Required_Limits(3)

Description

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, 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 maxPerStageResources must be at least the smallest of the following:

the sum of the maxPerStageDescriptorUniformBuffers, maxPerStageDescriptorStorageBuffers, maxPerStageDescriptorSampledImages, maxPerStageDescriptorStorageImages, maxPerStageDescriptorInputAttachments, maxColorAttachments limits, or
128.

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

3

See maxViewportDimensions for the required relationship to other limits.

4

See viewportBoundsRange for the required relationship to other limits.

5

The values minInterpolationOffset and maxInterpolationOffset describe the closed interval of supported interpolation offsets: [minInterpolationOffset, maxInterpolationOffset]. The ULP is determined by subPixelInterpolationOffsetBits. If subPixelInterpolationOffsetBits is 4, this provides increments of (1/2⁴) = 0.0625, and thus the range of supported interpolation offsets would be [-0.5, 0.4375].

6

The point size ULP is determined by pointSizeGranularity. If the 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 lineWidthGranularity. If the lineWidthGranularity is 0.0625, the range of supported line widths must be at least [1.0, 7.9375].

8

The minimum maxDescriptorSet* limit is n times the corresponding specification minimum 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).

9

The UpdateAfterBind descriptor limits must each be greater than or equal to the corresponding non-UpdateAfterBind limit.

11

maxFramebufferAttachments must be greater than or equal to two times maxColorAttachments (for color and resolve attachments) plus one (for the depth/stencil attachment), or else must be equal to 2³²-1.
