[[features]]
= Features, Limits, and Formats
Vulkan is designed to support a wide range of hardware and as such there are
a number of features, limits, and formats which are not supported on all
hardware.
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).
It is expected that when new features or limits are added in a future Vulkan
version, new structure(s) and entry point(s) will be added as necessary to
query these.
New functionality added by <<extended-functionality-extensions,extensions>>
is not expected to modify the core feature and limit structures.
====
[[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.
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` 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.
====
// 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).
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.
+
--
[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 address of
the attribute plus the size of the attribute is greater than the size
of the bound buffer.
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.

=== Limit Requirements
The following table specifies the required: minimum/maximum for all Vulkan
graphics implementations.
Where a limit corresponds to a fine-grained device feature which is
optional:, the feature name is listed with two required: limits, one when
the feature is supported and one when it is not supported.
If an implementation supports a feature, the limits reported are the same
whether or not the feature is enabled.

implementations must: support.
For bitmasks a minimum limit is the least bits all implementations must:
set, but they may: have additional bits set beyond this minimum.

The ULP is determined by pname:subPixelInterpolationOffsetBits.
If pname:subPixelInterpolationOffsetBits is 4, this provides increments
of (1/2^4^) = 0.0625, and thus the range of supported interpolation
offsets would be [eq]#[-0.5, 0.4375]#.

==== Identification of Formats
A ``format'' is represented by a single enum value.
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.

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.

==== 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
<<features-formats-depth-stencil,below>>.
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 <<features-formats-non-packed,Byte mappings for non-packed/compressed
color formats>>.
The in-memory ordering of bytes within a component is determined by the host
endianness.

|====
Packed formats store multiple components within one underlying type.
The bit representation is that the first component specified in the name of
the format is in the most-significant bits and the last component specified
is in the least-significant bits of the underlying type.
The in-memory ordering of bytes comprising the underlying type is determined
by the host endianness.

[[features-formats-depth-stencil]]
==== Depth/Stencil Formats
Depth/stencil formats are considered opaque and need not be stored in the
exact number of bits per texel or component ordering indicated by the format
enum.
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 <<features-formats-compatibility,following>> table, all the formats
in the same row are compatible.

=== Format Properties
// refBegin vkGetPhysicalDeviceFormatProperties Lists physical device's format capabilities
To query supported format features which are properties of the physical
device, call:
include::../api/protos/vkGetPhysicalDeviceFormatProperties.txt[]
* pname:physicalDevice is the physical device from which to query the
format properties.
* pname:format is the format whose properties are queried.
* pname:pFormatProperties is a pointer to a slink:VkFormatProperties
structure in which physical device properties for pname:format are
returned.
include::../validity/protos/vkGetPhysicalDeviceFormatProperties.txt[]
// refBegin VkFormatProperties Structure specifying image format properties
The sname:VkPhysicalDeviceLimits structure is defined as:
include::../api/structs/VkFormatProperties.txt[]
* pname:linearTilingFeatures describes the features supported by
ename:VK_IMAGE_TILING_LINEAR.
* pname:optimalTilingFeatures describes the features supported by
ename:VK_IMAGE_TILING_OPTIMAL.
* pname:bufferFeatures describes the features supported by buffers.
Supported features are described as a set of elink:VkFormatFeatureFlagBits:
// refBegin VkFormatFeatureFlagBits Bitmask specifying features supported by a buffer
include::../api/enums/VkFormatFeatureFlagBits.txt[]
The pname:linearTilingFeatures and pname:optimalTilingFeatures members of
the sname:VkFormatProperties structure describe what features are supported
by ename:VK_IMAGE_TILING_LINEAR and ename:VK_IMAGE_TILING_OPTIMAL images,
respectively.
The following bits may: be set in pname:linearTilingFeatures and
pname:optimalTilingFeatures, indicating they are supported by images or
image views created with the queried
flink:vkGetPhysicalDeviceFormatProperties::pname:format:
ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT::
sname:VkImageView can: be sampled from.
See <<descriptorsets-sampledimage, sampled images>> section.
ename:VK_FORMAT_FEATURE_STORAGE_IMAGE_BIT::
sname:VkImageView can: be used as storage image.
See <<descriptorsets-storageimage, storage images>> section.
ename:VK_FORMAT_FEATURE_STORAGE_IMAGE_ATOMIC_BIT::
sname:VkImageView can: be used as storage image that supports atomic
operations.
ename:VK_FORMAT_FEATURE_COLOR_ATTACHMENT_BIT::
sname:VkImageView can: be used as a framebuffer color attachment and as
an input attachment.
ename:VK_FORMAT_FEATURE_COLOR_ATTACHMENT_BLEND_BIT::
sname:VkImageView can: be used as a framebuffer color attachment that
supports blending and as an input attachment.
ename:VK_FORMAT_FEATURE_DEPTH_STENCIL_ATTACHMENT_BIT::
sname:VkImageView can: be used as a framebuffer depth/stencil attachment
and as an input attachment.
ename:VK_FORMAT_FEATURE_BLIT_SRC_BIT::
sname:VkImage can: be used as pname:srcImage for the
fname:vkCmdBlitImage command.
ename:VK_FORMAT_FEATURE_BLIT_DST_BIT::
sname:VkImage can: be used as pname:dstImage for the
fname:vkCmdBlitImage command.
ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT::
If ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT is also set,
sname:VkImageView can: be used with a sampler that has either of
pname:magFilter or pname:minFilter set to ename:VK_FILTER_LINEAR, or
pname:mipmapMode set to ename:VK_SAMPLER_MIPMAP_MODE_LINEAR.
If ename:VK_FORMAT_FEATURE_BLIT_SRC_BIT is also set, sname:VkImage can
be used as the pname:srcImage to flink:vkCmdBlitImage with a
pname:filter of ename:VK_FILTER_LINEAR.
This bit must: only be exposed for formats that also support the
ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT or
ename:VK_FORMAT_FEATURE_BLIT_SRC_BIT.
+
If the format being queried is a depth/stencil format, this bit only
indicates that the depth aspect (not the stencil aspect) of an image of
this format supports linear filtering, and that linear filtering of the
depth aspect is supported whether depth compare is enabled in the
sampler or not.
If this bit is not present, linear filtering with depth compare disabled
is unsupported and linear filtering with depth compare enabled is
supported, but may: compute the filtered value in an
implementation-dependent manner which differs from the normal rules of
linear filtering.
The resulting value must: be in the range [eq]#[0,1]# and should: be
proportional to, or a weighted average of, the number of comparison
passes or failures.
ifdef::VK_IMG_filter_cubic[]
include::VK_IMG_filter_cubic/filter_cubic_sampled_bit_description.txt[]
endif::VK_IMG_filter_cubic[]
The following features may: appear in pname:bufferFeatures, indicating they
are supported by buffers or buffer views created with the queried
flink:vkGetPhysicalDeviceFormatProperties::pname:format:
ename:VK_FORMAT_FEATURE_UNIFORM_TEXEL_BUFFER_BIT::
Format can: be used to create a sname:VkBufferView that can: be bound to
a ename:VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER descriptor.
ename:VK_FORMAT_FEATURE_STORAGE_TEXEL_BUFFER_BIT::
Format can: be used to create a sname:VkBufferView that can: be bound to
a ename:VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER descriptor.
ename:VK_FORMAT_FEATURE_STORAGE_TEXEL_BUFFER_ATOMIC_BIT::
Atomic operations are supported on
ename:VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER with this format.
ename:VK_FORMAT_FEATURE_VERTEX_BUFFER_BIT::
Format can: be used as a vertex attribute format
(sname:VkVertexInputAttributeDescription::pname:format).
[NOTE]
.Note
====
If no format feature flags are supported, then the only possible use would
be image transfers - which alone are not useful.
As such, if no format feature flags are supported, the format itself is not
supported, and images of that format cannot be created.
====
If pname:format is a block-compression format, then buffers must: not
support any features for the format.
include::../validity/structs/VkFormatProperties.txt[]
[[features-required-format-support]]
=== Required Format Support
Implementations must: support at least the following set of features on the
listed formats.
For images, these features must: be supported for every elink:VkImageType
(including arrayed and cube variants) unless otherwise noted.
These features are supported on existing formats without needing to
advertise an extension or needing to explicitly enable them.
Support for additional functionality beyond the requirements listed here is
queried using the flink:vkGetPhysicalDeviceFormatProperties command.
The following tables show which feature bits must: be supported for each
format.

== Additional Image Capabilities
In addition to the minimum capabilities described in the previous sections
(<<features-limits,Limits>> and <<features-formats,Formats>>),
implementations may: support additional capabilities for certain types of
images.
For example, larger dimensions or additional sample counts for certain image
types, or additional capabilities for _linear_ tiling format images.
// refBegin vkGetPhysicalDeviceImageFormatProperties Lists physical device's image format capabilities
To query additional capabilities specific to image types, call:
include::../api/protos/vkGetPhysicalDeviceImageFormatProperties.txt[]
* pname:physicalDevice is the physical device from which to query the
image capabilities.
* pname:format is the image format, corresponding to
slink:VkImageCreateInfo::pname:format.
* pname:type is the image type, corresponding to
slink:VkImageCreateInfo::pname:imageType.
* pname:tiling is the image tiling, corresponding to
slink:VkImageCreateInfo::pname:tiling.
* pname:usage is the intended usage of the image, corresponding to
slink:VkImageCreateInfo::pname:usage.
* pname:flags is a bitmask describing additional parameters of the image,
corresponding to slink:VkImageCreateInfo::pname:flags.
* pname:pImageFormatProperties points to an instance of the
slink:VkImageFormatProperties structure in which capabilities are
returned.
The pname:format, pname:type, pname:tiling, pname:usage, and pname:flags
parameters correspond to parameters that would be consumed by
flink:vkCreateImage.
If pname:format is not a supported image format, or if the combination of
pname:format, pname:type, pname:tiling, pname:usage, and pname:flags is not
supported for images, then fname:vkGetPhysicalDeviceImageFormatProperties
returns ename:VK_ERROR_FORMAT_NOT_SUPPORTED.
The limitations on an image format that are reported by
fname:vkGetPhysicalDeviceImageFormatProperties have the following property:
if code:usage1 and code:usage2 of type elink:VkImageUsageFlags are such that
the bits set in code:usage1 are a subset of the bits set in code:usage2, and
code:flags1 and code:flags2 of type elink:VkImageCreateFlags are such that
the bits set in code:flags1 are a subset of the bits set in code:flags2,
then the limitations for code:usage1 and code:flags1 must: be no more strict
than the limitations for code:usage2 and code:flags2, for all values of
pname:format, pname:type, and pname:tiling.

// refBegin VkImageFormatProperties Structure specifying a image format properties
The sname:VkImageFormatProperties structure is defined as:
include::../api/structs/VkImageFormatProperties.txt[]
* pname:maxExtent are the maximum image dimensions.
See the <<features-extentperimagetype,Allowed Extent Values>> section
below for how these values are constrained by pname:type.
* pname:maxMipLevels is the maximum number of mipmap levels.
pname:maxMipLevels must: either be equal to 1 (valid only if
pname:tiling is ename:VK_IMAGE_TILING_LINEAR) or be equal to
[eq]#{lceil}log~2~(max(pname:width, pname:height, pname:depth)){rceil}
{plus} 1#.
[eq]#pname:width#, [eq]#pname:height#, and [eq]#pname:depth# are taken
from the corresponding members of pname:maxExtent.
* pname:maxArrayLayers is the maximum number of array layers.
pname:maxArrayLayers must: either be equal to 1 or be greater than or
equal to the pname:maxImageArrayLayers member of
slink:VkPhysicalDeviceLimits.
A value of 1 is valid only if pname:tiling is
ename:VK_IMAGE_TILING_LINEAR or if pname:type is ename:VK_IMAGE_TYPE_3D.
* pname:sampleCounts is a bitmask of elink:VkSampleCountFlagBits
specifying all the supported sample counts for this image as described
<<features-supported-sample-counts, below>>.
* pname:maxResourceSize is an upper bound on the total image size in
bytes, inclusive of all image subresources.
Implementations may: have an address space limit on total size of a
resource, which is advertised by this property.
pname:maxResourceSize must: be at least 2^31^.
[NOTE]
.Note
====
There is no mechanism to query the size of an image before creating it, to
compare that size against pname:maxResourceSize.
If an application attempts to create an image that exceeds this limit, the
creation will fail or the image will be invalid.
While the advertised limit must: be at least 2^31^, it may: not be possible
to create an image that approaches that size, particularly for
ename:VK_IMAGE_TYPE_1D.
====
If the combination of parameters to
fname:vkGetPhysicalDeviceImageFormatProperties is not supported by the
implementation for use in flink:vkCreateImage, then all members of
sname:VkImageFormatProperties will be filled with zero.

=== Supported Sample Counts
fname:vkGetPhysicalDeviceImageFormatProperties returns a bitmask of
elink:VkSampleCountFlagBits in pname:sampleCounts specifying the supported
sample counts for the image parameters.
pname:sampleCounts will be set to ename:VK_SAMPLE_COUNT_1_BIT if at least
one of the following conditions is true:
* pname:tiling is ename:VK_IMAGE_TILING_LINEAR
* pname:type is not ename:VK_IMAGE_TYPE_2D
* pname:flags contains ename:VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT
* Neither the ename:VK_FORMAT_FEATURE_COLOR_ATTACHMENT_BIT flag nor the
ename:VK_FORMAT_FEATURE_DEPTH_STENCIL_ATTACHMENT_BIT flag in
sname:VkFormatProperties::pname:optimalTilingFeatures returned by
flink:vkGetPhysicalDeviceFormatProperties is set
Otherwise, the bits set in pname:sampleCounts will be the sample counts
supported for the specified values of pname:usage and pname:format.
For each bit set in pname:usage, the supported sample counts relate to the
limits in sname:VkPhysicalDeviceLimits as follows:
* If pname:usage includes ename:VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT, a
superset of
sname:VkPhysicalDeviceLimits::pname:framebufferColorSampleCounts
* If pname:usage includes
ename:VK_IMAGE_USAGE_DEPTH_STENCIL_ATTACHMENT_BIT, and pname:format
includes a depth aspect, a superset of
sname:VkPhysicalDeviceLimits::pname:framebufferDepthSampleCounts
* If pname:usage includes
ename:VK_IMAGE_USAGE_DEPTH_STENCIL_ATTACHMENT_BIT, and pname:format
includes a stencil aspect, a superset of
sname:VkPhysicalDeviceLimits::pname:framebufferStencilSampleCounts
* If pname:usage includes ename:VK_IMAGE_USAGE_SAMPLED_BIT, and
pname:format includes a color aspect, a superset of
sname:VkPhysicalDeviceLimits::pname:sampledImageColorSampleCounts
* If pname:usage includes ename:VK_IMAGE_USAGE_SAMPLED_BIT, and
pname:format includes a depth aspect, a superset of
sname:VkPhysicalDeviceLimits::pname:sampledImageDepthSampleCounts
* If pname:usage includes ename:VK_IMAGE_USAGE_SAMPLED_BIT, and
pname:format is an integer format, a superset of
sname:VkPhysicalDeviceLimits::pname:sampledImageIntegerSampleCounts
* If pname:usage includes ename:VK_IMAGE_USAGE_STORAGE_BIT, a superset of
sname:VkPhysicalDeviceLimits::pname:storageImageSampleCounts
If multiple bits are set in pname:usage, pname:sampleCounts will be the
intersection of the per-usage values described above.
If none of the bits described above are set in pname:usage, then there
is no corresponding limit in sname:VkPhysicalDeviceLimits. In this case,
pname:sampleCounts must: include at least ename:VK_SAMPLE_COUNT_1_BIT.
