[[limits]]
= Limits

_Limits_ are implementation-dependent minimums, maximums, and other device
characteristics that an application may: need to be aware of.

ifdef::VK_VERSION_1_1,VK_KHR_get_physical_device_properties2[]
[NOTE]
.Note
====
Limits are reported via the basic slink:VkPhysicalDeviceLimits structure as
well as the extensible structure sname:VkPhysicalDeviceProperties2, which
was added in `apiext:VK_KHR_get_physical_device_properties2` and included in
Vulkan 1.1.
When limits are added in future Vulkan versions or extensions, each
extension should: introduce one new limit structure, if needed.
This structure can: be added to the pname:pNext chain of the
sname:VkPhysicalDeviceProperties2 structure.

[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 {plus} 1, 2 {times}
pname:size - 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 smallest possible number of bits ends up with the specified
range.
====

    If pname:fragmentShadingRateNonTrivialCombinerOps is ename:VK_TRUE,
    implementations should: report this as ename:VK_TRUE.

[NOTE]
.Note
====
Multiplication of the combiner rates using the fragment width/height in
linear space is equivalent to an addition of those values in log2 space.
Some implementations inadvertently implemented an addition in linear space
due to unclear requirements originating outside of this specification.
This resulted in <<limits-fragmentShadingRateStrictMultiplyCombiner,
pname:fragmentShadingRateStrictMultiplyCombiner>> being added.
Fortunately, this only affects situations where a rate of 1 in either
dimension is combined with another rate of 1.
All other combinations result in the exact same result as if multiplication
was performed in linear space due to the clamping logic, and the fact that
both the sum and product of 2 and 2 are equal.
In many cases, this limit will not affect the correct operation of
applications.

== 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 specifies the limit is either the minimum limit
    all implementations must: support, the maximum limit all implementations
    must: support, or the exact value 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 <<limits-maxViewportDimensions,pname:maxViewportDimensions>> for the
    required: relationship to other limits.

4::
    See <<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 minimum ptext:maxDescriptorSet* limit is _n_ times the corresponding
    _specification_ minimum ptext:maxPerStageDescriptor* limit, where _n_ is
    the number of shader stages supported by the slink:VkPhysicalDevice.
    If all shader stages are supported, _n_ = 6 (vertex, tessellation
    control, tessellation evaluation, geometry, fragment, compute).

ifdef::VK_VERSION_1_2,VK_EXT_descriptor_indexing[]
9::
    The ptext:UpdateAfterBind descriptor limits must: each be greater than
    or equal to the corresponding ptext:non-UpdateAfterBind limit.

ifdef::VK_KHR_portability_subset[]
10::
     If the `apiext:VK_KHR_portability_subset` extension is enabled, the
     required minimum value of pname:maxVertexInputBindings is code:8.

To query additional multisampling capabilities which may: be supported for a
specific sample count, beyond the minimum capabilities described for
<<limits, Limits>> above, call:

include::{generated}/api/protos/vkGetPhysicalDeviceMultisamplePropertiesEXT.txt[]

  * pname:physicalDevice is the physical device from which to query the
    additional multisampling capabilities.
  * pname:samples is a elink:VkSampleCountFlagBits value specifying the
    sample count to query capabilities for.
  * pname:pMultisampleProperties is a pointer to a
    slink:VkMultisamplePropertiesEXT structure in which information about
    additional multisampling capabilities specific to the sample count is
    returned.

include::{generated}/api/structs/VkMultisamplePropertiesEXT.txt[]

  * pname:sType is the type of this structure.
  * pname:pNext is `NULL` or a pointer to a structure extending this
    structure.
  * pname:maxSampleLocationGridSize is the maximum size of the pixel grid in

If the sample count for which additional multisampling capabilities are
requested using fname:vkGetPhysicalDeviceMultisamplePropertiesEXT is set
in sname:VkPhysicalDeviceSampleLocationsPropertiesEXT::
<<limits-sampleLocationSampleCounts, pname:sampleLocationSampleCounts>> the
pname:width and pname:height members of
