIT_SRC_BIT.

    If the format being queried is a depth/stencil format, this bit only specifies that the depth aspect (not the stencil aspect) of an image of this format supports linear filtering. Where depth comparison is supported it may be linear filtered whether this bit is present or not, but where this bit is not present the filtered value may be computed in an implementation-dependent manner which differs from the normal rules of linear filtering. The resulting value must be in the range [0,1] and should be proportional to, or a weighted average of, the number of comparison passes or failures.

  • VK_FORMAT_FEATURE_2_TRANSFER_SRC_BIT specifies that an image can be used as a source image for copy commands.

  • VK_FORMAT_FEATURE_2_TRANSFER_DST_BIT specifies that an image can be used as a destination image for copy commands and clear commands.

  • VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_FILTER_MINMAX_BIT specifies VkImage can be used as a sampled image with a min or max VkSamplerReductionMode. This bit must only be exposed for formats that also support the VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_BIT.

  • VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_FILTER_CUBIC_BIT specifies that VkImage can be used with a sampler that has either of magFilter or minFilter set to VK_FILTER_CUBIC_EXT, or be the source image for a blit with filter set to VK_FILTER_CUBIC_EXT. This bit must only be exposed for formats that also support the VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_BIT. If the format being queried is a depth/stencil format, this only specifies that the depth aspect is cubic filterable.

  • VK_FORMAT_FEATURE_2_MIDPOINT_CHROMA_SAMPLES_BIT specifies that an application can define a sampler Y′CBCR conversion using this format as a source, and that an image of this format can be used with a VkSamplerYcbcrConversionCreateInfo xChromaOffset and/or yChromaOffset of VK_CHROMA_LOCATION_MIDPOINT. Otherwise both xChromaOffset and yChromaOffset must be VK_CHROMA_LOCATION_COSITED_EVEN. If a format does not incorporate chroma downsampling (it is not a “422” or “420” format) but the implementation supports sampler Y′CBCR conversion for this format, the implementation must set VK_FORMAT_FEATURE_2_MIDPOINT_CHROMA_SAMPLES_BIT.

  • VK_FORMAT_FEATURE_2_COSITED_CHROMA_SAMPLES_BIT specifies that an application can define a sampler Y′CBCR conversion using this format as a source, and that an image of this format can be used with a VkSamplerYcbcrConversionCreateInfo xChromaOffset and/or yChromaOffset of VK_CHROMA_LOCATION_COSITED_EVEN. Otherwise both xChromaOffset and yChromaOffset must be VK_CHROMA_LOCATION_MIDPOINT. If neither VK_FORMAT_FEATURE_2_COSITED_CHROMA_SAMPLES_BIT nor VK_FORMAT_FEATURE_2_MIDPOINT_CHROMA_SAMPLES_BIT is set, the application must not define a sampler Y′CBCR conversion using this format as a source.

  • VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_YCBCR_CONVERSION_LINEAR_FILTER_BIT specifies that an application can define a sampler Y′CBCR conversion using this format as a source with chromaFilter set to VK_FILTER_LINEAR.

  • VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_YCBCR_CONVERSION_SEPARATE_RECONSTRUCTION_FILTER_BIT specifies that the format can have different chroma, min, and mag filters.

  • VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_YCBCR_CONVERSION_CHROMA_RECONSTRUCTION_EXPLICIT_BIT specifies that reconstruction is explicit, as described in https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#textures-chroma-reconstruction. If this bit is not present, reconstruction is implicit by default.

  • VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_YCBCR_CONVERSION_CHROMA_RECONSTRUCTION_EXPLICIT_FORCEABLE_BIT specifies that reconstruction can be forcibly made explicit by setting VkSamplerYcbcrConversionCreateInfo::forceExplicitReconstruction to VK_TRUE. If the format being queried supports VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_YCBCR_CONVERSION_CHROMA_RECONSTRUCTION_EXPLICIT_BIT it must also support VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_YCBCR_CONVERSION_CHROMA_RECONSTRUCTION_EXPLICIT_FORCEABLE_BIT.

  • VK_FORMAT_FEATURE_2_DISJOINT_BIT specifies that a multi-planar image can have the VK_IMAGE_CREATE_DISJOINT_BIT set during image creation. An implementation must not set VK_FORMAT_FEATURE_2_DISJOINT_BIT for single-plane formats.

  • VK_FORMAT_FEATURE_2_FRAGMENT_DENSITY_MAP_BIT_EXT specifies that an image view can be used as a fragment density map attachment.

  • VK_FORMAT_FEATURE_2_FRAGMENT_SHADING_RATE_ATTACHMENT_BIT_KHR specifies that an image view can be used as a fragment shading rate attachment. An implementation must not set this feature for formats with a numeric format other than UINT, or set it as a buffer feature.

  • VK_FORMAT_FEATURE_2_VIDEO_DECODE_OUTPUT_BIT_KHR specifies that an image view with this format can be used as a decode output picture in video decode operations.

  • VK_FORMAT_FEATURE_2_VIDEO_DECODE_DPB_BIT_KHR specifies that an image view with this format can be used as an output reconstructed picture or an input reference picture in video decode operations.

  • VK_FORMAT_FEATURE_2_VIDEO_ENCODE_INPUT_BIT_KHR specifies that an image view with this format can be used as an encode input picture in video encode operations.

  • VK_FORMAT_FEATURE_2_VIDEO_ENCODE_DPB_BIT_KHR specifies that an image view with this format can be used as an output reconstructed picture or an input reference picture in video encode operations.

    Note

    Specific video profiles may have additional restrictions on the format and other image creation parameters corresponding to image views used by video coding operations that can be enumerated using the vkGetPhysicalDeviceVideoFormatPropertiesKHR command.

  • VK_FORMAT_FEATURE_2_STORAGE_READ_WITHOUT_FORMAT_BIT specifies that image views or buffer views created with this format can be used as storage images or storage texel buffers respectively for read operations without specifying a format.

  • VK_FORMAT_FEATURE_2_STORAGE_WRITE_WITHOUT_FORMAT_BIT specifies that image views or buffer views created with this format can be used as storage images or storage texel buffers respectively for write operations without specifying a format.

  • VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_DEPTH_COMPARISON_BIT specifies that image views created with this format can be used for depth comparison performed by OpImage*Dref* instructions.

  • VK_FORMAT_FEATURE_2_LINEAR_COLOR_ATTACHMENT_BIT_NV specifies that the format is supported as a renderable Linear Color Attachment. This bit will be set for renderable color formats in the linearTilingFeatures. This must not be set in the optimalTilingFeatures or bufferFeatures members.

  • VK_FORMAT_FEATURE_2_WEIGHT_IMAGE_BIT_QCOM specifies that image views created with this format can be used as the weight image input to weight image sampling operations.

  • VK_FORMAT_FEATURE_2_WEIGHT_SAMPLED_IMAGE_BIT_QCOM specifies that image views created with this format can be sampled in weight image sampling operations.

  • VK_FORMAT_FEATURE_2_BLOCK_MATCHING_BIT_QCOM specifies that image views created with this format can be used in block matching operations.

  • VK_FORMAT_FEATURE_2_BOX_FILTER_SAMPLED_BIT_QCOM specifies that image views created with this format can be sampled in box filter sampling operations.

  • VK_FORMAT_FEATURE_2_HOST_IMAGE_TRANSFER_BIT_EXT specifies that an image can be created with VK_IMAGE_USAGE_HOST_TRANSFER_BIT_EXT.

The following bits may be set in bufferFeatures, specifying that the features are supported by buffers or buffer views created with the queried vkGetPhysicalDeviceFormatProperties2::format:

  • VK_FORMAT_FEATURE_2_UNIFORM_TEXEL_BUFFER_BIT specifies that the format can be used to create a buffer view that can be bound to a VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER descriptor.

  • VK_FORMAT_FEATURE_2_STORAGE_TEXEL_BUFFER_BIT specifies that the format can be used to create a buffer view that can be bound to a VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER descriptor.

  • VK_FORMAT_FEATURE_2_STORAGE_TEXEL_BUFFER_ATOMIC_BIT specifies that atomic operations are supported on VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER with this format.

  • VK_FORMAT_FEATURE_2_VERTEX_BUFFER_BIT specifies that the format can be used as a vertex attribute format (VkVertexInputAttributeDescription::format).

  • VK_FORMAT_FEATURE_2_ACCELERATION_STRUCTURE_VERTEX_BUFFER_BIT_KHR specifies that the format can be used as the vertex format when creating an acceleration structure (VkAccelerationStructureGeometryTrianglesDataKHR::vertexFormat). This format can also be used as the vertex format in host memory when doing host acceleration structure builds.

  • VK_FORMAT_FEATURE_2_STORAGE_READ_WITHOUT_FORMAT_BIT specifies that buffer views created with this format can be used as storage texel buffers for read operations without specifying a format.
