[[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 behaviour 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. To disable all features which are not
required:, set pname:pEnabledFeatures to `NULL`.

[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 mustnot: 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 (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 mustnot: modify any other memory.
  ** Out-of-bounds atomics may: modify values within the memory range(s) bound
     to the buffer, but mustnot: 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 (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 behaviour up
     to and including application termination.

.Note
====

    See <<vertexpostproc-viewport,Controlling the Viewport>>.
+
--
[NOTE]
.Note
====
The intent of the pname:viewportBoundsRange limit is to allow a maximum sized
viewport to be arbitrarily shifted relative to the output target as long
as at least some portion intersects. This would give a bounds limit of
latexmath:[$[- \mathit{maxViewportDimensions}+1,
             2 \times \mathit{maxViewportDimensions} -1\]$] which would allow
all possible non-empty-set intersections of the output target and the viewport.
Since these numbers are typically powers of two, picking the signed number
range using the smalled possible number of bits, ends up with the specified
range.

=== 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.

1::
    The *Limit Type* column indicates the limit is either the minimum limit all
    implementations must: support or the maximum limit all 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.

2::
    The pname:maxPerStageResources must: be at least the smallest of the
    following:
+
--
* the sum of the pname:maxPerStageDescriptorUniformBuffers,
  pname:maxPerStageDescriptorStorageBuffers,
  pname:maxPerStageDescriptorSampledImages,
  pname:maxPerStageDescriptorStorageImages,
  pname:maxPerStageDescriptorInputAttachments, pname:maxColorAttachments
  limits, or
* 128.
--
+
It may: not be possible to reach this limit in every stage.

3::
    See <<features-limits-maxViewportDimensions,pname:maxViewportDimensions>>
    for the required relationship to other limits.

4::
    See <<features-limits-viewportboundsrange,pname:viewportBoundsRange>>
    for the required relationship to other limits.

5::
    The values pname:minInterpolationOffset and pname:maxInterpolationOffset
    describe the closed interval of supported interpolation offsets:
    [pname:minInterpolationOffset, pname:maxInterpolationOffset]. 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 [-0.5, 0.4375].

6::
    The point size ULP is determined by pname:pointSizeGranularity. If the
    pname:pointSizeGranularity is 0.125, the range of supported point sizes
    must: be at least [1.0, 63.875].

7::
    The line width ULP is determined by pname:lineWidthGranularity. If the
    pname:lineWidthGranularity is 0.0625, the range of supported line widths
    must: be at least [1.0, 7.9375].

==== 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:

    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.

|===================
| Numeric format | Description
| etext:UNORM    | The components are unsigned normalized values in the range [0,1]
| etext:SNORM    | The components are signed normalized values in the range [-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.

==== 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
mustnot: occur for color formats. Depth/stencil formats have more relaxed
requirements as discussed <<features-formats-depth-stencil,below>>.

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 mustnot: substitute
a different depth or stencil precision than that described in the format
(e.g. D16 mustnot: 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 latexmath:[$[0,1\]$] and should: be proportional to, or a weighted
    average of, the number of comparison passes or failures.

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 mustnot: 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.

14+|The ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT,
ename:VK_FORMAT_FEATURE_BLIT_SRC_BIT and
ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT features must: be

|=========================================


== 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.

include::../validity/protos/vkGetPhysicalDeviceImageFormatProperties.txt[]

// 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
        latexmath:[$\left\lceil\log_2(\max(
                    \mathit{width},\mathit{height},\mathit{depth}))
                    \right\rceil + 1$]
    where latexmath:[$\mathit{width}$], latexmath:[$\mathit{height}$], and
    latexmath:[$\mathit{depth}$] 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.

include::../validity/structs/VkImageFormatProperties.txt[]


[[features-supported-sample-counts]]
=== 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
 * The ename:VK_FORMAT_FEATURE_COLOR_ATTACHMENT_BIT flag in
   sname:VkFormatProperties::pname:optimalTilingFeatures returned by
   flink:vkGetPhysicalDeviceFormatProperties is not 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.
