Features describe functionality which is optional: and which must: be explicitly enabled before use. Limits describe implementation-dependent minimums, maximums, and other device characteristics that an application may: need to be aware of. Supported buffer and image formats may: vary across implementations. A minimum set of format features are guaranteed, but others must: be explicitly queried before use to ensure they are supported by the implementation. [NOTE] .Note ==== The features and limits are reported via basic structures (that is slink:VkPhysicalDeviceFeatures and slink:VkPhysicalDeviceLimits), as well as extensible structures (sname:VkPhysicalDeviceFeatures2 and sname:VkPhysicalDeviceProperties2) which were added in `<>` and included in Vulkan 1.1. When new features or limits are added in future Vulkan version or extensions, each extension should: introduce one new feature structure and/or limit structure (as needed). These structures can: be added to the pname:pNext chain of the sname:VkPhysicalDeviceFeatures2 and sname:VkPhysicalDeviceProperties2 structures, respectively. ==== [[features-features]] == Features The Specification defines a set of optional: features that may: be supported by a Vulkan implementation. Support for features is reported and enabled on a per-feature basis. Features are properties of the physical device. [open,refpage='vkGetPhysicalDeviceFeatures',desc='Reports capabilities of a physical device',type='protos'] -- To query supported features, call: include::../api/protos/vkGetPhysicalDeviceFeatures.txt[] * pname:physicalDevice is the physical device from which to query the supported features. * pname:pFeatures is a pointer to a slink:VkPhysicalDeviceFeatures structure in which the physical device features are returned. For each feature, a value of ename:VK_TRUE specifies that the feature is supported on this physical device, and ename:VK_FALSE specifies that the feature is not supported. include::../validity/protos/vkGetPhysicalDeviceFeatures.txt[] -- Fine-grained features used by a logical device must: be enabled at sname:VkDevice creation time. If a feature is enabled that the physical device does not support, sname:VkDevice creation will fail. If an application uses a feature without enabling it at sname:VkDevice creation time, the device behavior is undefined. The validation layer will warn if features are used without being enabled. The fine-grained features are enabled by passing a pointer to the sname:VkPhysicalDeviceFeatures structure via the pname:pEnabledFeatures member of the sname:VkDeviceCreateInfo structure that is passed into the fname:vkCreateDevice call. If a member of pname:pEnabledFeatures is set to ename:VK_TRUE or ename:VK_FALSE, then the device will be created with the indicated feature enabled or disabled, respectively. ifdef::VK_VERSION_1_1,VK_KHR_get_physical_device_properties2[] Features can: also be enabled by using the slink:VkPhysicalDeviceFeatures2 structure. endif::VK_VERSION_1_1,VK_KHR_get_physical_device_properties2[] If an application wishes to enable all features supported by a device, it can: simply pass in the sname:VkPhysicalDeviceFeatures structure that was previously returned by fname:vkGetPhysicalDeviceFeatures. To disable an individual feature, the application can: set the desired member to ename:VK_FALSE in the same structure. Setting pname:pEnabledFeatures to `NULL` ifdef::VK_VERSION_1_1,VK_KHR_get_physical_device_properties2[] and not including a slink:VkPhysicalDeviceFeatures2 in the pname:pNext member of slink:VkDeviceCreateInfo endif::VK_VERSION_1_1,VK_KHR_get_physical_device_properties2[] is equivalent to setting all members of the structure to ename:VK_FALSE. [NOTE] .Note ==== Some features, such as pname:robustBufferAccess, may: incur a run-time performance cost. Application writers should: carefully consider the implications of enabling all supported features. ==== ifdef::VK_VERSION_1_1,VK_KHR_get_physical_device_properties2[] [open,refpage='vkGetPhysicalDeviceFeatures2',desc='Reports capabilities of a physical device',type='protos'] -- To query supported features defined by the core or extensions, call: ifdef::VK_VERSION_1_1[] include::../api/protos/vkGetPhysicalDeviceFeatures2.txt[] endif::VK_VERSION_1_1[] ifdef::VK_VERSION_1_1+VK_KHR_get_physical_device_properties2[or the equivalent command] ifdef::VK_KHR_get_physical_device_properties2[] include::../api/protos/vkGetPhysicalDeviceFeatures2KHR.txt[] endif::VK_KHR_get_physical_device_properties2[] * pname:physicalDevice is the physical device from which to query the supported features. * pname:pFeatures is a pointer to a slink:VkPhysicalDeviceFeatures2 structure in which the physical device features are returned. Each structure in pname:pFeatures and its pname:pNext chain contain members corresponding to fine-grained features. fname:vkGetPhysicalDeviceFeatures2 writes each member to a boolean value indicating whether that feature is supported. include::../validity/protos/vkGetPhysicalDeviceFeatures2.txt[] -- [open,refpage='VkPhysicalDeviceFeatures2',desc='Structure describing the fine-grained features that can be supported by an implementation',type='structs'] -- The sname:VkPhysicalDeviceFeatures2 structure is defined as: include::../api/structs/VkPhysicalDeviceFeatures2.txt[] ifdef::VK_KHR_get_physical_device_properties2[] or the equivalent include::../api/structs/VkPhysicalDeviceFeatures2KHR.txt[] endif::VK_KHR_get_physical_device_properties2[] The sname:VkPhysicalDeviceFeatures2 structure is defined as: * pname:sType is the type of this structure. * pname:pNext is `NULL` or a pointer to an extension-specific structure. * pname:features is a structure of type slink:VkPhysicalDeviceFeatures describing the fine-grained features of the Vulkan 1.0 API. The pname:pNext chain of this structure is used to extend the structure with features defined by extensions. This structure can: be used in flink:vkGetPhysicalDeviceFeatures2 or can: be in the pname:pNext chain of a slink:VkDeviceCreateInfo structure, in which case it controls which features are enabled in the device in lieu of pname:pEnabledFeatures. include::../validity/structs/VkPhysicalDeviceFeatures2.txt[] -- endif::VK_VERSION_1_1,VK_KHR_get_physical_device_properties2[] [open,refpage='VkPhysicalDeviceFeatures',desc='Structure describing the fine-grained features that can be supported by an implementation',type='structs'] -- The sname:VkPhysicalDeviceFeatures structure is defined as: include::../api/structs/VkPhysicalDeviceFeatures.txt[] The members of the sname:VkPhysicalDeviceFeatures structure describe the following features: * [[features-features-robustBufferAccess]] pname:robustBufferAccess specifies that accesses to buffers are bounds-checked against the range of the buffer descriptor (as determined by sname:VkDescriptorBufferInfo::pname:range, sname:VkBufferViewCreateInfo::pname:range, or the size of the buffer). Out of bounds accesses must: not cause application termination, and the effects of shader loads, stores, and atomics must: conform to an implementation-dependent behavior as described below. ** A buffer access is considered to be out of bounds if any of the following are true: *** The pointer was formed by code:OpImageTexelPointer and the coordinate is less than zero or greater than or equal to the number of whole elements in the bound range. *** The pointer was not formed by code:OpImageTexelPointer and the object pointed to is not wholly contained within the bound range. ifdef::VK_VERSION_1_1,VK_KHR_variable_pointers[] This includes accesses performed via _variable pointers_ where the buffer descriptor being accessed cannot be statically determined. Uninitialized pointers and pointers equal to code:OpConstantNull are treated as pointing to a zero-sized object, so all accesses through such pointers are considered to be out of bounds. endif::VK_VERSION_1_1,VK_KHR_variable_pointers[] + [NOTE] .Note ==== If a SPIR-V code:OpLoad instruction loads a structure and the tail end of the structure is out of bounds, then all members of the structure are considered out of bounds even if the members at the end are not statically used. ==== *** If any buffer access in a given SPIR-V block is determined to be out of bounds, then any other access of the same type (load, store, or atomic) in the same SPIR-V block that accesses an address less than 16 bytes away from the out of bounds address may: also be considered out of bounds. ** Out-of-bounds buffer loads will return any of the following values: *** Values from anywhere within the memory range(s) bound to the buffer (possibly including bytes of memory past the end of the buffer, up to the end of the bound range). *** Zero values, or [eq]#(0,0,0,x)# vectors for vector reads where x is a valid value represented in the type of the vector components and may: be any of: **** 0, 1, or the maximum representable positive integer value, for signed or unsigned integer components **** 0.0 or 1.0, for floating-point components ** Out-of-bounds writes may: modify values within the memory range(s) bound to the buffer, but must: not modify any other memory. ** Out-of-bounds atomics may: modify values within the memory range(s) bound to the buffer, but must: not modify any other memory, and return an undefined value. ** Vertex input attributes are considered out of bounds if the offset of the attribute in the bound vertex buffer range plus the size of the attribute is greater than either: + *** code:vertexBufferRangeSize, if [eq]#code:bindingStride == 0#; or *** [eq]#(code:vertexBufferRangeSize - (code:vertexBufferRangeSize % code:bindingStride))# + where code:vertexBufferRangeSize is the byte size of the memory range bound to the vertex buffer binding and code:bindingStride is the byte stride of the corresponding vertex input binding. Further, if any vertex input attribute using a specific vertex input binding is out of bounds, then all vertex input attributes using that vertex input binding for that vertex shader invocation are considered out of bounds. *** If a vertex input attribute is out of bounds, it will be assigned one of the following values: **** Values from anywhere within the memory range(s) bound to the buffer, converted according to the format of the attribute. **** Zero values, format converted according to the format of the attribute. **** Zero values, or [eq]#(0,0,0,x)# vectors, as described above. ** If pname:robustBufferAccess is not enabled, out of bounds accesses may: corrupt any memory within the process and cause undefined behavior up to and including application termination. * [[features-features-fullDrawIndexUint32]] pname:fullDrawIndexUint32 specifies the full 32-bit range of indices is supported for indexed draw calls when using a elink:VkIndexType of ename:VK_INDEX_TYPE_UINT32. pname:maxDrawIndexedIndexValue is the maximum index value that may: be used (aside from the primitive restart index, which is always 2^32^-1 when the elink:VkIndexType is ename:VK_INDEX_TYPE_UINT32).

The name of a format is usually built up by using the following pattern: VK_FORMAT_{component-format|compression-scheme}_{numeric-format} The component-format indicates either the size of the R, G, B, and A components (if they are present) in the case of a color format, or the size of the depth (D) and stencil (S) components (if they are present) in the case of a depth/stencil format (see below). An X indicates a component that is unused, but may: be present for padding. <<< [[features-formats-numericformat]] .Interpretation of Numeric Format [width="95%",cols="2,10",options="header"] |==== | Numeric format | Description | etext:UNORM | The components are unsigned normalized values in the range [eq]#[0,1]# | etext:SNORM | The components are signed normalized values in the range [eq]#[-1,1]# | etext:USCALED | The components are unsigned integer values that get converted to floating-point in the range [0,2^n^-1] | etext:SSCALED | The components are signed integer values that get converted to floating-point in the range [-2^n-1^,2^n-1^-1] | etext:UINT | The components are unsigned integer values in the range [0,2^n^-1] | etext:SINT | The components are signed integer values in the range [-2^n-1^,2^n-1^-1] | etext:UFLOAT | The components are unsigned floating-point numbers (used by packed, shared exponent, and some compressed formats) | etext:SFLOAT | The components are signed floating-point numbers | etext:SRGB | The R, G, and B components are unsigned normalized values that represent values using sRGB nonlinear encoding, while the A component (if one exists) is a regular unsigned normalized value |==== The suffix etext:_PACKnn indicates that the format is packed into an underlying type with nn bits. ifdef::VK_VERSION_1_1,VK_KHR_sampler_ycbcr_conversion[] The suffix etext:_mPACKnn is a short-hand that indicates that the format has several components (which may or may not be stored in separate _planes_) that are each packed into an underlying type with nn bits. endif::VK_VERSION_1_1,VK_KHR_sampler_ycbcr_conversion[] The suffix etext:_BLOCK indicates that the format is a block-compressed format, with the representation of multiple pixels encoded interdependently within a region.

See <>. |==== ifdef::VK_VERSION_1_1,VK_KHR_sampler_ycbcr_conversion[] For _multi-planar_ images, the components in separate _planes_ are separated by underscores, and the number of planes is indicated by the addition of a etext:_2PLANE or etext:_3PLANE suffix. Similarly, the separate aspects of depth-stencil formats are separated by underscores, although these are not considered separate planes. Formats are suffixed by etext:_422 to indicate that planes other than the first are reduced in size by a factor of two horizontally or that the R and B values appear at half the horizontal frequency of the G values, etext:_420 to indicate that planes other than the first are reduced in size by a factor of two both horizontally and vertically, and etext:_444 for consistency to indicate that all three planes of a three-planar image are the same size. [NOTE] .Note ==== No common format has a single plane containing both R and B channels but does not store these channels at reduced horizontal resolution. ==== endif::VK_VERSION_1_1,VK_KHR_sampler_ycbcr_conversion[] ==== Representation Color formats must: be represented in memory in exactly the form indicated by the format's name. This means that promoting one format to another with more bits per component and/or additional components must: not occur for color formats. Depth/stencil formats have more relaxed requirements as discussed <>. Each format has an _element size_, the number of bytes used to stored one element or one compressed block, with the value of the element size listed in slink:VkFormat. The representation of non-packed formats is that the first component specified in the name of the format is in the lowest memory addresses and the last component specified is in the highest memory addresses.

However, implementations must: not substitute a different depth or stencil precision than that described in the format (e.g. D16 must: not be implemented as D24 or D32). [[features-formats-compatibility-classes]] ==== Format Compatibility Classes Uncompressed color formats are _compatible_ with each other if they occupy the same number of bits per data element. Compressed color formats are compatible with each other if the only difference between them is the numerical type of the uncompressed pixels (e.g. signed vs. unsigned, or SRGB vs. UNORM encoding). Each depth/stencil format is only compatible with itself. In the <> table, all the formats in the same row are compatible.
