Features describe functionality that is not required: and which must: be explicitly enabled. 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 on extensibility ==== The features and limits are reported via basic structures (that is slink:VkPhysicalDeviceFeatures and slink:VkPhysicalDeviceLimits), as well as extensible structures (sname:VkPhysicalDeviceFeatures2KHR and sname:VkPhysicalDeviceProperties2KHR) which were added in code:VK_KHR_get_physical_device_properties2. 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:VkPhysicalDeviceFeatures2KHR and sname:VkPhysicalDeviceProperties2KHR structures, respectively. ==== [[features-features]] == Features The Specification defines a set of fine-grained features that are not required:, but 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. // refBegin vkGetPhysicalDeviceFeatures Reports capabilities of a physical device 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 indicates that the feature is supported on this physical device, and ename:VK_FALSE indicates 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_KHR_get_physical_device_properties2[] Features can: also be enabled by using the slink:VkPhysicalDeviceFeatures2KHR structure. endif::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_KHR_get_physical_device_properties2[] and not including a slink:VkPhysicalDeviceFeatures2KHR in the pname:pNext member of slink:VkDeviceCreateInfo endif::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_KHR_get_physical_device_properties2[] // refBegin vkGetPhysicalDeviceFeatures2KHR Reports capabilities of a physical device To query supported features defined by the core or extensions, call: include::../api/protos/vkGetPhysicalDeviceFeatures2KHR.txt[] * pname:physicalDevice is the physical device from which to query the supported features. * pname:pFeatures is a pointer to a slink:VkPhysicalDeviceFeatures2KHR 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:vkGetPhysicalDeviceFeatures2KHR writes each member to a boolean value indicating whether that feature is supported. include::../validity/protos/vkGetPhysicalDeviceFeatures2KHR.txt[] // refBegin VkPhysicalDeviceFeatures2KHR Structure describing the fine-grained features that can be supported by an implementation The sname:VkPhysicalDeviceFeatures2KHR structure is defined as: include::../api/structs/VkPhysicalDeviceFeatures2KHR.txt[] The sname:VkPhysicalDeviceFeatures2KHR 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.

This structure can: be used in flink:vkGetPhysicalDeviceFeatures2KHR 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/VkPhysicalDeviceFeatures2KHR.txt[] endif::VK_KHR_get_physical_device_properties2[] // refBegin VkPhysicalDeviceFeatures Structure describing the fine-grained features that can be supported by an implementation 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 indicates 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).

The name of a format is usually built up by using the following pattern: etext:VK_FORMAT_{component-format|compression-scheme}_{numeric-format} The component-format specifies 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. The suffix etext:_BLOCK indicates that the format is a block-compressed format, with the representation of multiple pixels encoded interdependently within a region. [[features-formats-compressionscheme]] .Interpretation of Compression Scheme [width="95%",cols="2,10",options="header"] |==== | Compression scheme | Description | etext:BC | Block Compression. See <>. | etext:ETC2 | Ericsson Texture Compression. See <>. | etext:EAC | ETC2 Alpha Compression. See <>. | etext:ASTC | Adaptive Scalable Texture Compression (LDR Profile). See <>. |==== ==== 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. See <>. The in-memory ordering of bytes within a component is determined by the host endianness.
