* Happy 50th Lunar Landing Day!
* Update release number to 116.
Internal Issues:
* Clarify that flink:vkCmdBeginQuery is the same as
flink:vkCmdBeginQueryIndexEXT with index = 0, and that
flink:vkCmdEndQuery is the same as flink:vkCmdEndQueryIndexEXT with
index = 0 (internal issue 1735).
* Clarify that when copying the depth aspect between buffers and images
via slink:VkBufferImage Copy, the depth values in buffer memory must be
in range if the `<<VK_EXT_depth_range_unrestricted>>` extension is not
enabled (internal issue 1737).
* Minor language tweaks in the <<spirvenv-module-validation, Validation
Rules within a Module>> section (internal issue 1744).
* Change the slink:VkPhysicalDeviceFloatControlsPropertiesKHR structure in
the `<<VK_KHR_shader_controls>>` extension. This is a rare case of
breaking the interface of an existing extension to acknowledge the
reality of divergent vendor implementations that could not be described
properly otherwise, and the breaking change is considered acceptable
given the expected low use of the extension (internal issue 1734).
Specific changes:
** Added the slink:VkShaderFloatControlsIndependenceKHR enumeration to
describe the three possible behaviors.
** Renamed pname:separateDenormSettings to
pname:denormBehaviorIndependence.
** Renamed pname:separateRoundingModeSettings to
pname:roundingModeIndependence
* Add a missing valid usage statement for
slink:VkQueryPoolCreateInfo::pname:queryCount (internal issue 1742).
* Update the `<<VK_NV_shading_rate_image>>` appendix to list all
interfaces defined by the extension.
* Add a valid usage statement to
slink:VkWriteDescriptorSetAccelerationStructureNV to clarify that
acceleration structure descriptors must be top level structures.
New Extensions:
* `<<VK_EXT_subgroup_size_control>>`

= 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.

is the size in pixels the generating primitive is increased at each of

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

However implementations may: make the pixel coverage area even more

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

overestimation.

Otherwise the implementation only supports triangle primitives.

pname:degenerateTrianglesRasterized is true if these primitives are not

|
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.

== 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 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:
|

pname:maxPerStageDescriptorStorageBuffers,

limits, or

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).
