= 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), 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
|
|
|
|
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.

|
|
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.

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.
|
|
ifdef::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_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 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.

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

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

=== 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.
|
|
|
|
2::
|
|
The pname:maxPerStageResources must: be at least the smallest of the
|
|
following:
|
|
+
|
|
* the sum of the pname:maxPerStageDescriptorUniformBuffers,
|
|
pname:maxPerStageDescriptorStorageBuffers,
|
|
pname:maxPerStageDescriptorSampledImages,

|
|
limits, or

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

3::
|

See

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 [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).

==== Compatible formats of planes of multi-planar formats
|
|
|
|
Individual planes of multi-planar formats are _compatible_ with single-plane
|
|
formats if they occupy the same number of bits per data element.
|
|
In the following table, individual planes of a _multi-planar_ format are
|

compatible with the format listed against the relevant plane index for that
|
|
multi-planar format.

==== 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.

.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_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_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.

.Interpretation of Compression Scheme
|
|
[width="95%",cols="2,10",options="header"]
|
|
|====
|
|
| Compression scheme | Description
|
|
| etext:BC | Block Compression. See <<appendix-compressedtex-bc>>.
|
|
| etext:ETC2 | Ericsson Texture Compression. See <<appendix-compressedtex-etc2>>.
|
|
| etext:EAC | ETC2 Alpha Compression. See <<appendix-compressedtex-etc2>>.
|
|
| etext:ASTC | Adaptive Scalable Texture Compression (LDR Profile). See <<appendix-compressedtex-astc>>.
|
|
|====
|
|
|
|
ifdef::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.

|
|
|
|
|
==== 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.

|
==== 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.

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.
|

== 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.

corresponding to slink:VkImageCreateInfo::pname:format.
|
|
* pname:type is a elink:VkImageType value specifying the image type,

|
|
|
|
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.

====
|

|
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

=== 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 and
|
|
pname:format is a floating- or fixed-point color format, 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.

|
include::../api/structs/VkExternalFencePropertiesKHR.txt[]
|
|
|
|
* pname:exportFromImportedHandleTypes is a bitmask of
|
|
elink:VkExternalFenceHandleTypeFlagBitsKHR indicating which types of
|
|
imported handle pname:handleType can: be exported from.
|
|
* pname:compatibleHandleTypes is a bitmask of
|
|
elink:VkExternalFenceHandleTypeFlagBitsKHR specifying handle types which
|
|
can: be specified at the same time as pname:handleType when creating a
|
|
fence.
|
|
* pname:externalFenceFeatures is a bitmask of
|
|
elink:VkExternalFenceFeatureFlagBitsKHR indicating the features of
|
|
pname:handleType.
|
|
|
|
If pname:handleType is not supported by the implementation, then
|
|
slink:VkExternalFencePropertiesKHR::pname:externalFenceFeatures will be set
|
|
to zero.
