* Bump API patch number and header version number to 29 for this update.
Github Issues:
* Remove redundant constraint on
slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue
224).
* Fix typo and remove link in Note in the
<<extended-functionality-instance-extensions-and-devices, Instance
Extensions and Device Extensions>> section (public issue 359).
* Fix erroneous validation statement for the pname:layout member of
slink:VkComputePipelineCreateInfo (public issue 362).
Internal Issues:
* Restore long figure captions using asciidoc sidebar blocks, due to
restrictions of asciidoc syntax (internal issue 101).
* Replace most latexmath equations with comparable markup in straight
asciidoc, which significantly improves time required to fully load and
process the HTML forms of the Specification. There are known minor font
and alignment inconsistencies with MathJax and PDF rendering of
latexmath equations. Please do not file github issues about these. We
are aware of the inconsistencies and will make refinements over time,
while the performance improvements are compelling in at least some major
browsers (internal issue 313).
* Move handcoded validity statements from +vk.xml+ into the Specification
body, easing work in the single-branch model. Specify the distinction
between these explicit statements, and the implicit validity statements
inferred from vk.xml. Validity statements now appear in two blocks for
each command and structure - handcoded "Valid Usage" and the implicit
"Valid Usage (Implicit)" (internal issue 392).
* Add the +returnedonly="false"+ attribute to WSI output structures,
removing incorrectly generated implicit validity statements for
slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR,
slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR,
slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures
(internal issue 486).
* Update slink:VkImageLayout to require the
ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images
(internal issue 487).
* Use an explicit format specifier string for the date command invocation
in the +Makefile+ instead of the shorthand -R option, which doesn't work
on BSD and MaxOS X date commands (internal issue 500).
Other Issues:
* Use the terms ``allocation scope'' and ``extension scope'' instead of
just ``scope'', and add them to the glossary.

= 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.
|
|

[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 [eq]#[-pname:size + 1, 2 {times}

pname:size - 1]# which would allow all possible non-empty-set intersections
|
|
of the output target and the viewport.

|
|
range using the smallest possible number of bits ends up with the specified

=== 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.

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.
|
|
|
|

The pname:maxPerStageResources must: be at least the smallest of the
|
|
following:
|
|
|
|
* the sum of the pname:maxPerStageDescriptorUniformBuffers,
|
|
pname:maxPerStageDescriptorStorageBuffers,
|
|
pname:maxPerStageDescriptorSampledImages,

It may: not be possible to reach this limit in every stage.

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 [eq]#[-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].
|
|
|
|
8:: The ptext:maxDescriptorSet* limit is _n_ times the corresponding
|
|
ptext:maxPerStageDescriptor* limit, where _n_ is the number of shader
|
|
stages supported by the VkPhysicalDevice.
|
|
If all shader stages are supported, _n_ = 6 (vertex, tessellation
|
|
control, tessellation evaluation, geometry, fragment, compute).

For the purposes of address alignment when accessing buffer memory
|
|
containing vertex attribute or texel data, the following formats are
|
|
considered _packed_ - whole texels or attributes are stored in a single data
|
|
element, rather than individual components occupying a single data element:

==== 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

==== 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>>.
|
|
|
|
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.

|
==== 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.

include::../api/protos/vkGetPhysicalDeviceFormatProperties.txt[]
|
|
|
|
* pname:physicalDevice is the physical device from which to query the
|
|
format properties.

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
|

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.

are supported by buffers or buffer views created with the queried
|
|
flink:vkGetPhysicalDeviceFormatProperties::pname:format:
|
|
|

Atomic operations are supported on
|
|
ename:VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER with this format.
|
|
|
|
ename:VK_FORMAT_FEATURE_VERTEX_BUFFER_BIT::

[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.

=== 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.

== 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.

|
|
|
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
|
|
* 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.
