[[limits]]
= Limits

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

[NOTE]
.Note
====
Limits are reported via the basic slink:VkPhysicalDeviceLimits structure, as
well as the extensible structure sname:VkPhysicalDeviceProperties2, which
was added in `<<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 structures 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.

  * pname:pNext is `NULL` or a pointer to an extension-specific structure.
  * [[limits-primitiveOverestimationSize]] pname:primitiveOverestimationSize
    is the size in pixels the generating primitive is increased at each of
    its edges during conservative rasterization overestimation mode.
    Even with a size of 0.0, conservative rasterization overestimation rules
    still apply and if any part of the pixel rectangle is covered by the
    generating primitive, fragments are generated for the entire pixel.
    However implementations may: make the pixel coverage area even more
    conservative by increasing the size of the generating primitive.

  * [[limits-maxExtraPrimitiveOverestimationSize]]
    pname:maxExtraPrimitiveOverestimationSize is the maximum size in pixels
    of extra overestimation the implementation supports in the pipeline
    state.
    A value of 0.0 means the implementation does not support any additional
    overestimation of the generating primitive during conservative
    rasterization.
    A value above 0.0 allows the application to further increase the size of
    the generating primitive during conservative rasterization
    overestimation.

    pname:extraPrimitiveOverestimationSizeGranularity is the granularity of
    extra overestimation that can be specified in the pipeline state between

    A value of 0.0 means the implementation can use the smallest
    representable non-zero value in the screen space pixel fixed-point grid.

  * [[limits-primitiveUnderestimation]] pname:primitiveUnderestimation is

    culled and the provoking vertex attributes and depth value are used for
    the fragments.
    The primitive area calculation is done on the primitive generated from
    the clipped triangle if applicable.
    Zero area primitives are backfacing and the application can: enable
    backface culling if desired.

  * [[limits-degenerateLinesRasterized]] pname:degenerateLinesRasterized is
    false if the implementation culls lines that become zero length after
    they are quantized to the fixed-point rasterization pixel grid.
    pname:degenerateLinesRasterized is true if zero length lines are not
    culled and the provoking vertex attributes and depth value are used for
    the fragments.

  * [[limits-fullyCoveredFragmentShaderInputVariable]]
    pname:fullyCoveredFragmentShaderInputVariable is true if the
    implementation supports the SPIR-V builtin fragment shader input
    variable FullyCoveredEXT which specifies that conservative rasterization
    is enabled and the fragment area is fully covered by the generating
    primitive.

  * [[limits-conservativeRasterizationPostDepthCoverage]]

    implementation supports conservative rasterization with the
    <<shaders-fragment-earlytest-postdepthcoverage,code:PostDepthCoverage>>
    execution mode enabled.

    the coverage after the early per-fragment depth and stencil tests are
    applied even when conservative rasterization is enabled.

1::
    The *Limit Type* column specifies 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 <<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_EXT_descriptor_indexing[]
9:: The ptext:UpdateAfterBind descriptor limits must: each be greater than
    or equal to the corresponding ptext:non-UpdateAfterBind limit.

In addition to the minimum capabilities described for (<<limits, Limits>>)
above, implementations may: support additional multisampling capabilities
specific to a particular sample count.

To query additional sample count specific multisampling capabilities, call:

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

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

--

[open,refpage='VkMultisamplePropertiesEXT',desc='Structure returning information about sample count specific additional multisampling capabilities',type='structs']
--
The sname:VkMultisamplePropertiesEXT structure is defined as

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

  * pname:sType is the type of this structure.
  * pname:pNext is `NULL` or a pointer to an extension-specific structure.
  * pname:maxSampleLocationGridSize is the maximum size of the pixel grid in
    which sample locations can: vary.

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

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
sname:VkMultisamplePropertiesEXT::pname:maxSampleLocationGridSize must: be
greater than or equal to the corresponding members of
sname:VkPhysicalDeviceSampleLocationsPropertiesEXT::
<<limits-maxSampleLocationGridSize,pname:maxSampleLocationGridSize>>,
respectively, otherwise both members must: be `0`.
